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. He put soil, food, and worms in a clear jar. He placed a shoebox with holes in it and then put the jar in it. The lid was kept on the shoebox, except when Jim was making an observation. IF Jim does this experiment correctly, what will he do each time he takes the lid off the shoe box?
What is collect and record data (what does Jim see) ?
