Students discover how the public's perceptions of science have changed throughout recent history; then research scientific and technological breakthroughs in a variety of areas. They then create plays that allow scientists to encounter...

Students observe a teacher demo on how clouds form. In this earth science lesson, students discover how cloudiness affects relative humidity. They explain the scattering of light by clouds.

Students examine structural features.  In this life science lesson students complete an activity and quantify the impact of various modifications. 

Students explore the DNA of strawberries. In this science instructional activity, students extract the DNA of strawberries. Students complete a lab report.

First graders gain knowledge about solids, liquids and gases by taking a look at the things around them. They have to classify certain picture cards based on which category they feel the picture falls under. As a whole, the class...

Second graders examine the properties of liquids and their classifications. They compare and contrast cups of different liquids and record their findings in journals. Students observe how liquids flow at various speeds and that unlike...

First graders understand that gases take up space even though you can't see or smell it. This is done through many experiments like trapping air in different sized bags, using balloons and plastic bottles, and blowing bubbles. They...

Second graders discover how matter changes from one state to another by observing melting ice cubes. They decide on means to warm the ice and predict what will happen. Students record how long it takes for the cubes to melt.

Should we continue to spend money on nanotechnology? Groups engage in a problem-solving unique process around the newly emerging research field of nanotechnology. In order to propose a solution, the groups must research nanotechnology...

A 22-slide set provides pretty much everything you need to teach the rock cycle except the actual specimens. All of the slides contain graphics or photographs to help describe the process, and most even have links to educational videos....

Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.

Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

What kind of impact do humans have on watersheds? Find out in a lesson that defines, explores, and promotes ways to protect our watersheds. The ultimate goal of the lesson is for learners to discover how a watershed is impacted by...

Can you visualize one billionth of a meter? It's not easy to understand the scale of a nanometer. Learners use a hands-on lesson to develop an understanding of the size of a nanometer in comparison to common objects. They walk away with...

Animal reproduction in sheep and cattle is explored with the help of Punnet squares. Scholars employ tools using probability to conclude the color of wool a sheep's offspring will have. Acting as animal geneticists, pupils then take...

How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...

Elementary learners listen to a story, then sort objects from largest to smallest at six different stations around the classroom. Adaptable for a large range of age and ability groups. 

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...

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

Young scholars explain nutritional strategies of benthic organisms.They describe nutritional strategies of benthic organisms and describe these physical characteristics.

Middle schoolers examine the world of the Arkansas alligator and topics that are related to wetland environments. They pay attention to the relationship between geography, climate, environment, and the animals who live there. A role-play...

Unearth this gem of a resource to use in your geology unit! With colorful images, bullet-point text, and links to related videos, it deals with the characteristics, properties, and identification of minerals. There are also slides...

Students create a model estuary. In this modeling estuaries lesson, students identify characteristics and mix water of varying densities. Students form a hypothesis, conduct an experiment, and analyze the results.

Analyze a Happy Meal™ for nutrient content and calories. Blend the contents into "McMush" and use Biuret's solution to test for protein content. There are a few problems with the lesson plan: the resource links are no longer...
