Attract a Fish
Source Institutions
This outdoor activity/field trip requires a place where minnows swim, such as a local pond or brook.
DNA Extraction
Source Institutions
In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.
Is That DNA in My Food?
Source Institutions
In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.
Disease Detective
Source Institutions
This activity (on pages 35-43) lets learners analyze a "herd of elk" to detect the spread of a bacterial disease called brucellosis.
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).
Animal & Plant Cell Slides
Source Institutions
In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.
Bean Bugs
Source Institutions
In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.
Flocking for Food
Source Institutions
In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.
Grabbing a Bite to Eat
Source Institutions
In this activity, learners perform an experiment that replicates the dilemma faced by birds in acquiring food from a confined area.
Vital Signs
Source Institutions
This activity (on pages 16-23) lets learners measure each other's vital signs—the signs that help doctors understand what's going on in a patient body.
Animal Diversity
Source Institutions
In this outdoor activity, learners find, count and compare as many different kinds of animals as they can find in two different areas: a managed lawn and a weedy area.
Counting With Quadrants
Source Institutions
Millions of organisms can live in and around a body of water.
Isolation of DNA from Onion
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.
Invent an Insect
Source Institutions
In this creative activity, learners will find out what makes an insect an insect by studying examples of insect adaptations and by examining why there are so many different types of insects.
Effect of Environment on Plant Growth
Source Institutions
The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.
Flashy Fish
Source Institutions
Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.
Temperature Time Warp
Source Institutions
In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.
Invent an Animal
Source Institutions
In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.
The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.
Natural Selection in Protected and Unprotected Populations
Source Institutions
In this simulation, learners model two elephant seal populations and how they change over time. Learners start with cards representing a variety of seals.
