Have you ever stretched out a Slinkie so much it wouldn't go back to its original shape? Slinkies, like all springs, follow Hooke's Law. A simulation uses springs and masses to demonstrate kinetic, potential, and thermal energy. It...

Did you get to play with electric currents or were you grounded? An electrifying simulation shows how building up a charge of electricity creates a static shock once grounded. Pupils rub John's foot across the carpet and view the buildup...

Have you ever wanted to turn off gravity? This simulation allows learners to do just that in addition to altering other variables. Scholars can move the sun, Earth, moon, and space station to see how distance affects gravitational pull....

A realistic simulation uses charts to show forces, position, velocity, and acceleration versus time based on how the simulation is set up. Once those concepts are mastered, scholars use free body diagrams to explain how each graph...

Could a flux capacitor really work? An engaging simulation encourages scholars to investigate Faraday's law. They experiment with various speeds, magnitude, voltage, and different-sized coils. Hopefully experimenters will be able to...

Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.

Rate the resource as a perfect 10. Pupils use an interactive to help add and subtract numbers. They first explore how to express whole numbers using hundreds, tens, and ones, then explore how to add whole numbers by combining to make...

Here's an interactive that will be a great match for math lesson plans. Young mathematicians use an interactive game to match fractions represented numerically and as fraction models. One game assesses fractions only, while the other...

What makes fractions equivalent? Learners first use an interactive that shows equivalent fractions with fraction models and number lines. They then play a game where they must match sets of equivalent fractions with different denominators.

Mix up math lessons by incorporating an interactive. An educational interactive teaches users about mixed numbers. They first see how to convert between mixed numbers and fraction models. After completing the instruction, they play a...

There's nothing improper in learning about fractions. Scholars apply an interactive to explore models for proper and improper fractions. They then answer a set of questions in a game that requires building models for given fractions and...

Bank on your ability to write equivalent expressions. Scholars use an interactive to create expressions using coins. They then convert these to algebraic expressions and figure out how to evaluate them. A game with various difficulty...

Solving equations in two variables can't be that much harder than solving equations in one variable. Using a balance interactive, scholars solve equations in two variables. They apply inverse operations by adding -x, -y, or -1 as...

Find the right balance between concrete and abstract thinking. After using interactive balances to explore inverse operations, learners solve multi-step equations with variables on both sides. Of course, they can still use the...

Not all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.

Build on knowledge of fractions to build fractions. Pupils use interactives that require building fraction models for given fractions or mixed numbers and identifying fractions or mixed numbers for given models. A lab area lets users...

Three interactives times three difficulty levels equals nine possible games. Scholars play a online game that requires finding products, determining missing factors, and finding quotients. Multiplication tables are available to help...

Area works with decimals too. Pupils use the interactive to model multiplication of two decimals using an area model. They see how the decomposed components of the factors obtain partial products and then the complete product. Using area...

Expand the pupils knowledge of using area models to algebra. The interactive allows learners to use the same procedure of getting partial products when multiplying multi-digit numbers to multiplying polynomials. Scholars see how the...

Develop a solid understanding of multiplication. The interactive provides opportunities for learners to continue building a deep understanding of multiplication. Pupils use the application to find the product of two numbers and find...

Provide two views of multiplication. The introduction to an area model application has two modes. One mode shows the area of simple multiplication up to 12 by 12. The second mode shows how area models can be partitioned leading to the...

All that matters is the tiles. Pupils use the interactive to investigate the relationship between area and perimeter using tiles. The interactive has an explore and a game mode to accommodate different steps in learning. The game mode...

How would a pendulum work on the moon or Jupiter? To answer that question scholars control up to two pendulums including their location, length, mass, and amplitude. Added controls include changing the friction and strength of gravity....

Where can you see an aurora in North America? After completing an astronomy activity, scholars can locate the exact coordinates. Pupils plot points of the inner and outer ring of the auroral oval and answer questions based on...
