Make a Solar System Out of Pumpkins

November 2, 2023 by Sarah White Leave a Comment

Now that Halloween is over you might be inclined to toss out your pumpkins. But pumpkins are a valid decoration all the way through Thanksgiving, and there are still learning activities you can do with pumpkins (even beyond the classic rotting experiment, which is a great thing to do with your carved pumpkins).

Teach Beside Me shares the idea of using a collection of pumpkins of different sizes to make your own model of the solar system.

This is a great one to do if you have space outside like a driveway or sidewalk where you can draw the orbits for the different planets. If you have a lot of space and want to get fancy you can calculate the relative distance between the planets and the sun and actually measure out a scale model of at least the inner planets (the distances get pretty huge pretty fast). I found a model using a 6-inch sphere for the sun and a building on the Tennessee Tech campus to measure the distances, or you can use the calculator at the Exploratorium to make a model based on the size of your sun. (Of course if you’re just doing it for fun you can alter these distances, for example doing 5.8 inches between the sun and Mercury instead of 5.8 meters as on the Tennessee model.)

Kids can paint and decorate the pumpkins to look more like the planets, and you can use larger pumpkins for larger planets and smaller ones for smaller planets, even if they don’t perfectly fit the model. You can use this time to talk about the characteristics of different planets, and how in your day Pluto was a planet. Draw in the asteroid belt, add the moon, or whatever else you like to make your model.

20 STEAM Educational Gift Ideas For Kids

Celebrate Inventor’s Day by Learning about Inventors

Several countries have a day set aside to honor and recognize their inventors, but Nov. 9 is a special one that’s known as Tag der Erfinder in German. It’s celebrated in Germany, Austria and Switzerland and it falls on Nov. 9 because that’s the birthday of Hedy Lamarr.

Hedy Lamarr is widely known as an actress but there’s a lot more to her story. You can get a little of it geared to little kids in the Little People, Big Dreams book Hedy Lamarr (32 pages, hardcover, published 2023 by Frances Lincoln Childrens Books, suggested retail price $15.99).

The book explores her birth in Austria and how she spent time when she was young coming up with inventions. She became an actress, married an arms dealer, made her escape to America and became an actress again.

But she also helped develop a frequency-hopping signal device for airplanes that was used by the Americans and their allies during World War II. That technology became the basis for wireless technology such as wifi and GPS.

While Inventor’s Day is a great time to learn about Hedy Lamarr, you can take this opportunity to check out books and do little studies on lots of different inventors. If there’s an inventor or an invention your child is particularly interested in, that’s a great place to start. It’s fun to think about all the things we use every day that didn’t always exist; someone had to invent them!

For a start here at Craft Gossip you can learn more about Garrett Morgan, who invented traffic lights; Maria Oroso, who developed a clay oven that could cook food without electricity; and more female inventors and scientists.

And for more general inventors’ fun, check out this inventors word search from Fun Findery (and another from Let’s Do Puzzles) or take a quiz on inventors and their inventions from Flanders Family Home Life.
