Use+of+Energy

For an experiment we could see what happens when a seed is put in sunlight and given water each day versus a seed that is not given sunlight or water (the needs of living) to see how its growth is when not obtaining energy. We could also do something with this same ideal but with different substances. We could possibly do something like two teams, one person out of the one team eats a power bar and the other from the other team does not. Then, they are both given a math problem and see who solves it quicker, the one who had nothing to eat and obtained no energy or the one who was just given some energy. The other two could record it with stopwatches for their partner in their group. Then the partners could switch.

I like the power bar idea, but instead we could measure a runners average racing time, and see if they run faster if they eat a power bar ahead of time.

Our idea on using the balloon lab is good, we need to do this by tomorrow. But, in the lab werent we supposed to leave the balloons out for 24 hours, we wouldn't be able to do that since we have the test on Thursday. -Pat C We have use of energy so we need to conduct the balloon lab. We are following almost step by step of the balloon lab but with a few changes. So far every thing is going well. -James M

Yeah. The balloon lab is great...but it believe we're supposed to leave the balloons out for 24 hours because in the original experiment, it says to take data after 24hours. Here is our lab so far.

Hypothesis: If the unknown substances are living things, then they will demonstrate a use of energy.

Materials: -Three test tubes with unknown substances -Sugar -Water -Balloons -Bromothymol blue -Glucose test strips

Procedure: 1.) Label all test tubes with completely unknown substances (A,B,C,D). Test tube A,B,and C should contain the unknown substances, Test tube D should not contain any unknown substances(should be your control) 2.) Add 1 gram of sugar to every test tube. 3.) Put an equal amount of water in each test tube. The amount should be 1/2 of the test tube. 4.) Mix each test tube thoroughly. 5.) Then, test the glucose strip in each test tube for 30 seconds and record the data in a table. 6.) Place a balloon over each test tube and record results in a table. 7.) Write time of initial set up. 8.) Then, record your observations after 24 hours for the balloon results. 9.) Test the glucose strips again after 24 hours.10.) Fill all inflated test tubes with bromothymol blue. 11.) Carefully remove the balloon that are inflated, make sure not to release contents inside the balloon. 12.) Squeeze contents out of balloon into a test tube of bromothymol blue. 13.) Gently mix test tube and observe and record any color changes in a table.
