Some basic chemistry concepts are fundamental to understanding biology. Learners explore how molecular structure plays a role in biological processes, especially the structure of the water molecule. The final page focuses on water's...

"Love it or leave it." "You're either for us or against us." Rhetoric and it's polarizing effects are the focus of a lesson that uses John Brown's attack on Harper's Ferry as an exemplar. Groups examine primary source documents,...

A straightforward approach to teaching complex numbers, this lesson addresses the concepts of complex numbers, polar coordinates, Euler's formula, De moivres Theorem, and more. It includes a practice problems set with odd answers...

The potential energy of peptides varies over time as they fold. An exploratory simulation encourages pupils to play with various strands of amino acids to observe the folding and potential energy levels. Young scientists generate all...

Ahh, the rules of attraction...intermolecular attraction! Introduce your chemistry crew to the other forces that influence the behavior of atoms and molecules alike with a simple interactive. Pupils push and pull polar and non-polar...

If you don't get along with someone, it's said that the two of you are like oil and water. Why is this? Explore the phenomenon and explain the phrase in one resource! Science superstars first observe samples of oil and water together....

Is it getting hot in here? Observe boiling from inside a beaker in an engaging interactive. Chemistry scholars heat and cool polar and non-polar solids and observe how molecules react to temperature changes. Your class' misconceptions...

Help the class find a better way. Pupils recall finding nth roots or a complex number in polar form from a previous module to find the square root of a complex number. Using the second installment in a series of 23, scholars discover it...

Navigate the world of orienteering in an informative interactive. Earth science scholars learn practical direction skills, such as proper polar coordinates and pairing compasses with maps. The interactive map allows them to practice...

How does hydrogen bonding explain ice crystals? An engaging interactive answers just that. Scholars explore how polar molecules interact and observe the changes as temperature fluctuates as well as the hydrogen bond attraction.

There are shaded areas, particles, polar equations, oh my! Teachers use the materials to see how their pupils compare to the AP® Calculus BC exam expectations. Scholars use the released items to practice on several BC topics and become...

Take a second look. Form B of the AP® Calculus BC free-response questions allow pupils and teachers to see another set of items. The six questions expand the set of items from the 2011 free-response questions. Form B items include a...

Let them eat cake. The free-response questions from an AP® Calculus BC exam cover several topics that include finding the area under a curve within the context of creating a birthday cake. Calculus concepts include finding rates of...

Learners examines the arctic food web with a short video about polar bears and an article about bears and warming temperatures. They design an arctic food web and discuss the trophic cascade that could come from climate...

Visualize the nth roots of unity. Pupils calculate the nth roots of unity and find all n roots. Learners plot the solutions in the complex plane and observe that they are the vertices of a regular n-gon inscribed in the unit circle....

Can scientists sort molecules based on their interaction with oil and water? The simulation demonstrates how this is possible. Pupils decide when to insert a molecule and observe how they sort themselves based on polarity.

Lighten up a bit with this activity! Use an old-fashioned overhead projector to shine light through a pair of polarizing filters. Place a stressed plastic object in between and display the colors of light waves revealed! Rotate the...

You'll be spinning in unit circles once you read through this jumbo-sized resource of everything you need to know about trigonometry. Each page has color-coded examples with explicit directions that detail the problems and...

In this holiday literature word search, students find 15 words in a detailed train-shaped puzzle. The words pertain to the classic book, the Polar Express.

Students create a mathematical formula to help plan ration supplies for a polar expedition. Using basic algebra skills, students identify the variables in planning for rations. They create an equation to help plan the expedition....

Science learners simulate what happens when ice breaks up and floats on water and how increased pressure on ice causes it to melt faster. They view a clip from the movie, The Day After Tomorrow, and relate their lab activities to what...

This Sparknotes quiz on social psychology includes 10 multiple choice questions that address attraction, persuasion, group polarization, and conformity. Test-takers submit their answers online for immediate feedback.

Cacti have special adaptations for living in desert heat and dryness. Polar bears have adaptations that allow them to withstand icy conditions. Humans adapt to different conditions by wearing appropriate clothing or building homes...
