Isopods
Source Institutions
In this outdoor activity, learners dig for and collect isopods (sometimes known as "roly-poly bugs" or "potato bugs" and other names).
Insect Collection
Source Institutions
Learners use several types of insect sampling and collection equipment to make an insect collection. Learners can collect insects from their schoolyard or yard at home.
Pesticides and Eggshell Thinning
Source Institutions
This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.
Our Sense of Hearing
Source Institutions
In this activity, learners investigate the sense of hearing and plan and conduct their own experiments.
Thymus DNA Extractions
Source Institutions
This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.
Mussel Your Way Through Photosynthesis
Source Institutions
Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.
Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.
Carbon Dioxide Removal
Source Institutions
In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.
Bird Beak Buffet
Source Institutions
In this classic activity, learners investigate natural selection by becoming birds foraging for food on an island.
Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
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.
Colorblind Dogs
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Colorblind Dogs) is a full inquiry investigation into dogs' ability (or inability) to see color.
Doghouse Design
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.
Examining the Heart
Source Institutions
In this activity about the heart (on page 22 of the PDF), learners examine sheep or chicken hearts to learn about the heart's structure and the flow of blood through the heart.
Salt Water Revival
Source Institutions
In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.
Illuminating Luminescence
Source Institutions
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
Clippy Island: An Investigation into Natural Selection
Source Institutions
In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L
Jay Play
Source Institutions
In this outdoor activity, learners find out the color of food that jays prefer and then try to change the birds' preference by altering the taste of the food with salt.
What Cells Can I See in Muscle and Spinal Cord Tissues?
Source Institutions
In this activity (page 37 of the PDF), learners observe, on a prepared slide, muscle and spinal cord cells from a rat.
Survival of the Fittest: Variations in the Clam Species Clamys sweetus
Source Institutions
This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi
