TN COMPONENT OF SCIENCE: Science In Society

TN GOAL:

    To enable students to demonstrate attitudes toward science in solving problems and making personal decisions about issues affecting the individual, society, and the environment.
TN THEME:
    4.5 ECONOMICS - Scientific knowledge should provide a premise for understanding the economic value of applied technology as it relates to society.
TN STANDARD(S): The learner will understand that:
    4.5a Science and technology impact economic growth and productivity.

    BENCHMARK: Advances in science and technology have a direct influence on any society's economic climate.

CLASSROOM CONNECTORS

TIME REQUIRED:

    One hour
MATERIALS:
    Water, salt, cup, spoons, teacher-made activity sheet, globe, pictures of water plants and animals
SET:
    Display a globe. Have students look at the globe and discuss what they see. (mostly water, some land) Today, we are going to talk about the different bodies of water on our earth.
INSTRUCTION:
    A habitat is the place where plants and animals live. Some animals live on land, some live in water. Water habitats can be divided into two categories: salt water and fresh water. Oceans are salt water habitats. (Point out oceans on the globe or map. Discuss) Some animals and plants live in salt water. The salt water contains everything the fish and plants need in order to live. Salt water animals include sharks, crabs, whales, octopus, corals, starfish, eels, and fish. Salt water plants include algae and seaweed. (Show pictures, if available.) Scientist observe the ocean animals and learn about their habitats by new technology such as underwater laboratories.

    Fresh water has no salt. Fresh water can be found in ponds, lakes, rivers, and streams. Fresh water animals and plants cannot survive in salt water. Fresh water animals include snails, sunfish, turtles, snakes, and crayfish. Fresh water plants include cattails, lily pads, grasses, and reeds. (Show pictures, if available.) Scientists take water samples to be sure the water is safe for the fish.

SUPERVISED PRACTICE:
    Change fresh water into salt water. Dissolve salt in water (one spoonful per one-half cup). Stir until the salt disappears. Let each child taste the water. How does it taste? (response) Have children describe. Put the water in a warm place. Leave it for several days until the water evaporates. Taste, then describe. What is left in the cup? (response)
CLOSURE:
    Tell your neighbor the difference between an ocean and a river. Then tell your neighbor why science technology helps our oceans and rivers.
INDEPENDENT PRACTICE:
    (Teacher-made unscramble word activity using the following words: salt freshwater lakes octopus plants ocean streams algae water habitat rivers whales)
