Students observe fluid motion. For this Physics lesson, students explore the principles of Pascal, Archimedes, and Bernoulli. Students list their experiences with fluid movement.

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

Students practice determining liquid densities in a short, hands-on lab activity. Students use a graduated cylinder to measure out 100 milliliters of a liquid, find its mass using a balance, and record measurements in a data table....

Eighth graders practice using correct vocabulary and apply content knowledge related to phases of matter when answering questions about situations or observations from everyday life.

This open-ended boat building exercise is meant to be part of a three-instructional activity series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat,...

Learners use an Excel spreadsheet to calculate the density various liquids. They take pictures of their results.

Eighth graders determine the density using mass and volume. In this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...

Students investigate buoyancy by participating in a lab experiment. In this density lesson, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Students analyze which items float and do not while...

Students explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Eighth graders are actively involved in the scientific method and inquiry as they form quick hypotheses based upon a teacher set of mystery liquids. They determine the need to make additional observations of the liquids.

Young scholars conduct a series of investigations on the unique properties of water. In this general science instructional activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students comprehend that hot water rises up through cold water but cold water does not rixe in hot water. They comprehend that water at temperatures above 4oC decreases in density with increases in temperature. Students answer lab...

Middle schoolers work with a partner to record observations on various materials. Working together, they calculate the mass and volume of each material and then combine them and shake them for a period of time. In their journals, they...

Students investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...

Students explore physical science by participating in a science activity. In this liquids lesson, students discuss how fluids can be affected by motion unlike solids. Students define other scientific vocabulary terms and conduct a motion...

Students engage in a lab project to study chemical reactions. They use guided questions to help facilitate the lab experience and come to the correct outcomes. The activity does not contain a true understandable objective. The activity...

Students identify the characteristics and composition of emulsions. In this chemistry instructional activity, students classify household products according to emulsion type. They explain how to make the best emulsion.

Students participate in a mini lab to explore density.  In this density lesson students view a demonstration and answer questions. 

Twelfth graders work in teams to design a method of recycled plastics purification by flotation. They base their design on the concept that different kinds of plastics have different densities and keep overall costs and purification time...

Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.

Students participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.

Young scholars watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.

Students test various liquids and identify as acids or bases. In this chemistry and pH lesson, the students use purple cabbage indicator to test a variety of teacher-provided substances, then bring in liquids from home to test acidity....

Students examine icebergs and how they are suspended in water, why ice floats, the melting process of an iceberg, and the floating behavior of ice compared to that of a cork through a lab activity.
