A variety of concepts are covered in this PowerPoint which gives the main engineering points of different aircraft types. Each slide details the engineering behind non-rigid and rigid categories of lighter or non-lighter than air...

Physics stars will enjoy learning about the conservation of energy as you demonstrate gyroscope precession. The lecture is broken into five subtopics: cross product, rotating vectors, angular momentum, rotating rigid bodies, and torque...

In this physics worksheet, students use the clues given on the sheet to complete the crossword puzzle on simple machines. There are 18 clues to solve in the puzzle.

Young scholars begin the lesson plan by identifying what a polygon is and hypothesizing how many struts (diagonals) it would take to make a polygon rigid. They watch a "Magic School Bus" episode then experiment with various shapes to...

Students construct an experiment to test the rigidity of compressed air and its strength. In this earth science lesson plan, students are divided into groups, and by putting their thumb over the end of a straw, use the compressed air...

Students create a paper model to illustrate sea-floor spreading.

College-level or AP chemists use phthalic anhydride to synthesize two different polyesters, one linear and one cross-linked in structure. A detailed materials list and well-written procedures are provided on a lab sheet. Learners write...

This in-depth organic chemistry lab walks learners through an investigation of the effect of initiator concentration on the resulting molecular weight of polystyrene. It is important that you use this lesson with experienced chemistry...

Insolubility and density? Yup, it's art class, of course. To create insoluble paintings that continually move and change, kids mix water-based paint with mineral oil and seal the mixture in laminating pouches.

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

Help your students write descriptive lab reports! Designed for ESL students but useful for mainstreamed kids as well, the activity prompts students to think of substances that match twenty given adjectives ("salt" for "soluble," for...

Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce...

Here is a set of pre-lab, lab, and post-lab lesson plans on plate tectonics. After completing the previous labs on volcanoes and earthquakes, sixth graders use the gained knowledge to explore plate boundaries and the movement of...

Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a lesson on...

Use this art instructional activity to study insolubility and density. Combining water-based paint and mineral oil will cause a fun and interactive painting. This is a great art project to incorporate during a science unit.

Your geology class practices taking core samples of a potato to examine the stratigraphy. This is a terrific modeling lesson that helps youngsters visualize strata that cannot be seen from the surface of the ground. The directions...

Brilliant graphics depict a variety of allotropes, especially the allotropes of carbon. Some notes are available to help make these useful for teaching your young chemists, but not for every slide. With some additional preparation on...

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

Put your class's observational skills to the test with a science experiment about paper and plastic bags. After reading some background knowledge about the materials in plastic grocery bags, third graders interpret a chart to answer a...

After reading a short and informative paragraph on animals and their environments, learners look at pictures of four animals, and write a short description of how each one has adapted to its environment. A suggested activity is that each...

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

Set the stage for a unit or lesson on the African savanna by creating a cute habitat diorama. Cheetahs, lions, zebras, and elephants are all present in a shoe-box-sized craft that requires your learners to color, cut, and paste. These...

High school physical scientists collide with motion. They work in pairs to design a paper car that will protect a raw egg during a head-on collision. Measurements of distance traveled, time of run, vehicle specs, and photo gate flags are...

Whether or not Galileo actually dropped balls from the Leaning Tower of Pisa, this demonstration will solidly demonstrate that objects are accelerated at the same rate, regardless of mass. You will, however, need a vacuum pump and a few...
