In this sequence of six activities/assessments students plan and conduct investigations to describe and classify objects that will interact with clear soda like raisins, which go up and down. They use their observations (data) as evidence to answer questions about how a variety of objects will interact with soda. Students observe and describe similarities and differences in objects to find patterns and predict how objects will interact with soda.
In the final step, students apply all the skills of inquiry to conduct an investigation. They practice doing systematic observations (a descriptive investigation) by asking a question about an interacting system similar to the soda-raisin interacting system, predicting the outcome, planning the materials and procedure, conducting the investigation, collecting and organizing data, drawing conclusions, giving an explanation or the results, and asking additional questions.
Student recording pages, rubrics for scoring, teaching tips, vocabulary cards, posters for the tools of inquiry, a full investigation booklet, and extensive background information on why and how to teach scientific inquiry for investigations.
NGSS Grade 2-PS-1 Physical Science : Matter and Its Interactions
2-PS-1-1. Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties. [Clarification Statement: Observations could include color, texture, hardness, and flexibility. Patterns could include the similar properties that different materials share.]
This packet would make an excellent half-day teacher training session for NGSS application in second grade classrooms.
