Measurement Challenge—A Density
Super Value Guided-Inquiry Kit
By: Jeff Bracken
Westerville North H.S., Westerville, OH
Give your students a challenge—the measurement challenge! With this innovative kit, students learn to make accurate measurements, estimate to the proper level of certainty, and apply rules for significant figures in calculations. Hands-on, pre-lab measurement activity allows students to begin with length and area, and progress to volume and density—a sequence in which students advance from one-dimensional measure- ments to two- and three-dimensional calculations. Three laboratory experiments serve both introductory and honors science students. First, there is a traditional density experiment—students measure the mass and volume of a block and determine the density. The second lab is a higher-level authentic assessment activity—students are challenged to predict the mass of a block, without the use of a balance! A third optional lab further challenges students as it is a completely open-ended version of the second lab—no hint of a procedure provided. Numerous helpful teaching ideas as well as reproducible student masters are included in the handout. Includes 30 different density blocks—6 different sizes each of 5 types of plastic material. A very worthwhile purchase—use the high-quality blocks for this lab and many other purposes throughout the academic year!
Super Value Kit is complete for 30 students working individually and all materials are reusable—the best one-time purchase you’ll make all year!

How Scientists Measure—
Activity-Stations Kit
By: The Flinn Staff
The ability to make accurate measurements has many applications and is an essential skill for every science laboratory. In this activity-stations lab, students practice measuring mass, length, volume, temperature, and time. Five easy-to-set-up activity stations allow groups of students to work independently as they rotate from one station to the next. Includes detailed instructions with reproducible student handouts and valuable Instructor’s Notes.
Complete for 30 students working in pairs. Standard laboratory equipment such as balances, beakers, and thermometers are required, but not included.
