While watching the experiment, I noticed that in the cup with the cold water, the food coloring was moving very slowly, while the food coloring in the hot water, was moving much faster. The warm water moved at a medium speed. I think that with the hot water the color moved faster because, in the hot water the water molecules are moving much faster than the molecules in the cold water. The color in the warm water cup, was moving neither too fast or too slow, because the water was room temperature.  From the reactions, I am able to deduce that the thermal energy or heat transfer is convection.

# data[].attributes.body
I noticed that for the cup of hot water, the color was a lot darker and the warm water was like in between and the cold water was the lightest color.

# data[].attributes.body
I noticed that the food coloring in the hot water spread very quickly in the water. However, the food coloring in the cold water sank very slowing spreading in the water only a little bit. The food coloring in the warm water was about the middle of this and didn't spread that slow but not fast either. I think the food coloring in the hot water spread fast because since it is hot water the molecules are moving faster. I think the food coloring in the cold water spread slowly because the molecules in the water moved slowly. The warm water had food coloring moving not too fast and not too slow because it was room temperature and not cold or hot. The type of heat transfer happening was convection because I could see the colored water in the hot water flowing down them up in a circular motion. This happened because the colored water was more dense and sank, but got heated by the less dense water and rose up.

# data[].attributes.body
I noticed the food coloring was faster in the hot water than in the cold water.
I believe this is because of heat energy in the water.
The type of heat it is conventions because when the molecules move they transfer energy.

# data[].attributes.body
I noticed that the food coloring in the hot water spread most easily. The warm water cup, the food coloring spread quicker than the cold water, but slower than the hot water. I believe that the thermal energy in work here is convection, since the hot molecules move faster than cold water molecules.

# data[].attributes.body
While watching the experiment, I noticed that in the cup with hot water, the food coloring was spreading throughout the cup a lot faster than the cups with warm and cold water. However, that being said the food coloring in the warm water was moving a lot faster than the food coloring in the cold water. I think this is because water molecules in warm or hot water have more energy or move faster than water molecules in cold water. Due to the fact the food coloring in the cups are going from top to bottom, I think that this is an example of convection.

# data[].attributes.body
I noticed that the food coloring went to the bottom easily in hot water because the molecules in hot water move very fast, compared to warm or cold water.  Since the food coloring started to rise slowly after it touched the ground, I think the thermal energy is convection.

# data[].attributes.body
What I noticed is that the hotter the water, the more of a difference.  The hot water had the fastest change while the warm water had medium speed and then cold water was very slow.  They are different because the hot water has the fastest molecules while the cold molecules are slow.  I think it is convection.

# data[].attributes.body
The hot water has the most identifiable change in color. The room temperature water had the second most change in color, and the cold water had the least. When I dropped the watercolor paint, what was different was the speed of which it spread out. My theory is that since hot water has the highest temperature, there is more convection. So, the convection currents carried the paint throughout the entire cup. The cold water had the least temperature, so it had less convection.

# data[].attributes.body
I noticed as I watched the video, every cup had a different pace of mixing. For example, the "hot" cup mixed extremely fast, whilst the "warm" cup blended a bit slower. The "cold" cup barely mixed at all. My guess is that the hotter water particles move faster and are able to spread easier than the colder molecules, which have tighter particles and cannot mix as well.   The type of thermal energy was convection because the food coloring was one of the objects while the water was the other. Since they touched, the temperature had to change and so, the "hot" cup mixed the quickest.

# data[].attributes.body
When I watched the video, I noticed that when he or she put the food color in each of the cups, they all had a different reaction. The food coloring put into the cup with the hot water (in the middle) had spread faster. The food coloring in the warm water (to the left) was moving at a medium pace. And the food coloring in the cold cup of water (to the right) was moving at an extremely slow pace. I think this was happening because of the temperatures in each cup. For the hot water, the molecules were more loose and free, so they spread easier. It can be the same for the warm water, but the molecules may have not been as loose as the hot water molecules, so they moved at a slower pace. The cold water's molecules were tightly packed together, which didn't help spread the food coloring as fast, only slower. Henceforth, due to the reactions, the thermal energy or heat transfer is convection.

# data[].attributes.body
as i was doing the experiment i noticed that the hot water was very fast and it made the water very blue very fast.and with room tempter i noticed it was a little slower than hot water but i was still a good speed .and with the cooled water it was very slow it took the longest to get the water all blue . all the cups had a different speed by its self and they were all different .i really liked this experiment and i hope we can do more experiment like this one .

# data[].attributes.headline
What I noticed was, when he put the food coloring into the cups, each cup had a different reaction. I noticed, first, that the hot water had already spread throughout the majority of the cup, while the other two cups were still spreading, Next, I observed the cup labeled "warm" and the food coloring was going at an okay level. Lastly, I turned my attention to the last cup, filled with cold water. It appeared as if it wasn't moving at all, like traffic in Los Angeles. I think that we can all agree that this means that, the hotter the cup, the faster the dye can move through it. Also, I think the type of heat transfer is convection, because when he dropped the dye in the hot water, it circulated, as it does in convection.

What I noticed was that when the food coloring was put inside the different cups of water. Each of the cups had a different time for when when the die pretty much dissipated. I realized that the cold water took a long time to dissipate because its molecules are tightly packed. The hot water dissipated easily because the molecules are loose.

When the food coloring went into all of them the ones in the hot water colored much much quicker than either the warm or cold water.

# data[].attributes.body
As I was doing my experiment, I observed that the food coloring spread faster in the hot water. For the cold and warm water, the food coloring "sunk" slower. They are different because of the temperatures of the water in each cup. Therefore, based on my observations and the experiment, the thermal transfer is convection.

# data[].attributes.body
In the video, i noticed that the food coloring in the hotter water spread quicker. Since the molecules in the hotter water moves faster, the food coloring spreads faster. I believe convection is the heat the occurred when i watched the video.

# data[].attributes.body
In the video it had shown three different cups of different temperatures. In the warm cup I noticed that the flood coloring was mixing into the water quickly but not as quick as the hot water. I can conclude that depending on the temperature such as warmth it would mix faster into the water than the cold water. Due to the temperatures the circulation would be different. In the cold cup the flood color seemed to be foggy and it slowly mix but most of the water was still not mixed altogether. I believe that the molecules would move around and mix better in the hot water than the cold water. In conclusion, this video shows how convection is occurring and how effected all three different temperatures.

# data[].attributes.body
When watching the video as well as doing the experiment myself, it was already clear how the molecules were heating up and moving in a cycle. The hot water almost immediately spread the food coloring atoms and moved faster depending on the circulation due to the water being warm. Because of this cycle, I believe that convection is the heat occurrence in the experiment.

# data[].attributes.body
The three cups of different temperatures allowed the food coloring to mix at their own paces. I notices that the warmer it got, the faster it mixed. The hottest one pretty much mixed the food coloring by itself. The warm cup had food coloring that didn't mix as well as the hot water. However, the cold cup's food coloring stayed mostly together and not much of the food coloring dispersed compared to the warm cup.

# data[].attributes.body
Doing the experiment, I noticed quickly that the blue food coloring was spreading into the water faster in the hot water then in cold. In the cold water, it took longer to sink to the bottom of the cup. This experiment shows how convection works.

It is important to understand warm and cold ocean currents. It is importnt because the currents tempertures effect different things. For example, it can effect the different plants growing in the ocean, some need cold tempertures to survive while others need warm tempertures. If the tempertures change then the plants can die which causes the animals who eat those plants to starve and then die, and the effect will continue.

# data[].attributes.body
I noticed in the video that the food coloring in the hot water was able to mix and move around in the water better than the food coloring in the warm and cold water. I think they are different because the molecules were moving more in the hot water to equilibrate with the air temperature. This type of heat is convection.

# data[].attributes.body
In the experiment, I noticed that the hotter the water is, the quicker the food coloring spreads. In the hot water, the coloring spread almost immediately. In the room temperature water, the coloring took longer to spread. In the cold water, the coloring took a while to spread fully. This shows that the type of heat is convection.

# data[].attributes.body
It is important to understand hot and cold ocean currents because hot currents effect sea life a lot. For example, Penguins live in the cold, and they need cold currents to survive but as the water gets warmer they start to die. Cold currents are really important to many sea animals, counting on survival.

I think that ocean currents are important to understand because they can help us predict the weather. Since hurricanes are formed when hot water and cold water interact in a special way, we can figure out how hurricanes form, how to predict when another hurricane's going to strike, and save thousands of people.

# data[].attributes.body
During the video I watched, I saw that the hot water takes the food coloring faster than the other ones because it is melting, but the cold water, the food coloring dissolves really quickly. It makes sense that the molecules are moving constantly so that it dissolves faster, and the thermal transfer taking place in the video is convection.

# data[].attributes.body
While watching the video, I obeserved that the hotter the liquid in the glass, the quicker the food dye spread in the water. The product was different with each glass; by the end of the video, the food dye had spread completely throughout the glass of the hot liquid, however, with the cold liquid, the dye slowly expanded until it had reached the bottom. This shows that the type of heat transfer occuring in the video is convection.

# data[].attributes.body
I noticed that the food dye moved around the fastest in the hot water. Also the food dye was moving around everywhere. In the cold and warm water the food dye slowly went down to the bottom of the cup. The dye in the warm water cup did move around the cup while it was going down, but the dye in the cold water cup stayed in the middle while it was going down. The dye in the hot water made all the water blue. The dye in the warm water made not as much water blue, but it still did decent. The dye in the cold water did not make the water as blue as the warm water or the hot water. The conclusion is that the hotter the water the more faster the food dye will take over the water.

# data[].attributes.body
I saw very clearly what separated them, the cold one's food coloring took it's time. Meaning it was very slow. The hot water moved very quickly, it took a very small amount of time. Since the atoms were moving at a constant rate, I believe the the type of thermal transfer taking place is convention.

# data[].attributes.body
I notice that the in the hot water the food coloring moved more freely and the colder the water the slower the food coloring mixed with the water. I think they are different because in hot water convention is taking place and so the molecules are constantly moving. So the type of thermal transfer taking place is convention.

# data[].attributes.body
I noticed that the coloring in the cold cup sank faster because it was dense and the hot cup wasn't dense so it floated.

# data[].attributes.body
I saw that the water in the cold water sank and was more at the bottom because is was more dense. But the hot water  was less dense so it went to the top. And the Room Temp. water was about balanced.

# data[].attributes.body
In the video I noticed that for each cup there was a different reaction. In the cold cup the dye moved slowly and sank to the cup. In the warm water the dye seems to keep on moving up and down. In the hot water the dye moves freely around the cup. In the conclusion the dye hot water moves faster than in the warm and cold water. Since there was lots of movement in the dye for the warm and hot water I think the type of heat tranfer was convection.

# data[].attributes.body
When watching the experiement I observed that in the cold water the food coloring moved slower and in the hotter water it moved more sporadically and moved  more freely than the other ones. I think this happened because the colder one was acting more like a solid which limits the movement of its atoms. Even though it was still liquid I think the cold water had similar properties to the solid because of the cold state and since there was a lot of movement in the water I suggest that the type of heat transfer was Convection.

# data[].attributes.body
When the food coloring fell into the water I realized that some spreads faster or slower than other temperatures. The hot water made it spread the fastest. The food coloring inside the cold water was slower than the hot water, and the warm waters food coloring was faster than the food coloring in the cold water and slower than the food coloring in the hot water. The warm water was in between.

# data[].attributes.body
When I added a drop of food coloring into  three different temperature of water, I noticed how fast the food coloring moved in each cup. When I dropped food coloring into the cold water, I noticed how slow and steadily it spread through the cup. When the temperature goes down, the bond between the water molecules will get more tensed, so the food coloring won't be able to move through the molecules as fast.  Instead it sinks down to the bottom of the cup very slowly. On the other hand, when dropping food coloring into hot water, the dye spreads rapidly throughout the water and it blended with the water as well. When the temperature goes up the bond between the water molecules (H20), loosens up. Therefore, the dye spreads much quicker in warmer temperature. Finally, when I added a drop to the warm water, the dye spreaded not to slowly nor too fast. Between warm and cold temperature, the bond of the water molecules are not too tight nor too loose. For this reason, the dye could go smoothly but not too quickly through the water molecules. In hot water there is a lot of heat energy which allows dye to move and spread quicker. Convection allows the dye to react differently in colder or hotter temperature.

I didn't have the materials, so I watched the video. I noticed that the hot water spread faster than the food coloring in the cold or warm water. In the cold water, the food coloring sunk down and was very boring. The warm water was like a Goldilocks for this experiment because it was not too cold nor too hot, so it spread normally.

# data[].attributes.body
I noticed that right when the food coloring was dropped in each cup of water, the food coloring was diffused at different rates. The cold water diffused slower because of its cold temperature and the hot water made the coloring diffuse faster because of its tempurature.

While watching the video, I noticed that the food coloring in the hot water diffused and spread the fastest, because of the higher temperature; whereas the food coloring in the cold water diffused the slowest because of the low temperature rate. I also noticed that the in the cold water, the food coloring didn't spread as much, but just sunk down as a weight in the water. Finally, the warm water spread and sunk not too fast and not too slow, because the temperature was between hot and cold. Adding food coloring in different water temperatures will affect the diffusion rate because of the temperature of the water. (I do not know why my name shows as Anonymous)

I noticed that when I put the die in the hot water, is spread the quickest. On the other hand, when I put the food die in the cold water, it  spread the slowest.  The hot water molecules make the food die make the die move quickly, and the cold water molecules make the water move slower.  The warm water was in between the hot and cold water.

# data[].attributes.body
I noticed that the dye in the hot water disappeared the quickest, due to the waters thermal energy, causing the molecules to move faster. The dye of the cold water moved very slowly while the mild hot water dissolved at a speed that is in between the hot and cold water. Because of this, we can tell that the colder the water, the slower the molecules move.

# data[].attributes.body
I saw that the hot waters molecules were spreading  the food color the quickest, Because the waters thermal energy was causing the molecules to move faster. It was using convection. In the colder one it showed that the food dye was condensed into small balls of paint in the water,because the paint molecules were not spreading.

# data[].attributes.body
I noticed that when the hot water mixed with the food coloring the food coloring spread the quickest, and when the food coloring mixed with the cold and warm water it woved slower.

# data[].attributes.body
I noticed that when I put the food coloring droplets the hot water moved the fast and the cold water moves the slowest. Say you want to wake up with a cup of coffee or something hot, if you drink it, the caffeine and the heatness of the drink wake you up so it gets you moving faster, and I if it is a hot day, and you want a cold drink to cool down, the coolness of the drink makes you want to rest or sit down to enjoy the cool drink. In conclusion, the heat molecules makes the food coloring move faster and the cold molecules make things move slower.

# data[].attributes.body
The food coloring in the warm is slightly slow and didn't mix very well with the water. However, the food coloring in the hot water moved very fast. After sinking for a little, it slowly rose to the top, spreading the food coloring evenly. The food coloring in the cold water sank very slow, and barely mixed with the water at all. The particles in hot water may have encouraged the food coloring to spread, while the particles in cold water will prevent the food coloring to spread.

# data[].attributes.body
Looking at the video, when adding the food coloring to the water, the how water immediately mixes with the food coloring. When it comes to the warmer water, it seems to have something to do with convection, this is because, the food coloring seems to be continuously moving from the bottom to the top. Lastly, the cold water moves the slowest, it sinks to the bottom of the cup. So in conclusion, the hot water moves quicker than the warm and cold water, with the warm quickly behind. And the cold lasts. So looking at the order, the food coloring speed is determined by the temperature of the water.

# data[].attributes.body
I noticed that the hot water moves the quickest, then the warm water, and the cold water is moving very slowly. I think they are different because hot water molecules move the fastest. The cold water molecules move the slowest.

I noticed that the food dye promulgated in the hot water the fastest. In the hot water, the molecules are scattered around and  move around freely. On the other hand, the cold water was the sluggish. The molecules in the cold water are compacted together and are not scattering around like the molecules in the hot water and warm water. The mellow water is moving, but not scattered like the hot water, and not as sedate as the cold water. These are my observations of this project.

# data[].attributes.body
I noticed that the warm and hot cups of water made the food dye spread faster inside the cup, but the cold cup of water made the food dye go slower. I think they are different because each temperature level of the cups made the dye spread in unique ways. This is an example of convention.

# data[].attributes.body
I noticed that the food coloring in the hot water disseminated the fastest because particles move faster at higher temperatures. In contrast, the food coloring in the cold water sunk down before spreading because the water is cold and the diffusion rate is slow. The food coloring in the lukewarm water diffused at a pace between the hot and cold water because of its mild temperature. The food coloring spread at a different rate in each glass based on the temperature of the water

# data[].attributes.body
When I put out my 3 liquids, cold water, lukewarm water, and hot water. The hot water had the fastest molecules because the heat made it more faster. The cold one was the slowest because of the temperature. Since it is cold, the movement is less. So the hot water has the most movement, the colder one has less movement, the lukewarm is in between.

# data[].attributes.body
The pink lines on the map looked like the food coloring in the hot water. This is because the hotter the water the faster the molucules move. This is why the blue currants were not everywhere on the map. The blue currants where just like the cold water in the experiment. To conclude, the hotter something is the faster the molucules move.

# data[].attributes.body
I watched the video and tried the experiment as well. When I observed the three cups, I knew that all of them were the same type of matter. All three cups were liquid, but their level of heat were greatly different. I poured in cold water into the first cup, warm water into the second, and hot water into the third cup. As I carefully dropped the food dye into each cup, I observed carefully. Soon the hot cup rapidly moved around the cup and within seconds, the whole cup was already fully yellow. When I looked over to the cup with cold water, I saw that it was barely moving and slowly spread around. Surprisingly, most of the food dye all sank to the bottom of the cup. When I observed the cup with warm water, I noticed that it hasn't fully mixed but is partially mixed, it was in between the cold and hot cup. The cup with warn water also had most of the food coloring in the bottom but not directly going to the bottom as the cold cup did. I guessed that the cup with hot water didn't have food dye at the bottom of the cup since there was so much energy and movement in hot water. In other words, hot water has a lot of thermal energy in its water, which also means that there is more energy in the water. When there is more energy in water, it means that matter moves more quickly in the water, and the thermal energy heats up the water. Since matter moves so quickly around hot water, the energy quickly moves the food coloring around the water quickly before it sinks down to the bottom of the cup. This is why the food coloring quickly mixed with the water within seconds. On the contrary, the cup with cold water doesn't have much thermal energy or just energy. Since there isn't much energy, there isn't much movement. Energy is important to life, and us humans and other living beings have energy to help us do the simplest things. We use energy to wave our hand, walk, talk, and even think. That's why when we run, we use more movement than walking, so we use more energy. That's why we are so exhausted after we run. When I was experimenting, I added ice to warm water to create cold water. When I did this, it was called conduction, because when I added ice, I minimized the amount energy so the water lost energy, this is how the water becomes colder. When every second goes by, energy disappears from the water, making the water colder. Since there isn't much energy to move around the food coloring, all the food dye sank to the bottom, but some spread from some energy left over. The warm water is in between the cold and warm, it has a medium amount of energy. Soon more energy would enter the water from room temperature, and the dye would soon fill the whole cup. But since there is more energy, the food dye that sunk, would rise to the top and sink again. It's like a cycle, and this is called convection. On the other hand, the hot water would turn into warm water, and the food dye would all sink to the bottom. As time goes by, the three cups would all turn into warm water. This is why ovens and refrigerators were created.

# data[].attributes.body
I noticed that in the hot water was the fastest because the molucules moved faster. So the molucules moved the food coloring. The slowest was the cold water because there was very little heat which made the molucules move slower. The wasrm water was not the fastes because the waster inside the cup wasn't totally heated for the molucule to move super fast.

# data[].attributes.headline
I noticed that in the food coloring experiment the coloring were all moving at different paces. Which tells me they have something to do with the temperature because they are all moving at different paces.  The cold one is moving the slowest because there is very little heat which makes it harder to move down the water faster, but the hot water is easier to move down through the water because it has more heat and is more consistent with kinetic energy so it can move faster than the warm and cold waters. This is how convection works because the heat is traveling through the water.
