What Color is Your Air Today?
Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

Diatom Ooze: Ooze Clues
Source Institutions
In this activity, learners will plot the distribution of various oozes using information from sediment maps.

Earthquake-Proof Buildings
Source Institutions
In this geology and engineering activity (page 7 of the PDF), learners build an earthquake simulator, then use it to test various building designs, exploring different materials, shapes, and design op

Classroom Dinosaur Dig
Source Institutions
In this activity, learners participate in a simulated dig to discover fossilized dinosaur bones. Learners take notes, make a map and propose theories about dinosaurs.

Using a Simple Astrolabe
Source Institutions
In this activity, learners use an astrolabe to measure the altitude of objects. Learners will first practice taking measurements by measuring the altitude of trees and buildings.
Flesh Out a Fossil
Source Institutions
In this activity, learners discover how artists start with a skeleton and turn it into a realistic drawing of a dinosaur.

Got Seaweed?
Source Institutions
In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

Edible Soil
Source Institutions
In this yummy activity about soil (page 9 of PDF), learners will create layers of soil using food. They will learn about the composition and role of each layer.

It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

How Animals Stay Warm
Source Institutions
In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

Paper Cup Anemometer
Source Institutions
In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

Conductivity: Salty Water
Source Institutions
Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

Why do Raindrops Sometimes Land Gently and Sometimes Land with a Splat?
Source Institutions
In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

A Crayon Rock Cycle- Metamorphic
Source Institutions
This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

Exploring Moisture on the Outside of a Cold Cup
Source Institutions
In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

Light is Made of Colors
Source Institutions
Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
