In this unit, students focus on the relationship between an organism’s cellular structure and the ability of the organism to access energy to carry out essential life functions. Students begin by examining prokaryotic and eukaryotic cells under the microscope and then compare organelles in plant and animal cells in this lesson. This page is a high-level extract of this lesson.

In this unit, students discover how life reproduces at the cellular level, analyzing the science phenomena of how genetic information is stored in chromosomes. In this lesson, students observe mitosis in plants and animals. This page shows key components of this lesson.
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 discuss the science phenomena of how matter has different properties depending on the number and kind of atoms that make it up. In this lesson, they observe how forces act on matter, focusing on how unbalanced forces cause objects to move. This page provides a high-level extract of this lesson.
In this unit, students expand their understanding of the need for energy among living things to include non living energy systems. They build sleds to figure out how the phenomena of friction transfers energy out of systems. This page highlights components 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.
