Curated OER
How Do We Breathe?
Students study the structure of the lungs. In this lung structure lesson, students use lung models to study the structure of lungs and experiment to measure the amount of air in the lungs.

Titanic's Lifeboats
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.
Curated OER
Uses of Pumice
In this pumice worksheet, students read about how pumice if formed and the different uses of pumice. Then students complete 4 short answer questions

Science Is Fun: Bowling Balls Float or Sink?
In this experiment, you test whether two different bowling balls will float or sink, then determine the density of each of the balls to see if they are less than that of water.

Serc: Mn Step: Sinking Water: Glaciers, Ocean Currents and Weather Patterns
A lesson where students learn how warm water is less dense than cold water, and what this means for global climate change as ice from the polar regions melts. Students will do experiments in buoyancy and water density when hot or cold,...

Uen: Floating and Sinking Potatoes
After the teacher puts pieces of potatoes in water and salt water, the students predict what is going to happen and try to name what makes this happen.

Middle School Chemistry: Density: Sink and Float for Liquids
Young scholars determine whether a liquid will sink or float in water by comparing its density to the density of water.
American Chemical Society
Middle School Chemistry: Density: Sink and Float for Solids
Students determine whether an object will sink or float by comparing its density to the density of water.

Inquiry in Action: Compare the Density of an Object to the Density of Water
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...

Science Buddies: How Much Weight Can Your Boat Float?
Have you ever wondered how a ship made of steel can float? In this project you'll investigate how much weight boat hulls of various shapes and sizes can support without sinking.

Serc: Mn Step: Sink or Float: All Liquids Do Not Have the Same Density
An experiment in density. After a review of floating and sinking of different materials, students test four bottles, all holding four ounces of water, to see if they will float or sink. They each contain a different density of sugar...

Serc: Investigating Density in Solutions: How Can You Make an Egg Float?
In this activity, young scholars 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....

Teach Engineering: What Floats Your Boat?
Learners use modeling clay, a material that is denser than water and thus ordinarily sinks in water, to discover the principle of buoyancy. They begin by designing and building boats out of clay that will float in water, and then refine...

Serc: Density of Solid Objects
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.

Serc: Mn Step: Solid and Liquid Density Investigation
For this activity, students investigate whether objects and liquids float or sink when placed in water. As they proceed, they will develop an understanding of what density is. Student handouts are provided.

Science Is Fun: Sinking and Floating Soda Cans
An experiment to determine if either a regular or a diet can of soda will float or sink when placed in water, and what causes this.

Serc: Water Activity
Students investigate water by estimating how long it takes to freeze, then see if the ice cube will float in water, and eventually work with other items to see if they sink or float in water.

Serc: Mn Step: Sinking and Floating Water
An experiment in density where colored water, both hot and cold, are poured into containers of water at room temperature. Students will observe that the warm water rises and the cold water sinks due to their different densities.
