Students study the ocean and its characteristics.  In this oceans lesson students complete a lab activity and are able to predict temperature of certain depths. 

Students conduct a series of experiments to study the effects of temperature and salinity on the buoyancy of an object in water. They devise ways to make floating and sinking objects neutrally buoyant.

Students complete a variety of activities using pumpkins. They visit various stations with various pumpkin activities.

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.

Students apply knowledge about density of solids from previous experimentation to this activity which they investigate the density of liquids. They work in small groups to mix water and syrup, and water and oil to see what occurs....

Students examine the relationship between density and buoyancy.  For this physics lesson students use Archimedes' Principle to complete calculations on buoyancy and a lab activity.

Students investigate different liquids to develop their concept of a liquid. They work at a center to tip, swirl, shake, roll, and otherwise investigate seven liquids in small, clear plastic bottles: plain water, corn syrup, liquid...

First graders write about vehicles that float.

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...

Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...

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 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.

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...

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 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 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.

Students examine how salt water is more dense than fresh water through experimentation with eggs.

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.

Learners illustrate Archimedes' Principle of Buoyant Force. In this graphing lesson, students will observe that the buoyant force on an object is equal to the weight of the fluid it displaces. Learners will then create a graph showing...

Learners examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.

Sixth graders investigate the properties of water. In this life science lesson, 6th graders create a concept map of water. They share their work with the class.

An experiment in density where colored water, both hot and cold, are poured into containers of water at room temperature. Students will observe that the warm water rises and the cold water sinks due to their different densities.

In this activity, students will learn about density by determining how to make an egg float in water. By the end of the instructional activity, students will understand that density and weight are different and that density matters in...
