Obtain information and communicate how Minnesota American Indian Tribes and communities and other cultures apply knowledge of the natural world in determining which materials have the properties that are best suited for an intended purpose.
In this unit, students are introduced to scientific exploration as they observe and test the properties of different kinds of matter. For this lesson, students continue their exploration of properties of matter by classifying different kinds of objects according to observable properties.
In the last unit, students observed butterflies moving through their life cycle, explored how butterflies are pollinators, and then designed a hand pollinator. In this unit, students explore the science phenomena of how shelters help animals survive in their environment and then design a prototype burrow-like structure to keep a burrowing owl cool in hot temperatures.
In this unit, students investigate what makes an object float or sink, exploring the science phenomena of properties of objects that float and sink. This page is a high-level extract of the last lesson in 2nd grade that has students applying their knowledge about the relationship between an object’s properties and its ability to float.
