Salty Pits
Source Institutions
In this activity, learners explore how different deodorants work. Learners treat agar plates with different types of deodorants and compare the bacteria growth on the plates to the control sample.

Single-Cell Life
Source Institutions
In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

Easy PEAsy Seed Germination
Source Institutions
In this activity, learners determine the necessary conditions for pea seed germination.

Gravestone Weathering
Source Institutions
In this activity (located on pages 9-14 of PDF), learners visit a cemetery to examine the distinguishing characteristics of rock weathering.

Chemistry in the Kitchen
Source Institutions
In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the

CD Greenhouse
Source Institutions
In this activity, learners plant seeds and watch them sprout and grow inside a CD case.

Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

DNA Fingerprinting
Source Institutions
In this forensics activity, learners solve a mystery using “DNA” taken from the scene of the crime.
The Water (Hydrologic) Cycle: Transpiration
Source Institutions
In this lab, learners grow broad bean (also called fava bean) plants in three EarthBoxes for a few weeks before exposing one to wind (using a fan), another to heat (using a lamp), and the third to not

Lighting Up Celery Stalks
Source Institutions
In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

Take a Plant to Lunch
Source Institutions
Learners make a "menu" of any plants in their lunch for Monday through Friday and draw the plants from their lunch.

Mermaid's Purse
Source Institutions
In this activity (page 2 of pdf), learners craft a model of a skate egg case and come to understand that cartilaginous fish such as sharks and shakes employ reproductive strategies that differ from th

Living Clocks
Source Institutions
In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

Traveling Nanoparticles Model
Source Institutions
This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

Diffusion of Water with Gummy Bears
Source Institutions
In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

Using a Sundial
Source Institutions
In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

Styrofoam Traps
Source Institutions
In this activity, learners use Styrofoam to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

Comparing Crystals
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

Running on Empty
Source Institutions
In this exercise and nutrition activity, learners will explore how food is the fuel that powers them. They will create a chart to figure out how many calories they burn during recess.
