Title: The Scientific Method
Purpose: What do you want to learn/find out?
|How can we change the speed of the reaction between Hydrogen Peroxide and yeast?
Hypothesis: Try to predict the answer to the problem. Another term for hypothesis is ‘educated guess’. This is usually stated like ” If I…(do something) then…(this will occur)
|Maybe if I mixed the hot water and yeast smooth then it would react with a big explosion.|
Materials: List everything you will need to conduct your experiment.
|Hydrogen peroxide,yeast,warm water,food colouring (o),dishwashing liquid.|
Experiment procedure: The fun part! Design a test or procedure to confirm or disprove your hypothesis. Write down each step so that someone else could do the same experiment.
|1. Pour hydrogen peroxide into the bottle and add dish soap and food colouring.
2. Put yeast in a separate cup and put 3 tablespoons of warm water into the yeast and mix the yeast with a spoon.
3. Pour the hydrogen peroxide into the yeast and watch it explode.
Analysis/Data: Record what happened during the experiment.
|If I didn’t leave the cup with yeast out too long, then it would make a bigger explosion.
Also, we should have added more hot water to the yeast, so it could make a bigger explosion.
When we put the hydrogen peroxide in the yeast it made a foamy and fizzy reaction.
Conclusion:Review the data and check to see if your hypothesis was correct.
