Trash Talkin'
In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.
Let's Make Molecules
Source Institutions
In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).
Build a Fruit Fly Trap
Source Institutions
In this construction activity, students use a 2-liter bottle to build a fly trap.
Breaking Point
Source Institutions
In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.
Seedy Travelers
Source Institutions
In this activity (on pages 18-28), learners explore how the shape of seeds affects how they are dispersed by wind, birds, ocean currents and other means.
Tree Investigations
Source Institutions
In this activities, learners head outside and investigate trees through bark rubbings. Learners will need paper, a pencil, and some unwrapped crayons to create them.
Design a Park
Source Institutions
In this activity, learners are invited to imagine the park of their dreams!
OBIS Oil Spill
Source Institutions
In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.
Nano Scavenger Hunt
Source Institutions
This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.
Moving Without Wheels
In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.
Elephant Foot
Source Institutions
Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.
Hot Stuff!: Carbon Dioxide Extinguishes a Flame
In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.
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.
Food Webs
Source Institutions
In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.
Engineer A Bird Feeder
Source Institutions
In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.
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.
Echolocation in Action!
In this activity, learners simulate whale echolocation. Learners experience echolocation by wearing blindfolds, while another learner makes snapping noises in front of, behind, or to the side of them.
Shapes and Colors and Textures, Oh My!
Source Institutions
This is an activity about discovering the colors and beauty of nature. Learners will spend time outdoors, matching paint chip samples, colored paper, or colors of clothing to those found in nature.
Beach Finds Curiosity Cart
Source Institutions
In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.
