You will need to do this activity in the dark with the lights off. We provide seven different Shadow Patterns, so we recommend setting up seven stations. You can choose to set up fewer stations depending on your space or the number of flashlights that you have available.

Set Up Activity Stations

For each station:

• Cut out one of the paper gnomes. Fold on the solid lines at his feet and the tip of his hat.
• Overlap the flaps at the gnome’s feet and tape him to the rectangle on one of the Shadow Patterns.
• Tape the Shadow Pattern down to a table or desk.
• Put a flashlight beside the gnome.

Find a Sunny Spot (Recommended)

If it’s sunny, you can watch how a shadow cast by the Sun changes over time—just by marking a shadow early in the lesson and checking on it later.

For this extension:

• Cut out one paper gnome. Fold on the solid lines at his feet and the tip of his hat.
• Overlap the flaps at the gnome’s feet and tape him to a blank sheet of paper.
• Tape the blank sheet of paper down to a table or desk that will be in the Sun for the whole time you are teaching the lesson.
• Outline the gnome’s shadow with a marker and write down the time in the center of the outline.

If it’s cloudy when you teach, don’t worry. We show the experiment in the video. You can watch the video and try the experiment yourself on a day when the Sun is out.

We suggest students work in pairs. Homeschool students will need a partner to help them trace their shadow.

You will need access to a playground or other area with a blacktop. This activity works best on a sunny day when students can clearly see their shadows.

Each student will make their own Sun Finder.

Prepare Sun Finder Templates

Fold the Sun Finder template in half, lengthwise. You can fold 5 at a time, if you like.

Put the folded edge in a 3-hole punch and punch the templates. You can work with multiple copies at a time — depending on what your 3-hole punch will accommodate.

It's okay if the hole in the rectangle with the sun on it doesn't quite match the circle printed on the page.

Print a reader for each student to read and staple at the corner. You can choose to print the black and white version for students to color or a version that's already in color.
