Curated OER
Science Word Search
For this science worksheet, middle schoolers look for the words that are related to the theme of the sheet in the word search. They also work on spelling skills.
Curated OER
Emulsion_ Compulsion
Students experiment with common household products to determine the properties of emulsions and how they fit into the classifications of matter through this series of lessons.
Curated OER
Physical Difference and Classification
Students use a microscope and observation skills to compare and contrast several physical properties and develop a classification system.
Curated OER
What's the Matter with My Jell-o?
Students work in teams of four as they conduct four controlled Jell-O experiments over a two-day period. The Family Page extends this learning to the community by providing families with challenges to explore at home.
Curated OER
Activity #7 Special Properties: A Discussion
Students identify special properties of matter (absorbency, hardness, brittleness, malleability, and elasticity). They define the term matter. Pupils investigate some of the special properties of matter to aid in classifying matter.
Curated OER
Water Quality Monitoring
Pupils comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...

Woods Hole Oceanography Institute: Activity: Demo for Density
In this experiment, students look at Deep Hypersaline Anoxic Basins, or DHABs, that are present in the Eastern Mediterranean, and make a model of a DHAB to investigate how liquids that have different densities can form layers. This...
Science and Mathematics Initiative for Learning Enhancement (SMILE)
Smile: Comparing Liquid Density
Because different liquids have different properties, density also differs. In this lesson from the Illinois Institute of Technology, students will calculate densities of water, dish-washing detergent, cooking oil, and other liquids.

Teach Engineering: Density & Miscibility
After students conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the concepts...
Chemistry Collective
Chem Collective: Identifying an Unknown Liquid From Its Density
In this activity, students use the virtual lab to design an experiment to determine the identity of mislabeled bottles using the densities of the solutions inside.
Science Buddies
Science Buddies: Stacking Liquids
In this science activity, you will stack several liquids, one by one, and create a colorful density column.
Exploratorium
Exploratorium: Science Snacks: Klutz Proof Density Column
An activity to help you create a density column that contains layers of liquids that are separated by different densities.

Serc: Exploring the Properties of Liquids, With an Emphasis on Density
Students experiment with liquids; comparing and contrasting, and creating a density tower leading to a beginning understanding of density.
American Chemical Society
Middle School Chemistry: Density Sink and Float for Liquids
See how different liquids can have different densities depending on their molecular make-up.
