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.
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.
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.
Linear Functions: Mystery Liquids
Source Institutions
In this math lesson, learners analyze the density of liquids in order to explore linear functions.
Polynomial and Rational Functions: Building Boxes
Source Institutions
In this math lesson, learners explore polynomial and rational function patterns.
What Shape Is It?
Source Institutions
In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.
A Cubic Foot Per Second
Source Institutions
In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.
Forgotten Genius
Source Institutions
This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p
Five-Layer Density Column
Source Institutions
In this activity, learners can create five-layer density columns by employing one of three (or all) methods.
How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.
Insulation Station
Source Institutions
In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.
