IOOS K-12 Toolkit
Cool Playgrounds
Outdoors on a sunny, warm day, students explore how areas in the shade and light colors remain a bit cooler than areas in the sunshine and dark colors. Then they apply what they’ve learned to design a shade structure that will keep a playground cooler during hot summer days.
Colors of Snow
Students learn that snow can be various shades but is usually light in color, which reflects most of the sunlight that hits it, unlike darker materials.
Snowflake Shapes
Learn how snowflakes form and about their unique patterns, and then use images of real snowflakes to create your own snowflake model.

Keeping Warm
Students learn how people and wildlife keep warm during cold winter weather.
Sunshine and Shadows
Students explore how shadows work and why they change through the day as the Sun appears to move across the sky by comparing their shadows at different times of the day and modeling with shadow puppets to see how the location of a light source changes a shadow.
