Identify which step of the scientific method is described

 Does the thickness of the material affect the bearing capacity?

Back

Ask a question

Front

Identify the variables in the following problem:

 Does the weight of the monster affect its sinking time?

Back

• Independent Variable: This is what you change on purpose. In this experiment, it’s the weight of the monster. You might make it heavier or lighter to see what happens.

• Dependent Variable: This is what you measure to see if it changes. Here, it’s how long it takes the monster to sink. You’re checking if the sinking time changes when the monster’s weight changes.

• Controlled Variables: These are things you keep the same so the test is fair. For example, you’d use the same kind of liquid, keep the monster’s shape the same, and make sure the water is the same depth and temperature. This way, only the weight affects the sinking time.
