Setting Up Your High School Astronomy Curriculum

December 8, 2021 /

I’ve had a lifelong passion for Astronomy. I was extremely fortunate that in my third year teaching, I was able to petition my school to add an Astronomy course to our curriculum offerings. The challenge, though, was setting up a high school Astronomy curriculum from scratch. I previously wrote about my top resources for teaching Astronomy, but let’s take a look at the basics. What should you teach in a high school Astronomy course?

Well, that might depend on your district/state standards. My state does have standards for Astronomy, but they are mostly Physics or general science standards. However, this meant I had a lot of flexibility in what to teach and how to organize my course.

My school is a daily 50 minute period. We marketed Astronomy to primarily seniors, so I had approximately 8 weeks of instruction in quarters 1-3 and 6 weeks in quarter 4.

Quarter 1 – Observational Astronomy

I begin my high school Astronomy curriculum with some basics of Astronomy and focusing on what we can observe in the night sky. As my state standards are based on Physics standards, we hit a lot of the motion and Kepler’s/Newton’s laws standards here in the first quarter. For instance, I invested in some simple Galileoscopes to have students practice building a telescope and use them outside. Also, check out my lesson plan and activity on the Moon phases I use in this unit.

We typically spend 1-2 days practicing using the telescopes in the daytime and recording what we can observe just around the school courtyard. Since this is in the fall/winter and sunrise isn’t usually until after school starts, we also typically have at least a week of before-school observations. As a result, the timing is perfect to usually observe some major known constellations and the Orion Nebula, Pleiades, and other easy-to-find celestial objects.

  • The Night Sky
    • Celestial sphere, constellations, orbital motion, moon phases, eclipses

  • History of Astronomy
    • Ancient astronomy, Copernicus and Galileo, Brahe and Kepler, Newton

  • Light and Telescopes
    • Early telescopes, light and electromagnetic spectrum, practice using telescopes, space telescopes

Quarter 2 – The Solar System

Here we focus on all aspects of the solar system, starting with the solar system as a whole, then Earth, then each group of planets. I try to focus on comparative planetology – comparing the planets and their properties to each other, rather than memorizing facts about each planet.

Here is a sample data sheet I have used to help students organize their notes about each planet.

For the Jovian planets, I also like to include some information about the major moons. We typically discuss the Galilean moons, along with Titan, Enceladus, and Triton (sorry, Uranus).

  • The Solar System and Earth
    • Layout of the solar system, solar nebular theory, Earth as a planet, Earth’s interior and atmosphere

  • Terrestrial Planets
    • Moon and Mercury: comparisons, surfaces, atmospheres; Venus: greenhouse effect, volcanism, atmosphere, interior; Mars: atmosphere, interior, volcanism, missions and rovers

  • Jovian Planets
    • Jupiter and Saturn: comparisons, atmospheres, interiors, missions, major moons; Uranus and Saturn: comparisons, atmospheres, interiors, missions, major moons

  • Beyond Planets
    • asteroid belt, Kuiper belt, Oort Cloud, major asteroids and dwarf planets

Quarter 3 – Stars

Stars are definitely my favorite topic, and it is also usually a big hit with students. We spend a lot of time on the different life cycles. First, we look at the Sun and its properties as a star. In the low mass stars section, we focus on stars that end as white dwarfs. I typically spend the most time in the high mass stars section, as nuclear fusion, supernovae, and black holes tend to be high-interest areas.

Real questions from students about black holes. I always try to dedicate 2-3 days to a black holes research project as its a high-interest topic.

We usually wrap up this quarter with galaxies, though time-dependent I have moved it to quarter 4.

  • The Sun as a Star
    • Sun surface, interior, properties, sunspots

  • Low Mass Stars
    • Red dwarf and Sun-like main sequence stars, Sun-like star life cycle

  • High Mass Stars
    • High mass main sequence, supernovae, black holes

  • Galaxies
    • Galaxy types, galaxy classification, Milky Way galaxy properties

Quarter 4 – Cosmology and Spaceflight

Cosmology is the outlier here, but it fits where it fits, especially as we have just studied galaxies. We focus on the history of Cosmology and how the model of the Universe has changed over time.

As I am based in Florida, we have A LOT of state standards related to the space program. As a result, I decided to end the year with this as we wind down the year by building bottle rockets. The history of human spaceflight is a topic I am very passionate about and it’s a little less rigorous, so it’s a great way to send off the year. We focus on the different eras of the US Space Program and the major achievements of each.

  • Cosmology
    • Expansion of the Universe, Big Bang, eras of the early Universe, Universe models

  • Rocketry
    • Principles of rocketry, aerodynamics, Newton’s laws revisited, building a rocket

  • Human Spaceflight
    • Early spaceflight, projects Mercury and Gemini, project Apollo, Space Shuttle and beyond

Building your high school Astronomy curriculum

I hope this breakdown is helpful as you build your own high school Astronomy curriculum. Depending on your state and standards you may have different focus areas, but these are the major topics any Astronomy course should address.

High School Astronomy Ideas – Less Lecture, More Engagement!

April 29, 2020 /

I’ve talked in previous posts about my hatred of lecturing. I end up doing all the work, while students sit passively. Sure, there are ways to make lectures more engaging. However, I discovered with a particularly challenging Astronomy class last year that lectures simply weren’t working. I stopped lecturing. I stopped pretty much all teacher-led instruction. What did I do instead? I created student-led, student-centered activities. I posted about student-centered instruction before, but now I want to share how I did it in my Astronomy class. Here are five high school Astronomy ideas, along with example lessons you can use in your Astronomy class.

Gallery Walks

Astronomy is definitely a very visually important subject. Looking at photographs is a major part of my class. However, instead of looking at pictures as a class and discussing them, break the discussions into smaller groups with a gallery walk. I call these Astronomy Art Galleries. They are one of my favorite and most engaging high school Astronomy ideas. I have done them virtually with Google Slides/PowerPoint and with physical pictures around the classroom.

Here is my Galaxy Gallery assignment I used this school year. Click here for my full lesson plan. This activity was done with laptops (one laptop per group of 3-4 students)

Here are some easy topics to create your own Astronomy Art Gallery:

Station Rotations

Station rotations are not only engaging but a great way to cover a lot of content in a short amount of time. I tend to do four stations in a 50 minute class period (~7-8 minutes per station). There are eight total groups in my classroom, so I do mirrored stations.

I usually have at least one station where students are using a laptop or phone. Some types of stations you can include are:

  • Watching a short video
  • Playing a Quizlet game
  • Coloring/labeling a diagram
  • Using question dice
  • Reviewing work with the teacher
  • Reading a news article
  • Completing practice questions/problems
One of my favorite high school Astronomy ideas is to incorporate station rotations - get those kids moving!
Here is a brief station overview of an activity I did on the terrestrial planets. Click here for the more in-depth station directions.

I like to have one station with new information, one with review information, one with a video, and one with a group discussion. That’s not a perfect, works-in-every-lesson formula, but it is my skeleton I start with!

Questioning and Research

Students tend to be interested in Astronomy, even if they aren’t always engaged with every lesson. I like to give them the opportunity to ask questions. Then, we structure a research activity based on their research.

For this lesson on black holes, I asked students to write something they want to know about black holes. I used the Nearpod Collaborate tool so I could see who wrote what, but it was anonymous to other students. The next day, I brought out every book I own that mentions black holes, along with laptops. Students were tasked with trying to answer some of the questions they asked. The culminating assignment was to write a news article about black holes.

Simulations and Virtual Labs

Labs in Astronomy can be difficult, but there are many you can do. However, I often use simulations and virtual labs to do what we can’t in class. I’ve talked about PhET simulations many, many times, but a lot of teachers don’t know that they have a lot more than just Physics!

This PhET simulation on blackbody radiation is a great way to introduce stars!
I use this simulation from PhET to introduce the H-R Diagram and different types of stars. Here is a sample worksheet to go along with it.

Some of the more Astronomy appropriate simulations PhET has are:

In addition to PhET, I have also used simulations from UNL, eduMedia, Stellarium, and Celestia.

News Articles

I feel like every single day I find a news article about something we are learning about in Astronomy. There is always new information and celestial events going on! I use news articles all the time in my classroom. This is another one of the most engaging high school Astronomy ideas!

For example, I found a news article about Mars One, and another describing why it won’t work. Students read those two articles and debated whether we should go to Mars. Here is the lesson plan for that activity.

Some other topics you could use news articles with are:

  • Comparing types of supernovae
  • Exoplanets
  • Meteor showers and what causes them
  • Types of eclipses
  • Discoveries from probes such as Juno and New Horizons

I hope these ideas have inspired you to rethink your classroom!
