Curated OER
Stacking Water
Learners experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.
Curated OER
Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. In this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.
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
Investigating Density: Heavy Ice
Learners end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.
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.

Condiment Diver: The World's Simplest Cartesian Diver
Middle schoolers explain what density is in their own words. In this physics lesson, students perform the condiment experiment and explain why some float and some sink. They share their findings in class.

The Letter Ww
Students explore letter Ww. In this letter recognition lesson, students participate in country, state, food, literature, physical education, colors, careers, music, and game activities that are linked to the main lesson page. Students...
Curated OER
Our Ever Changing Earth
First graders discover plate tectonics. They observe the forces of erosion. They observe the forces of weathering. They state three ways the earth changes. They record observations and make conclusions about their observations.
Curated OER
Estuarine Currents
Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.
Curated OER
Matter for Minors
Students use streaming videos, web sites, and hands on activities students to explore matter. They focus on how temperature affects matter and what the particles look like in the states of matter.
Curated OER
Who Sunk the Titanic
Students discuss possible reasons for the Titanic sinking. They are split into small groups to research a historical figure involved in the sinking of the Titanic. They formulate a way to prove their characters guilt or innocence....

Boat Design
Young scholars 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
Inventions 2: The Impact
Students research inventors and inventions and their impacts. In this invention lesson, students research inventions and their affects in good and bad ways.
Curated OER
Wonderful Watermelon Unit
Students get involved in an integrated unit on watermelons. They get knowledgeable about watermelons. This activity involves each student decorating a watermelon and predicting the outcome of it.
Curated OER
Three Methods of Heat Transfer
Learners participate in a variety of experiments designed to illustrate types of heat transfer including conduction, convection and radiation. They complete worksheets as an assessment of the experiments.
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
How Dense Are You?
Young scholars 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
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
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
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.
