Storyline

RALF needs help rebuilding his block masterpiece after it was ruined by someone whose name we will not mention (it was Cobalt).

The crew will use their knowledge of objects to create new blueprints for RALF using the same pieces he used in his original creation. Students will work in teams to analyze the blocks available and present a new idea for something that RALF could build.

3-Dimensional Science

Phenomenon

Objects that are made of small pieces can be taken apart and built into something new.

Science and Engineering Practices

Planning and Carrying Out Investigations

  • Make observations (firsthand or from media) and/or measurements of a proposed object or tool or solution to determine if it solves a problem or meets a goal.

Using Mathematics and Computational Thinking

  • Use quantitative data to compare two alternative solutions to a problem.

Constructing Explanations and Designing Solutions

  • Generate and/or compare multiple solutions to a problem.

Obtaining, Evaluating, and Communicating Information

  • Describe how specific images (e.g., a diagram showing how a machine works) support a scientific or engineering idea.

  • Communicate information or design ideas and/or solutions with others in oral and/or written forms using models, drawings, writing, or numbers that provide detail about scientific ideas, practices, and/or design ideas.

Developing and Using Models

  • Develop a simple model based on evidence to represent a proposed object or tool.

Crosscutting Concepts

Energy and Matter

  • Students observe objects may break into smaller pieces, be put together into larger pieces, or change shapes.

Structure and Function

  • Students observe the shape and stability of structures of natural and designed objects are related to their function(s).

Disciplinary Core Ideas

PS1.A: Structure and Properties of Matter

  • Matter exists as different substances that have observable different properties. Different properties are suited to different purposes. Objects can be built up from smaller parts.
