This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity, learners map their world by drawing a plan of their bedroom.

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
