Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

Learners make a counting/estimating jar to exchange with friends or bring home.

In this Cyberchase activity, have fun measuring volumes and enjoy a delicious shake.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

In this math lesson, learners rotate through six estimating and measuring centers. First, learners read the book, "Room for Ripley" by Stuart J.

Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

In this activity, learners examine the culture and history of the tomb site.

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

In this activity, learners create a kind of balance device using a wire coat hanger, some string, and paper cups.

In this outdoor activity, learners measure familiar objects in nature to practice working with the metric system.

Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this online activity, learners will explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.
