Halloween Potions #3...

The Science Mommy is getting into the season with some spooky Halloween potions.  I am not posting pictures, because I don't want to give anything away.  How do your potions turn out?

Ages: Big Kid Scientists

Materials: white glue, laundry starch,  plastic bowl, 2 popsicle sticks, food color

Procedure:

• Mix 1/2 cup of white glue with 1/2 cup laundry starch in a plastic bowl.
• Stir the solution thoroughly.
• Add a few drops of food coloring to make a spooky potion
• Allow the bowl, and the solution, to sit untouched for 5 minutes.
• Knead the mixture for several minutes.
• If your potion is too sticky add a few drops of starch
• You can store this in a plastic bag.

Observations:  Kid Scientists can share their observations of this potion and compare it to the other two.
* How does it feel?  How does it smell?
* Describe the consistency.  Describe the texture.

* Is this a solid or a liquid?  Why?

The Science Mommy would love to see the product of your potions.  Any pictures, with permission, will be shared on the Science Mommy.

Happy Halloween!

Cookie Time...

So, strictly speaking, cookie baking isn't a science project.  However, there were many science skills practiced by these kid scientists.  We also made a huge mess and had lots of fun!

Ages:  All ages of Kid Scientists can participate in the decorating.  Save the baking for the Big Kid scientists.

Materials: A good sugar cookie recipe and ingredients, frosting, food color & sprinkles

Procedure:  

* The Science Mommy has a post coming that is all about measurement.  Baking is one of the best ways for Kid Scientists to learn how to measure...and to experience the consequences of inadequate measurement!  Take advantage of this opportunity to help your Kid Scientists measure.

The Science Mommy wanted today's project to be about the decorating, so the Halloween-themed cookies were already baked when the Kid Scientists assembled.

Universally, Kid Scientists love to mix colors.  Whether they are using paints, or creating their own paints, mixing colors is a great learning opportunity.  The Science Mommy's nieces, Desi and Chloe, were our expert color mixers.

The kids didn't have a limit to the number of colors they could create and we had two shades of green, purple, gray, orange and blue.

While the girls mixed colors, the boys dove into decorating...

 With several dozen cookies and plenty of frosting and sprinkles, there was opportunity to try out every combination...

The finished products were pretty impressive and tasty too!

There are so many opportunities to explore, to create, and to investigate...The Science Mommy challenges you to make a mess and find science in something ordinary!

Crystal Snowflakes...

I posted this activity a while ago without pictures.  Now I have the step-by-step to keep your snowflake hanging in a window.

Ages:  This activity is for Big Kid Scientists.  As you read it, this one sounds more difficult but my 11 year old Kid Scientist did it on his own, I just supervised.

Materials:  pipe cleaner, string, water, borax,wide-mouth jar, food color 

Procedure:

• You will need boiling water for this activity.  Kid Scientists - make sure you have supervision for boiling water

• While you're waiting for the water to boil, create your snowflake.  Cut a pipe cleaner into 3 pieces. Twist the pieces together at the center to form a six-legged shape.  Make sure the snowflake fits into the jar.

• Tie a piece of string to one leg of the snowflake.
• Fill the jar with boiling water

• Add Borax one tablespoon at a time to the water.  Stir after each tablespoon to dissolve the borax.  Stir as much Borax into the water as possible, stopping when the Borax no longer dissolves. (This is called a Saturated Solution)

• Add food color drops to create your favorite color
• Suspend the pipe-cleaner snowflake in the jar of borax solution.  Roll the string around the pencil so that the snowflake hangs from the pencil laid across the jar.  (The snowflake should not touch the jar sides or bottom)

• Allow the jar to sit undisturbed for a day or two before you check your snowflake.

• Now you can take the snowflake out of the jar and carefully hang it up.

The Science Mommy would love to see pictures of your snowflakes!
