Theory or Law? You decide. And so will your class members, in an insightful interactive. Young scientists divide common scientific principles or statements between the two groups, then dig deeper in understanding the functions of...

The Big Bang Theory is more than a television show. Pupils read how Edwin Hubble observed other galaxies and noticed that the galaxies are moving away from each other. Scholars learn about the idea of the big bang and what happened next...

The universe is full of a mystic matter people cannot see. Pupils respond to 10 questions about the stuff in the universe. Most of the questions involve the big bang theory and dark matter. Learners find out how astronomers have found...

In this cell theory quiz worksheet, students complete an on-line game, clicking on questions and matching answer cards and scoring 1 point per correct answer. Printable version available also.

Is the transfer of energy different in bumper cars with stable versus bouncy bumpers? One of the variables explored in the simulation is bumper type; other variables are the mass and velocity of each car. This allows pupils to see the...

In this electrical activity, students draw a schematic design and build a bipolar transistor to grasp the understanding of bipolar junction transistor theory before answering a series of 28 open-ended questions. Students analyze...

A website all about planetary mysteries—it's a one-stop-shop for all things, stars, planets, and space travel. Scholars read an astronomy overview to discover the page's big ideas, then choose from the plethora of resources, including...

In this bonding worksheet, students take an interactive quiz with 15 multiple choice questions about the VSEPR Theory, bonding, the geometry of molecules, Lewis structures, resonance structures and enthalpy changes.

Take a look at another alternating sequence. The resource provides a graphical display of a sequence that alternates between two values. Pupils use the display to determine whether the sequence has a limit. Given a theory of limit,...

Why are car manufactures required to install seat belts and airbags; do they really make that big of a difference? Scholars use a simulator to determine the amount of force dissipated by a seat belt and airbag in a head-on crash. This is...

Is momentum conserved in a collision, along with energy, or are they opposing forces? Pupils vary the mass and velocity of two bumper cars along with the type of bumper in order to answer this question. Worksheet and in-simulator...

This is one super model interactive! Middle and high school science scholars examine scientific models through a simple resource. Guided, hands-on practice allows them to classify conceptual, mathematical, and physical models. Other...

When DNA research first began, it required almost an entire day to extract the molecules from a cell nucleus. Now it requires less than an hour. Scholars learn about the early theories of DNA with an online interactive, videos,...

Most people support the idea of an independent judiciary in theory until they hear about a court case that violates their principles. An informative resource explains why the concept is important. It also provides scholars of criminology...

Develop an understanding of the universe. Learners answer 10 multiple choice questions about several topics in astronomy. Questions contain information about the age of the universe, gravitational attraction, galaxies, planets and comets...

In this geometry learning exercise, students draw an illustration of a circle centered between two points. They draw three line segments. Students answer two questions about the resulting angles. A sample, interactive drawing is included...

In this magnetism worksheet, students answer ten questions about magnets, their magnetic poles, the magnetic lines of flux and how magnets work.

Explore the birth and possible death of the universe. An interactive simulation allows learners to manipulate the Hubble Constant to model the expansion of the universe from birth. Varying the constant provides different scenarios for...

What happens to radio waves, time, and light in and near a black hole? Young scientists explore what is known about observing frequency and time at various distances from a black hole. They control the size of the black hole and the...

In this viruses and evolution worksheet, students read an article on line about the avian flu virus and its evolutionary changes. They answer ten questions about the article including topics such as natural selection, mutations...

How do scientists discover treatments for cancer? A presentation and accompanying worksheet explain how one cancer spreads and a theory of how to stop it. It details the trials and relapses after using the medication. Scholars learn...

In this static electricity worksheet, students complete nine questions about electron charges, coulombs, potential energy, voltage and the Van de Graaf generator.

In this scientific theory instructional activity, the student is asked 46 questions about equivalent circuits designed with differently constructed power sources.  The answers are available if the student is working online.

Some genes link to others that have implications for inheritance. A set of resources lead pupils through the history of this discovery. They explain how chromosomes recombine and which parts are more susceptible to this linkage....
