Magnetic strength is different than the strength of a person who can lift a lot of weight or a material that can't break, like wood. Third graders are investigating how to find the strength of a magnet and they did so by asking some really great questions first!
Which magnet is the strongest?
Which magnet has the biggest magnetic force?
Do bigger magnets mean more force?
Finding Magnetic Strength!
With limited materials, third graders planned and carried out an investigation to determine which magnet was the strongest. They had to collect data in a data table, graph it, and use the data to provide evidence and reasoning to support their claims. Way to go third graders!
