Small Habitats
Source Institutions
In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

Cellular Soap Opera
Source Institutions
In this activity, learners create a large film of soap and experiment with what can and cannot pass through it.

Using Bubbles to Explore Membranes
Source Institutions
In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.

Exploring Structures: DNA
Source Institutions
In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

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.

Protein Factory
Source Institutions
In this activity, learners take on the role of various parts of the cell in order to model the process of protein synthesis.

Coral Spawning Globe
Source Institutions
This activity models the mass coral spawning event that takes place at Flower Garden Banks National Marine Sanctuary every August.

How Might Elevated CO2 Affect Plants
Source Institutions
In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

Build-A-Membrane
Source Institutions
In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins.

Tools of Magnification
Source Institutions
In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

Microbes are Everywhere
Source Institutions
In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

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.

The Dead Zone: A Marine Horror Story
Source Institutions
In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

Biotech in a Bag
Source Institutions
In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

See the Colors in Leaves
Source Institutions
Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.

Do Plants Need Sunlight?
Source Institutions
In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

Born of Blood: Craft Stick Chromosomes
Source Institutions
In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes.

Fruity-Glows: Pictures of Health on a Microarray Canvas
Source Institutions
In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

Dinosaur Bone Experiments
Source Institutions
This activity features two connected hands-on activities about dinosaur bones.
