Explain the timing of a lake cleanup to the EPA using calculus. A project-based learning opportunity has learners compare rate functions to compute a total change. Their solutions explain the time needed to rid a lake of pollutants.

It's important to have the correct number of flower arrangements at a wedding. Scholars match an inequality and a graph given a situation involving roses for wedding receptions. A set of challenge questions checks the matching pairs.

Consistency is the key. One lemon wedge per glass of water makes a nice glass of lemonade. Young scholars must identify the number of lemon wedges they need to make the same lemonade in a big gulp cup. They develop their own...

Beetle population, climate change, and acidification are all real environmental threats. Scholars display their knowledge of these threats and offer solution strategies in a four-question assessment resource. Questions from the AP® exam...

Mathematics is stronger than a card house. Pupils watch a video of the beginning of the building of a triangular card house. Scholars come up with questions they wonder about from the video and ask for more information to arrive at an...

In this mixtures instructional activity, students read about mixture and what determines if a solute dissolves in a solvent. They answer three questions about solutions and determine from a list of compounds which are soluble in water.

For this determining concentration worksheet, learners are given the equations to find the concentration of a solution in grams per milliliter, to determine the concentration in parts per million, to determine percent mass and percent...

The resource is the real deal. Individuals investigate the imaginary zeros of f(x) = x^2 + 1. They accomplish this task by using an interactive that shows input values x = a + bi and output values x^2 + 1 on a complex plane.
