Curated OER
Science- Unit on Matter- Solids
Second graders identify and describe properties of matter.
They identify three forms of matter- solids, liquids, and gases with 100% accuracy. The student describes the properties of solid objects.
Curated OER
Science: Solids
Second graders investigate the properties of solids and discover how to classify them. Using rulers, they measure various solids on display. In groups, they play an identification game where one students names a location, such as the...

Why is the Ocean Salty?
In this ocean salt worksheet, students read about the processes that have lead to the salt content in the ocean. Then students complete 5 short answer questions.
Curated OER
Buoyant Force
Students investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...
Curated OER
Life in the Ocean
In this ocean worksheet, students review the different life forms that can be found in the ocean and how these organisms are connected to each other. This worksheet has 12 short answer questions.
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
Sink or Swim
Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.
Curated OER
Science: Liquid Matter
Second graders examine the properties of liquids and their classifications. They compare and contrast cups of different liquids and record their findings in journals. Students observe how liquids flow at various speeds and that unlike...
Curated OER
Science: How Solids Become Liquids
Second graders discover how matter changes from one state to another by observing melting ice cubes. They decide on means to warm the ice and predict what will happen. Students record how long it takes for the cubes to melt.
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
(S-1) Sunlight and the Earth
Young scholars discuss the solar heating of the Earth and atmosphere, its heat loss proceses, and the way these relate to weather and climate.
Curated OER
Science-Unit on Matter-Gases
First graders understand that gases take up space even though you can't see or smell it. This is done through many experiments like trapping air in different sized bags, using balloons and plastic bottles, and blowing bubbles. They...
Curated OER
Diving Raisins
Students participate in a mini lab to explore density. In this density lesson students view a demonstration and answer questions.

Bio Ed Online: Gravity and Buoyancy
In the following lesson for grades 6-8, students learn about environments with gravity and those with reduced gravity by observing the behavior of a water-filled plastic bag, both inside and outside of a container of water.
Science Struck
Science Struck: How to Find Volume With Water Displacement Method
Tells the story of how Archimedes discovered the Archimedes Principle and his water displacement method for determining the volume and density of an object. Provides an explanation and several examples of how it is done.
Science Buddies
Science Buddies: Buoyancy of Floating Cylinders
This project presents an interesting puzzle. A disk of wood will float face-up, that is, with its circular cross-section parallel to the surface of the water. A long log of wood, however, floats with the circular cross-section...

Mit: Blossoms: Will an Ice Cube Melt Faster in Freshwater or Saltwater?
Engage young scholars in the study of the ocean and saltwater with these activities. Students will see that saltwater has different physical properties than freshwater - mainly density. This instructional activity can serve as a...
University of California
University of California: Seawater Density & Salinity [Pdf]
Describes the properties of seawater and the variations depending on its location, e.g., near a shoreline, in an estuary, or as sea ice. Discusses the instruments scientists use to measure the density of water and explains other...
