Curated OER
Water Density
Students identify and analyze the concept of density using the formula, density equals mass divided by volume. They review the differences in salinity levels of the ocean and note that the changes in density are caused by wind and...
Curated OER
Match Opposite Pairs
In this antonyms activity, learners read the ten words in a column and add a missing letter to a word in a second column that will make an antonym.
Curated OER
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
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.

The Engineering Place: Balloon Flinking [Pdf]
A lesson and activity sheet on buoyancy. Students add weight to a helium-filled balloon to keep it suspended so that it won't float or sink, but instead will 'flink.'
OpenStax
Open Stax: Physics: Archimedes' Principle
From a chapter on Fluid Statics in a Physics textbook. This section of the chapter provides a detailed discussion of Archimedes' principle, buoyant force, floating and sinking, and the role of density. Includes questions, problems and...

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.
Utah Education Network
Uen: Sink or Float
Predict and test everyday objects as to whether they sink or float.
