Astronomy Unit Study Resources (with 3 FREE Printables)

Updated: Mar 5

[2023 UPDATES: Now including another hands-on project, "The Earth as a Peppercorn", plus how to use "The Planets" book as a read-aloud "spine" book for older children.] My kids and I have completed several unit studies on Astronomy (4 years apart). My kids and I have a lot of fun with this unit, focusing on:

  • astronomical observations and field trips

  • biographies of famous astronomers

  • hands-on projects

  • general astronomy books

  • astronomy-related movies, music, and documentaries

This combination of resources seems to work particularly well, and really sparks my children's enthusiasm. In this post, I will detail all of the resources and books we have used, to make it easy for you to have your own astronomy unit study, too!

Astronomical Observations and Field Trips

One of the best things about studying astronomy with kids is that some of the field trips can happen in your own back yard. With a little bit of online research, you can find out which astronomical events will be happening over the course of your Astronomy Unit Study. Additionally, you may be able to attend local astronomy events hosted by your local astronomical society or university. Our field trips included:

  • stargazing to find the constellations and planets in our own back yard and while going out for walks after dark

  • getting up in the middle of the night to drive out to a very dark location where we could observe a meteor shower

  • observing a lunar eclipse

  • visiting nearby observatories

  • night sky telescope observations through the local university and astronomical society - this was especially worthwhile because we were able to learn from people who were passionate and knowledgeable about astronomy

A few helpful resources for astronomy field trips are:

  • Earth Sky - This website shows objects of interests for every night.

  • Sky At A Glance - This website has week-by-week information for what to look for in the night sky.

  • Sky and Telescope - This website has detailed lists of upcoming meteor showers, eclipses, comets, and much more.

  • Star Walk app - This app makes it easy to find constellations, stars, and planets of interest, plus other objects of interest such as the International Space Station, satellites, etc.

  • Find the Constellations by H.A. Rey - This book is a perfect first reference for finding the constellations in the sky throughout the year. Beware that, because the planets move throughout the years, older editions of this book may be outdated.

  • The Stars by H.A. Rey - This book gives a more detailed look at the constellations and stars. Beware that, because the planets move throughout the years, older editions of this book may be outdated.

Biographies of Famous Astronomers

With read-aloud biographies, we were able to get up-close and personal with the people who have furthered humanity's understanding of the universe. Biographies are one of the best ways to incorporate history into our learning, as they make the events in history have more meaning when seen within the context of real people's lives.

I have included age codes to make it clear for which ages each book will be best suited. The age codes are: C = Children 4-9; Y = Youth 9-12; YA = Young Adults 13-15; A = Adults and the Later Teen Years (16-18)

Hands-On Projects

We have used a few different simple hands-on projects during our astronomy units. These projects result in visual reminders that we could see daily, so these projects also really helped us become more deeply engaged in learning about astronomy and astronomers.

Paper Model of the Solar System

Creating a paper model of the solar system was a great way for us to understand the sizes of the objects in our solar system. Having this model hanging up in our house for several months resulted in my kids effortlessly learning the order of the planets in the solar system.

We made our solar system model to-scale, meaning that the planets and sun were shown accurately regarding how their sizes compare to each other. The sun really is shockingly large! We hung up each paper planet at the correct distance from the sun so we could see how far apart things are in the solar system; however, we had to use a different scale for the distances from the sun than for the sizes of the planets, or else they would not be able to fit in our home. If we used the same scale for the distance that we used for the size of the planets, Neptune would have needed to be 6,466 feet (over one mile) away from our sun!

Wall of Famous Astronomers

The other simple project we did during our Astronomy unit was the Wall of Famous Astronomers. When we learned about different astronomers, my kids enjoyed cutting and coloring pictures of each astronomer to add to our wall. Having these short biographies and pictures on our wall was very engaging for my kids, as they periodically referred back to the pictures and made up play scenarios involving the different astronomers. The Wall of Famous Astronomers was a helpful visual reminder for us all in learning about each of these important persons.

The Earth as a Peppercorn

Another simple project is The Earth as a Peppercorn, which gives guidance for creating a to-scale model of the solar system with the Earth being represented by a peppercorn. You will need about 1/4 mile of distance to walk for this activity, and it is very impressive to realize just how large the solar system is when you walk out to the gas giants and Pluto!
