The Decayed Pumpkin
Source Institutions
In this "Sid the Science Kid" activity from Episode 106: My Mushy Banana, learners explore the effects of decay by comparing and contrasting something (an old pumpkin) that's decayed with the same thi
Stack-o-Pennies Shop
Source Institutions
In this math activity, learners pretend there is a special store that lets you pay for toys by their height in pennies.
Think Fast!: Just How Quick Are You?
Source Institutions
This is an activity about reaction times. Just how quickly must an NHL goalie respond to save a shot, and how does your reaction time compare?
Puff Mobile
Source Institutions
In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.
Take a Guess
Source Institutions
In this activity, learners use what they know about probability to figure out what is in a mystery bag. Learners analyze data to guess how many of each color crayons are in the bag.
Program a Friend
Source Institutions
In this activity (on page 2), one person "programs" the other like a robot to move through a space, trying to get them to avoid obstacles and reach a goal.
How Many Pennies?
Source Institutions
In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.
Watercraft
Source Institutions
In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.
Crystal Packin' Mama
Source Institutions
In this activity, learners investigate the basic crystal structures that metal atoms form.
Go with the Flow
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.
What is Energy?
Source Institutions
In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.
Modeling Tidal Action
Source Institutions
In this activity (Lesson 1), learners work in groups to create tide simulations.
Three Colors of Light
Source Institutions
Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.
¡Terrario!
Source Institutions
En esta actividad, los aprendices harán un terrario usando materiales simples.
Make a Friend from Soil and Seeds
Source Institutions
Learners assemble a figure from a nylon stocking or sock stuffed with soil and seeds. The ends of the nylons inside the jar absorb water, which feeds the grass seeds.
Magnetic Lines of Force
Source Institutions
With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.
High Rise
Source Institutions
In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.
Composites
Source Institutions
In this activity, learners explore how composites work by creating and testing their own composite for an imaginary company.
Fish Eyes: More than Meets the Eye
Source Institutions
In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.
Going Green
Source Institutions
In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.
