Planning for inquiry reminds me of the proverb: A river needs banks to flow.
Divide your class into groups, and have each group prepare for the activity by mixing food dye into water, pouring the water into an ice cube tray, and freezing it.
Display a globe and have your students observe that all the oceans on Earth are connected to form one "world ocean. Then tell students that they are going to perform an experiment to demonstrate how the colder waters nearer the poles and the warmer waters nearer the equator mix together and move to create ocean currents.
The students in each group should fill a clear baking dish with warm tap water to represent the warm water near the equator. Instruct students to place one ice cube at each end of the baking dish, representing the cold water near the poles.
Invite them to predict what will happen as the ice cubes melt. Students will observe that the cold colored water sinks and moves along the bottom of the baking dish toward the warmer water in the middle; the warmer water moves toward the ends of the baking dish; as the cold water begins to warm, it begins to rise.
Students should record the results of their experiment, accompanying their reports with labeled diagrams and an explanation of how differences in water temperature in different parts of the "world ocean" cause ocean currents. Have students use research materials and the Internet to find out more about ocean currents and how they affect our weather and life on Earth.
Adaptations Adaptations for Older Students: Suggest students read Kon-Tiki by Thor Heyerdahl to find out how the author replicated the voyage that ancient mariners may have made from Peru to Indonesia on primitive balsa rafts, guided only by ocean currents on which they floated.
Explain why the oceans affect Earth's weather. Consider the weather at the equator in comparison to the weather at the poles. How do the oceans affect the weather in your immediate community? How do oceans deal with the large amount of carbon dioxide produced by humans? What are some ideas that scientists have about the ways global warming will affect the oceans?
Should shoreline communities be taking any actions regarding global warming? Discuss why it is important to study ocean currents.
Include in your discussion ways that plants, animals, and humans use ocean currents. Are there historical events that were shaped by ocean currents?

Are there present-day events that have been impacted by ocean currents? All the water on land eventually reaches the ocean. Discuss how the area you live in impacts the environmental quality of the ocean. Can you describe areas that might add toxic material to the ocean?This is an excellent resource for K-3 teachers!

I am a perpetual, quick learner and keen to explore the realm of Data analytics and science. I am deeply excited about the times we live in and the rate at which data is . Getting Started. The film, Hidden Figures, is a fictionalized portrayal of the nonfiction book, also called Hidden Figures, by Margot Lee Shetterly.
The 5 E lesson supports inquire-based instruction. It allows children to make discoveries and to process new skills in an engaging way.
Teachers can also adequately plan power objectives more effectively by using the 5E process. Science and Technology in Action (STA) annually produce a set of industry led lessons, designed to support the teaching of science and related subjects in second level schools.
