3rd Grade 3rd nine weeks Unit of Study - Rapid Changes

Dear 3rd Grade Families,

Our Focus

In this 3rd grade science unit we will learn about cause and effect relationships found in nature. This will includes investigating rapid changes such as: volcanic eruptions, earthquakes, and landslides.

Instructional Approach

We will be researching each rapid change through the internet and our school library. We will make models and collect observations using photographs. This will enhance your child’s understanding of our Earth’s surface and the changes that occur to it because of these rapid events.

Family Support

You can help your child in several ways.

  • Point out different landforms such as mountains, rivers, and valleys.
  • Ask questions about their origination. ( mountains could be formed from earthquakes/ sliding of plates )
  • Ask your child to show you how an earthquake, volcano, or landslide could affect the land around them.
  • Create your own models at home of each of the rapid changes!

Sincerely,

Donna Mullins
