By overlapping combs and window screening and by looking at a printed set of consecutively larger circles, learners observe Moire patterns, which provide a visual of what happens during wave interference. 

As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur.  By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that...

Learn about George Washington Carver's important contributions to agriculture by studying the sweet potato. First graders read about the inventor's observations and prepare sweet potato slips for the class garden. Additionally, they...

It's frog party time! With frog banners, frog juice, and a triangle hunt, your garden party is sure to be both entertaining and educational. The activity connects geometry, earth science, and delicious snacks to teach kids about...

The amount of energy Americans use doubles every 20 years. The first instructional activity in a 10-part series teaches scholars about different forms of energy. They rotate through five stations with hands-on activities or experiments...

The principles and uses of inclined planes, screws, and wedges are the focus of a science lesson. In it, youngsters come up with every day examples of simple machines, and build an example of one in class. That project is then used to...

Students observe the sounds of different brass instruments in order to understand how to create different pitches. In this musical instructional activity, students create a "brass" instrument from everyday household objects. The students...

Combine science, math, and more using this resource. Learners use technology to share video and other information about their community with people throughout the state. They learn about the environment, identifying native plants, record...

Here is a terrific instructional activity that uses a special State Quarter as a learning tool. This one uses the Alabama State Quarter. During this instructional activity, pupils learn about their five senses. They make observations...

What do graphs of atmospheric gases over time show us? Do they indicate that carbon sources and carbon sinks are not in balance? Up-and-coming meteorologists watch video clips, read information, and analyze data from the HIPPO...

Physical science investigators mix sugar and food coloring into different cups of water and cooking oil to compare how the solid and liquid behave in each. As the introduction to this unit on dissolving, it is relevant.

Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...

Get your class outside to observe their surroundings with a lesson highlighting weather patterns and seasonal changes. First, learners take a weather walk to survey how the weather affects animals, people, plants, and trees during...

Students explore motion by observing the movement of people and duplicating those movements. They compare and contrast various kinds of movements and identify different types of movements in pictures. They build an object that can be...

Not all liquids are the same. Investigate the viscosity of different fluids with a series of activities designed for eighth grade science. As learners move through learning centers with different experiment setups, they determine...

Students examine containers and their capacity. They fill a one-cup measuring cup with water and pour cups of water into other containers. Through observation, students discover how many cups make a pint, and how many teaspoons make a...

There is the same amount of water on earth now as there was when it was formed. The water from your faucet could contain molecules that dinosaurs drank! Young scientists build their own hydrologic cycle model and observe...

Identify the different cell organelles in prokaryotes. Modelling the cells using Jell-o and candies will be a fun way to experience the cell in a hands-on way (different to using play-doh!). They observe cells under a microscope and draw...

What do lemurs do best? They move! Lemurs like to jump, run, hop, and climb and it's your class's job to document seven fun lemur behaviors. The class starts by discussing why lemurs are considered primates, and then they isolate seven...

Break down the scientific method to get a better grasp on the proper way to use it. A short presentation walks through each step in the scientific method and the proper vocabulary associated with each. Scholars complete the worksheet to...

Steps of the scientific method are summarized, and then an example experiment is presented to allow practice identifying the steps. The graphics and animations are a little blurry, but this otherwise well-formulated presentation will...

Young scientists will be abuzz as they sample and compare the tasty treats produced by Apis Mellifera. 

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

A chemistry instructional activity presents 14 chemical reactions for scholars to observe, write the equation, and balance the equations. Additionally, it provides ways to extend the activity as it relates to catalysts.
