In this activity, learners explore how wind energy can be generated on both a large and small scale.

In this chemistry activity, learners explore the amount of copper in a new penny. Learners use toilet bowl cleaner to hollow out the interior of a penny with zinc inside.

In this math activity (Page 8 of the Dining Out! PDF), younger learners select items from a menu and count out the total amount needed using the fewest bills and coins possible.

In this math game (Page 15 of the Dining Out! PDF), learners figure discounts and/or profit increases for various food totals. Learners add decimals to $100.

In this math activity (Page 11 of the Dining Out! PDF), younger learners count out the total amount of money needed to purchase trail mix using the fewest number of bills/coins possible.

In this activity, learners will plan a snack within a budget. With a $20 limit (theoretical) to spend on snack for everyone, learners look over grocery store circulars and make their shopping lists.

This activity (located on page 3 of the PDF under GPS: Farm Animals Activity) is a full inquiry investigation into raising livestock.

In this activity, learners explore how engineers have developed sorting systems which integrate into manufacturing and packaging processes. Learners explore how coins are made.

Coins are everyday objects which tell a lot about the people who use them.

Learners will collect pennies to donate and will combine charitable giving with estimating and calculating with money. To start choose a charity or something to save up for together.

This is an online game about the complexities of farming. Learners will "draw" cards and make decisions about how to take care of their farm.

In this activity, learners will play a coin toss game where the highest total wins. Combine coin recognition, addition, and probability with a game learners can play on their own.

In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

A group of learners has an envelope containing a series of bank checks. A few checks are removed at a time, and the team attempts to construct a plausible scenario which involves those checks.

In this math lesson, learners apply mathematical modeling to solve a real-world storage problem, in which a manufacturing company is given two options for storing oil barrels.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

This website contains several activities. Mixing in Math Moments are activities that take 5-10 minutes that keep learners occupied, learning about the world, and using math on their own.

This activity about cryptographic techniques illustrates a situation where information is shared, and yet none of it is revealed.

In this chemistry activity, learners use chemical reactions to observe the composition of an alloy.
