How to Make Salt Crystals

Making salt crystals is really easy, though it does take some time, and it’s a great activity to teach kids about evaporation and the formation of crystals. Add it to your water cycle unit or just do it any time you want to do a little kitchen science.

You already have all the materials you need to make salt crystals, and this post from Science Sparks tells you all about how to do it.

You can even make them different colors if you want by adding food coloring.

Head to her blog for all the details and an explanation of how it works.

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.
