Using Chemicals to Make Pressure Nicholas Peters Winchelsea Elementary School Parksville, British Columbia

Canada-Wide Science Fair Information Grade Grouping:  4 – 6  Team Size:  1or2,  Subject Area Chemical Project Type  Experimental Project Level: Standard Project Format: Traditional Web Page

Canada-Wide Science Fair Information- continued   I’m going to demonstrate how air pressure works.

Canada-Wide Science Fair Information – Continued I used: Microsoft PowerPoint Hardware Tools I used digital  Camera and computer The Source of the Idea for my project I watched a movie – October Sky

Purpose  I am going to measure air pressure by using chemicals in bottles.

Materials Used 1.3 bottles 2.3 corks 3.9 tablespoons of baking soda 4.3 tablespoons of each chemical 5.Some thing to measure the  height of the cork.

Procedures - steps we used 1.I watched a movie 2.Made an experiment I will put the chemicals into a bottle I will then put a cork in the top of the bottle. I will finally record how high the cork goes and that tells me how much pressure I made

Hypothesis I  think that more acidy chemical will go higher

Results My results were: 1. Vinegar – went just over8 metres and didn’t make much fizz 2. Lemon – went just under3 metres and made lots of fizz 3. Tomato went 0 metres and a little bit of fizz.

My Experiment

My Project Board

Conclusion I learned that basic things plus acidy things can make air pressure.
