Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth instructional activity of an 11-part series. Individuals then...

If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...

Scholars generate and collect pure oxygen through a decomposition reaction of hydrogen peroxide in the fourth lesson of an 11-part series. Then, they complete six investigations into the properties of oxygen.   

The third lesson in a series of 11 begins by using thermal decomposition of potassium chlorate to determine the mass percent of oxygen. Then a second activity allows scholars to demonstrate that the resulting residue is from a...

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

View the moon changes from space while simultaneously experiencing the changes on Earth. A creative lesson allows pupils to view the big picture as they watch the orbit of the moon through a calendar period. At the same time, they see...

Common sense says that the farther a planet is from the sun, the longer the orbit. Kepler turned common sense into his third law by quantifying this relationship. Classes explore Kepler's Third Law through an interactive tutorial. They...

Investigate light in space as it encounters a large mass of matter. Learners discover the idea of gravitational lensing through an interactive activity. They adjust the size and location of the mass to see the effect on the path of...

Studying what you can't see can be challenging. Discover how scientists use indirect measurements to prove the existence of planets and estimate their sizes. The introduction explains the symbiotic movement of planets and stars during an...

Ever wonder why a siren sounds different when it's coming toward you than when it's going away from you? It all depends on the motion of the sound waves! The interactive activity demonstrates how the Doppler effect impacts the motion of...

How can math help your vehicle run better? Complete an interesting project-based learning task with your classes to determine the cheapest approach to mixing the ideal octane level of gasoline. Scholars create and solve a system of...

Gain an understanding of the complex topic of immigration with a collection of resources. Class members engage in a series of activities designed to give them insight into the factors that influence immigration policies and the effects...

Calling all subscribers! Model revenue based on individual cell phone subscribers. The project-based learning activity presents a challenge to scholars from a cell phone company. Individuals model data provided to them from the company...

Predict the year that college costs will double in your state using linear modeling. The first part of this two-part project based learning activity asks young mathematicians to use data from the College Board. They graph the data,...

We can't see most gases and we can't see things at the molecular level — but that's about to change! A simulation shows pupils the activity of molecules in a gas. The simulation allows scholars to vary the volume, heat, and...

Create a technical report explaining the components of a medical plan through a function. The project-based learning activity gives a medical insurance scenario that young mathematicians model using piecewise functions. Their analyses...

Make an informed decision when choosing a medical insurance provider. An engaging lesson asks your classes to write piecewise models to represent the cost of different medical plans. The project-based learning activity is a variation of...

Design a plan for finding the best health insurance for your money. Learners compare two health plans by writing and graphing piecewise functions representing the plan rules. Using Excel software, they create a technical report...

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...

Help a company maximize their profits! A detailed project-based learning activity examines two production scenarios. Your young scholars write a linear demand function. They then apply the function to develop a revenue, cost, and profit...

What are your chances of being audited by the IRS? An engaging problem scenario asks pupils to examine the likelihood of being audited compared to factors such as receiving a refund or claiming a home office. The final product of...

Class members blend their knowledge of functions and problem-solving skills to provide business advice to the Turbo Blender manufacturers. Through a project-based approach, learners examine marginal cost data to produce a function....
