Autumn Equinox

Autumn· Geography· Math in Nature· Meteorology

15 Mar

The Autumn Equinox is a time where the length of our day is equal to the length of our night. The days are becoming shorter, and at the equinox, the length of day will be 12hrs and the length of night will be 12hrs (approximately). After the equinox, the days will continue to become shorter until we get to the shortest day of the year called the winter solstice.

Come and learn some MATH WORDS while we discover more about the Autumn Equinox!

This is our earth. It is a SPHERE.

We divide our Earth into two parts, called HEMISPHERES, the Northern Hemisphere and the Southern Hemisphere. The line that divides them is called the Equator. Australia is in the Southern Hemisphere.

Our Earth spins on its AXIS which is an imaginary line. You can see how this works by taking an orange and putting a skewer through the middle. Like this, the orange will spin around the ‘skewer’ axis.

When the Earth faces the sun, we have day, when it faces away from the sun, we have night. Because the axis of the earth is at an angle to the sun, the length of day and night changes depending on where the Earth is in its orbit.

Each year, as the earth travels its orbit, and we have two occasions where the length of day is EQUAL to the length of night; the Autumn Equinox and the Spring (or Vernal) Equinox. Equinox is the Latin word for ‘equal night.’ The day is approximately 12 hours and the night is also approximately 12 hours.

The Autumn Equinox occurs when the rays of the sun strike PERPENDICULAR to the surface of the earth at the equator, then the earth has an equal amount of daylight hours and night-time hours.

You might like to watch this video which explains the equinox.

I have made this Autumn Equinox poster for you. You may like to download it and display it as the Autumn Equinox draws near.

Hey Explorer

We have outdoor expeditions to undertake and adventures to embark upon. We’ll explore the outdoors together, side by side, and uncover miraculous mysteries, and secrets. We’ll wander, and wonder in amazement as we become familiar with the Australian fauna and flora.

I desire to come alongside you in the muddle, making nature study the joy it’s meant to be.  Outdoor adventures will become a regular part of your life as you make connections to the natural world with a sense of awe.

I looked high and low online for an Australian nature based curriculum and when I found Australian Nature study Guide on Instagram I was so excited to have finally found something that my family can relate to. My favourite thing about this guide is that Marie is so hands on and involved with her customers. I have never felt alone in the journey, she is there to guide and encourage us every step of the way in the Facebook group. Thanks Marie for welcoming us to your nature study family 🙂

We began our homeschool journey this year keen to explore all that nature study entails. I had searched the web for weeks to research what we would use as our framework. I cannot describe the elation I felt when I came across an AUSTRALIAN nature study guide! Marie has done all the hard work and put together a wonderfully elaborate resource for all ages. You can dip your toe in or dive right into all the ideas and links. There’s so much here we could spend all week doing nature study, and often we do.

We have really enjoyed the program this term. We have gotten outside more often and the children are definitely taking more notice of things when we are out. Having a place to share what we have done and seen has been an encouragement to keep it up. I sometimes felt like we could spend longer on some topics as they were so interesting but that is probably just my obsessive "we must cover everything now" problem.

We didn’t find out about the program until about half way through term, so we played catch up most of the time. I love how open ended the lessons are, but with enough structure to work well for those children needing such a program. We have been able to cover much of the required curriculum whilst enjoying the activities we love. Your program has been such a blessing to us, because we needed a change to our homeschooling lessons which would still cover curriculum, but would enable us to relax and enjoy “school” together. Thank you.
