Steps
Review the background information on Gravity before starting.
Build an electromagnet by wrapping insulated wire around a nail and connecting it to a battery. Test how many paper clips it can pick up. Try adding more wire coils.
Draw a detailed diagram of what you observe.
Write a conclusion: what did your results show? Did they match your prediction?
