Comparing the Density of Iron
Learners use scientific measuring tools to collect and use scientific data. They determine the density of four different objects by using their data to explain why objects have similar/different densities even though they are both made...
Curated OER
Distance over Time
Students analyze velocity and how it is determined. They experiment with velocity in order to measure and calculate the magnitude of speed. They use examples in their novel "Skateboard Renegade" to relate velocity to real life situations.
Curated OER
Physical/Chemical Properties of a Burning Candle
Students investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.

Ice Cream Blizzards
Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...
Curated OER
Practice with Mass
Fourth graders investigate the weight/mass of a number of items using grams, and equivalents. They examine the use of a triple beam balance before massing objects including oil and water. They go over the weights they amassed and weigh...

Second graders discover the process of osmosis. In this science lesson plan, 2nd graders learn how different kinds of solutions move through selectively permeable membranes, understand the role of osmosis in the movement of molecules,...
Curated OER
Float Your Boat
Students investigate buoyancy, displacement and density. In this flotation lesson students study the Archimedes' Principle, analyze data and draw conclusions.
Curated OER
The Seeds Tell the Story
Students explore sources of pollution runoff and actions that can be taken to reduce runoff. In this pollution lesson students complete a worksheet and see why bio-essays may provide a more realistic picture of toxicity.
Curated OER
Specific Gravity of Nevada Minerals
Students determine the specific gravity of Nevada minerals by testing them three separate times. They follow specific directions listed in the lesson plan as how to measure the minerals.
Curated OER
Sink or Swim
Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.
Curated OER
Elasticity of Gases
Young scholars investigate gas laws and apply them in experimental conditions. Using an apparatus composed of a syringe and wooden blocks, they experimentally verify Boyle's and Charles' laws of gases.
Curated OER
THe Decomposition of Water
Students collaborate in an experiment where they decompose water into simpler substances through the process of electrolysis. They collect, measure, and observe data and then place the data into a table. Accomodations for students with...
Curated OER
The Same But Different
Fourth graders identify the characteristics of a simple physical change. They describe objects by the properties of the materials from which they are made. Students discuss the different states of matter and their distinct physical...
Curated OER
Red, White, and Blue
Students explore the types of chemical reactions that can be made with household products. Through various inquires, students work to perform chemical reactions using common household substances and cleaners.
Curated OER
Icebergs Ahead!
Students experiment with density of ice, and examine how density affects how icebergs float in water.
Curated OER
Promoting Inquiry Throught Computer-Based Labs
Student Teachers are given the opportunity to examine how to use a computer-based laboratory for inquiry. The practice is done to teach future teachers how to use these tools so they can be ready for use in the classroom environment.
Curated OER
Activity #6 'Nothing' Matters: A Demonstration
Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.
Curated OER
Investigating Porosity and Permeability
Student describe porosity and permeability in sand, gravel, clay and potting soil. They experiment using different materials to discover the different porous substances and the permeability of the same substances. Students place data on...
Curated OER
