Gene Switches
Source Institutions
In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.
Not Just A Bag Of Beans
Source Institutions
In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.
Magnifying and Observing Cells
Source Institutions
In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.
A Simply Fruity DNA Extraction
Source Institutions
In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.
The Sharp Eyes of a Naturalist
Source Institutions
In this creative activity, learners will practice looking carefully to observe details and to become familiar with dioramas as a method for displaying naturalistic scenes.
West Coast Shipwrecks
Source Institutions
In this data activity, learners will explore shipwrecks from four National Marine Sanctuaries on the West Coast of the United States.
Shoebox Dinosaur Dig Site
Source Institutions
In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.
Free-living and Plant-Parasitic Nematodes (Roundworms)
Source Institutions
This lesson introduces learners to the world of nematodes (roundworms).
Rotational Equilibrium
Source Institutions
In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.
Motorized Balancing Toy
Source Institutions
In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.
Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.
Buoyancy Bulls-Eye
Source Institutions
In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ
Tobacco Mosaic Virus
Source Institutions
In this four-part laboratory exercise, learners investigate properties of Tobacco mosaic virus (TMV) including (1) symptoms induced by the virus in susceptible plants at the macroscopic and microscopi
Life Size: Line 'em up!
Source Institutions
In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.
It's All About Birds
Source Institutions
In this activity, learners create their own bird species using arts and crafts materials. The bird call recordings are not online so the introduction activity can't be done, but everything else can.
Close, Closer, Closest
Source Institutions
In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.
Mold Mole Molds
Source Institutions
In this activity, learners make different shapes that hold exactly one mole of gas (air).
Plenty on the Plains
Source Institutions
In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent
Submarine: Lift Bag Lander
Source Institutions
In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.
A Book About Me
Source Institutions
In this math activity, each learner creates a book about themselves using a template. Learners discuss the different parts of the body and practice measuring their body parts using crayons.
