Take your science class on a hypothetical field trip to Mars with an engaging astronomy lesson. After first learning about NASA's Mars rover missions, young scientists plan their own scientific investigations of Earth's...

Life has its ups and downs ... especially if you're an animal! Biology scholars engage in a population study through an inquiry-based lesson. Pupils work together to explore the factors that affect deer populations, then examine the...

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

Students engage students in an ecological inquiry. They author a presentation to the Grounds Management Committee of their school giving their recommendation for the control of the invasive species purple loosestrife (Lythrum salicaria)...

The Black Death epidemic is responsible for more than one million deaths in the United Kingdom. An inquiry-based activity has young scholars explore the rate of disease spread. They then analyze graphs showing data from epidemics such as...

High schoolers research Galileo's work and contributions to science. They make a timeline of Galileo's life, discuss the historical context for his book "Dialogue on the Two Chief World Systems" and examine his trial by the Inquisition...

Show the six-minute video, "Changing Planet: Fading Corals," and then demonstrate how calcium carbonate forms a precipitate in the presence of carbon dioxide. Separate your scientists into small groups to gather information about coral...

Many historical innovations were created for the common good. Get your students ready for life as a critical thinker with this instructional activity which defines the differences between innovation and invention. They will conduct...

From the scientific method to the function of a cell, the eBook has it all. A useful resource provides a free biology textbook with a focus on context. The text begins with an overview of the process of scientific inquiry and biology...

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...

An inventive and interesting lesson on the water cycle (and other cycles associated with it), is here for you. After doing a well-designed hands-on inquiry in class, learners also identify organisms and processes that are involved in the...

Celebrate the arrival of spring with this fun primary grade science unit. Engaging young scientists with a variety of hands-on activities and inquiry-based investigations, these lessons are a great way to teach children about...

Does it ever seem like time is slipping through your fingers? Model the passing of time with an hourglass activity in which individuals determine whether hourglasses are the most efficient way to measure time.

Seventh graders view lab stations with Xenopus at different stages of development. They identify the life stage of the sample, as well as the previous and next stages. Students must explain their reason for selecting the specific stage.

Budding chemists achieve a basic understanding of the role of heat in chemical reactions. An online worksheet gives learners instructions and questions to answer as they investigate the Chem4Kids website and perform a hands-on lab...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Third graders create a KWL chart about water. For this environmental science lesson, 3rd graders demonstrate how much water on Earth is usable. They act out the different stages of the water cycle.

Students investigate threats to our oceans by investigating items found on a beach.  In this environmental safety instructional activity, students examine several items found on a beach and identify them as natural, harmful, organic...

Youngsters become familiar with zoo animals. They sort them into categories, and choose an animal to act out. Two zoo centers are created in the classroom that have examples of the animals for the pupils to play with. Then, they choose...

How long do fresh foods last in space at the International Space Station? Which foods perish quicker than others? How can astronauts preserve their foods to make them last longer in space? Young scientists test the rates at which...

This project provides students the opportunity to investigate parasites as a possible cause of the observed frog deformities. It asks students to view web-based evidence and interpret whether it supports the parasite hypothesis. Students...

Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.

Students investigate water pollution. They develop an understanding of the behavior of organisms, of the structure and properties of matter, and of natural and human induced hazards by conducting lab tests. They present their data...
