CONVERSEMOS: ¿Qué cosa interesante podrías hacer usando imanes?

Hay tantas posibilidades. Esta es una que me gusta: la barredora magnética que utilicé en el estacionamiento para recoger clavos y objetos afilados para que no perforaran las llantas de mi carro.

In this lesson, students will explore the surprising properties of magnets and experiment with an invisible force that acts at a distance. In the activity, Magnet Discovery, students use ring magnets and common objects to discover the push and pull of magnets and how magnets attract certain types of metals.

Prep Instructions

Set Up Magnet Test Items

The test items should include some metals that are attracted to magnets, some metals that are not, and some non-metal items. At a minimum, students should examine one item from each of these categories. You may want to set up a test item station so that students can explore multiple items from each category.

Cut Up String

Before class, cut up the string so that each student can have some for their experiments.

Teacher Tip

Magnets are fragile, so be careful. If you smack them against each other too hard, they will break. We trust you’ll be gentle with them, but just in case, it can’t hurt to wear safety goggles.
