Fifth graders examine ecosystems in their schoolyard. In this nature and ecosystem instructional activity, 5th graders map their schoolyard into workable plots. They classify plants and animals found in the plot. They revisit their site...

Take your biology class' understanding of biodiversity to a whole new level! Ecology scholars use data to calculate three different diversity indices based on the organisms in the Gorongosa National Park. The four-part activity uses an...

Fifth graders define vocabulary terms, identify the characteristics of a pillbug, and create a dichotomous key. Then they examine the pillbugs and make observations and record these observations. Finally, 5th graders observe specific...

Learners test their local aquatic site to determine its water clarity. They collect a water sample and measure its turbidity using a sensor, then they repeat the experiment to obtain a second turbidity reading to find the average value.

A change in a parameter can end in overpopulation. The resources gives pupils the opportunity to control the parameters of rabbits and wolves in a natural setting. Using the set parameters, the simulation runs and displays the population...

Field trip! The class will review what they know about organisms that dwell in freshwater ponds, then trek down to the old water hole to collect specimens for examination. This includes several web links, useful tips, and an excellent...

Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

Learners examine trees. In this tree lesson, students create a model of a tree and its parts.

For this activity learners explore earth-friendly materials that can be used in home environments. They learn about the relationship between the environment and design, and use a variety of problem-solving strategies. They work in...

Students map and describe small area of the schoolyard and discuss habitats.

Ninth graders research the average temperature and precipitation of a prairie region to determine the type of climate it is, and how it differs from other biomes. They examine the types of adaptions animals have made to live in the...

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

Students discover the reproductive parts of a plant.  In this biology lesson, students identify and categorize several different plants they dissect in class.  Students record their information using a data chart.

Fourth graders conduct an experiment demonstrating the effects of water and air temperature on precipitation. They create graphs demonstrating their findings using Claris Works for Kids.

Tenth graders estimate the size of an adult cheetah by research and measurement of a picture. They determine the approximate distance and speed of the cheetah from a filmed chase and compare that to their own running speed.

Fifth graders study six major biomes, graph temperature and rainfall, and present their findings to the class.

Young scholars recognize the correlation between the trash they dispose of around their school and the environmental hazards that face wildlife, specifically the Laysan albatross. They determine three ways that they can help the...

Second graders observe some everyday common objects in order to attempt to learn about simple systems and how they fit together. They observe small details in order to identify the parts of a whole design.
