Pre-algebra at a ‘Snail’s Pace’

Students in seventh grade pre-algebra spent the morning with snails!

You may have heard an ant can carry something that weighs hundreds of times its own body weight. In pre-algebra, students asked a similar question about snails: How much can a snail pull, relative to its body weight? Each group harnessed a land snail up to a cup, lured it forward with lettuce, and gradually added weight until the snail could no longer pull the cup. They then weighed their snail and how much it was able to pull. Next week, students will use their knowledge of ratio and percent to determine which snail was the “strongest” relative to its body mass, and figure out how much a human could pull if it had equivalent snail-strength! (Eighth grade algebra students also got to take part in the fun!)
