A Crayon Rock Cycle - Igneous
Source Institutions
This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

Glitter Slime
Source Institutions
In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

Airboat
Source Institutions
In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

How Do We Find Planets Around Other Stars?
Source Institutions
This fun and simple hands-on astronomy activity describes techniques scientists use to find planets orbiting other stars.

Seafood Surgery
Source Institutions
In this hands-on activity, learners discover the similarities and differences between a vertebrate and invertebrate by dissecting a perch and a crawfish.

The Beaks of the Finches
Source Institutions
In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.

Volume, Mass, and Density Boxes
Source Institutions
This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

Mystery Box: Making Observations and Collecting Data
Source Institutions
This activity was designed for blind learners, but all types of learners can use it to learn to differentiate between qualitative and quantitative observations and to practice data collection.

Liquid Crystal Thermometers
Source Institutions
In this activity, learners explore liquid crystal thermometers to observe how heat flows by conduction, convection, radiation, and evaporation.

FlyBy Math: Distance-Rate-Time Problems in Air Traffic Control
Source Institutions
In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

Doppler Effect
Source Institutions
In this activity, learners use a tuning fork to explore how the Doppler effect works.

Chromatography
Source Institutions
In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

Strange Attractor: Observe Chaotic Motion
Source Institutions
In this activity, learners can observe chaotic motion. A magnet tied to a piece of string makes a pendulum, which swings over three sets of fixed magnets.

Chocolate Lava
Source Institutions
In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

Reaction: Yes or No?
Source Institutions
In this activity, learners mix ingredients in a plastic bag, and then identify three characteristics of a chemical reaction: production of heat, color change, and production of a gas.
Sodium Acetate Hand Warmers
Source Institutions
In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.

Cook with a Solar Oven
Source Institutions
In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

What Does Spit Do?
Source Institutions
Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

Lotus Leaf Effect
Source Institutions
This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.
