What he did was that he put mice in a jar for an experiment and every trial (which is three) the mouse died in the jar without it being opened once. The next thing he did for the next three trials was that he put a plant in with the mouse. What happened was that the mouse lived every trial meaning that the plant produced oxygen because the mouse exhaled Carbon Dioxide and plants use Carbon Dioxide so it was a mini Co2/O2 cycle. Joseph did this because he had a mouse problem.]]> 2017-02-23 16:46:05 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/155811756 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/155820298 The Co2/O2 cycle is the process of breathing and exhaling. In long form, when you exhale the whole cycle starts. When you exhale, it releases carbon dioxide (Co2) and then the plant takes in the Co2 and releases it as oxygen (O2).]]> 2017-02-23 17:05:36 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/155820298 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/156474352 If i place a larger jar over a lit candle, then there would be a longer burn time because fire needs oxygen to burn and a larger jar holds more oxygen for the fire.]]> 2017-02-27 16:46:16 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/156474352 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/156479098 1. Get all materials ready
2. Put on your goggles for safety
3. Place your petri dish  on a flat surface
4. Put your clay that should already be flattened out onto the petri dish 
5. Place a tea light candle onto the clay.
6. Light your match
7. Put the lit match over the candle to light it.
8. Quickly but carefully put the regular sized jar onto the clay and put a little bit of pressure onto the jar so no carbon dioxide can get out.
9. Start the stopwatch immediately afterwards.
10. Wait for the fire to dim out completely before stopping the stopwatch
11.  Now take out the jar and wash all the Co2 out of the jar with your wash cloth
12. Write the time on a piece of paper called trial 1
13.  Now repeat steps 6-11 for trial 2 and 3
14. For the larger jar light your match.
15. Put the lit match over the candle to light the candle
16. Quickly but carefully put the larger sized jar onto the clay and put a little bit of pressure onto the jar so no carbon dioxide can get out.
17. Start the stopwatch immediately afterwards
18.Wait for the fire to dim out completely before stopping the stopwatch.
19.  Now take out the jar and wash all the Co2 out of the jar with your wash cloth.
20. Write the time on a piece of paper with the label "Trial 1".
21. Repeat steps 14-20 for trials two and three without the trial 1]]> 2017-02-27 16:56:58 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/156479098 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/156790947 2017-02-28 17:06:07 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/156790947 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/156791861 2017-02-28 17:08:58 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/156791861 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/156792813 2017-02-28 17:11:45 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/156792813 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/157113497 The relationship of fire and Co2 and O2 is that when fire starts, it releases Co2 and what fire needs to keep going is O2, which is oxygen ]]> 2017-03-01 17:54:44 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/157113497 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/157114442 My personal experience with the Co2/O2 cycle is that I exhale which releases C02 and when I breath I inhale O2.]]> 2017-03-01 17:56:53 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/157114442 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/158758298 2017-03-08 18:07:40 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/158758298 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/159036140 1. Small flame and half blue half orange. 
2. The flame gradually dimmed out

2. Got smaller but didn't go out.
3. Noticed that the liquid wax was building up on the candle. Went out faster than all the other trials]]> 2017-03-09 16:40:43 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/159038198 j_reno https://padlet.com/j_reno/olznpy6swzrl/wish/159039434              In this experiment, I was testing with a regular jar, (control) and with the Larger jar (variable) to see which jar could hold more Co2 from a tea light candle. What I learned from this experiment was that a larger jar holds a lot more Co2 than a regular sized jar.
             My hypothesis was that the larger jar would hold more Co2 than the regular jar. My hypothesis was correct because with the larger jar, it lasted so much longer than the regular jar because of the Co2. The averages for both tests were: Control: 34.93 seconds and Variable: 195 seconds. Some patterns i noticed were that for the variable, they were really close besides the third trial. These results were important because now I know the difference of the time for both the control and the variable. What I discovered was that there were big differences in the times for the control and variable.
             A possible source of error could be that you might accidentally let some air in from the clay and that would lead to longer burn time. A source of error in my test that happened was when my friend was putting the jar onto the clay with the lit candle and when he was putting the clay on there were some air holes in it. The effect of that error was that there would be a little longer burn time. Some improvements next time would be to make sure there are no holes in it. Understanding errors are important for a scientist because when you find out the error, you try to fix it and go on with your experiment.
             This experiment was important to work on in relation to understanding the Co2/O2 cycle because the tea light candle releases carbon dioxide and needs oxygen to keep it lit and also the jars hold a limited amount of oxygen so that also means the fire stays lit for a limited amount of time. This experiment is important in the real world because with humans, they release carbon dioxide and take in oxygen, just like plants. For example, if you put someone in a jar and seal it, they only have a limited amount of time to breath before they die. A different experiment I would test to study the Co2/O2 cycle would be using a plant instead of a larger jar. I would choose that test because it seems fun to use a plant to make air for the fire to take in for a longer time. Learning about the Co2/O2 cycle is significant because It's interesting to see how fire needs oxygen to burn, just like animals.]]> 2017-03-09 16:43:41 UTC https://padlet.com/j_reno/olznpy6swzrl/wish/159039434
