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.
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.
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.
Whose Fault Is It?
Source Institutions
In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.
Graph Dance
Source Institutions
In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.
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.
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.
Scaling Cubes
Source Institutions
In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.
Having a Gas with Cola
Source Institutions
In this activity, learners measure the amount of carbon dioxide in a carbonated drink.
Pi Graph
Source Institutions
In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.
Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.
Evolution in Plane Sight
Source Institutions
In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.
Earth Walk
Source Institutions
In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook
Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.
Radioactive-Decay Model: Substitute coins for radiation
Source Institutions
Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.
Cylinders and Scale
Source Institutions
In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.
Burn a Peanut
Source Institutions
In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.
Fast Rusting
Source Institutions
In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.
