Density and Miscibility
The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...
Santa Monica College
The Density of Liquids and Solids
There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson plan of an 11-part series. They then determine the density of...
Curated OER
The Open Ocean, What is it and How Does it Change?
Students investigate the ocean environment. In this ocean lesson plan, students discover the physical properties of the ocean. Over two days, students work in small groups investigating ocean maps and creating water currents.

Acoustics: The Sound Lab
If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

Staying Green While Being Clean
Clean up the environment with a lesson that focuses on replacing hazardous cleaning supplies with green, environmentally-friendly products. Using a dirty patch of surface as a control area, kids clean other parts of various surfaces...
Curated OER
Making Cents of Density
Students utilize their knowledge of the physical properties of matter such as mass, volume, and density to solve a problem. They utilize the scientific method to solve a problem. Pupils analyze their data to determine whether their...
Curated OER
Change It
Fourth graders expand their knowledge about how the physical properties of a substances can be changed. They are given multiple opportunities, using first-hand experiences and familiar objects in different contexts, to identify...

Volcanoes: Fifth Grade Lesson Plans and Activities
Fifth graders explore volcanoes and the rocks they produce using the Internet. The lab portion of the lesson prompts young scientists to compare and describe igneous rocks. Next, they critique a pair or more of...
Normal Community High School
Density
Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes'...
Curated OER
Water Cycle
Students perform experiments with water to observe the principles of evaporation and condensation. They make models of the water cycle and discuss the processes that occurred in their experiments with their jars of water.
Curated OER
Measuring Natural Objects
Students predict the measurement of objects. In this measurement lesson, students estimate the measurements of objects in a lab. Students measure irregular objects and generate scientific observations.
Curated OER
Is Your Water Clean?
Students compare water quality of different sources. They test water samples for odor, phosphates, pH, bacteria, and dissolved solids. they fill out a data table and answer questions about their findings.

More on Conduction and Convection
Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a lesson on...
Curated OER
Is Dilution the Solution to Pollution?
Learners explore the different types of pollution. they conduct experiments using dye mixed with tap water to measure the levels of dilution. They discuss at what point the dye (pollution) would be diluted enough to be safe to drink.
Curated OER
Physics Post-Lab
Students explore physics. In this science activity, students discuss physics in their everyday lives. Students complete a physics worksheet.
Curated OER
States of Matter: Liquid
Students work in a mini lab where they measure the temperature every 30 seconds for several minutes as water is heated. They are asked what makes liquid different from a solid. Students view a PowerPoint on the model of liquids,...
Curated OER
Get Down With Density
Students define density and observe that things that are less dense than water will float. Students find the density of copper, iron and aluminum
Curated OER
pH Scale, acids and bases
Eighth graders define the pH scale, acids and bases. They distinguish between acidic and basic solutions using litmus paper. Students review simple chemical formulas. They define the subscript and coefficient in terms of chemical...
Curated OER
A Matter of Fact
Third graders define matter as anything that takes up space and has mass, recognize, through experimentation and observation, that matter exists in three forms, including solid, liquid, and gas, and discuss characteristics of each form...
Curated OER
Acid Rain
Students create acid rain using carbonic, nitrous, nitric, and sulfurous acids.
