In 2nd grade, students conduct investigations, carry out experiments, and apply their scientific knowledge to engineer prototype solutions. In this unit, students investigate the science phenomenon of properties of different kinds of matter, connecting a material’s properties with the functions for which it is used.
In this first unit, students learn to differentiate between the practices of a scientist and those of an engineer. Students ask questions, make observations, and collect data as they explore weather patterns on Earth and investigate how different Earth materials are heated by the sun. During this final lesson of the unit, students act as engineers by designing a prototype that can reduce the warming effects of the sun.
In this unit, students discover that pushes and pulls are forces that change the motion of an object. They begin by exploring how objects move in different directions when they are pushed or pulled, and then investigate how changing the strength of a force changes the distance an object moves. They then use a model to see how friction affects the distance and speed with which an object moves over a surface.
