Home Mycology Lab
Source Institutions
Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.

The Self-Watering Terrarium
Source Institutions
In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

Water Quality and pH Levels in Aquatic Ecosystems
Source Institutions
In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

Feed the Birds
Source Institutions
Learners construct a bird feeder from re-used materials. After hanging their feeder, they keep a journal about what birds visit the feeder.

Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
Sock Garden
Source Institutions
In this activity (located in the middle of the page), learners start a garden by planting their socks!

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

Seeds: Roots and Shoots
Source Institutions
In this indepth hands-on activity, learners build a structure that allows them to observe the growth of roots and the correlation between root growth and stem extension.
Butterflies in Space
Source Institutions
The Butterflies in Space Teacher's Guide uses "life in space" to encourage learners to conduct their own open-ended scientific investigations.

Homemade Rain Gauge
Source Institutions
In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.

Good Stress
Source Institutions
In this activity about physical stress (page 28 of PDF), learners discover that muscles and bones need to work to stay strong.

2-Liter Landfill
Source Institutions
In this activity, learners gain a better understanding of how household/school waste breaks down in a landfill. Learners collect trash and then create miniature landfills in 2-liter bottles.

Crew Strength Training
Source Institutions
In this activity, learners will train to develop upper and lower body strength in their muscles and bones by performing body-weight squats and push-ups.

Waves and Tides
Source Institutions
In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

Mosquito Life Cycle
Source Institutions
In this activity, learners build a plastic emergence chamber (or use purchased "mini mosquito breeder") to observe and analyze the mosquito life cycle.

Do a Spacewalk!
Source Institutions
In this activity, learners train to increase muscular strength and improve upper and lower body coordination by performing the “bear crawl” and the "crab walk.” Learners perform the exercises over tim

Bird Feeder
Source Institutions
In this outdoor activity, learners construct bird feeders and set them up at to investigate bird behavior for one or two weeks. Multiple feeder designs are suggested.

Photosynthesis and Transpiration
Source Institutions
In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

Base Station Walk-Back
Source Institutions
In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

Growing Plants
Source Institutions
In this "Sid the Science Kid" activity from Episode 107: My Shrinking Shoes, learners observe how plants change as they grow.
