This worksheet is a great opportunity for students to get up and moving as they measure objects around the classroom with a partner. A blank space is left at the bottom for students to measure an object of their choice with their choice of a non-standard unit.
I use this worksheet to have students make predictions of whether they think an object will sink or float. After testing each item by placing it in a bucket of water, students circle the result. A blank space is left at the bottom for students to test out an object of their choice.
