What Floats Your Boat?

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity,...

Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

Students apply their knowledge of friction, drag, mass and gravity as they design, build, and test mini-bobsleds.

Choosing between a medicine ball and a basketball, which will hit the ground first when dropped? Learners watch as visitors at a festival demonstrate in an interview-style video. The narrator asks visitors to guess, then drops the balls....

Four types of air masses interact in the atmosphere above the US. The collision of these air masses forms a front, which, in turn, creates our weather. Concepts are explained by Sam and RJ, thus preventing a snowball fight. Your class...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

Don't make conversions a tonne of work! Use the quick video lesson to demonstrate conversions between grams, kilograms, and tonnes. Learners then use the practice problems to master the concept.
