## Bellwork (test review)

1. Solar oven experiment:

Students want to increase the temperature of their solar oven.. They use a solar oven from last year's group to compare to their constructed oven. Group one builds a similar oven, but changes the size of the box, keeping all other things the same.

Determine:

Independent Variable

Dependent Variable

Control

Constants

2. Convert using the Factor/Label method.

752 cm to m

25L to mL

3. What is the formula for density?

4. How many significant figures in the following numbers:

0.000620

3012

700

7002
