Properties in measurement, pressure and viscosity of solids, liquids, and gases are the main topics covered in this slideshow. The explanations of Pascal's, Bernoulli's, and the Venturi effects are very clear. Easy to understand diagrams...

Turn your pupils into engineers who are able to use scientific principals to design a ship. This long-term project expects pupils to understand concepts of density, buoyancy, displacement, and metacenter, and apply them to constructing a...

Learners explore the states of matter. For this physical science lesson, students observe what happens to water when it freezes and record observations. Learners then observe ice when it melts and record observations.

Students predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.

Students investigate the concept of density by observing demonstrations. In this density lesson plan, students make observations while the teacher demonstrates the Cartesian diver, a density column, a candle trough, a wave bottle, an...

Students investigate buoyancy, displacement and density.  In this flotation lesson students study the Archimedes' Principle, analyze data and draw conclusions. 

In this liquids and gases worksheet, students review 9 vocabulary terms associated with liquids and gases by completing a crossword puzzle.

Students discover density.  In this density lesson, students discover the properties of objects that allow them to float or sink in water.

Learners investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Students observe earth science by examining results from an experiment. In this buoyancy instructional activity, students practice floating different items in two different liquids and identify why certain objects will float and others...

Third graders recognize that different materials have different properties which can be observed such as texture and bouyancy, and compare and contrast, through observation, ability of some objects to float because of action of...

Students investigate buoyancy. In this buoyancy lesson, students apply the Archimedes Principle of Buoyancy to the experiment conducted in class to determine how battleships float.

Students explore the density of soap. In this science lesson, students conduct an experiment to find which types of soap will float. Students make a hypothesis and record their observations.

Students study the different types of plastics and see which ones sink or remain buoyant.  For this ocean environmental lesson students complete several handouts, and view a film on PBS.

Learners observe a scientific experiment and pose a hypothesis. In this scientific inquiry lesson, students make predictions about the combination of alcohol in water and how it will affect a floating ice cube.

Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample...

Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Learners use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...

Learners examine the flow of water. They observe and test the properties of water by using sticks in flowing water. The lesson plan has streaming video, resource links to access, and a good hands-on activity that is clearly described in...

Archimedes' principle is practiced as chemistry learners practice computing the density of different gases, liquids, and solids. Using a chart of standard densities, they also identify unknown materials by similar calculations. Fifteen...

Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity: Carbon dioxide gas is more dense than air Bubbles are semipermeable, allowing only carbon dioxide to diffuse...

In this density worksheet, learners calculate the density of objects given their mass and volume. They are given a table with the density of a variety of substances and given the mass or volume and must find the unknown.

Match animals to their environments with a cute lab activity. Kids draw a line between each animal, such as a fish, a rabbit, and an ant, to the place where it lives. For hands-on practice, a science investigation instructs learners to...

Fifth graders complete a worksheet which has them place a list of gases in order from the least to the most dense. The density in grams is given for each. There's a good paragraph which provides background knowledge about the volatility...
