Your microbiologists explore the graphing of exponential growth functions using bacteria, like e. coli and salmonella, in a well-written, career and technology lesson. 

Introducing inverse functions! The 20th installment of a 35-part lesson encourages scholars to learn the definition of inverse functions and how to find them. The lesson considers all types of functions, not just exponential and...

Lettuce talk for a moment about your culinary scholars; do they have what it takes to create a great salad? Show them the finer points of salad preparation with a career and technology lesson that combines direct instruction, creativity,...

Step into the role of a zoo director with several activities about animal training and running a zoo. Kids calculate the amount of food each animal needs, design a habitat for penguins, decide how to breed bottlenose dolphins, and train...

Take a functional approach to the national debt. Learners collect information about the national debt by decade and plot the data. They determine whether an exponential curve is a good fit for the data by comparing the percent changes...

Time to study the most sensible function — rational functions! The seven-lesson unit develops the concept of a rational function through a connection to rational numbers and fractions. Scholars graph functions, solve equations, and...

Ancient texts, like Homer's Odyssey, mentions navigating ships by observing constellations. Pupils learn about the link between history and astronomy as they relate to navigation in the Bronze Age. Scholars complete two hands-on...

Darwin explained the connection between species of finches 150 years before scientists understood DNA. Technology and progressing science proved he was right, yet many struggle to understand how natural selection happens. Scholars use...

Animal reproduction in sheep and cattle is explored with the help of Punnet squares. Scholars employ tools using probability to conclude the color of wool a sheep's offspring will have. Acting as animal geneticists, pupils then take...

Do big bodies make big brains? Let your learners decide whether there is an association between body weight and brain weight by putting the data from different animals into a scatterplot. They can remove any outliers and then make a line...

Scholars harness the power of microbes with an engaging activity that uses yeast to break down sugar in water. Multiple setups of the same experiment lets learners determine which temperature results in the fastest rate of...

Future engineers test different alloys to determine the specific strength of each one. Based on the results, they make a recommendation to NASA on which alloy to use on engines for spacecraft.

Make solutions to projectile motion problems magically appear using equations. Pupils watch a clip from a Harry Potter movie and find the length of time it takes for a remembrall to fall into Harry's hands. They use a projectile motion...

Have you ever been told that your new car begins to lose its value as soon as you drive it off the lot? Aspiring accountants take on the concepts of depreciation and book value through an easy-to-deliver career and technology lesson. The...

Slip sliding away. Groups investigates the two types of friction by running an experiment that allows them to calculate the coefficient of static friction and the coefficient of kinetic friction. The experiment uses a box, a...

Once you know how to graph y = b^x, the sky's the limit. Young mathematicians learn to graph basic exponential functions and identify key features, and then graph functions of the form f(x) = ab^(x – h) + k from the function f(x) = b^x.

Here's a workshop for teachers that rocks the academic world! Using earthquakes as a medium for instruction, educators learn about crosscutting engineering with science. Fun, hands-on, collaborative exercises encourage participants to...

Ever wonder why Pluto isn't considered a planet? Or how large the Earth is compared to the other inner planets? Explore the universe with a series of projects that simulate different aspects of our solar system. The activities require...

There are only 10 types of people in the world: those who understand binary and those who don't. The lesson includes four activities in which students learn binary, convert binary to images, understand CCD arrays, and interpret...

Explore decimals with upper graders. They solve problems from their textbook involving decimal multiplication. Afterward, as a class, they check their answers by comparing them to those projected with an overhead projector.

Students work with large numbers when determining the height of a stack of $20 bills.

Students read about the changes in the "new money" and then create a graph to represent various combinations of currency produced.

Students explore ways a sextant can be a reliable tool that is still being used by today's navigators and how computers can help assure accuracy when measuring angles. This activity will show how computers can be used to understand...

Students explore perimeter. In this geometry and measurement lesson, students create squares and rectangles using given perimeters. Students construct four sided shapes with given perimeters using the computer program "Math Keys:...
