Students study the properties of the physical and natural world. In this properties of the physical and natural world lesson, preschool students work at discovery tables to see how simple machines work, what happens when items are put...

In this deducing density worksheet, students follow the procedures to set up an experiment about objects floating in water and liquids of different densities, answer questions, collect data and complete charts.

Students investigate surface tension and bubbles. In this scientific inquiry lesson plan, students explore how the surface tension of water is able to support tiny objects that actually weigh more than the water as they collect date by...

Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Ninth graders predict when an object will sink or float based on comparison of the density of the object to the density of the substance in which it is placed.

Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...

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...

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

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

In this density worksheet, students complete a science lab experiment to determine the density that an object will float or sink in water. Students fill in a chart with their data, answer 4 short answer questions and write 1 conclusion...

Students participate in an experiment about the weight of water. They work together to discover that seawater is more dense than fresh water. They also determine which objects float and sink.

Learners define the terms "mass," "volume," and "density." The relationship between these three terms is established. They observe the differences between Regular and Diet Coke. They develop an hypotheses about why a can of Regular Coke...

Students 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...

First graders write about vehicles that float using the interactive writing procedure.

In this density worksheet, students 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.

Students observe experiments in density and describe the results. In the experiment, milk, corn syrup, and oil are added in different orders to three glasses, while one other glass contains only water. As objects are dropped into each...

Students explore the concept of buoyancy through experimentation. Given materials of various weights and composition, they drop them in club soda and determine which substances sink or float. Students discuss their results in terms of...

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...

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Begin with an introduction to famous deep-sea submersibles. Learners work in groups to gather information on different vessels and then share with the class. Each group then uses water displacement to help calculate the density of...

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...

Fifth graders complete a instructional activity 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...

Whatever floats your boat—with some additional weight. The first activity in a five-part series challenges pupils to design a boat to hold pennies. Using the design process, learners design, build, and test their boats, making sure they...
