How sustainable are cell phones? Throughout the unit, learners explore the issues around cell phones concerning sustainability. Class members take a graphical look at the number of cell phones across the world using a box-and-whisker...

Why is the weather man wrong so often? Young climatologists discover how chaos rules both weather and climate through a math-based activity. Using an iterative equation, the class examines how small day-to-day weather events total up to...

How many calculations can you think of that include moles? Chances are, plenty! Show young chemists the uses of the multifaceted mole with thought-provoking puzzles. Individuals identify and associate the outcomes of molar quantities...

Take a shot using a lesson on volume! Young learners watch a video showing a trashcan filling with paper balls. The task is to calculate the number of paper balls that will fit in the can. Pupils use volume calculations to make a...

Learners explore logic and use Geometer’s Sketchpad and patterns of logic to solve a puzzle.

Investigate the effect of false positives on probability calculation with an activity that asks scholars to collect simulated data generated by a calculator. To finish, participants analyze the probability of certain outcomes which lead...

You are used to teaching repeating decimals with bar notation that keeps us from writing that number over and over again; now teach what the over and over again represents. This activity allows your mathematicians to explore the infinite...

This activity begins with a review of linear functions and segues nicely over its fifteen examples and problems into a deep study of exponential functions. Linear and exponential growth are compared in an investment task. Data tables are...

A mid-module assessment uses two multi-part questions to measure progress toward mastery on descriptive statistics standards. Each part of a question addresses a single standard to help determine mastery.

Get into the swing of things. Pupils use a pendulum to demonstrate the conversion of potential energy to kinetic energy and back. After measuring the speed of a pendulum and compare it to the calculated theoretical speed, they...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Teach adolescents to use credit responsibly. The 32nd installment of a 35-part module covers how to calculate credit card payments using a geometric series. It teaches terminology and concepts necessary to understand credit card debt.

Pupils work to find probabilities by using areas under the normal curve. Groups work to calculate z-scores and solve real-world problems using the empirical rule or tables.

In 2015, Peter Cook found that sea lions with high levels of exposure to toxins suffered permanent brain damage if they survived at all. Scholars learn about the accumulation of toxins at various levels of the food chain. Using...

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

This page includes a space to write in the date, but what does the date even mean? And where does it come from? Inform your class about the various calendars and how the Western calendar came into widespread use with an informational...

The class gets to practice being a mathematician in ancient Greece, performing geometric application problems in the way of Eratosthenes. After following the steps of the great mathematicians, they then compare the (surprisingly...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

In the first of a two-day lesson on transformations with matrix notation the class transforms the unit square using general transformations, then calculates the area of the transformed image. They discover it is the same as finding...

Determine the difference between a sample statistic and a population characteristic. Pupils learn about populations and samples in the 14th portion in a unit of 25. Individuals calculate information directly from populations called...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

Combine a little solid and a little water and the solution is clear! An experimental lesson has individuals make calculations to create a sample solution of a given volume and molarity. They then create the solutions using a virtual lab...

Would you like milk with that? Young scientists consider thermal energy transfer to create the perfect cup of coffee. They calculate the amount of milk needed to reach a specified temperature and then test their calculations using a...

How many Calories one needs on a daily basis is dependent on a number of factors including gender, height, and activity level. In the third of seven lessons about energy and food, young nutritionists calculate the number of Calories...
