In this unit, students are introduced to the science phenomena of landforms on Earth’s surface, exploring how scientists use maps to represent the shapes and kinds of land and water on Earth’s surface.](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/mapping-land-and-water) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/mapping-land-and-water) [![](https://www.knowatom.com/hubfs/image3-Oct-07-2023-10-32-25-3571-AM.png) ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/water-flow) ## [Water Flow In this unit, students explore the phenomena of Earth landforms and the water cycle. Once students have modeled landforms and created maps showing the shapes and kinds of land and bodies of water, students analyze how water moves over the land as it flows downhill because of gravity and cycles between solid and liquid depending on the amount of heat present. ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/water-flow) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/water-flow) [![](https://www.knowatom.com/hubfs/image3-1.png) ](https://www.knowatom.com/science-phenomena-videos/kindergarten-science/the-water-cycle) ## [The Water Cycle This page is a high level extract from lesson 4 where kindergarten students develop a model to show how water is cycled between the Earth’s surface and atmosphere.](https://www.knowatom.com/science-phenomena-videos/kindergarten-science/the-water-cycle) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/kindergarten-science/the-water-cycle) Standards citation: NGSS Lead States. 2013. *Next Generation Science Standards: For States, By State*s.
