Title - Magnetic attraction through objects
By - Scott Dan
Subject - Science
Grade Level - 1st - 2nd
Magnets: "Attraction through objects"
Materials:
1. Prediction / Observation worksheet
2. 24 doughnut shaped magnets
3. 12 small boxes each filled with the following:
a.) Iron fillings
b.) Magnetic wand
c.) Magnetic ball
d.) 2 ¾" magnetic button
4. Student desks
5. Student books
6. Sheet of plywood (not large)
7. 1 Tub a ware container (empty)
8. 1 Tub a ware container (filled with water)
9. Cardboard
10. Glass (a glass cup or sheet of glass will work)
11. Large chart paper and markers
Preparation:
1. Fill the small boxes with items from the list above: 3, a-d.
2. Make a chart like the one the children have but on a large chart paper
Procedure:
1. Hand out worksheet to children. Have them take out a pencil.
2. Ask them to make predictions if they think that a magnet will go through each of the items listed on the worksheet. Read them one at a time, showing them the item, as it is read, and ask them to draw a smiley face for yes and a frowning face for no in the blank. Explain that numbers 8 and 9 allow for them to choose an object in the room and test it out. Let them know that their answer is a prediction, or a guess. They do not receive a grade on this. It is what scientists do before they know an answer to something. It is by testing our predictions that we find out answers to many questions.
3. Break the children into groups of 2
4. Have each group then fill out the observation part of the worksheet by testing each one of the materials. Explain that seven items (plywood, containers, cardboard and glass) will be at particular locations (show them) and that they must share. If someone else is using it, then they must wait in line or do another object first and then get in line again.
5. When done, ask them to get a pencil box with several other times in it
6. Ask them to use these materials and see what they do when you try to attract these through the same objects
7. Allow 15 -20 minutes for exploration or adjust as needed.
8. Have the children meet back by the calendar area where the teacher has prepared a large piece of paper that looks like their paper. Ask for results and have students write a smiley face or frown face, depending on if the magnet would attract through the object. Discuss each object and ask why they think it did what it did. Discuss results of misc. items in pencil box. Discuss thickness, strength of magnet, and material of object, depending on the children's responses.
9. Ask for any questions. Let them know the next time we meet we are going to have problem solving games with magnets. Have them write in their journals about something they have learned about magnets.
