Analyze data obtained from testing different materials to determine 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 the last unit, students explored how shelters help animals survive in their environment. In this unit, students investigate the relationship between forces and motion, building propeller cars to observe action-reaction forces, the relationship between the distance their car travels and the amount of force applied, and how friction affects motion.
In this unit, students explore the science phenomenon of how materials can attract or repel other materials without touching them. In this lesson, they investigate how magnets can attract or repel certain objects within their magnetic field. This page highlights the key components of this lesson.
In this unit, students use propeller cars to explore the science phenomena of forces. They investigate action-reaction forces and see if a propeller car travels farther when its rubber band releases a smaller or larger force. Students then explore how friction affects motion by testing how far their car moves after rolling over smooth and rough surfaces.
In the last unit, students used propeller cars to explore the relationship between forces and motion. In this unit, students continue to explore vehicles with a focus on boats and specifically the science phenomena of properties that cause objects such as boats to float or sink.
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.
