The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.
Meteoroids and the Craters They Make
Source Institutions
In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.
Where Will It Go?
Source Institutions
In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.
The Shape of Floatation
Source Institutions
In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.
Lifting with Levers!
Source Institutions
In this fun hands-on activity learners explore a simple machine: the lever. What happens to a load when you multiply the length of a lever? Find out here!
Measuring Your Breathing Frequency at Rest
Source Institutions
In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.
Watch It Fly
Source Institutions
Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.
Ramps 1: Let it Roll!
Source Institutions
In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.
Building Tetrahedral Kites
Source Institutions
Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.
Best Bubbles
Source Institutions
In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.
Statistics: Wet Heads
Source Institutions
In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.
Charge Challenge
Source Institutions
In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.
Making a One-Second Timer
Source Institutions
This lab activity has learners create a pendulum with a one-second period.
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).
Incredible Shrinking Shapes
Source Institutions
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.
Modeling Limits to Cell Size
Source Institutions
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
Plot the Dot: A Graphical Approach to Density
Source Institutions
In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.
Sublime Sublimation
Source Institutions
In this activity, learners explore sublimation by conducting experiments with dry ice.
Measure the Speed of a Water Leak
Source Institutions
In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.
Canine House of Cards
Source Institutions
This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.
