Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

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...

Sixth graders examine climate change in the state of Colorado. In this climate lesson, 6th graders watch 2 video clips regarding the topic and research the subtopics- snow pack, precipitation, temperature, forest fires, river flow,...

The 2009 version of the first part of a national chemistry competition is posted for your use with olympiad hopefuls. Test takers deal with 60 multiple choice questions covering an entire year of chemistry curriculum. Use this to...

Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...

Students create a state map using Playdoh. For this hands-on state geography lesson, students work in groups to form a three-dimensional  map of their state using Playdoh made at home following a (given) recipe. Students use four...

Students create a tree model. In this parts of a tree lesson plan, students read A Tree is a Plant, then discuss what trees are used for. Students use various materials to build and label their own tree.

Math rocks! Cavern design teams determine the rankings of rock types based upon desirability points. The points are connected to the properties of the rocks and their usefulness in building a cavern. 

Oh, no! An asteroid is on a collision course with Earth!. Class members must rise to the challenge of designing a shelter that will protect people from the impact and permit them to live in this shelter for one year. In this first lesson...

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...

Time is growing short. Teams work together to identify physical properties of rocks in order to determine the properties that would best suit their cavern shelter design.

Energy doesn't come out of nowhere! An engaging lesson has learners investigate energy as it transforms from one type to another. They collect data to prove that energy is not lost as it changes.

How did the beginnings of genetic research influence the Nazi party? A thorough, engaging unit incorporates the work of Gregor Mendel, the study of inherited traits, and the use of racism and discrimination during the Holocaust.

Investigate a heated topic in environmental science. Scholars team up to play the parts of gas molecules in the atmosphere. As the teacher moves about, acting as the electromagnetic wave, learners react as their molecules would to the...

Without wind, the weather man wouldn't have much to talk about! Blow away your junior meteorologists with a creative demonstration of how wind works. The activity uses an empty soda bottle and compressible Styrofoam peanuts to illustrate...

Is it possible to change the color of clouds? A three-part activity explores the scattering of light by the water droplets that make up clouds. After observing a demonstration, curious scholars conduct their own investigations of the...

Finally, an electromagnetic spectrum lab that will get glowing reviews from your class! Explore the nature of light using red and blue LED sources and fantastic phosphorescent paper. Young scientists compare the effects of blue light...

The color of the sky depends on the time of day. Young scholars experiment with scattering different wavelengths of light to recreate the color of the sky. They observe both the longer blue wavelengths and the shorter red and orange...

Model the transfer of energy during a typical 24-hour period. Young scholars use a game-like approach to learning the patterns of heat transfer through the day and night. Groups of four exchange different tokens as the energy...

Students examine the rock cycle by watching videos and then use creative storytelling techniques to tell the story of a rock as it undergoes geologic changes.

Students describe the changes undergone by rocks during the rock cycle and develop an understanding of the interconnectedness of the rock cycle.

Through the analysis of paper chromatography to separate ink from the pen found at the crime scene, learners analyze the different stains and through calculations determine the thief. 

Learners investigate the components of white light as viewed through a prism. The multiple colors of the spectrum produced are related to wavelengths and experienced through the creation of a color wheel.

Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...
