To determine the purpose of units in science, students will identify and compare the units used for common outer space measurements with units typically used for Earth measurements. Then, students will think about the importance of using standard units versus relative values when describing data before creating a scaled drawing of exoplanet distances.

In this guide, students will learn how scientists used molecular biology to rethink a popular mathematical formula for finding a dog’s age in human years. Students will then analyze and discuss mathematical models.

Students will define, apply and analyze a new mathematical model for determining dog age in human years before comparing it to an old version of the model. Then, students will give examples of mathematical models in other fields and think about models’ benefits and limitations.

Students will answer questions about the online Science News article “Calculating a dog’s age in human years is harder than you think,” which explores how scientists used molecular biology to more accurately compare canine aging with human aging. A version of the story, “Calculating a dog’s age requires a bit more math,” can be found in the August 15, 2020 issue of Science News.

Students will practice analyzing and graphing data about the moon’s orbit. The activity will help students understand the Earth-moon system and the nature of elliptical orbits.

After watching a video about transistors, your class can use these discussion prompts to analyze transistor technology and predict future trends in computer processing.

Students will practice analyzing and graphing data using two data tables from a primary research study about space dust.

Students will learn how interactions among the protons and neutrons in the atomic nucleus affect the properties and stability of chemical elements, and how these properties could inform the creation of future elements.

Students will use what they know about physics and human range of motion to analyze classmates’ trackways and infer how their classmates made the tracks.

Students will come up with a Jeopardy! style game or use a game provided to better understand the character traits, personality qualities and career paths of the SN 10: Scientists to Watch.

Students will define key science terms from a range of scientific fields using contextual clues from Science News articles.

This guide covers experimental design, social science surveys, statistics and the importance of reproducible results.
