Journal Thread #1 / Prompt 5 - Why Does It Matter?
Step into the shoes of a researcher and consider how the opportunity to use standards based on universal constants could expand and deepen your investigations, making previous discoveries even more profound.
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 5 - Why Does It Matter?
Brief Description: Students reflect on the potential of new standards to enhance innovation.
Target Grade Level: Grades 8-12
Discipline or Course: Physical Science
Estimated Time Required: One 45-minute session in combination with video segment from The Last Artifact
Individual / Partner / Group Work: Individual
Expect students to reflect in three different ways:
- First, students should be able to identify a specific measurement and constant use as standards for the research they choose.
- Students should indicate a recognition that accuracy of the measurements increases with the new standards.
- Students may recognize that the repeated research will either a) increase the ability of the researchers to communicate information with research partners, or the potential to coordinate with future research projects because the standard is a constant.
|Identifying measurements and constants||Response lacks an identification of a specific measurement and constant||Response includes a mention of a measurement but not the constant used now as a standard||Response includes mention of a measurement and a constant|
|Recognition of importance of constants||No clear discussion of accuracy, or confusion with precision.||Vague or inconsistent mention of accuracy or precision.||Clear explanation of the importance of constants in increasing accuracy and the potential for better measurements|
|Importance of constants in research||No description of how the research would now be different.||Description of differences in research protocols, not clearly related to accuracy.||Clear explanation of how the new standards would improve either communication or future research.|

Watch the segment from The Last Artifact.
Now that you’ve followed the progress of metrology over the last decade, you have a deeper understanding of how this science supports research and innovation.
Imagine you are a researcher in one of the following fields. A decade ago you completed a research with some significant results. But like most research efforts, it also left interesting new questions.
Now you have the opportunity to repeat your research. Think about how it would be different now that you have the opportunity to use standards based on universal constants. Will it be more accurate? Will it provide more statistically significant results? Will it open up even more interesting questions?
While your old research was done in your own lab, you are now proposing to work with two other teams in different countries.
Write two paragraphs of your application for new grant funding:
It will be important to repeat the research because…
New measurement standards will increase the potential of this research to…
