In this unit, students focus on plants. They begin with an experiment that investigates the science phenomena of how light and water help plants grow from a seed into an adult plant, and then focus on the function of flowers, which produce seeds.](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/how-plants-grow) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/how-plants-grow) [![](https://www.knowatom.com/hubfs/image3-Oct-07-2023-10-43-09-6276-AM.png) ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/flowers) ## [Flowers In this unit, students explore how plants have different parts that help them get what they need to survive from the environment. They begin with experiments that investigate the cause-and-effect relationship between water, light, and the ability of plants to grow. This page is a high-level extract of the second lesson in which students explore flowers. ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/flowers) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/flowers) [![](https://www.knowatom.com/hubfs/insect-anatomy-structure-and-function.jpg) ](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/insect-anatomy-structure-and-function) ## [Insect Anatomy - Structure and Function In this unit, students focus on animals, analyzing how animals’ body parts help them survive and grow. This page is a high-level extract of the first lesson of the unit in which students build insect models to investigate the science phenomena of an insect’s body parts’ structure and function. Students observe how ants use their body parts to get what they need to survive. ](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/insect-anatomy-structure-and-function) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/insect-anatomy-structure-and-function) [![](https://www.knowatom.com/hubfs/bird-beak-structure-and-function.jpg) ](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/bird-beak-structure-and-function) ## [Bird Beak Structure and Function In the last unit, students explored how animals have body parts that help them survive and grow. In this unit, students apply what they have learned about the structures of plants and animals to mimic those structures to solve problems facing people. ](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/bird-beak-structure-and-function) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/bird-beak-structure-and-function) [![](https://www.knowatom.com/hubfs/image3-Oct-07-2023-10-37-09-5416-AM.png) ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/predator-prey-relationships) ## [Predator-Prey Relationships This unit has students exploring animal habitat and predator-prey relationships. Once students model the living and nonliving parts of different habitats, they focus on how living things depend on other living things in their habitat for survival. As a class, students model the predator-prey relationship between foxes and rabbits in a forest habitat, and then dissect owl pellets to analyze a barn owl’s diet.](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/predator-prey-relationships) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/predator-prey-relationships) [![](https://www.knowatom.com/hubfs/image1-Oct-07-2023-10-47-49-4529-AM.png) ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/butterfly-life-cycle) ## [Butterfly Life Cycle In the last unit, students investigated whether plants need light and water to grow, and then explored how flowers have specific structures that help them attract pollinators to make seeds. In this unit, students focus on one kind of pollinator—the butterfly. ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/butterfly-life-cycle) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/butterfly-life-cycle) [![](https://www.knowatom.com/hubfs/image3-Oct-07-2023-10-52-20-1918-AM.png) ](https://www.knowatom.com/science-phenomena-videos/2nd-grade-science/butterfly-structure-and-function) ## [Butterfly Structure and Function In this unit, students continue to learn about living things, focusing on animals. They begin by observing the metamorphosis of a butterfly and then model the parts of a butterfly that help it survive in its environment.
