🔬 4th grade Science: how to help at home

What each unit covers

1. 🦇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.

2. 💡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.

3. 🔊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.

4. 🔋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.

5. 🦊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).

6. 🎳Energy, Speed & Collisions

   Practices how an object's speed relates to its energy, what happens to energy when objects collide, and devices that change energy from one form to another.

7. 📡Waves & Codes

   Practices how waves have amplitude and wavelength and can make objects move, and how patterns like codes, flashes and digital signals carry information.

8. 🏜️Rock Layers & Erosion

   Practices how water, ice, wind and plants break down and move rock, and how patterns in rock layers and fossils show how a landscape changed over time.

9. 🌋Oregon Volcanoes, Quakes & Maps

   Practices reading maps of mountains, volcanoes, earthquakes and ocean features to find patterns, and comparing solutions that reduce harm from earthquakes, eruptions, landslides and tsunamis, using Oregon's Cascade volcanoes, Crater Lake and the Cascadia Subduction Zone.

10. ⚡Oregon Energy Resources

    Practices how energy and fuels come from natural resources like moving water, wind, sunlight, Earth's heat, coal, oil and gas, and how using them affects the environment, with Oregon examples like Bonneville Dam on the Columbia River, wind turbines east of the Cascades and geothermal heat in Klamath Falls.
