Final Project

For this semester we are trying a single project to be selected from the "physical sciences" and presented at a "Science fair" during the Final exam period in Finals week.

Two parts:

The project will be based on the content taught in grades 3-8. (Note Science Content Standards for California Public Schools [K-8]. Condensed version and matrix and Science Frameworks which may be accessed via the Redwood Science project page:

Teacher content knowledge (what CSET tests) vs. student content knowledge


Investigations-Chemical Change

S + O2 -> SO2

C(H2O) + O2 -> CO2 + H2O

Candle, test-tube and water

CH4 + 2 O2 -> CO2 + 2 H2O

Vinegar and baking soda

H+ + HCO3- -> H2CO3

which in turn decomposes immediately

H2CO3 -> H2O + CO2
