From Polliwog to Frog
Source Institutions
In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.
As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
Dinosaur Homes
Source Institutions
In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.
My Insect
Source Institutions
In this activity, learners use information gathered from a variety of sources to design and make their own insect.
Make Your Own Butterfly
Source Institutions
In this activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.
Modeling the Night Sky
Source Institutions
In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.
Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.
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.
Vortex
Source Institutions
In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.
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.
Fruit Fly Trap
Source Institutions
Build a fruit fly trap out of a 2-liter plastic bottle and some rotten fruit! Fruit flies are easy to catch in warm weather. Once you catch some, you will be able to see their life cycle up-close.
The Watershed Connection
Source Institutions
In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.
Exploring Fabrication: Self-Assembly
Source Institutions
In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.
A Crayon Rock Cycle- Sedimentary
Source Institutions
This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.
Beach Buckets
Source Institutions
In this activity, learners explore a bucket of sand and beach objects.
