The 1590s saw the invention of the first compound microscope. Scholars learn about how microscopes work and how to properly focus one. The lesson stresses the science fields that use microscopes and the difference between electron...

Many fields of study require a specialty and a sub-specialty as you progress through your education. Scholars learn about six sub-specialties of life science. From botany to zoology, our knowledge of the world of living organisms expands...

Hyenas normally hunt alone, however scientists discovered that in Israel, hyenas hunt with wolf packs. When relationships develop between different species, we call it symbiosis. The videos teach about the three types of symbiosis and an...

"We Are Never Ever Getting Back Together" makes the perfect theme song for meiosis. The simulation encourages scholars to move the chromosomes and chromatids to properly illustrate the meiosis break up. Multiple-choice questions allow...

Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.

We can see the result of electricity  but not the process itself. The simulation compares electric circuits to a water tower and water wheel cycle. Young scientists adjust the height of the tower, the amount of resistance, and if...

Tommy is stuck in a dungeon and can only escape if you can discover the correct formula for velocity! Through trial and error, scholars enter the velocity required for Tommy to reach the elevator at the proper time. Then they extrapolate...

If your pupils think relative velocity is the velocity at which you can run away from your relatives, they need this simulation. Two bikers want to meet at a specific time. Scholars alter the velocity of one rider to arrange the...

How do we know how long ago a dinosaur lived or an ancient fire pit was used? Scholars learn about the application of carbon dating and half lives to discover things about the past. They adjust the amount of radioactive carbon in the...

Everything is made up of atoms, but what are atoms made up of? The simulation explores subatomic particles. It focuses on hadron, boson, and lepton groupings as scholars learn about quarks, neutrinos, gluons, and more.

What are some simple uses for an electromagnet? Scholars explore the electromagnetic circuitry in a doorbell through an interesting simulation. They control the core material, number of loops, amount of current, and strength in a spring....

Create a shift in TV viewing habits. The interactive presents a cosine model of an individual's TV viewing habits during a year. Class members move the model to reflect given conditions. Finally, they determine key features from the...

Who needs a plan — let trigonometry protect you! Pupils determine the angle of an approaching enemy to a village wall. The scholars determine the exact value of trigonometric functions for the angle. Class members use trigonometry to...

Change the y-intercept by adding a constant to the function. Individuals move three functions vertically along the y-axis. As they observe how the equation of the functions change with the vertical movement, learners determine how...

Who wouldn't want to wear four pairs of sunglasses? Each pair of sunglasses reduces the percent of incoming light by one-half. An interactive tutorial helps young mathematicians build a graph that models this scenario. They...

Explore a geometric sequence model through a simulation. Learners change the starting drop height of a ball and watch how the heights of following bounces change. They consider the ratio of the consecutive bounces as they analyze...

Study logarithmic properties using a triangle. A clever manipulative shows how a triangle can represent the three parts of a logarithmic or exponential equation. Pupils review the concept and then answer guiding questions to further...

How can an object as heavy as an airplane fly? Turns out the answer is quadratic! Your classes explore the Bernoulli Effect through an interactive graph representation. As a plane increases in speed, the lift force also increases. Young...

Learning about tangents doesn't have to be a slippery slope. Pupils drag a point around a unit circle to see how angle affects the slope of a line. They individually answer a set of challenge questions to come to the conclusion that...

[Free Registration/Login may be required to access all resource tools.] Describes the weather fronts that occur when two air masses collide. Includes downloadable handouts.

[Free Registration/Login Required] In this interactive simulation, the user will help guide the driverless car using vectors.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will be able to determine the number of valence electrons for any element and draw an electron dot diagram for any atom....

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will explain the law of conservation of mass, the law of definite proportions, and the law of multiple proportions. They will also...

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will define a mixture and understand why mixtures are different than pure substances. They will classify mixtures as homogeneous or...
