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.
Subtracta's Dog
Source Institutions
In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.
Big Sun, Small Moon
Source Institutions
Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.
Percentage of Oxygen in the Air
Source Institutions
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.
Pulse of Life: Measure Your Pulse
Source Institutions
In this activity, learners take their own pulse and explore how heart rate is affected by various activities.
Geometry and Spatial Relations: Mirror, Mirror
Source Institutions
In this math lesson, learners use hinged mirrors to discover that regular polygons are composed of triangles tessellating around a center point.
Using Food Labels
Source Institutions
In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.
Pocket Solar System: Make a Scale Model
Source Institutions
This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.
The Ups and Downs of Body Temperature
Source Institutions
In this activity (1st on the page), learners explore circadian rhythms by keeping track of their body temperature.
Our Solar System to Scale
Source Institutions
In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.
Drinking Straw Pulse Measurer
Source Institutions
In this health activity, learners create a device so that they not only feel their heartbeat, but also see it, using a straw and some clay.
Special Effects: Titanic and Beyond
Source Institutions
In this activity, learners investigate how geometry plays a role in perspective.
Test the Finger Wrinkle Hypothesis
Source Institutions
Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?
Investigating Density Currents
Source Institutions
In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).
Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.
Heart and Lungs
Source Institutions
In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.
Shadow Play
Source Institutions
In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.
Building Houses: Build a Cardboard Tube House
Source Institutions
Build a house you can fit inside, using cardboard tubes.
Size it Up
Source Institutions
Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.
