Questions answered in science journal notebook
After researching this topic, you should be able to describe what a magnet is and some properties of magnets. You should also be able to describe objects that both attract and repel magnets.
You will get into groups of three and come to an investigation box. Each item is labeled with a number, your job is to predict whether or not the object will be attracted to a magnet or not. Record your results on an observation sheet your can obtain from your teacher.
