Description

In this 2-day lesson, students will learn about the features that make Earth a habitable planet. This is mirrored by students learning how we would determine whether an exoplanet is habitable.

On day one, students will be have bell ringers to hook them into the lesson and work through a fill-in-the-blank note with corresponding PowerPoint presentation. The lesson discusses how the following factors are important for a planet's habitability:

- Star Type (so an understanding of the H-R Diagram is preferred)

- Orbital Radius within the Habitable Zone

- Mass of the Planet (for gravity, atmosphere, tectonic activity and magnetosphere)

- Rotation period

- Axial Tilt

- Stabilizing Moon

Wrap up the lesson with the included homework questions or retrieval practice questions.

On day two, after a bell ringer, students will review the requirements for life as we know it to be able to exist on another planet. Confirm student answers using the PowerPoint presentation. Students will then participate in a data analysis assignment. There are 15 data sets labelled A-O. Each data set has information about an exoplanet and its host star. Students will apply the requirements for habitability discussed in class to determine which exoplanet has the highest probability of being habitable. This works best using elimination. For example, F-, G- and K- class stars have the best chance of hosting a habitable exoplanet, so exoplanets orbiting all other star types are eliminated. The students check whether the exoplanet is within the habitable zone. The data is similar to data collected by telescope, with values calculated based on equations and exoplanet names randomized. Note: Some data is beyond our capabilities of collecting right now (e.g. number of moons, axial tilt), but these are included to give students the idea of the process involved. There are follow-up discussion questions for this assignment. All of the 15 data sets include answer keys and there are 3 versions of the corresponding guide for varying levels of assistance.

Student learning goals for the Size of Space Lesson:

  • identify features of Earth that allow it to support life
  • describe which factors we should look for when examining exoplanets for their habitability
  • reason how incredibly small the chance is of a planet being able to support life as we know it

Please examine the images and preview above to see how this resource can help you and your students.

In the zipped file, you will receive:

★ 2-page lesson plan.

★ 33-slide editable PowerPoint presentation with hyperlinks to YouTube videos.

★ 7 pages of student notes that align with the presentation. 4 pages are day one notes, 2 pages of homework questions with room to complete the answers and 1 page of review for day two. Editable Word file and PDF file.

★ Corresponding teacher's notes - already filled in! Great as an accommodation for students with IEPs.

★ 2-page Habitable Planets Data Analysis Guide (x 3 versions for varying levels of assistance)

★ 15-pages of Habitable Planets Data Sets, each with 30 exoplanet's data. There are 2 versions, editable Word and PDF files included. Answer keys using my elimination method are included. If your students create their own guidelines (recommended only for senior level students) their final choices may be slightly different.

★ 21 pages of editable task cards that can be used as formative assessments. 8 pages of quick checks to be used during class and 8 pages of retrieval practice questions to be later in the unit. For ease of use, these are included as all-different on a page, and all-the-same on a page (PDF file and editable PowerPoint file so you can add your own too!).

ALL RESOURCES IN THIS LESSON ARE EDITABLE: The PowerPoint presentation, lesson plans, student and teacher notes, homework, assignment and bell ringers are all editable. File types are Word docx, PowerPoint pptx, and PDF versions are included for each.

This resource is part of my Astronomy all-in-one Lesson Bundle that is supported by (but does NOT include) my Astronomy Doodle Notes Bundle.

If you are interested in using the doodle notes with these lessons your best value is to purchase the Astronomy Growing Bundle. This bundle includes all the lessons, PowerPoints, practice and activities as well as all the doodle notes and anchor charts. This bundle is growing, and all updates are available for free after purchase, simply re-download the zip-file.
