Physics Tug of War
Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.
Watch It Fly
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.
TopsAdd to list Details
In this activity, learners discover that some things only stand up while they are spinning.
Newton's Laws DemonstrationsAdd to list Details
In this collection of demonstrations, learners explore Newton's Laws of Motion.
Changing the Density of a Liquid: Adding SaltAdd to list Details
Learners see that a carrot slice sinks in fresh water and floats in saltwater.
The Pulse of Gravity
In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.
Comparing the Density of an Object to the Density of WaterAdd to list Details
Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.
Don't Crack Humpty
Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.
Defining DensityAdd to list Details
In this introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.
Changing the Density of an Object: Changing ShapeAdd to list Details
Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.
Plot the Dot: A Graphical Approach to DensityAdd to list Details
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.
In this demonstration, learners observe as a bottle is placed on a table with wooden hoop balanced on top and a pencil balanced on top of the hoop.
Heavyweight Champion: JupiterAdd to list Details
In this activity, learners confront their perceptions of gravity in the solar system.
Landing the Rover
In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).
Creepy CrawlersAdd to list Details
Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.
The Pull of the PlanetsAdd to list Details
In this activity, learners model the gravitational fields of planets on a flexible surface.
Linear Functions: Mystery Liquids
In this math lesson, learners analyze the density of liquids in order to explore linear functions.
Dunking the PlanetsAdd to list Details
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
The Liquid Rainbow
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Pre-School Ball Run!
In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.
