Make It! Measure It!
In this Challenge, use what you've learned about metrology to design a new measurement instrument or technique.
Many activities have a teacher view and a student view, and teachers can switch between those views by clicking the blue button in the upper-right. Students will not see this option - only teacher accounts see both views. The teacher view will start with overview text, if available, to frame the activity and get you started. This view will also have teacher tips and suggested answers to student questions spread throughout the activity. The teacher text interleaved with student-facing text will be in italics and should appear as a different color on your screen. Teacher tips are designed to help you deliver a learning experience that is best suited for your classroom.
Whichever view you see on your screen is what will print. You can print this activity without teacher tips by selecting the student view, or print with teacher tips by switching to teacher view. Simply use the standard print function available for your web browser. No extra steps are required.
