Effects of Solar Radiation on Land and Sea
Source Institutions
In this activity, learners explore the different heating properties of soil and water.
Handy Measuring Ratio
Source Institutions
In this activity, learners use their hands as tools for indirect measurement.
Stride Ruler
Source Institutions
In this activity, learners use their feet to estimate distances. Learners calculate the distance of one step in centimeters by measuring 10 steps at a time to reduce measurement error.
Mega Bounce
Source Institutions
In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.
Counting With Quadrants
Source Institutions
Millions of organisms can live in and around a body of water.
The Shadow Knows I
Source Institutions
In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.
Super Bounce
Source Institutions
In this activity (on page 1 of the PDF under SciGirls Activity: Soccer Ball Kick), learners will investigate the transfer of energy using sports equipment.
Take It in Stride
Source Institutions
In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.
Experiencing Parallax With Your Thumb
Source Institutions
In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.
Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.
Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.
Equatorial Sundial
Source Institutions
In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.
Is It Possible: Estimating Measurement
Source Institutions
In this activity, learners will decide together on a question about how far, long or high the group could reach together.
Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.
Base Station Walk-Back
Source Institutions
In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.
Playground Patterns of Cracks
Source Institutions
In this math activity, learners observe and sketch cracking patterns in pavement.
It's the "Rain," Man
Source Institutions
In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.
The Size and Distance of the Planets
Source Institutions
In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.
What Causes Pressure?
Source Institutions
In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.
Finding the Size of the Sun and Moon
Source Institutions
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.
