Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

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

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...

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 hands on scientific observation to determine characteristics of wood. They work directly with the materials and record their observations. Students test if wood absorbs water, if wood floats or sinks, and if all wood...

Let's go sailing! An instructive unit includes six lessons with multiple activities to teach scholars about density, center of gravity, buoyancy, and the Archimedes Principle. They can complete the final project of building a boat...

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...

Students 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.

Fifth graders define density as the amount of mass per volume a material contains, compare the densities of several types of materials, especially those that sink in water compared to those that float. They use two different methods to...

Learners explore the concept of density and buoyancy. In this physics lesson, students discover the different factors that affect an object's density and buoyancy in water. Learners conduct several investigations to further...

First graders develop skills of scientific inquiry. They determine which objects float and which sink.

Seventh graders are given the opportunity to use model-building as a way to help comprehend the forces and phenomena at work in the world around them. They use both successful and unsuccessful models to make inferences, refine...

In this Titanic's lifeboats worksheet, students read about the specific numbers of people on the lifeboats of the Titanic. Students answer 10 questions about the text.

In this activity, students use tea light candle holders and a student-made balance to compare the weight of equal volumes of wax, water, and clay. Students will discover that since the wax weighs less than an equal volume of water, it is...

In this activity, students see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float. This high-volume but light-weight material increases...

In this activity, students will investigate whether the temperature of water affects its density. Students will place colored hot and cold water in a cup of room-temperature water to see that cold water sinks while hot water floats. Then...

In this activity, students will see that a carrot slice sinks in fresh water and floats in saltwater. Considering the placement of the carrot slice in water and salt water, students will infer that the density of salt water must be...

Do heavy things always sink and light things always float? In this introductory demonstration and activity, students are introduced to the concept of density as they explore a rock and a wooden block in water.

In this science inquiry, students investigate whether volume or density of objects determine the floating or sinking in water. Using a rock and a block of wood teachers engage students in the discussion of density, mass and volume.

For this activity, young scholars make predictions about whether different objects float or sink, then test them. They are asked to record their observations and results for each, and compare their results to others'.

In this lesson, students will investigate different categories related to safety, organisms, sink or float, boats, seeds, and water droppers. Students will use exploration tubs to make observations.
