This auto-grading Google Form uses photographs of shoeprint "evidence" and a large database of collected shoeprints. Students practice recognizing the class and individual characteristics of a shoeprint, and the challenge associate with looking through a database to find an exact match. There are 13 shoeprints as "Evidence" for students, and the "database" holds 54 images of assorted shoeprints, including the matching prints to the evidence and many other distractors. This is an excellent chal

I get to see how well kids remember their metric measurement skills, and they get to do something interactive from the start. This is an activity that has become "famous" in my school, and one that they look

Instead of the boring iodine and starch test (which doesn't get any reaction from students anymore) try this!

Teenagers right now are ALWAYS ready to tell you about their zombie survival plan, or about the zombie video game, TV show, or movie they’ve watched.  I’ve used that theme to introduce or review metric measurement, accuracy, and calculations of percent error.There are 6 activities that students will rotate through in small groups. Each activity asks them to work on a different measurement skill: length, volume, time, and mass. In addition, they'll be asked to calculate their error and percent
