Full of Hot Air: Hot Air Balloon Building
Source Institutions
In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.
Clam Hooping
Source Institutions
In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.
Plankton Feeding
Source Institutions
This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.
Constellation Chamber
Source Institutions
Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.
Simple Machine Challenge
Source Institutions
In this activity, learners are challenged, using everyday objects, to create simple machines to complete specific tasks.
Edible Glass
Source Institutions
In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.
Wetland Bioblitz
Source Institutions
This activity (located on page 3 of the PDF under GPS: Temperate Rain Forest Activity) is a full inquiry investigation into biodiversity of a given habitat.
More Bubbles!
Source Institutions
In this math activity, learners make their own bubble wands and determine if the size of the wand affects the number of bubbles it produces.
Clipbirds
Source Institutions
In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.
In Proportion
Source Institutions
Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.
Design and Build a Better Candy Bag
Source Institutions
In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.
The Web of Life
Source Institutions
In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.
Sand Grain Observations
Source Institutions
In this activity (on page 1 of the PDF under SciGirls Activity: Earthquakes), learners will use a magnifier to carefully examine samples of sand from different locations.
Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.
Tree Tally
Source Institutions
In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.
Periscope
Source Institutions
In this activity, learners construct a device that allows them to look over ledges or around corners.
Plant Piping
Source Institutions
Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.
Block Neighborhood
Source Institutions
In this activity learners will build a neighborhood out of blocks and cardboard.
