NGSS 2-PS1 Matter and Its Interactions
This series of activities/assessments address NGSS 2-PS1 Matter and Its Interactions:
2-PS1-1. Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
In these activities/assessments, students investigate and classify buttons or other small objects into a binary classification scheme based on the properties of the objects. Then students go to four stations to investigate and classify objects based on the properties of hardness, flexibility, texture, and color. Students record their investigations and classification schemes in a journal which is provided.
Then students use their investigation skills to classify their own collection of objects. Finally, students write an opinion piece about their collections.
Activity/assessment sheets, student journal, rubrics for scoring student work, and teacher background is included.
As an added bonus, a first grade lesson for Science performance and writing is included.
