Comparing Sizes of Microorganisms
Source Institutions
In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.

Size, Scale and Models
Source Institutions
In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

Breaking Point
Source Institutions
In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

TerrAqua Investigation Column: What is the Land-Water Connection?
Source Institutions
In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

Ripening of Fruits and Vegetables
Source Institutions
In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

Slowing the Flow
Source Institutions
In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

Kimchee Fermentation Chamber
Source Institutions
Learners make kimchee or sauerkraut, which is really just fermented cabbage, in a 2-liter plastic bottle.

Can You "See" Thermal Radiation?
Source Institutions
Use this hands-on activity to demonstrate infrared and thermal radiation.

Carbon Sequestration
Source Institutions
In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

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.

Our Sense of Sight: Eye Anatomy and Function
Source Institutions
In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

Energy For Life
Source Institutions
In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

Bury Me Not!
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

Human Impact on Estuaries: A Terrible Spill in Grand Bay
Source Institutions
In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.
