Curated OER
Water Displacement
Students formulate a hypothesis using critical thinking skills. They use an orange to examine the displacement of water as the orange sinks or floats.
Curated OER
Graphical Determination of Density
Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.
Curated OER
The Buoyancy Factor
Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...
Curated OER
Inventions 2: The Impact
Learners research inventors and inventions and their impacts. In this invention lesson plan, students research inventions and their affects in good and bad ways.
Curated OER
Trash Traits: Marine Debris, Litter, Ecology, Oceans
Students perform experiments to examine whether trash can float, blow around, or wash away. The effects of these characteristics on the presence of marine debris in the environment are then discussed.
Curated OER
Marine Debris
Students will perform experiments to examine if debris will float, or blow in the wind. They discuss the effects of these characteristics on marine debris.
Curated OER
Volumw Measurement, English System
Eighth graders biew each volume container and discuss where they have seen them in their home, and how they have seen them used. They explore the different names of volume sizes and their equivalents towards one another. Students...
Curated OER
Uses of Pumice
For 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
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
Activity #16 Dancing Spagehetti
Students experiment with floating the spaghetti, the gas functions like a life preserver. Pupils comprehend that a person is slightly more dense than water. They comprehend that a life preservers are made of low-density materials. The...
Curated OER
Introduction to Density
Seventh graders define density in their own words. In this physics lesson, 7th graders solve density problems using its mathematical formula. They explain why some objects flow and some sink.
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
Investigating Density: Heavy Ice
Students end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.
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
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
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, students calculate the density of objects by determining the mass and volume.
Curated OER
Get the Dirt
Learners 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
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
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.
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
Students 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
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...
