The liquid one top is olive oil so that would be the most dense liquid and the other 2 liquids are water which is inbewteen and dawn dish soap which is on the bottom.

One physical change that I observed in this experiment was the ice melting. This is a physical change because the chemical identity didn't change.

I also observed another physical change, the water in the cup turning into vapor and becoming a cloud.

A physical change was when the water was boiling in the pot.
Another physical change was where the ice melted.

1) A physical property of baking soda is the texture which is powdery.
2) When I combined the baking soda and vinegar, the substance fizzed and bubbled and the substance became clumped and not powdery
3) I didn't find this challenging, although I did find this fun.

1) A physical property of the baking soda is how fine it is, and it's texture
2) A chemical change that occurred was when the baking soda and vinegar reacted with each other, creating fizzing.
3) Something that was a little challenging was getting the correct amount of vinegar so that the fake snow had the right texture.

One of the materials i used was baking soda a physical property of the baking soda is the texture of like a powder and the color of white. A chemical change that happened in this experiment was when i added the vinegar and it started fizzing and got all bubbly. And i dint find anything in the experiment challenging at all it was really easy.

The ingredients in this experiment were vinegar and baking soda and a chemical property that happened was that when they mixed together it made a bubbling and fizzing substance. One physical change that happened in this experiment was that the baking soda and vinegar binded together into one substance.  There wasn’t really anything challenging about this experiment. Although it was somewhat hard to get the exact amount of the ingredients.

It started boiling and because it was hot.
The cloud was just steam from the hot water. Which means the substance never changed.

Identify one physical or chemical property of one of the materials you used in this experiment. Identify the material and explain why you think it is this type of property.
One of the materials used in this experiment is the baking soda. One of the physical properties of the baking soda is the texture.
Identify one physical or chemical change that happened in this experiment.  Explain why you think it is this type of change based on what you observed while completing the experiment.
One chemical change that happened during this experiment was when the vinegar was introduced to the baking soda. When this happened, there was fizzing and bubbling.
What part of the experiment was most challenging?  Why?
I didn’t find this experiment challenging but one of the harder things to do was getting the exact amount of baking soda required because I kept accidentally pouring either too much or too little.

I found that the vinegar and salt worked the best to clean the penny. One of the materials I used is salt and a physical property of salt is that it is white and has a grainy texture. a physical change that happened is that the pennies changed from a dirty penny to a clean shiny penny. There wasn't any thing challenging about this experiment

1) One physical property of the baking soda is It is powdery
a) One chemical property of the vingar is When mixed with baking soda it bubbles up and gets foamy
2) One chemical change was when I added the vinagr the baking soda reacted with it and foamed and bubbled up
3) their wasnt a supper hard part all of it was easy
And the third one was the best :)

1)One physical property is the water boiling when it became hot.
2)One physical change is when the cloud was formed because that is still just water, and you did not really make anything new, because even though it's now a cloud, it is still water. Also, you could try and get the cloud back to water, and you could do it.

1. Identify the most dense liquid in your layering column and explain how you know.  Honey it stayed on the bottom and nothing went below it.

2. Identify the least dense liquid in your layering column and explain how you know.  Vegetable oil it floated to the top.

3. Is density a physical property or chemical property of matter?  Explain your thinking. Physical because the substances aren’t having a reaction to each other it is just something that describes the substance.

4. Identify one physical or chemical change that happened in this experiment.  Explain why you think it is this type of change based on what you observed while completing the experiment. How do you know?   A physical change that happened is the color of the water changed. This is a physical change because it is still water the color just was a little tinted, this probably happened because of when I added it, the other substance color might have mixed a little .

from top to bottom it goes- vegetable oil, water(its a little tinted), maple syrup, and honey.

1. One chemical property of an ingredient I used during the experiment is reactivity. The ingredient I used was baking soda, and it has a strong reactivity with vinegar (which was also another ingredient I used).
2. One chemical change that happened during the experiment was when I mixed baking soda and vinegar. The baking soda and vinegar reacted with one another and created fizzling bubbles.I know that it was a chemical change because creation of a new substance is a sign of a chemical reaction, and when the baking soda and vinegar mixed, they created a new substance: the bubbles.
3. There was nothing really challenging about this experiment except for the fact that it was a waste of baking soda.

I think its still a physical property because it just changed color and froze. Changing of the color is a example of a physical property. The hardest part of the assignment was when I should take it out.

1.  One physical property of the water was that was boiling (very hot), and a the other form of water used in the experiment was in a different physical state. (ice)

2. One physical change that happened in this experiment is that the water turned from a liquid into a gas (water vapor) inside the jar, which created the cloud. Another physical change was when I mixed the food coloring with the water to make it blue.

# data[].attributes.body
one physical change is the water boiling and one chemicals change is the hair spray mixing with the food dye

# data[].attributes.body
its  physical change because there was no reaction to the substances.

# data[].attributes.body
one physical change was the texture of the baking soda changed and there were no chemical changes

1.  One physical change in this experiment is that when you mixed the red and blue water, the color changed to purple. Color is an example of a physical property.
I know this was a physical change because there were no signs of chemical reaction other than the color change.  Chemical changes have more than 1 sign.
