Each group needs:

• 4 red gumdrops
• 3 green gumdrops
• 3 blue/purple/white gumdrops
• 4-5 wooden toothpicks
• 3 long wooden skewers
• 10 small sticker dots
• Atom Worksheet

Note: Non-sugarcoated gumdrops work better for this activity. If sugarcoated gumdrops are used, students will need to use staples to attach the dot stickers to the gumdrops.
