Summer Crafts for Kids: Week 4 Science

Science has always been my favorite subject and we had trouble picking only a few to do this week for all of you! The kids really enjoy the experiments, we talk about what we think will happen (the hypothesis) and discuss what actually happened and how it differed from what we thought in the beginning.  Fun projects like these really give children a love for learning about science at an early age.  Remember that we did all of these crafts with a 3, 6, and 11 year old and we just altered the amount of parent participation based on the child’s age and skill level.  If you are doing this project with younger children make sure they do not eat any of the materials.

Homemade Silly Putty

The science behind this experiment is: glue in its normal form has molecules that slide past each other easily, giving glue its liquid appearance, when you add the borax it causes the molecules to stick together causing the glue to become rubbery.

What you will need:

  • 1 bottle of glue (Preferred brand: Elmer’s®, you will have to alter the recipe using other brands)photo 4 (4)
  • Borax
  • Water
  • Teaspoon
  • Measuring cup
  • Food coloring
  • Plastic zip top bags

How to:

  1. Pour entire bottle of glue into a mixing bowl
  2. Add warm water to the empty bottle, replace the cap, and shake.
  3. Measure out 1/2 cup of water from the glue bottle
  4. Add a couple drops of food coloring
  5. Add 1 teaspoon of Borax***
  6. Stir until the glue becomes stringy
  7. Use your hands to mix the rest until it is desired consistency.
  8. Store in plastic bag to keep fresh

***We tried Roseart® brand glue too and had to add 2 1/2 teaspoons of Borax.  Other brands may require more or less Borax, the stickier the putty the more Borax you need. For best results use Elmers ®

Rubber Egg

This is a fun project that takes several days to complete.  The egg shell will dissolve but the egg will still be intact. Be aware if you squeeze too hard the egg will bust creating a mess!egg Discard the egg after you finish your experiment.

What you need:

  • Egg
  • Vinegar (regular or apple cider work well)
  • Glass that the egg can fit in
  • Plastic wrap

How to:

Place the egg in the cup and cover with vinegar.  Cover the glass with plastic wrap to prevent your fridge from smelling like vinegar.  Let sit for 2-4 days.  Drain the vinegar, and lightly rinse the egg.


Homemade Slime

This is similar to homemade putty but the consistency is so different! First it falls through your fingers and is really squishy but as you work it, it becomes more of a solid.  Store in a plastic bag when you are not playing with it.

What you need:Slime (6)

  • CLEAR School Glue  (white glue DOES NOT work)
  • Liquid Starch (I had a time trying to find this one, locally Piggly Wiggly carried it)
  • Food Coloring (optional)

How to:

  1. Add equal parts of liquid start and glue (I used 5 ounces, only because the glue comes in a 5 ounce bottle)
  2. Start mixing – we used our hands, it is a ton of fun!
  3. Dump extra liquid from the bowl
  4. Separate in to equal parts and add food coloring (this will stain your hands)
  5. Continue to play! We rolled it out between two pieces of wax paper – shaped it into all sorts of shapes and more!

Explode a Bar of Ivory Soapivory soap photo

What you need:

  • A bar of ivory soap
  • Microwave

How to:

Cut the soap (it has to be ivory) into quarters.  Place on a microwave safe plate and microwave for 1 minute.  Make sure you are watching the soap in the microwave to see the experiment happen.  You can add the fluffy cloud to the bath for continued fun!


How plants drink water

Learn how plants drink water with this science project that visually shows children how the plants work.

What you need: carniation1

  • 6-8 Small vases or glasses
  • 6-8 White Carnations with stems cut to the size of the vases or glasses
  • Food Coloring

How to:

  1. Fill the vases or glasses with water
  2. Add food coloring to the water.  The more food coloring the darker the color.  You can mix the food coloring to create other colors {red+yellow=orange, red+blue=purple, yellow+blue=green}
  3. Add the flowers and watch for changes over a couple days

Magic Dough

What you need:

  • 1/2 cup of salt photo (7)
  • 3/4 cup of baking soda
  • 1/2 cup of cornstarch
  • 1/4 – 1/2 cup of water
  • 1/4 cup flour
  • Vinegar
  • Food coloring (optional)

How to:

  1. Mix the salt, baking soda, and cornstarch together
  2. Add water slowly and stir until thick consistency
  3. Add flour and continue to stir until dough like
  4. Play with the dough
  5. Mix 1/2-1 cup of vinegar with food coloring
  6. Pour over the dough and enjoy!
