Let's Catch Some Dirt From the Air
Students investigate the dirt in the air. In this air quality lesson, students use aluminum foil and petroleum jelly to discover if there is dirt in the air. Students discuss results.
Curated OER
Ocean Pollution & its Effect on Aquatic Animals
Students consider the concept of ocean pollution. In this ocean instructional activity, students participate in a hands-on demonstration in order to replicate an oil spill and its effects on marine life.
Curated OER
Boat Design
Students build a boat and make predictions. In this geometry lesson, students design a cargo boat. They must show that the boat they designed can carry the cargo.
Curated OER
Buoyant Force
Students illustrate Archimedes' Principle of Buoyant Force. In this graphing instructional activity, students will observe that the buoyant force on an object is equal to the weight of the fluid it displaces. Students will then create a...
Curated OER
Condiment Diver
Students create a Cartesian diver out of a bottle of water and a condiment packet (soy sauce, ketchup, etc.) They observe what happens to the packet as they squeeze the bottle and determine which types of condiment packets make the best...
Curated OER
Science: Water States
First graders investigate the various forms of water. They discuss the properties of water. They discover examples of water's various states and locate other solids, liquids, and gases in their homes.
Curated OER
Galapagos Rift Expedition Come On Down!
Students research the development and implementation of a research vessel/vehicle used for deep ocean exploration. In this oceanography lesson plan, students calculate the density of objects by determining the mass and volume.
Curated OER
Water Density and Stability Lab
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.
Curated OER
Froth Flotation
Sixth graders experiment with the froth flotation process to extract metallic ore by using basic chemicals and equipment in the science classroom.
Curated OER
How Dense Are You?
Students examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.
Curated OER
Clay Boats
Seventh graders are given the opportunity to use model-building as a way to help comprehend the forces and phenomena at work in the world around them. They use both successful and unsuccessful models to make inferences, refine...
Curated OER
Separation Before Plastic Recycling
Students participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.
Curated OER
Physical Properties Of Coal
Learners examine and identify the observable properties of coal. After a lecture/demo, students perform a simple experiment. They observe samples of coal and record data in an organized manner.
Curated OER
Let's Catch Some Dirt From the Air
Students create "catchers" that collect dirt particles from the air. They observe the particulate matter that is collected from the air and discuss the effects and causes of air pollution.
Curated OER
Estuarine Currents
Students explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.
Curated OER
Get the Dirt
Students investigate a variety of soil samples placed in cold water jars. Layers of soil are examined for the difference between organic matter and rock fragments.
Curated OER
Wetlands/Watershed Model
Students work together to create a watershed model. They discover the flow of surface water on different topography. They examine how materials originate from miles away and end up in a different wetland.
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...
