Question: How does a catalyst work?

The elements of this template are required to submit your project proposal. Feel free to change the layout to your liking - Elements in red are optional - let us know if you are having trouble

Hypothesis: I predict when a catalyst is added to a reaction it speeds up the reaction.

Our Experiment

Materials: 

• Active dry yeast
• Warm water
• Dishwashing liquid
• Tablespoon measuring spoon
• Hydrogen peroxide - 6%
• Funnel
• Soda bottle
• Food coloring
• Tray

---

Safety Procedures

<Explain in detail any precautions>
safety procedure 1: don't look above the bottle when the reaction is going on because it will get into your eyes
safety procedure 2: don't touch the bottle after the reaction because it is hot
safety procedure 3: do the experiment on a tray so you don't ruin a table

Procedure:

Detail steps so anyone can reproduce this at school or home
Use a numbered list

1. Place the soda bottle in the middle of the tray and put the funnel into the opening.
2. Pour 1 tablespoon of yeast into a cup and add 3 tablespoons of warm water and stir - set aside.
3. Pour a half cup of hydrogen peroxide into the bottle.
4. Pour 1 tablespoon of dishwashing liquid into the bottle and stir to mix.
5. Choose food coloring of choice and add 4 drops of color in total to drip down the inside of the bottle.
6. Now add the yeast mixture.
7. Remove funnel.
8. step back and enjoy.

Special Needs:
Goggles,experiment should be near a sink

The Science behind it

The yeast is a catalyst and speeds up the reaction so the foam shoots out of the bottle.
A catalyst when added to a reaction speeds up the reaction.

Conclusions

a catalyst speeds up a reaction
