Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

Students examine potential contamination on the environment due to products and by-products of a new industrial process. Students conduct a lab that explores the economic differences between choices of pollution cleanup and prevention.

Learners identify possible sources of health risks, types of exposures, routes of exposure, and populations that could be affected after discussing water pollution and environmental health hazards. After discussion, students conduct a...

Students construct models that demonstrate potential sources of contamination. Students select one type of contamination model (septic system, sinkhole, landfill, disposal lagoon, leaky barrels, oil spill, agricultural contamination) to...

High schoolers analyze experimental data and draw conclusions. They are able to comprehend that not all microbes are harmful--they can be helpful to humans. Students are able to comprehend specific examples of cases in which microbes are...

Third graders create reports in the fashion of small books. They write brief descriptions for a variety of topics and answering a variety of questions. They create a picture book for their individual animals. They utilize basic computer...

Students investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place...

Finding the central idea is the focus of this instructional activity. Middle schoolers write descriptions of different animals using details and descriptive language. They watch a video of kids using descriptive language, and then use...

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...

Students examine how antibiotics work and why they are effective. In this antibiotic lesson, students discover that when harmful germs get inside the body, the immune system may not be strong enough to fight the germs off.  Students...

Students compare paper making by hand and by assembly line. In this manufacturing lesson, students compare and contrast the two main ways to make paper, by hand or by machine.  Students research paper making and have a class...

What a great way to explore the scientific process! Learners conduct an experiment in which they use sugar and water to illustrate the concept of solutes and solvents. With this hands on approach, they are bound to remember what they...

After reviewing food chains, your class members participate in an arctic predator-prey game that exemplifies the impact of climate change of food availability. If you are in a hurry, skip this lesson, but if you have the time to...

There's no need to stay inside; get out of the classroom and create a scaled map of the solar system on your playground field! In collaborative groups, scholars identify the distance between the sun and other planets, place planet...

New Horizons set forth on a mission to Pluto in 2006. Ten years later, the spacecraft is still on its way. Here, enthusiastic scholars predict what they will be like—likes, dislikes, hobbies, etc.—when New Horizons arrives at its...

New Horizons began its journey to Pluto in 2006. Ten years later, it continues its mission. In that time, scholars have surely grown, but how much more will they grow by the time New Horizons reaches its destination? Find out with an...

Come take a ride on the space bus! Scholars go on an imaginary trip to pick up their peers from the inner and outer planets while reinforcing math skills. First, learners round decimals to identify each planets' distance from Earth....

Create a scaled model of our solar system in your classroom! Scholars work collaboratively to build paper mache planets and hang them in their proper position to showcase each planet's location in the solar system.   

How do scientists know what Earth's climate was like millions of years ago? Young environmental scholars discover how researchers used proxy data to determine the conditions present before written record. Grouped pupils gain experience...

Test your pupils' understanding of the scale from macro to atomic. While displaying images of different materials, learners identify what they would need to make that material visible. Their choices range from the human eye to an...

The wonderful world of Oobleck is entered in order to awaken your learner's sense of touch! As a warm up, learners put their hands in mystery bags in order to identify things that are wet, dry, hot, cold, hard, soft, rough, and smooth....

Here is a very good lesson plan on magnets, magnetism, and magnitic fields that is chock full of great activities for you to implement with your young scientists. Learners discover the properties of magnets, look at the forces of...

Young scholars investigate the relationship of the steps in the water cycle, and create a simulation of the water cycle in a jar.

Four intriguing and scientific activities invite learners to explore the natural resources of their town. The activities cover concepts such as genetic traits, organizing species in a taxonomy, the differences between different species...
