Junk-in-the-Box
Source Institutions
In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.
Bag of Bones
Source Institutions
In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.
Keep Out!
Source Institutions
In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.
Kick Stick Challenge
Source Institutions
In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across
Forces at the Nanoscale: Nano Properties of Everyday Plants
Source Institutions
This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.
Burst a Bubble
Source Institutions
In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.
Extreme Kicking Machine
Source Institutions
In this design challenge activity follow up to "Kicking Machine", learners add a hands-free feature to their Kicking Machine.
Motorized Car
Source Institutions
In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.
The Crayon Rock Cycle
Source Institutions
In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.
Grab and Go
Source Institutions
In this engineering activity, learners design and build a mechanical arm to lift a small item.
Soccer Kicks
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.
A Hurricane's Storm Surge Affects our Estuaries
Source Institutions
In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.
Kicking Machine
Source Institutions
In this design challenge activity, learners build a machine that kicks a Ping-Pong ball into a cup lying on its side 12 inches away.
Finding Fossils
Source Institutions
This activity (located on page 4 of the PDF under GPS: Baby Dinosaurs Activity) is a full inquiry investigation to determine the age of fossils based on where they are discovered.
Hot Spoons
Source Institutions
In this physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.
Jitterbugs
Source Institutions
In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.
Skewers and Garden Poles
Source Institutions
In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
Tasty Visions
Source Institutions
In this activity (5th activity on the page), learners explore how what you see influences taste. In experiment 1, learners taste five sodas, one of which is clear soda with orange food coloring.
Minibot
Source Institutions
In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
No-Slip Grip
Source Institutions
In this physical sciences activity, learners explore friction. Learners investigate the factors that affect the force required to move an object.
