To Float or Not to Float - A Lesson on Density

Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...

Do you have young scientists wanting to make new discoveries rather than just completing the same experiments? Young scientists use their observational skills to identify animals and patterns in animal behavior. Through tracking...

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

For this making observations in science worksheet, students experiment with whole milk in a pie tin with added food color. They make observations and then add a toothpick with soap on the end to the middle of the tin. They make...

In this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into a...

When was the last time your class saw a catalyst in action? Chemistry scholars observe an activated complex during an engaging experiment. Through both color change and evolution of a gas, individuals gain insight into the...

Students perform an experiment to measure the density of tap water vs. salt water.

Want to add a wow factor to your current chemical changes lesson plan? Try a microscale experiment with colorful precipitates! Partnered learners conduct 10 single displacement reactions and record their observations.

Science Bob provides instructions for a density experiment you can drink using common supplies with information on how it works.
