Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
In this unit, students continue to explore the phenomena of 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. This page provides an overview of key components of this lesson that has students applying what they know about pollination to design a self-pollinating technology.
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.
In this unit, students figure out phenomena of Earth’s interacting systems, focusing on how the hydrosphere interacts with and is influenced by the other systems. In this lesson, students apply their scientific knowledge of Earth’s water system to engineer water filtration devices to figure out how to reduce the impacts of water pollution on the environment. This page provides an overview of key aspects of this lesson.
In this unit, students use sleds and roller coasters to explore the relationship between energy, forces, and motion. In this lesson, students apply what they know about energy and forces to engineer a roller coaster. This page is a high-level extract of this lesson.
In this unit, students focus on how sound energy is transferred from one place to another in waves. In this engineering lesson, students apply what they have learned about sound energy to design a sound absorbing wall. This page highlights each component of this lesson.
In this unit, students focus on light energy, investigating the science phenomena of how light moves when it interacts with different kinds of matter. Students use scientific knowledge about light to engineer a device that uses mirrors to redirect light. This page is a high-level extract of this lesson.
