How random is random? Demonstrate the different random sampling methods using a hands-on activity. Pupils use various sampling techniques to choose a random sample of elements from the periodic table. They use the different samples to...

Where does our garbage go? What is the difference between a recyclable and non-recyclable item? Pose these important, but often overlooked, questions to your class and invite them to consider the lasting and damaging effects of the...

The battle at the Alamo may be one of the most famous military campaigns in Texas history, but it is by no means the only one. As part of their study of the military history of Texas, class members research less-well-known sites, locate...

Make sure your scientists are reporting their work effectively by providing them with a reference for their lab reports. The first few pages of this resource detail each element of a lab report, and the last few pages provide an example...

The Catcher in the Rye is the focus of a sampler that models some of activities included in a for-purchase packet based on J. D. Salinger's novel.

A deceptively simple question setup leads to a number of attack methods and a surprisingly sophisticated solution set in this open-ended problem. Young geometers of different strengths can go about defining the solutions graphically,...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

How can you relate colligative properties of solutions to everyday situations? Pupils first discuss the concepts of density, boiling and freezing points, then demonstrate how to accurately determine the boiling and freezing point of...

It might not be easy, but it is worth recycling electronics. Small groups determine the percentage of the materials that make up an iPad 2 and display the information in a circle graph. They then research the recycling process for...

Herbivores and carnivores just don't get along. Using a box of animal crackers, classes collect data about the injury status of herbivores and carnivores in the box. They complete the process of chi-square testing on the data from...

How many nurses does it take to support one doctor? A project-based activity asks learners to analyze state data to answer this question. Classes create polynomial functions from the data of doctors and nurses over a seven-year...

Acceleration, velocity, mass, and gravity all play a role in the motion of a rocket. Young scientists explore the connection among these components using an interactive tutorial. They adjust the mass and thrust force to experiment with...

Here's a resource with more bounce for the ounce! Engage your physical science class with an interesting interactive that allows individuals to perform tests with a mass attached to a spring. Participants can customize the scenario by...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

Who doesn't love gold and silver? Brine shrimp, that's who! Learners conduct an experimental lesson to monitor the toxicity of gold and silver nanoparticles on brine shrimp. They synthesize solutions to expose the brine shrimp to and...

How much can opinion influence a news story? A standalone resource discusses the importance of John Brown's Raid through the lens of journalism. Learners analyze two different texts, one from the perspective of the North and the other of...

Rumor has it exponential functions help solve problems! In a kingdom filled with rumors, young scholars must determine the speed a rumor spreads. The ultimate goal is to decide how many people must know the rumor for it to spread to the...

Free yourself from the shackles of traditional math lessons. Young mathematicians investigate race, gender, and age differences in California's prison system. They use provided graphics to compare the prison population with the state's...

Pupils record temperatures at different locations around campus. They examine the results and draw conclusions about how materials and colors affect the amount of heat produced. They also analyze Los Angeles' temperature records over a...

I can't calculate a base-2 logarithm since my calculator doesn't have a base-2 log key. Young mathematicians use the change of base formula to extend the properties of logarithms to all bases. Among these bases is the natural log base,...

Individuals learn how to plot rational numbers on the number line in the sixth lesson of a 21-part module. They identify appropriate units and determine opposites of rational numbers.

Learn about the opioid and overdose epidemic in America with an article that explains what opioids are, how they are used, and how they are abused. Learners discover the death rates associated with opioid overdoses and other factors that...
