Watching Crystals Grow
Source Institutions
Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.
Composite Materials
Source Institutions
This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.
Do Your Own Dig
Source Institutions
In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.
Homemade Hovercraft!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.
Wild Sourdough
Source Institutions
In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.
Transformation of E. coli Using Green Fluorescent Protein
Source Institutions
In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.
Handwashing Laboratory Activities: Bowl Technique
Source Institutions
In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.
Design and Build a Barometer
Source Institutions
In this activity, learners make a barometer, an instrument to measure change in air pressure.
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.
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.
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.
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.
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.
Reason for the Seasons
Source Institutions
In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.
