Description

This module provides grade 2 students with physical sciences core ideas dealing with matter and its interactions and engineering design. Students make and organize observations to find out how solid and liquid materials are similar and different; how the properties of solid and liquid materials determine how they can be used; and how materials can change with changes in temperature.

Students have firsthand experiences to observe, describe, and compare properties of common solids and liquids. They plan and carry out investigations to find out what happens when solids and water are mixed and when liquids and water are mixed. They gain firsthand experience with reversible changes caused by heating or cooling, and then through media expand their data collection. They construct an argument with evidence to support claims about reversible and irreversible changes to materials due to temperature changes.

Students investigate these problems and phenomena:

• A problem to solve 1—Design a model of a tower
• Anchor phenomenon 2—Pouring liquid water and solid water (ice)
• A problem to solve 3—Objects fell in water
• Anchor phenomenon 4—Objects stuck together

Students engage in science and engineering practices to collect data, to answer questions, and to define problems in order to develop solutions. Students gain experiences that will contribute to the understanding of crosscutting concepts of patterns; cause and effect; and energy and matter.
