      STEM Activities

      stem-freezeoff

      Freeze Off

      Try the Freeze Off Study!

      Foods – or substances made from unique combinations of molecules – have a range of responses to temperature. Discover the different freezing properties of liquids.

      016-compression-squeeze-graphic

      Compression Squeeze

      Try the Compression Squeeze Study!

      Compressors are crucial to a fridge’s ability to help keep food cool and safe. Observe how vapor behaves as built-up pressure releases.

      016-heat-rising-graphic

      Heat Rising

      Try the Heat Rising Study!

      The Law of Thermodynamics is an important aspect of food safety. By keeping food at lower temperatures, it stays safe and breaks down at a much slower rate.

      C016-cupphone-stem-kids

      Cup Phone

      Try the Cup Phone Sound Wave Study!

      Build a telephone with cups and string. Learn how sound can travel through string as long as you stretch it tight.

      C016-blaster-stem-kids

      Blaster

      Try the Blaster Pressure Study!

      Create a ping-pong ball Blaster. Use air pressure to launch your ping-pong ball and see how far it goes!

      C016-spoolracer-stem-kids

      Spool Racer

      Try the Spool Racer Potential and Kinetic Energy Study!

      Build a spool racer. Decorate the spools with supplied racing stickers to customize your racer. Wind up the racer and watch it go! Note that too much winding will cause erratic racer behavior and will take it off course.

      C016-gumdrop-stem-kids

      Gumdrop Bridge

      Try the Gumdrop Bridge Structural Integrity Study!

      Challenge yourself by building a bridge capable of holding a textbook using only candy gumdrops and toothpicks. This activity will require you to think through the engineering aspect of load distribution while also touching on the mathematics of how different shapes affect the strength of a structure.
