This interactive resource adapted from the National Park Service describes the different kinds of sediments that make up coastlines, with a focus on the variety in color, size, and sorting.

This interactive resource adapted from the National Park Service describes the many forces that affect shorelines, including tides, weathering, erosion, and deposition.

Students will learn the basic constructs of a video game using the Scratch interface. Students use Scratch to learn about algorithms and event-driven programming. Object-oriented concepts are introduced through the use of sprites and the stage. Students use critical thinking and creativity to complete and enhance Hungry Mouse, a game that they develop using Scratch.

Estimated time required: 2 class periods.

Technology required for this lesson: Design Software, Laptop/Desktop.

In this lesson, students learn how to use computer programming (coding) to control the BBC Micro:bit! They will be able to define computer programming and coding, write their first program for the BBC Micro:bit, and watch their ideas come to life.
