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)

If we added least yeast and added more hydrogen peroxide.

Materials: List everything you will need to conduct your experiment.

Add the hydrogen peroxide into a plastic bottle  2. Add the dishwashing liquid 3. Add food colouring 4. Mix it all up  5. Put the yeast in a plastic cup with warm water 6. And mix it  7. Put  the hydrogen peroxide, dishwashing liquid, and food colouring in to the the cup

 

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.

Plastic bottle  Plastic cup Hydrogen Peroxide Dishwashing liquid Food colour Yeast Warm water 2-4 Tea-spoon

Analysis/Data: Record what happened during the experiment. 

When we poured the hydrogen peroxide into the yeast and warm water we thought the experiment would explode but it didn’t, it just grew. Then we got to play with it  and our hands turned pink.

 

Mentos and diet coke eruption 

 

Today Room 1 and 5 did a science experiment together. We put 4 mentos pieces into a bottle of diet coke. As the Mentos candy sinks in the bottle, the candy causes the production of more carbon dioxide bubbles and the rising bubbles react with carbon dioxide. The diet coke erupted like a volcano.
