Activities Using Household Materials

• Go Bug! (K - 3rd) - Ever played the card game Go Fish? If you know the rules, you can easily learn how insects undergo the stages of metamorphosis to become an adult.

• Earth’s Water: A Drop in Your Cup (3rd - 5th) - Our planet's surface may be mostly covered in water, but how much of that can we use? In this activity, students will see how water is distributed across different sources and how much can be used by humans.

• Worlds in Comparison (2nd - 6th) - Do you know the relative sizes of the planets in our solar system? Put yourself to the test with some Play-doh! This activity allows students to model, in three dimensions, the relative sizes of the planets.

• Build a Coral Polyp (2nd - 6th) - By building an edible coral polyp, students will learn the anatomy of coral and be able to explain why corals are animals, rather than plants.

Explanation of the immune system and white blood cells

Also covers a lot more information about keeping our bodies healthy

• skin

• lymphatic sytem

• and so much more...

Two experiments to be done at home. Instructions are in both English and Spanish

• Water-Energy Nexus Lesson - Explore the relationship between water and energy (water-energy nexus) and build a model to demonstrate the way water travels from sources to homes and businesses.

• Nexo Agua-Energía - Explorar la relación entre el agua y la energía (nexo agua-energía) y construir un modelo para demostrar la forma en que el agua viaja desde las fuentes hasta los hogares y las empresas.

• Electromagnetic Forces *Lesson should be completed with adult supervision* - Explore magnetism and design electromagnets to explain the phenomenon: when an electric current moves through a wire, an invisible magnetic force surrounds the wire. Adding a nail to the electromagnet will temporarily magnetize the nail.

• Fuerzas Electromagneticas *La lección debe completarse con la supervisión de un adulto* - Explorar el magnetismo y diseñar un electroimán para explicar el fenómeno: cuando una corriente eléctrica se mueve a través de un cable, una fuerza magnética invisible rodea el cable. Agregar un clavo al electroimán magnetizará temporalmente el clavo.
