Journal Thread #1 / Prompt 3 - The Guardians
Step into the shoes of a systems engineer and imagine how you would manage an international team working together.
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.
Title of Activity: Journal Thread #1 / Prompt 3 - The Guardians
Brief Description: Students consider the challenge of communicating measurements in a precise way.
Target Grade Level: Grades 8-11
Discipline or Course: Physical Science
Estimated Time Required: 20 minutes
Individual / Partner / Group Work: Individual
- Systems engineer
- Process control
This journal prompt asks students to not only appreciate the differences that can exist in measurement methods, but to think about how communication can improve precision. It asks the student to not only talk about standards of measurement but how to communicate those ideas in a way that diverse listeners (subcontracting engineers) will understand.
The rubric can be modified for student, whole class, or teacher use.
|Constructing Explanations||No explanation of measurement standards||Reference to measurement standards but no specific information||Clear explanation of measurement standards and why they are important|
|Communicating Information||No discussion of communication for precision||Mention of communication for precision without specific guidelines||Specific guidelines for communication to improve precision are included.|
|Identification of arguments based on evidence||No discussion of importance of precision||Precision defined or described without examples||Precision defined with examples|
STUDENT CONTENT BELOW
Mathematics is the language of science and engineering, which depend on measurements being "consistent, accurate, and fair for all… 3,000 languages on Earth," as they say in The Last Artifact. Standardizing measurement makes science and engineering more democratic for all.
Watch the video.
Imagine that you are the systems engineer charged with completing a complex project. Each of the various components of the project are produced in a different country, by manufacturers with different educational, professional, and cultural backgrounds. They have tools made in different ways as well.
You are about to lead your first teleconference meeting with the international team. You want to motivate your subcontractors and establish guidelines to ensure that all of the measurements are consistent. They need to know what standards will be used, how precision will be achieved, and what that will mean for the project.
Develop a succinct presentation. Include background on measurement and how using common standards and procedures will help improve precision. Include tips so that each subcontractor knows how to speak and write in language all the others can understand.
