Sixth and seventh graders construct a "metric machine" as a kinesthetic aide in converting from one unit to another in grams, liters, or meters. They complete a metric activity on the Internet and view about five minutes of a video on...

Watch your marshmallows fly. The engaging STEM activity has groups create a catapult to launch marshmallows. After testing their prototypes, they consider improvements and redesign their catapults.

Explore the unique characteristics of polymers. A complete lesson begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

Students colloborate in a lab experiment. No OBJECTIVES.

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Third graders explore the difference between a physical change in a substance and a chemical change. students study the volume, density, altering shape and chemistry of a copper penny.

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

Students investigate Archimedes' Principle and show how it relates to density. In this Archimedes' Principle lesson plan, students experiment with a beaker of water, a Styrofoam "boat" and a weight. They predict what will happen when the...

Ninth graders conduct an experiment demonstrating what happens when a train hits a car using easily accessible materials. They calculate momentum, velocity, and distance using the appropriate formulas. Then they write an incident report...

Learners listen to story, "The 100-Pound Problem," compare their weight with character in story, and weigh different classroom items using nonstandard units and standard units. They experiment with different items that can make scale...

In this writing nuclear reactions worksheet, students read about nuclear equations for alpha decay, beta decay and positron emission. They are given the rules for writing nuclear reactions and a sample problem.

For this physics review worksheet, students compare experimental variable, simple machines, and Newton's Laws. Students calculate kinetic energy, work, power, speed, and velocity. Students review conduction, convection, and radiation....

Students discover the metric system through video clips and Internet activities. In this measurements lesson, students practice using the units of measure for the metric system and compare them to the less popular English system....

Students investigate the interdependence of mass and gravitational acceleration using computer simulation. In this physics lesson, students derive the formula for acceleration due to gravity. They calculate air resistance on falling...

In this simple machines worksheet, high schoolers identify the 6 simple machines. They answer 21 questions about the types of simple machines, the output force of simple machines, the input force and the work involved in using a simple...

Students explore the measurements of capacity by constructing a creative project in the shape of a man. The man has body parts that represent different units of measurement and can be used to make conversions. This is highly concrete and...

Students conduct a variety of experiments to explore gel electrophoresis. In this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Students discuss concept and specificity of habitats, both marine and terrestrial, list similarities and differences in the habitats of a kelp forest and a terrestrial forest, compare types of organisms that occupy corresponding types of...

Middle schoolers investigate which brand of chocolate chip cookies contains the most chocolate. They analyze and compare data using Microsoft Word and Microsoft Excel. They communicate the results with Microsoft PowerPoint.

Students determine the density and thickness of a piece of aluminum foil. For this density and thickness of materials lesson plan, students experimentally find the density of a piece of aluminum foil and compare it to the theoretical...

In this acceleration learning exercise, students experiment with varying amounts of mass to observe the effects on the force needed to move an object. Students apply Newton's Second Law of Motion to describe the relationship between mass...

Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.

For this first class lever worksheet, students investigate the mechanical advantage of this simple machine. Students change the effort arm and the resistance arm and calculate the resistance force, effort force and the...
