You may not be able to take a field trip into a deep, dark cave, but you can make a Dark Box that lets students experiment with seeing in dim light and darkness.
Go to the next slide for instructions.
A Dark Box is an opaque box with a hole in one end. Students take turns placing a message inside the box and trying to read the message through the opening. How much light do they need to see the message clearly? Students learn that they can see objects only when light shines on them. See Activity Prep below.
Instead of making Dark Boxes, you can use this distance-friendly substitute activity.
Make the classroom as dark as possible. From their seats, have students read words and signs around the room. Can they read them all? Can they identify the colors of the words?
Turn on the lights. Ask students to read the words and signs. Which words and signs were the easiest to see in the dark? Which were the hardest? Did they get the colors right?
