🔬 3rd grade Science: how to help at home

What each unit covers

1. 💡Light

   Natural and artificial light, things that make light and things that reflect it, shadows, transparent, translucent and opaque materials, mirrors, refraction, and how light technology affects people and wildlife.

2. 🔊Sound

   Vibrations and sound waves, pitch and volume, how sound travels through different materials but not through empty space, echoes and absorbing sound, how we hear, and how noise and sound devices affect people and animals.

3. 🦇Sense & Respond

   How people, animals and plants sense and respond to their environment: the nervous system, reflexes, special animal senses and plant responses to light, gravity and touch.

4. 🦊Adaptations & Habitats

   Practices habitats, body and behavior adaptations, camouflage, migration and hibernation, and how plants and animals rely on each other (pollination, seed dispersal, soil nutrients).

5. 🔋Energy on the Move

   Practices energy sources, how energy moves from a source to an object or living thing to cause action, and how people use their senses to detect heat, light and sound.

6. 🌻Energy from the Sun

   Practices how plants get the materials they need for growth mostly from air and water, and how the energy in animals' food was once energy from the sun.

7. 🐺Surviving in a Habitat

   Practices why some animals live in groups, how small differences in traits can help some individuals survive, and why some organisms do well in a habitat while others cannot survive there.

8. 🍄Matter Moves in Ecosystems

   Practices how matter moves among plants, animals, decomposers and the environment, with Pacific Northwest examples like salmon feeding forests after they spawn.
