This is a great hands on activity to get students working together and practicing their science process skills. It works great as a review for metric measure or as an activity after lab equipment and metric units have been introduced. Students work in teams to practice estimating, recording and converting metric measurements. At each station there are 2 “Athletes” while the other 2 are the “Officials” who measure and record the data for that event. Each student participates as an athlete in 2 events and as an official in 2 events. The last activity is a whole team activity called mega mind where students convert and compare units of the metric system. This takes about 40 min and my students LOVE this activity!
