Today’s the Day!
If you’ve been growing sunflowers with us as part of the Compton Hospice Sunflower Challenge you need to measure your sunflowers today. There are fabulous prizes on offer for the tallest bloom, so measure up and contact Compton with your vital statistics.
Our tallest is currently 1m 65cm. They got up to 2m 47cm last year, so there’s plenty more growing to be done. How tall are yours?
If you’ve been enjoying growing sunflowers (whether you’re joining in the official challenge or not) and have a sunflower-themed play idea to share with us – we would love to see them. Please add a link to the Linky at the end of this post. We’ve shared some ideas for art, science and math in our Sunflower Activities ebook, and here’s one more idea for sunflower fun.
How to make a Sunflower sundial
Sunflowers love sunshine of course and grow best when they’re in full sun (challenge contenders take note!), so why not combine the two with a dash of horology science to make a sunflower sundial.
Materials: a stick, a flowerpot filled with soil (or something else to hold the stick upright), a clock timer, yellow chalk, a patio / driveway /yard and sunshine!
Place your stick in the flowerpot, so it stands upright and then place the pot in a part of the patio or yard which gets the sun all day.
This stick will be the gnomon (good word!) which is going to cast a shadow on your dial, and you’ll use the yellow chalk to draw sunflower petals on the floor to mark out each hour of the day. We made our clock from 8am to 8pm
At 8 o’clock use your chalk to draw a petal on the ground, with the tip of the petal marking where the shadow of the gnomon falls. Add a number 8 to the tip of the petal.
Set your clock timer for 9 o’clock. When the alarm goes off, it’s time to mark out the location of the 9 o’clock petal. Continue setting the timer and marking off your petals throughout the day.
You could try out some the the ideas in our Sunflower Activities ebook or from the linky below to help you pass the time. We had lots of excited shrieks when the alarm rang!
Talk with the children about what’s happening with your sun clock. Why do the shadows move? Why are the shadows longer sometimes and shorter at other times? Do they think the pattern is different each day or the same?
