This is a quick and easy I Spy game to get kids thinking and talking about different physical properties of matter. At the most basic, someone pulls a card, and chooses something within eyesight that matches the description. They can give other physical properties clues to get their class/group/partner to guess the item they picked. Play in groups as large or small as you choose, play for 5 minutes or longer, and raise and lower the difficulty by setting the number of cards kids must choose at a time. Each page lists different kinds of physical traits. Print on different colors of paper so if you have kids pick more than one card they cards don’t contradict each other. Keep a pan balance and some graduated cylinders for kids to measure mass and volume as needed.
I'll be introducing it whole group, teaching kids to measure mass and volume and how to estimate and check those things, then playing in small group, then leaving it as an early finisher activity and a 5 minute time filler when I need it. If you come up with something to add or a new way to play, let me know!
Love, Teach Happy
