  1. STEAM Projects You Can Do Today

    • Water is usually loaded with particles and impurities, which enables ice to form. But purified water isn’t. This allows purified water to reach way colder temperature before solidifying.

      If you leave an unopened bottle of purified water in the freezer for two to three hours, the bottle will be way colder than the freezing point of regular water. When you pour that super-chilled water onto a block of ice, it latches onto the ice’s impurities and freezes instantly!

    • Visual aid of how to complete Dancing Salt
      Dancing Salt

      (Ages 9-16)

      Discover how music creates vibrations you can see using salt and a portable speaker! Then try experimenting with different genres of music to see which ones make the salt dance more.

      What's going on?

      Speakers, like your Bluetooth speaker, produce sound by creating vibrations in the air. Normally, we only hear these vibrations, and we can't easily see them. Plastic wrap, though, is lightweight and thin enough to vibrate in response to the sounds coming from the speakers. These vibrations move through the plastic wrap unevenly, pushing and shoving the salt around in interesting patterns. As a song progresses, these vibrations change, and the salt moves as if it were dancing.

      If you can find a YouTube video of a pure tone (like a single, sustained note), observe what happens to the salt when you play that tone through the speakers. A pure tone will create a consistent, unchanging vibration in the plastic wrap. Instead of dancing around, the salt should collect in places in the plastic wrap that aren't vibrating, making patterns that depend on the frequency of the pure tone. Try a few other pure tones, one at a time, to see some other interesting patterns!

You’ll need to use a low container to make sure the bag rests gently on the ground. That’s it! Your plants will have a steady supply of water to keep them green and growing, without you watering them every day. The self-watering planter takes advantage of capillary action and water’s unique molecular properties. All you need to do is keep an eye on the water level in the bag and refill it when it gets low.
