February Science Activity

February – 4-H Space Exploration

Will Food Grow in Space? Experiment!

 

Materials Needed

  • Small Sealable Bag (sandwich or snack size)
  • Paper Towel
  • Scissors
  • Water (in a small glass)
  • Marker/Pen
  • Pantry Seeds (Beans, quinoa, popcorn, etc.)

 

Directions

  1. Cut the paper towel twice the size of the bag.
  2. Wad the paper towel and dip it in the water, gently wring it out
  3. Flatten out the wet paper towel, and place 3-5 seeds on the paper towel and fold it in half
  4. Carefully place the paper towel with seeds into the zippered bag and seal
  5. Label the bag with the type of seeds and date.

Mission to Mars Series

The Mars 2020 Perseverance rover, which has started its approach to the Red Planet, will help answer the next logical question in Mars exploration.

With only about 50 million miles (80 million kilometers) left to go in its 293-million-mile (471-million-kilometer) journey, NASA’s Mars 2020 Perseverance rover is nearing its new planetary home. The spacecraft has begun its approach to the Red Planet and in 43 days, on Feb. 18, 2021, Perseverance will blaze through Mars’ atmosphere at about 12,100 mph (19,500 kph), touching down gently on the surface about seven minutes later.

This series will allow 4-Hers to explore some of the subjects and topics surrounding this exciting event.  Youth will learn about related careers, rockets, craters, robots, helicopters and rovers to name a few.  Science, Math, Technology and Engineering principles will be covered in this short, fun, exciting series.  We hope to see you there!

Designed for youth grades 3-6

❄❄Make Your Own Snowglobe           for January❄❄

-Kristin Cook, 4-H Educator
University of Delaware Cooperative Extension

Materials:

Empty Jar with Lid
Water
Glycerin
White Glitter
Small Animals, Toys, Houses, Trees to Decorate

 

❄Glue the toys or other decorations to the inside of the lid, making sure the lid can still fit on the jar.

❄Fill the jar halfway with glycerin, then fill it almost to the top with water, then stir to mix.

❄Add a small amount of glitter. Stir with a spoon to test the ‘snow’ effect, and add more until you get the flurries or blizzard you like.

❄Fill the jar up the rest of the way, until the water is just above the top of the jar.

❄Gently put the lid on and screw it securely to the jar.

❄Wipe any water off the jar, and put some hot glue or tape around the lid.

Enjoy your snow globe!

How does it work?

Glycerin has a very high viscosity. Viscosity is how ‘thick’ a liquid is, how easily it pours. Honey and syrup have pretty high viscosities, water and rubbing alcohol have very low viscosities. Having a mixture of water and glycerin means the liquid inside your snow globe slows the glitter down as gravity pulls it down. This helps it look more like snow.
