After taking in background information on teeth, marble, eggshell, and fluoride, chemistry aces design an experiment. Their goal is to demonstrate whether or not fluoride has a similar effect on marble or eggshell as it does on tooth...

The stage is set for you to guide future physicists through three forceful activities about motion. In the first, learners experiment with rolling carts to discover how objects interact. In the second, they inspect images of an object in...

What happens when two worlds collide? In the first of several activities, future physicists experiment with colliding ball bearings or Newton's cradle. Another activity requires the use of an air track with cars to examine collision....

Physicists become Olympians in a competition using centripetal force. They ride a bicycle to comprehend relationships between linear and rotational motion. If you have an old-fashioned record player, it can be used to help pupils...

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

Can you train a worm? Biology buffs will have a blast trying! Using planaria or earthworms, they introduce a certain stimulus repeatedly until the desired response happens more quickly. They also explore the response of their own eyes to...

A suggested sequence of events lays out five hands-on activities and four creative assessments on the conservation of momentum. Using spring scales and mail scales, junior physicists examine Newton's Third Law. After you have taught the...

The debate over genetically modified organisms is on! Young biologists imagine that they have been asked to choose which corn chips will be sold for a fundraiser, one made with GMOs or one without. This four-day lesson plan requires...

Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

Nine action-packed organic chemistry exercises are contained in this mini-unit on carbon containing compounds. Examples include constructing models of alkanes, producing aromatic esters, and preparing pigments for paint and dyes....

Introduce high schoolers to chemical reactions with this series of activities. In a little over an hour, scientists observe four gas-producing reactions: the combination of hydrochloric acid and sodium hydroxide, placing pasta in...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Many people think they can't observe plate tectonics, but thanks to GPS, we know that Australia moves at a rate of 2.7 inches per year, North America at 1 inches per year, and the Pacific plate at more than 3 inches per year! Scholars...

Students explore and identify phases of matter and compare the particle motion in solids, liquids, and gasses.

Physics learners make magic with inertia! By pulling paper out from under a stack of blocks or batting a rubber ball into motion, physics scholars' eyes will be opened! Don't think that this lesson is only fun and games; plenty of...

Teaching elastic forces in your physics class is a snap with this resource! Scholars compare the stretch of rubber bands with differing width, then measure the stretch of a spring and calculate force. In a whole-class experiment, wire is...

Five fabulous procedures introduce physics or chemistry classes to special properties of matter. They discover adhesion and cohesion, solubility, melting and boiling points, and viscosity through hands-on experiences. Tests are...

Push the envelope with this lesson on atmospheric pressure! Your physics or geology juniors will be amazed at your super-human ability as you demonstrate the breaking of a stick using a newspaper! They also work with peers to construct a...

Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Immerse your chemistry class in solutions! They melt and compare the mixtures that make up margarine, separate black ink into its component colors, distill ocean saltwater, and practice chromatography with plant pigments. There are eight...

Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they...

Laboratory activities encourage evolutionary biology scholars to consider homologous structures as evidence of common ancestry. They learn how to formulate phylogenic trees and that environment influences to genetic variation. Activities...

Six different chromosome activites introduce biology aces to heredity, chromosomal abnormalities, sex-linked traits, and the human genome. The hands-on activites are fairly simple for the teacher to prepare and will prove to be both...

Engage young biologists with four laboratory activities that explore the fossil record. Learners examine fossil images, a fossil kit, the rock record, and geologic time scale. They even experiment with the oxygen production of an Elodea...
