Fun with Magnets

magnetMy youth group students said they wanted to experiment with magnets, so I wondered what to do and came up with this plan:

 

 

 

 

Materials

  • Magnets (1-2 per student)
  • Paper mazes (1 per student)
  • Paper clips (3 per student)
  • Miscellaneous coins
  • Cereal high in iron
  • Needles (1 per student)
  • Corks or fishing bobbers (1 per student)
  • Plastic cups (1 per student)

Steps – have each student:

  • Navigate the maze with a paperclip using a magnet on the other side of the paper
  • Use the magnet to pick up a paperclip, and have that paperclip pick up another, and so on, to make a chain of paperclips
  • Try to use the magnet to pick up the coins – this should not work
    • This may surprise them, as most people think all magnets pick up all metal objects
  • Try to use the magnet to pick up crushed piles of the cereal high in iron – this should work
    • This may surprise them, as most people don’t think a magnet would pick up cereal
  • Make a compass
    • Stroke a needle with a magnet about 100 times
    • Stick the needle in the cork or fishing bobber
    • You may need to stick a paperclip into the bottom of the cork or fishing bobber to weight it down
    • Put the needle contraption into a cup of water and watch it point north!

 

Fun with Dry Ice

dry-iceAre you looking for an interesting activity to do at your Youth Group or Scout meeting?  One of the best nights we had was with dry ice!  Here’s what we did:

Materials

  • A Block of Dry Ice – keep in a cooler!
  • Gloves
  • Old Silverware
  • Balloons
  • Funnel
  • Bowls for water
  • Candles
  • Paper plates for candles
  • Lighter
  • Cups
  • Soap
  • Paper towels
  • Apple juice

Preparation

Remind the students that dry ice is -109F, so they must wear gloves whenever their hands are even near the dry ice, and they should not touch it!

Activities

1)      Rest silverware against the dry ice to make it sing

2)      Balloons and candles

  1. Put dry ice in balloons and set them in warm water to make them blow up.
  2. Hold the balloon up to their ears – do things sound different?
  3. Light a candle on a paper plate and use the balloon to blow out the candle.

3)      Water and soap

  1. Put dry ice in cup of water
  2. Put dry ice in bowl of soapy water

4)      Put dry ice in cups of apple juice to make it bubbly for students to drink, because it’s always great for them to leave with something fun they made!
