CAST Review #1

You will be taking a state test soon covering science knowledge from 6th-8th grade. We will begin reviewing material and some of the kinds of questions you will see. Even if you don't remember the material, you can still use test taking skills to increase your chances of getting the answer correct. Check all the things you could do on a test question to help you get the answer correct.

• Read the question carefully several times to identify what are they actually asking

• eliminate answer options that are definitely not possible

• take deep breaths to get as much oxygen to your brain as possible (increase your brain activity)

• study the graphs or data charts...often the answers can be found by simply reading the data provided

Answer explanation

These are are research proven ways you can use to "beat" the test and improve your test taking skills. You can learn skills to help you do better on tests.

If you are wondering if this test will be a graded assignment in science....

• Yes this will be graded, but for completion, not by your score on the test.

• Don't check this one it's wrong.

The graph below shows the movement of an object at several points in time. What is the average speed of the object?

• 0.5 meters per minute

• 2 meters per minute

• 25 meters per minute

• 50 meters per minute

Answer explanation

The first lattice point is (5,10). So, in 5 minutes, the object has traveled 10 meters. Because this is a proportional relationship, we can divide y by x. 10/5 = 2, so the slope is 2 meters/minute.

Review topic: Rate of change/slope
