How Can We Light Our Way in the Dark?

How Can We Light Our Way in the Dark?

How Can We Light Our Way in the Dark? is part of Smithsonian Science for the Classroom, a new curriculum series by the Smithsonian Science Education Center. It is aligned to a group of grade 1 standards. It has a focus on physical science with a secondary focus on life science and engineering design. In this module, students:

  • Investigate interactions between a beam of light and transparent, translucent, and opaque materials, including the formation of shadows and reflection of light
  • Identify cause-and-effect relationships as they explain their observations
  • Obtain information about animal structures that use light to help the animal survive
  • Design a solution that mimics animal structures and increases student visibility in the dark

Below are digital resources that support teaching of this module.

Module Overview

This file contains the blackline masters for the module, including notebook sheets and activity sheets.

Lesson 1: It’s Dark in Here

Caves
Download PDF
These photos of cave exteriors and interiors serve as an introduction to caves and give students the opportunity to practice making observations.

Cave Objects
Download PDF
The file contains images of the objects students will investigate in the Light Up the Cave simulation.

Cave Simulation Directions
Download PDF
The file provides directions for students prior to and during the computer simulation.

Light Up the Cave
Play simulation
The Light Up the Cave simulation is available as a website for computers. Download the application for use on tablets or mobile devices.

This simulation gives students an opportunity to investigate light sources in a dark environment.

Students can move objects one at a time into the cave to see if they provide light. They can click an object on the right to activate it. It will then follow their cursor movement. Students can release the object by clicking a second time. Once students have investigated the object, they should place it along the left side of the screen, ordering the objects based on how well they would help the student find something in the cave. Objects can be reordered. The students’ final ordering will show on the screen once students select Done.
