Students participate in an experiment about the weight of water. They work together to discover that seawater is more dense than fresh water. They also determine which objects float and sink.

First graders write about vehicles that float.

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...

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...

Young scholars will perform experiments to examine if debris will float, or blow in the wind. They discuss the effects of these characteristics on marine debris.

Students participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

Eighth graders determine the density using mass and volume. For this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...

Students research inventors and inventions and their impacts. In this invention lesson, students research inventions and their affects in good and bad ways.

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.

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.

Sixth graders experiment with the froth flotation process to extract metallic ore by using basic chemicals and equipment in the science classroom.

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...

Learners 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.

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.

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.

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.

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...

Students explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.

In this pumice worksheet, students read about how pumice if formed and the different uses of pumice. Then students complete 4 short answer questions

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.

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.

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.

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...
