• If winds are stronger then soil erosion will decrease because wind causes erosion.
• If areas flood more then soils will erode more because flooding causes erosion.
• If plants with deeper roots are grown, then less soil will be eroded because deeper roots hold soil in place.
• If darker soils are more dense than lighter soils, then areas with with darker soil will have less erosion because denser soils prevent erosion.

Read the experimental problem below. Select the hypothesis that should be used for this experiment. Problem: How does wind speed affect the distance I can kick a soccer ball?

• The ball will travel further in the wind.
• The ball will travel a shorter distance in the wind.
• If the wind is strong, then the ball will travel a shorter distance due to drag.
• If the distance the ball travels is shorter, then the wind is weak because weak winds don't move balls.

Information gathered by using one of the five senses is called a/an ____________.

• observation
• inference
• hypothesis
• control

In an experiment we are testing how radiation affects plant growth. What is the control set-up for the experiment?

• Five plants of the same species, with the same amount of sunlight and water, grown in the classroom with the radiation.
• Five plants of the same species, with the same amount of sunlight and water, grown in the classroom without the radiation.

Which of the following statements is an inference?

• The apple is red.
• The block has a mass of 19.6 grams.
• The block is floating because it is less dense than water
• The block has a volume of 26.6 mL.

Mr. Buckley wants to study how adding extra water affects the number of roses grow on his plants. Identify the variable in this experiment.

• Type of Soil
• Amount of Water
• Amount of Sunlight
• Air Temperature
