Garden-in-a-baggie

What happens to a seed when you plant it in the soil? They sprout or “Germinate.” In the ground we can’t see the first sprout push out of the seed coat. But!! In this activity, you will be able to see the seed Germinate and grow Roots.  

Materials:

  • Sandwich bag
  • 3-5 Seeds
  • Paper towel & Spray bottle

Procedure:

  1. Get sandwich baggie and write the date on it.
  2. Spray a paper towel with water and fold it in half twice
  3. Put it in the baggie. Paper towel should be damp, but not dripping (too much water could cause mold).
  4. Put the dry seeds on top of the damp paper towel and seal the bag.
  5. Tape the baggie to a window that gets some sunlight. 
  6. The seeds should begin to Germinate in 7-10 days.
  7. Wet the paper towels if it dries out.

Elephant’s Toothpaste

​2. Add 6 teaspoons of warm water and stir for about a minute.
3. Put on your safety glasses.
4. Pour the 1/2 cup of peroxide and dash of Dawn dish detergent into the soda bottle.
5. Stand the bottle with peroxide in the center of the plate. Put the funnel in the opening.
6. Pour the yeast mixture into the bottle and quickly remove the funnel. This may get messy!
7. When it is safe touch the bottle to feel any changes that take place.


Slime

Materials:

– 1 oz. white (Elmer’s) glue
– 3 teaspoons borax dissolved in 8 oz. of water

2. Add 2 spoonfuls of cornstarch into the glue.
3. Stir the glue and corn starch with the spoon. Add food coloring or glitter too!
4. Add 3-4 teaspoons of the borax water to the glue mixture. Wait 15 seconds.
5. Stir the mixture together until it stiffens; mold the putty until it becomes solid. It might take 5- 10
minutes.


Homemade Bubble Solution

Combine in a Bowl:
– 5 cups Water
– 1 tablespoon Glycerin
– 1 cup Dish Soap (Dawn works best)
Stir Ingredients together slowly. Now create your own bubble maker! Pipe cleaners and chop sticks work great!

Balloon Blow-Up

Materials:
• Empty 8 oz. water bottle

Procedure:
1. Fill the water bottle with one inch (approx. 3 oz.) of vinegar.
2. Attach the balloon to the funnel and add 2 spoonfuls of baking soda, remove from funnel
3. Without spilling any of the baking soda, stretch the mouth of the balloon over the mouth of the bottle. Make sure it’s on tight.
4. Put safety glasses on. Turn the balloon completely upright so that the baking soda inside the balloon pours into the bottle with the vinegar. Watch! You created Carbon Dioxide gas!!


CO2 Sandwich

Materials:

  • Sandwich baggie
  • Baking Soda
  • 2 ounces Vinegar
  • 2 ounce soufflé cup
  • Plate
  • Paper towel

Procedure: 

  1. Add 2 spoonfuls of baking soda to the sandwich bag.
