2.LS3.1

In this unit, students discover living things, beginning with an investigation into the differences between living and nonliving things. Students then explore how water helps plants grow and develop the structures they need to survive.

In the last unit, students analyzed how engineers can mimic plant and animal structures to solve problems facing people. In this unit, students begin by exploring animal behaviors of parents and offspring that help the offspring survive.

In this unit, students are introduced to living things on Earth. They begin by exploring the differences between living and nonliving things and then investigate what plants and animals need to survive by watching bean plants grow and observing a cricket in its habitat. They then create a model to show how living things depend on other living things and their environment to survive, and can change their environment to help them get what they need.

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.
