Research Question: How does acid affect the rate of enzyme catalyzed  reactions in chicken blood?
IV: pH
DV: measure temperature 
Materials: acid, hydrogen peroxide, chicken, thermamtor, microscope, test tube
Procedure:
1. place blood in a test tube
2. thermator in test tube 
3.record temperature
4. place acid in test tube
5. record temperature in one minute intervals
Null hypothesis: acidity won't affect reaction rate
alternative hypothesis: acidity will affect reaction rate.

IV: Temperature
DV: Height of the bubbles in the test tube above the line of hydrogen peroxide.
Constants: Amount of hydrogen peroxide, mass of potatoes, placement of experiment
Null Hypothesis: Temperature will not have any affect on the rate of catalyzation of hydrogen peroxide.
Alternate Hypothesis: Temperature will have an affect of the rate of catalyzation of hydrogen peroxide.
Procedure: 
1. Place 40ml of hydrogen peroxide in 3 test tubes.
2. Place one test tube at room temp, place one test tube on ice, and place one tube next to a heater.
3. Put 1 gram of potato in each tube and let sit for 2 min.
4. Record the highest point in which the bubbles reach in each test tube. 
5. Analyze results ]]> 2017-01-27 19:38:08 UTC https://padlet.com/perkins2/uudeenc27ewr/wish/149985118 https://padlet.com/perkins2/uudeenc27ewr/wish/149985610 RQ: How does light affect hydrogen peroxide breakdown on potatoes?
IV: Different amounts of light
DV: Rate of breakdown
Materials: Potato, hydrogen peroxide, normal room light, bright light, test tube, dark place
Procedure:
1. Put pieces of potato in 3 test tube and pour hydrogen peroxide
2. Put each test tube in different light areas and time how long each one takes to react
3. Record data
Null hypothesis:  Light will have no effect on the breakdown of potato by hydrogen peroxide.
Alternative hypothesis: Light will have an effect on the breakdown of potato by hydrogen peroxide and the brightest light will cause the fastest reaction.

IV: Temp of blood
DV: Amount of oxygen bubbles
Materials: test tubes, temp probe, hot water, ice, plastic tub, peroxide
Constants: Amount of blood, amount of peroxide
Procedure: (3 trials)
1. Putting same amount of blood into four test tubes
2. Making the blood different temps by placing one test tube of blood in warm water, placing one in water with ice, placing one in hot water and one that is  room temp.
3. Record the temp of the blood
4. Place 15ml of peroxide into each test tube
5. After 1.5 mins re-check the temp of the blood
Null Hypothesis: Peroxide will have no effect on the catalyzation of different temps of chicken blood.
Alternative Hypothesis:
Peroxide will have have an effect on the catalyzation of different temps of chicken blood. ]]> 2017-01-27 19:40:15 UTC https://padlet.com/perkins2/uudeenc27ewr/wish/149985843 https://padlet.com/perkins2/uudeenc27ewr/wish/149986352 Research Question: How does the amount of acid affect the rate of catalyzation?
IV: acidity
DV: the rate of catalyzation
Constants: temperature, type of glassware, amount of potatoes
Null Hypotheses: The amount of acid does not change the rate of catalyzation.
Alt. Hypotheses: The amount of acid does change the rate of catalyzation.
Procedure:
1. Measure out the amount of potatoes and weigh them 
2. Prepare for 12 trials (3 2 drop, 3 4 drop, 3 6 drop all with 3 control trials)
3. Sit each solution for 5 minutes
4. Add x amount of hydrogen peroxide and rest for 10 minutes
5. measure height of bubbles once after 10 minutes]]> 2017-01-27 19:41:51 UTC https://padlet.com/perkins2/uudeenc27ewr/wish/149986352
