1. During the final week of this quarter, all Juniors will take the science state assessment. We will spend the first few minutes of each class doing general review.

2. 1) Sara and Jacob designed an experiment to test the effects of increased mass on the speed of a remote control car. Which of the following is the independent variable in their experiment? A) The mass added to the remote control car. B) The speed of the remote control car. C) The distance the remote control car travels D) The person driving the remote control car. Physical Science 1.1.2

4. 2) Dave and Ryan designed an experiment to determine if crushed ice cools water faster than cubed ice. The dependent variable in their experiment is A) the type of ice added to the water. B) the temperature of the water. C) the rate of temperature change. D) the final temperature of the water. Physical Science 1.1.2
