1. Jim was planting a garden and a friend suggested he put worms in his garden. Jim wanted to do an experiment to find out what worms do for gardens. Jim put soil, food, and worms in a clear jar. He placed a shoebox with holes cut in it on its side and put the jar in it. The lid was kept on the shoebox, except when Jim was making observations. If Jim does his experiment correctly, what will he do each time he takes the lid off the shoebox?

• 1. Add more worms to the jar.

• 1. Write down what he sees in the jar.

• 1. Try to guess where the worms will be.

• 1. Plan what he will do next in the experiment.

1. An equal amount of potting soil was placed in three identical pots. Twenty petunia seeds were used. Three seeds were planted in Pot A, seven seeds were planted in Pot B and ten seeds were planted in Pot C. All three pots were placed on the same table. After the plants grew to a height of 10 centimeters, they were cut off at soil level, dried overnight and weighed. The chart shows the average plant mass for each pot. What is the outcome (dependent) variable in this investigation?

• 1. The soil

• 1. The temperature

• 1. The plant mass

• 1. The space available for each seed

1. Why should scientists write down their experimental procedures?

• 1. So that the exact experiment can be repeated by others and the results compared.

• 1. So that the experiment can be changed by others to get different results.

• 1. So that the data will help people make decisions.

• 1. So that the data will prove their hypotheses correct.
