Percentage of Oxygen in the Air
Source Institutions
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.
Hexagon Hunt
Source Institutions
This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.
Recycle Your Own Paper!
Source Institutions
In this activity (page 2 of PDF under GPS: Garbology Activity), learners will prepare sheets of homemade recycled paper from several different source pulps.
Ship the Chip
Source Institutions
In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.
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.
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
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.
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
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.
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.
Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.
Properties of Dust
Source Institutions
In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.
