Seeing in the Dark

Introduction

Have you ever considered taking a nighttime nature walk? Would you wait until there is a full moon, so you could profit from sunlight reflected on the moon, or would you rather take a flashlight? Do you think trees would look black, green, or grey in the dark? Do this activity to examine your night vision and prepare for your next nighttime adventure!

Materials

• Flashlight that shines white light.
• Flashlight that shines red light. You can also hold a translucent red object like a translucent red food container lid in front of the white flash to make it shine red light.
• Dark room. Almost pitch-black works best. You can also do it outdoors at night, away from street lamps or other sources of light.
• Bag with markers, pencils, and pens of different colors.
• A helper whose eyes you feel comfortable looking into, or a mirror.
