Learners brainstorm on ways they use water, and where water comes from. They view video, Down the Drain, to gain specific facts about water use, properties of water, problems of water and the water cycle. They perform a lab activity...

Through the use of a Reading Rainbow episode, clever in-class games and activities, and an ITV Series video, second and third graders engage in a study of the scientific method; what it is, and how scientists use it. This well-designed...

Sixth graders investigate the relative diameters of planets and distances between them and the cause for seasons on Earth using the 5-E Learning Model. They appreciate the size and distances involved with objects in the real universe....

Music has been said to effect short term memory. Learners test out this hypothesis, graphing how knowledge retention in a biology classroom changes when music is played in the background. In the end, a better appreciation of the dynamics...

Students investigate the behavior of isopods. In this isopod lesson plan, students make observations of an isopod and sketch the pillbug. They study the orientation of the isopods in relation to moisture in a chamber they construct from...

Redecorate a classroom on a budget. Middle schoolers rebuild a classroom after a disaster. They conduct Internet research to determine construction supplies needed and the most cost effective way to reach the predetermined results. They...

Students, in groups, use given materials to devise a way to deposit a ping-pong ball into a paper cup that is located in the middle of a 6-foot diameter circle, while standing outside the circle.

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

Advanced chemistry kids experiment with the freezing and boiling points of various aqueous solutions. They also prepare a presentation of the kinetics of solution formation and structure of the matter involved. This resource provides...

Your older elementary learners investigate electromagnetic energy and the electromagnetic spectrum. They will observe 7 items represented in the electromagnetic spectrum and make a poster of all the things the items have in common. After...

What would the world be like with no insects? Ponder this question using a research-based STEM unit that encourages scholars to investigate insects from both a beneficial and hazardous perspective. They learn about insect behaviors,...

Students prepare a sample of a commercial hand lotion for analysis by HPLC to determine the percent composition of two common cosmetic preservatives, methylparaben and propylparaben. They perform the analysis and the data is evaluated to...

Students determine the best solvent system for separating a methylene blue/sodium fluorescein mixture by thin layer chromatography. They conduct an initial TLC separation using ethanol and a different solvent mixture and analyze the data...

Designed as an overview of the benefits of a 4-H program, this presentation, created by faculty from Purdue University, would provide a terrific introduction. Those who are interested in starting a 4-H group or club could explore the...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

Second graders learn about how the food is broken down in our bodies and the job of each body part involved in our digestive system. The utilize the CD ROM game, "Body Works." This wonderful game takes pupils through the human body's...

Junior geologists work through three mini-lessons that familiarize them with the formation and location of fossil fuels. Part one involves reading about petroleum and where it comes from via a thorough set of handouts. A lab activity...

In this chemistry Olympiad lab worksheet, students are given two lab problems to design experiments. Topics include determining the mass percentage of a given compound and determining an unknown metal using quantitative and qualitative...

This 60-question comprehensive exam was designed to determine who would go on to compete in the 2000 US National Chemistry Olympiad. Hopefuls answer multiple choice questions regarding all chemistry topics taught in the first year...

Accomplished chemistry learners set up a calorimeter and measured the energy released by various alcohols: methanol, ethanol, and either propanol or butanol. Lab masters will first need to design their tables for recording data. Consider...

Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...

Investigate Hawaii's sandy shore ecosystem! Start by creating a vocabulary list and having your class complete a KWL chart. Next, pass out the "I think of" sheet. Each learner will then choose a word from a beach bucket and add it to...
