Warm Up # 1-1 – August 24• Answer all of the questions to the best of your ability in complete sentences .

Three groups of students decided to design experiments to learn more about the process of evaporation. One group of students used the four different containers shown below.

The students poured 100 milliliters of water at 20°C into each container. The containers were placed side by side on a table near the window for 24 hours. The next day the students used a graduated cylinder to measure the amount of water left in each container.

1. Write one question the students were probably trying to answer in their investigation.

2. Explain why the students put the containers side by side instead of putting each container in a different room.

For the example below find the independent variable, dependent variable, and constants.Jack wants to find out which laundry detergent cleans the best. So he takes a cotton sheet and cuts it up into equal squares. He stains four squares with chocolate, and four with grape juice. He washes one of each of the square in each of the 3 detergents. One from each set of squares is washed in water alone. For each wash load he used; the same amount of water, the same amount of detergent and the same temperature of water.
