Tells the story of how Archimedes discovered the Archimedes Principle and his water displacement method for determining the volume and density of an object. Provides an explanation and several examples of how it is done.

Students discover the concept that density is a characteristic property of water by measuring the volume and mass of water and calculating its density.

In this activity, students' will use a force sensor to measure the weight of a water filled funnel as it drains. They analyze the weight versus time data and describe it using concepts of slope and intercepts of a linear function.

How much water do you use everyday? Find out in this engaging investigation, where you compare your water usage with your classmates and other people around the world. An exploration filled with lots of math and science that students are...

Students are introduced to our planet's structure and its dynamic system of natural forces through an examination of the natural hazards of earthquakes, volcanoes, landslides, tsunamis, floods and tornados, as well as avalanches, fires,...

In this lab, middle schoolers will measure and combine colored liquids to receive the expected results. The intended outcome would be to take primary colored liquids, measure them and combine them to create a "rainbow" colored set of...

Students will use two different methods to determine the densities of a variety of materials and objects. The first method involves direct measurement of the volumes of objects that have simple geometric shapes, while the second uses the...

In this first part of a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate the densities of several common, irregularly shaped objects with the purpose to resolve confusion...

In simple terms, density is the mass of anything - including air - divided by the volume it occupies. In the metric system, which scientists use, we usually measure density in terms of kilograms per cubic meter. The air's density depends...

Students act as chemical engineers and use LEGO MINDSTORMS NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and...
