Q.1.
If you were testing materials to see whether they conduct electricity using a circuit and bulbs, what would be the dependent variable?
Q.2.
If you were testing the effect of water resistance on three different plasticine shapes, which variable would you be changing?
Q.3.
If you were testing materials to see whether they conduct electricity using a circuit and bulbs, what variable would you be changing?
Q.4.
If you were carrying out an investigation into the effect of light on seed germination, what would be the dependent variable?
Q.5.
You would like to investigate the effect of water resistance on different shapes molded from plasticine. You are dropping the shapes in a beaker of water. What is the dependent variable?
Q.6.
If you were carrying out an investigation into the effect of light on seed germination, which variable would you change?
Q.7.
If you investigated the effect of water resistance on different shapes molded from plasticine by dropping them in a beaker of water and timing how long it takes them to reach the bottom, what would happen if you changed the amount of water, the shape of the plasticine and the mass of the different shapes?
Q.8.
What unit of measurement would you use to record the amount of time it takes different shapes to reach the bottom of a beaker of water?
Q.9.
You are testing materials to see whether they conduct electricity. You have built a circuit of a battery and two crocodile leads which you will attach to the material. What is missing?
Q.10.
If you were carrying out an investigation into the effect of light on seed germination, how would you measure the dependent variable?
