Week #8: Magnets
- Recognize that magnets are used for devices in your home
- Predict if a material is attracted to magnets
- Test and sort materials based on if they are attracted to magnets
- Demonstrate the polarity of magnets
- Construct a device that uses magnets
- Demonstrate that magnetic force acts at a distance and through obstacles
- Record and share observations
- Learners examined devices and toys that used magnets to work.
- Learners sorted materials based on their predictions of if a material would be attracted to a magnet or not. They then tested the materials and recorded their observations.
- Learners observed how far away an object could be from different magnets and still be pulled towards the magnets.
- Learners constructed a simple roller car designed to be pushed by magnetic forces.
Questions to Discuss
- What is one tool or device that uses magnets?
- What is one clue that might help you guess if a material might be attracted to a magnet?
- Why would some coins be attracted to a magnet but others were not?
- What do you observe when two magnets are brought close together?
- Why was it important to keep your car as light as possible to be moved by your magnet?
Things to Try at Home
- With the help of an adult, search for five or more magnets that are part of machines and objects in your house. Keep track of what you find using a word list or pictures to share.
- What are some symbols that you use to help sort things around your house? Hint: some might be a symbol that tells you if a quality or ingredient is present, others will be a warning.
- Search for examples of jobs being done with super big magnets. Make a poster or a picture collage to share what you find about these super big magnets. How do they make life better or easier?
