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.
Critical Load
Source Institutions
In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.
Finger Basketball
Source Institutions
In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.
Twirling in the Breeze
Source Institutions
In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.
Relative Speed of Dinosaurs
Source Institutions
In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.
Jiggly Jupiter
Source Institutions
In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.
Can Energy be Created or Destroyed?
Source Institutions
In this activity, learners explore conservation of energy by experimenting with a solar cell light device.
Zip Line Zoo
Source Institutions
In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.
Mold Mole Molds
Source Institutions
In this activity, learners make different shapes that hold exactly one mole of gas (air).
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?
The Pull of the Planets
Source Institutions
In this activity, learners model the gravitational fields of planets on a flexible surface.
Ripening of Fruits and Vegetables
Source Institutions
In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.
Bend a Carrot
Source Institutions
In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.
Going Green
Source Institutions
In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.
Greeting Card Boxes
Source Institutions
In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.
Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).
Can You "See" Thermal Radiation?
Source Institutions
Use this hands-on activity to demonstrate infrared and thermal radiation.
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.
What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
