Density: Sink and Float for Liquids
We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

Manifest Density
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...

Density and Miscibility
The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to mixing and...

Density and Pressure of a Hot Air Balloon
Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a lesson on...

Inquiry into Consumer Products
Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

Buoyancy
Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Activity #6 'Nothing' Matters: A Demonstration
Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Activity #8 Which State Are You In?
Students define, give similarites and differences between solids, liquids, and gases. They compare and contrast a solid, liquid and gas in terms of shape, volume, compressibility, diffusion and density. Pupils classigy common...

THE WONDERFUL WATER CYCLE
Students are introduced to the processes of evaporation and condensation as they observe physical changes in water. They observe how matter changes from a solid to a liquid state. Students are explained that steam is water in its gaseous...

Earth Science: The Structure of the Earth
Students identify and complete activities about the structure of the Earth. In this Earth structure lesson, students view a Powerpoint about the Earth's layers and complete a diagram. students compare temperatures in the Earth's layers...
