Students practice bleaching recycled fibers. Using colored copy paper, they cut it into strips and put it in a blender with water. They filter the pulp and stir in the bleach. They compare the original paper with the bleached sample...

Learners review properties of materials and define what pH tells them about matter.  In this pH levels lesson, students determine whether materials are acids or bases using indicator substances.

Students complete an online simulation of the greenhouse effect. In this lesson on the greenhouse effect, students use a website, similar to a webquest, to simulate and answer questions on how the greenhouse effect works. This lesson is...

First graders discover that a chemical reaction is responsible for the effects seen with Crayola Color Wonder markers. They observe that the color changes are the result of a chemical reaction between chemicals in the Color Wonder paper...

Learners study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.

Kids observe, classify, and measure tree leaves with a scientific eye. They examine leaves, group them according their attributes, and use standard units of measurement as they compare their sizes. They access a web site to learn how...

Explore the properties of gases through one activity and two investigations in which super scientists observe the changes gas makes when encountering different conditions.

Second graders use a magnet to "race" objects from one side of a racing track to another. They predict what the results are, then run the race. Pupils sort and graph which items were successfully moved, they attempt to race again. This...

Young scientists take a close looks a samples of sand that come from three different beaches. They use microscopes to view the three slides, and make observations on a worksheet. At the end of the lesson, learners share their...

I love mixing arts lessons with core content! Here, the class will discuss energy, motion, and force (push/pull) as they review dance vocabulary and movements. They preview vocabulary for force and dance. Then they pair-up to dance a...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

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...

Second graders explore floating and sinking and make predictions about whether certain objects are likely to sink or float. They read the story Who Sank the Boat? by Pamela Allen. Pupils loacate rhyming words and discuss the events of...

Combine measurement, following directions, physics, and art with one fun activity. Learners read a set of instruction to create three different kinds of paper airplanes. They measure, fold, and fly the planes, and record data and answer...

Emerging electricians extend mental models of light bulbs and resistors in series and or in parallel circuits to include the connection of photovoltaic cells in arrays. They investigate open circuits, using a DC voltmeter, a light...

Students discover how clouds form and how air pressure and air temperature affect their formation. The instructional activity is delivered in the story of Mike Breezy, Air Detective, who tries to solve The Cloud Case.

Students extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing of ships. students discover that most ships are constructed very similarly-whether they are schooners or destroyers.

Here is a beautiful lesson on clouds designed for your 1st graders. Learners study three different types of clouds. They construct drawings of cumulus, cirrus, and stratus clouds. The Cloud Book, by Tommie dePaola is used to...

Fifth graders explore electrical concepts and host a guest speaker. This lesson sets up guidelines for students to follow when they have a guest speaker. Students are primed to become actively involved in a lecture or discussion, while...

Construct paper tubes and then try out a few optical illusion tricks: See a virtual hole in your own hand Get a grasp of how the eyes combine images Notice that one eye is dominant over the other Reveal how your eyes adjust to...

Knowing the names of the steps of the scientific method is not enough; in order to really understand each of the elements, one must practice. Beginning with an engaging recap of the steps of the scientific method, learners practice the...
