Variation Game
Source Institutions
In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.
Tabletop Biosphere
Source Institutions
In this activity, learners create a sealed, mini ecosystem that supplies freshwater shrimp with food, oxygen, and waste processing for at least three months.
Testing for Life's Molecules
Source Institutions
In this activity, learners conduct tests for proteins, glucose, and starch.
DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
Forensic Science: Hair Sample Investigation
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.
Pickle-oh!: Musical Pickle Instrument
Source Institutions
What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.
Mirrorly a Window
Source Institutions
In this activity about light and reflection, learners discover that what you see is often affected by what you expect to see.
Clap Sensor: Build a Sound Sensor Using a Pico Cricket
Source Institutions
This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.
Crayfish Investigations
Source Institutions
This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
Shake and Make: Charge Recognition
Source Institutions
In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.
DNA Jewelry Models
Source Institutions
In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.
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.
Colorful Electrophoresis
Source Institutions
In this activity, learners follow step-by-step instructions to build a gel electrophoresis chamber using inexpensive materials from local hardware and electronic stores.
Seas in Motion
Source Institutions
In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.
What Do You Know About Microbes?
Source Institutions
This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.
Plankton Races
Source Institutions
In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.
Science Cooks!
Source Institutions
In this health, cooking, and math activity, learners explore nutrition and examine nutrition labels.
Disease Detectives
Source Institutions
In this activity, learners examine antibodies and antibody recognition using a model.
Slimy Cells
Source Institutions
In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.
