Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
Invent an Animal
Source Institutions
In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.
Lima Bean Bacteria DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).
Rock Pioneers
Source Institutions
In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.
DNA the Easy Way
Source Institutions
This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.
Healthy Habitats Have Native Plants
Source Institutions
In this activity, learners help identify native and non-native plant species, learn about invasive species, and determine how native plants provide a healthier habitat.
Our Sense of Hearing
Source Institutions
In this activity, learners investigate the sense of hearing and plan and conduct their own experiments.
Desert Water Keepers
Source Institutions
In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.
Ripening of Fruits and Vegetables
Source Institutions
In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.
Flower Powder
Source Institutions
In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.
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.
How We Know What The Dinosaurs Looked Like: How Fossils Were Formed
Source Institutions
In this activity (p.7-8 of PDF), learners examine fossil formation.
Water Striders
Source Institutions
In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.
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.
Making Connections: What You Can Do To Help Stop Global Climate Change
Source Institutions
In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.
Salty Pits
Source Institutions
In this activity, learners explore how different deodorants work. Learners treat agar plates with different types of deodorants and compare the bacteria growth on the plates to the control sample.
Dress Like a Frog
Source Institutions
In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.
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.
What Molecules Make the Holes in Bread?
Source Institutions
In this activity, learners will discover why there are holes in bread.
