What is the name of the type of graph used for comparing salt and fresh water?
"5.ESS2.C.1 Describe and graph the amounts and percentages of salt water and fresh water in various reservoirs to provide evidence about the distribution of water on Earth."
Learning objective:
Salt and fresh water have different properties. Graphs are used to compare properties of salt and fresh water. Variables such as temperature, salinity, and density can be graphed.
Graphing Salt and Fresh Water
Salinity: How much salt is in a body of water. Density: The mass of a substance per volume. Temperature: The measure of hot or cold in a body of water.
Concepts:
Salt water is denser than fresh water. At 4 degrees Celsius, the density of fresh water is the highest. The salinity of the ocean can vary depending on where you measure it.
Fun facts:

Work together in pairs: What is one difference between salt water and fresh water that affects how it can be used?
Brain break: Create a drawing of a creature that is a hybrid of two animals that live in the same environment. Make sure that the creature has features from both animals. For example, the creature could have the wings of a bird and the body of a mammal. Be creative and have fun with it!
