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 make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.

Historically, sea floor mapping (bathymetry) was done by soundings.

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

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

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

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
