What this lesson teaches
This activity illustrates the properties of matter and magnetism. By combining glue and iron filings, children observe how a liquid can become solid-like and respond to magnetic forces.

This activity illustrates the properties of matter and magnetism. By combining glue and iron filings, children observe how a liquid can become solid-like and respond to magnetic forces.
The hands-on manipulation of slime engages students' tactile senses and visual observation, making abstract concepts of magnetism and states of matter more concrete. This aligns with Vygotsky's scaffolding principle, as children build understanding through direct interaction and observation.
1. In a bowl, mix 1 cup of white glue with 1/2 cup of water. 2. Stir in 1/4 cup of liquid starch until it thickens. 3. Add 2 tablespoons of iron filings and mix well until combined. 4. Knead the slime with your hands until it reaches a gooey consistency. 5. Use a magnet and bring it close to the slime — watch how it reacts! 6. Experiment by adding more iron filings or trying different magnets — what happens?
