Outdoor Adventures: The Sun by Erin Uda


This week is the spring equinox, where the day and night are almost the same length.  From now on, the days will grow longer than the nights and will keep getting longer until the end of June, when they start slowly getting shorter again. 

Since winter is officially gone, let’s get out and enjoy the bright warm sunshine!

If you’re science-minded and want to talk with your child about the earth’s rotation around the sun and why we have seasons and our days get longer and shorter, use the links and charts below.  I suggest sitting near a bright window in the sun, if you have one, so your child can see and feel the difference between shade and sun.  When you talk about summer, stay in the sun, and when you talk about winter move to a shady part inside and have your child describe the difference he feels in both temperature and light.

Links and charts of the earth’s rotation around the sun: 

Once you’re ready for some outdoor fun, get the following items and head to a sunny spot outside to make a sun dial.

Even better, make your child the sun dial by going outside every hour to draw a circle around her shadow’s head while she stands in the same spot (I recommend drawing a small square where she should stand).  Write the hour inside each circle as you draw them.  


Explain to your child that when the sun shines down on us, a shadow is created where we stop the sun’s rays from reaching the ground.  Shadows are used to tell time, but they’re also useful in the summer when it’s hot, and they’re very fun to step on.  Try making your shadows do crazy things, like shake hands with each other, or not touch your feet.  Outline your shadow with sidewalk chalk and make fun shapes or letters.  Go out at different times of the day and measure the length of your shadow.  When is it the longest?  When is it the shortest? 

Use your shadow (and a flashlight) to make a profile portrait of your child.  If interested, use THIS LINK from Christina Williams that I found on Pinterest to help you make a cool piece of art from your outline.

Try making art using the sun.  Find some solar photo paper (it changes color when exposed to the sun, found HERE) and create a collage out of natural items on it.  Or just place the items on a sheet of colored construction paper and leave it out for at least a couple of hours.  The color will fade on the areas of the paper that were exposed to the sun, while the areas covered with your objects will still be brightly colored.

Talk about the different light that comes from the sun, not just the light and colors that we can see, but also UV rays, which is light we can’t see.  These rays are what make the paper turn color or make certain colors appear to glow.  UV light can be seen by certain animals, and can be seen as a bright glow if you use a black light.  Try some fun projects by going to these LINKS:
And remember, UV rays are also harmful to our skin, which is why we wear sunscreen when we go outside.

When you’re ready to wind down, talk with your child about Stonehenge and the many ancient sites built specifically for keeping track of the sun’s progress through the sky.  Talk about how much work and study (and yes, math) went into making these sites and ask your child what they think.  Go on a photo tour of these places or go to the library and get some books about them.  The study of these places is called Archaeoastronomy.

Because the spring equinox was an important time in the lives of ancient cultures, it was celebrated with many different holidays and festivals, from religious to planting themes.  Look around and see if there are any in your area.
