1. The basics
By Mr. M

3. Theory or Law
A theory can be used for predictions, but may not actually be true
A theory does not have enough proof to be completely true

4. Theory or Law
A law is always true
A law is a fact

5. What You Observe
If your observation is a description (that leaf is green) then your observation is qualitative
If your observation is a measurement (that leaf is two inches across) then your observation is quantative

6. Measurements
All measurements have two parts
A number
A unit

7. To change any three variable equation
A= B × C
B= A ÷ C
C = A ÷ B

8. Density =
D = m ÷ v

9. Final volume – original volume V = Vf – V0
Water Displacement
Final volume – original volume V = Vf – V0

10. Converting ° C to Kelvin

11. Converting ° C to ° F

12. T is theoretical (real value) E is experimental (your value)
Percent error
T is theoretical (real value) E is experimental (your value)

13. Percent Yield

14. Speed
Distance ÷ Time

15. Acceleration
Speed ÷ Time

16. Force
Mass x Acceleration

17. Electricity
V = I x R R series = R1 + R2 + … 1/R parallel = 1/R1 + 1/R2 + … I = charge / time

18. (mass of part ÷ mass of the whole) × 100
Percent Composition
(mass of part ÷ mass of the whole) × 100

19. Work
Force × distance
