Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

Learners construct a bird feeder from re-used materials. After hanging their feeder, they keep a journal about what birds visit the feeder.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this activity, learners use an astrolabe to measure the altitude of objects. Learners will first practice taking measurements by measuring the altitude of trees and buildings.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

In this activity about physical stress (page 28 of PDF), learners discover that muscles and bones need to work to stay strong.
