Scientists in Training

Bring the youngest scientific imaginations alive with these at home science activities!

Volcanic Snow

Materials:
  • 2 heaping tablespoons baking soda
  • 1 tablespoon dish soap
  • Food coloring of your choosing
  • 30 ml vinegar
  • Snow
  • Small plastic cup
Directions:
  1. Place the plastic cup on the ground.
  2. Pack snow tightly around the cup, making sure to keep the top open.
  3. Pour all ingredients down into the cup, except for the vinegar.
  4. When you’re ready for your volcano to start erupting, pour in the vinegar.
  5. Step back and watch your volcano come alive!
 

Freeze a Bubble!

Materials:
  • 6 cups of water
  • 1 cup Karo corn syrup
  • 2 cups clear dishwashing soap
  • 1 large bowl
  • 1 shallow container
  • 1 straw
Directions:
  1. In a large bowl, gently stir together water and Karo without making bubbles.
  2. Add soap, mixing well.
  3. Pour some of the mixture into a shallow container.
  4. Dip a bubble wand in and blow!
  5. Alternately, you could use a typical bubble wand instead of the straw.
 

Make Your Pennies Shine

Materials:
  • Lemon juice
  • Tarnished pennies
  • A cup
  • Paper towels
Directions:
  1. Place a dirty penny in the cup, covering it with lemon juice.
  2. After five minutes, remove the penny and wipe it clean with the paper towel.
 

Use “Invisible Ink” to write a secret message!

Materials:
  • Paper
  • Cup
  • Cotton swab
  • Some type of heat source, such as a lamp or blow-dryer
  • Milk or lemon juice… or both!
Directions:
  1. Squeeze lemon juice into a small amount of water or pour milk in a cup.
  2. Stick the end of the cotton swab in the liquid.
  3. Use the soaked cotton swab to write your message.
  4. Let your message dry completely.
  5. With an adult’s assistance, hold the paper near a light source. This will illuminate your secret message, just like magic!
 

Pepper and Soap “Germ” Activity

Materials:
  • A shallow dish, such as a pie plate
  • Water
  • Black pepper
  • Liquid dish soap.
Directions:
  1. Fill shallow dish halfway with water.
  2. Sprinkle black pepper on the surface of the water, noting that the water’s surface tension will keep the pepper flakes afloat.
  3. Dip your finger into the center of the dish, observing what happens (not much).
  4. Now imagine with your scientist in training, that the pepper flakes are “germs”.
  5. Place the tip of one finger into the dish soap—only a little is needed.
  6. Dip the soapy finger into the pepper water and watch as the pepper flakes scatter to the edges of the plate.
  7. Discuss with your scientist in training how the soap is specially formulated to disrupt the surface tension, making it effective on greasy, dirty dishes and chasing "germs" away!
