Students research the development and implementation of a research vessel/vehicle used for deep ocean exploration. In this oceanography lesson, students calculate the density of objects by determining the mass and volume.

Students define density and observe that things that are less dense than water will float. Students find the density of copper, iron and aluminum

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 end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.

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...

Students explore physics. For this science lesson, students discuss physics in their everyday lives. Students complete a physics worksheet.

Students predict the behavior of coffee in a cup while it is dropped during a demonstration. They relate their observations to the weightless conditions that astronauts experience in space and discuss the concept of free-fall.

Students investigate gravity.  In this weightless lesson students complete a lab activity about how a free fall might effect how one perceives gravity.

Looking for a good worksheet to help teach about the planet Saturn? This worksheet is for you! An excellent photograph of Saturn accompanies three paragraphs of text. Pupils answer five multiple choice questions based on what they've...

Seventh graders discover the definition of density through a demonstration using ethanol and ice cubes and a class discussion using a SMART Board to illustrate formulas and calculations. Students finish the instructional activity by...

Students build a boat out of cardboard and tape. They apply Archimedes' Principle to their design.

Familiarize young analysts with the relationship between words, meaning, and visual images. They consider the relationship between the painting Beach Poetry and the poem Sandpaper. They compose and illustrate an original a...

First, biology pupils research land and marine habitats along the route of skipper Rich Wilson's Great American II. Then, using colored paper clips scattered across a colored paper background, they play the predator-prey game to...

High schoolers study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.

First graders identify forms of pollution and describe effects that various pollutants can have on people, wildlife, and plants; students describe relationships between various forms of pollution and human actions.

Students determine ways to make "observations" about unknowns, such as the land beneath an ice sheet or the interior of the Earth, using tools other than sight. They build "mystery boxes" and exchange them with other groups to "map"...

Young scholars identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.

Students use a coffee cup to demonstrate weightlessness. After a lecture/demo, students read an article on free-fall. They perform a simple experiment which helps them explain the concept of weightlessness.

Students explore the concept that free-fall eliminates the local effects of gravity. They discuss what an Earth-orbiting spacecraft experience is like as well as the terminology of weightlessness. Their lab experiment commences.

Investigate objects that float and sink in water.

In this activity, students will learn about density by determining how to make an egg float in water. By the end of the lesson, students will understand that density and weight are different and that density matters in floatation. They...

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 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.

Throughout the activities in this investigation, students may have wondered how a boat made out of steel, which is more dense than water, can float. This activity addresses that question. Students will see that changing the shape of an...
