Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

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 the kitchen, learners can perform their own density investigation.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

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

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 about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.

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?

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

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

Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.
