- To encourage discovery of basic scientific concepts
Before You Start: Gather the following materials: uncooked white rice, a tennis ball can (with label peeled off), crafting glue, magnetic wand, pom-poms, magnetic marbles, pipe cleaners, rhinestones, beads, colored wood cubes, foam shapes, jingle bells, paper clips and coins. Tip: have items on hand that both attract and repel magnets. After you have gathered all of the items, lay them out on a large table.
Let's Get Started! Step 1. Have children help you select and place some of the following items into the tennis ball can (about 15-20 different pieces): pom-poms, pipe cleaners, magnetic marbles, rhinestones, beads, colored wood cubes, foam shapes, jingle bells, paper clips, coins etc.
Step 2. Fill the tennis ball can almost to the top, and pour the white rice inside the can, covering all of the items. Leave about 1" of space between the rice and the top of the can. (Tip: make sure the items you put into the can are brightly colored, so they show up in the rice.)
Step 3. Line the inside of the lid with glue and place the lid back onto the tennis ball can, sealing the items and rice inside.
Step 4. Have children take turns using the wand to run over the outside of the tennis ball can to see what attracts and repels the magnets. Take this opportunity to go into depth about magnetic properties.
Furthermore: Discuss further what items attract versus repel the magnets. Ask the kids to name other items around your center that they think might be magnetic and ones that are not, based on their observations of this activity. To further reinforce this lesson, consider using magnetic discovery boards and kits.
