Exploring Materials: Liquid Crystals
Source Institutions
In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.
Bat Echolocation Experiment
Source Institutions
In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.
Separating with Chromatography
Source Institutions
In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").
Rate It: Working With Zero and Negative Numbers
Source Institutions
In this activity, learners will rate the day, a book, or something else on a scale from -2 to 2. This activity works well for groups of all ages.
Measuring Rules
Source Institutions
In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .
Smelly Balloons
Source Institutions
In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.
Pulse Pointer
Source Institutions
In this activity, learners investigate circulation and measure their own your heartbeat. A heart rate, or pulse, is the number of times the heart beats per minute.
Ask an Elder
Source Institutions
In this activity, learners listen to a story and tell a story of their own as they learn about the importance of elders in Native American cultures.
Fused Plastic Wallet
Source Institutions
In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.
Scream Cup
Source Institutions
In this activity, the learner will experiment with the physics of sound production while making a sound making toy. The activity includes a video with step by step instructions.
Design a Microexpression Zoetrope
Source Institutions
In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.
The Straw Flute
Source Institutions
In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.
In the Middle
Source Institutions
In this game-like activity (5th activity on the page), learners explore their auditory acuity as well as the importance of having two ears.
Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.
Color Draw
Source Institutions
In this activity, learners use their understanding of probability to guess which color will be drawn from a bag.
Amazing Marshmallows
Source Institutions
In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.
Sidewalk Constellations
Source Institutions
In this activity, learners will go outside and create a constellation.
What Goes Up...
Source Institutions
In this activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.
Gravity Fail
Source Institutions
In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.
Floating and Sinking Fruits and Veggies
Source Institutions
In this activity, learners will explore the density of an object in water. Learners will compare what happens to fruits and vegetables in regular and salt water.
