we first learned about the movement of a hexbug. We made a tunnel with obstacles, the movement of the hexbugs determines its behavior. Our experiment shows us how a hexbug would behave under certain circumstances.

The experiment also show that an hexbug represent organism in our experiment. Secondly we learned on how our heartbeat works. We did a experiment on our heart beat and

breathing through a straw slows down our heart beat. Thirdly we did an experiment on how closing and opening our eyes affect our reaction time. first we closed our eyes and then we dropped the ruler to see how fast our reaction is. We did it three times then we moved on to opening our eyes and see how fast we can catch the ruler, Then we we wrote down on a chart. The last activity we exprimented on Carbon dioxide production. We use the bromothymol water to mix the liquid into color by blowing through a straw. After we blow each straws in each different color of bromothymol water, we put the baking soda inside the water and it turns back to blue which is a surprising reaction in result.

So far, activity #1 was about the hexbug. A bug that contains energy and a battery to vibrate in order to move. We have learned that each bug have its own way of moving. One of the hexbug moves in circular motion,and the other one move straight forward in motion. Activity #2 was to investigate the effect of breathing through a straw and without breathing through the straw. We have learned that breathing through a straw is harder when your doing it with different exercise, it is also hard to concentrate. Activity #3 was to investigate carbon dioxide production. Through this experiment we learned that using tap water and Bromothyol need carbon dioxide to change its color. Mixing tap water and the solution turns it blue. Using a straw and breathing through it, shows that the carbon dioxide ( that we're exhaling through the straw ) changes the color. Activity #4 was to investigate reaction time. Using a ruler, while doing different poses gives us different reaction time. We learned, by doing those different poses its either missing the ruler or catching it at a quick reaction.

From activities 1-4 we have learned how a hex bug works, and we understand how living things interact with each other, as for the heart rate activity, it shows how different people's heart rate reacts to different exercises, we did different controls first we did the exercises without the straw, then we did it with a straw to see how difficult it is with using straw. The next activity we experimented on Carbon dioxide production, seeing how the color changes due to our carbon dioxide, the color changed, due to us blowing through a straw into the bromothymol water to change it into a lime green color and changing back to its original color with baking soda. Then for the reaction time we have learned that reaction can be based on age, height, and position.

Overall what we learned from all the experiments we did. We learned that hexbug are bug like machines that contains a battery, from the amount of force the battery contains it causes it to vibrate and move on its own. The rate of heartbeat, from this experiment it shows that breathing through your nose is more efficient than breathing from your mouth, it causes your heart rate to slow down and make you more calm. However breathing from your mouth while exercising causes your muscles to tense up, breathing heavily, and causing you to get tired easily. Carbon dioxide, its more focused on the Ph level of water containing C02, this experiment is mostly focused on the breathing techniques and how long each will take to turn the water yellow. Lastly is reaction time, this experiment tells us how fast our nerves react due to being under tension .This experiment is also based on hypothesis, age, time, and speed. Thus this is all we've learned throughout all the experiments we did in Griselda Muut's class

So far,from observing through the activities 1-4,we've learned many things. We've learned about investigating reaction time,for example, how fast your catching the ruler. We also learned about characteristics of life,how the hex bug can almost act like an insect. The other two lessons are investigating heart rate and carbon dioxide production. Learning these things are fun and watching how it change colors and stuff.

In activity#1,the Hexbugs displayed movement as they vibrated and aimlessly darted across the classroom.In activity#2,our heart was tested as we breathed normally and then through a straw.In activity#3,we tested the reaction of Bromothymol blue and carbon dioxide and how it can change the Ph of water.In activity#4,we learned that old age actually contributes to people's reaction time/reflexes.

so far from the activitys from 1-4.Me and my group learned how each activity has its own similarities for example activity #1 its about hex bugs which they look like bugs which roam around wildly finding ways to go too.for activity#2 its about heart rate which is about pulse and how your heart rate reacts so fast.On activity#3 is all about carbon dioxide.we see how carbon dioxide work and reacts to life.for activity#4 is about investigating reaction time and how time reacts to life so fast.all of this activity is basically about characteristic of life.

Me and my group were given hexbugs as a substitute for the characteristics of life we observed and watched the bugs crawl around.we even made a pathway for the bugs to crawl around we learned that the hexbugs can be seen as a part of life and the environment around you. so far the hexbugs were a good example for activity.they were like animals roaming around the environment we made for them.they were like ants or little bugs crawling around.wich taught us a lot about the characteristics of life.

-So far from observing through activities 1-4. I learned how things can be similar to a living thing but it isn't living. For example, how a hex bug robot reminds us of a insect but actually isn't, How breathing through a straw can effect your heart rate, how breathing on carbon dioxide can change the colors and its so interesting to watch. Lastly, I learned the difference in people and how they react to something differently.

In Activity 1 it was about "Hexbug Robot" that acts like cells which is the "Basic Unit of Life". It climbs and travels like cells traveling in your veins. An hexbug wasn't a living thing but it moves like an insect.

In Activity 2 we did "Investigating Heart Rates" and we learned that breathing through straws will slow down your heart rate. On Activity 3 we learned about carbon and how it reacts to chemicals, it basically changes the color or the chemical and adding baking soda will change it back. In Acitvity 4 we experimented on how fast we can react to catch fallen objects, we learned that it depends on how fast your brain reacts and send out message out message to the rest of the body parts.
