3/15/18- Spring Science Experiment: Dissolving Peeps

Okay, I'd admit this science experiment is a little sadistic--it's dissolving Peeps! 😲  What did those poor, cute Peeps ever do to me? Besides be a delicious Easter binge, followed by lots of teeth brushing?  I mean, at least I'm not encouraging you and your children to blow the Peeps up in the microwave.  And truth be told, whether dissolving Peeps or exploding them, it is mad fun science!  Cue mad scientist laugh: baw ha, ha, ha!


Alright, now that that is out of my system, let's dissolve some Peeps!  This experiment is a modified version of ye ol' baking soda and vinegar reaction.

YOU WILL NEED:

A jar
A pan to sit the jar on and another plate to pour baking soda onto
A microwave safe cup/mug that has a handle, preferably a Pyrex measuring cup
A spoon
1/2 cup of baking soda
1 cup of vinegar
1 cup of water
And most important, Peeps

INSTRUCTIONS:

1) Set Up: place a jar inside a pan (the pan will catch overflow liquids) and pour some baking soda onto the plate.  Keep the rest of the baking soda handy.

Set Up

2) On the plate, coat the Peep in baking soda. The natural sweet stickiness of a Peep allows for the baking soda to adhere to it.

3) In the Pyrex measuring cup, pour 1 cup of vinegar and 1 cup of water.  Microwave this mixture until it starts to boil (about 1.5 minutes in the microwave).

4) Carefully, carefully remove (a hot pad to grab the cup's handle might be a good idea) the HOT vinegar/water mixture from the microwave and slowly and carefully pour about half of it into the jar. *Adults, you may want to be in charge of this step since the mixture is HOT.*

5) Drop your baking soda coated peep into the jar.

 Dear Peep, Science Thanks You for Your Sacrifice

6) The classic baking soda and vinegar reaction is taking place.  This reaction will need to be sustained for about 3-4 minutes.  So when the bubbles start to fade, with a spoon, scope some new baking soda into the jar. Then pour a little more HOT vinegar/water mixture (again, *Adults you may want to be in charge of the pouring of HOT liquids*).  Keep alternating between scoping baking soda and pouring vinegar/water until the Peep is dissolved.

Keep Up the Bubbles (Reaction) for 3-4 Minutes

Eeek! Those Are the Peeps Eyes Floating On Top!

Jack's favorite part of this whole mad experiment-- eating the Peeps!  Happy spring time and happy science experimenting!

What You Should Do with Peeps

Bonus Fun: Why Not Throw a Peep into the Microwave and See What Happens?
1) Put the Peep on a plate.
2) Set the microwave to 15 seconds.
3) Watch it expand.

Kaboom! Explosion!  Baw, ha, ha, ha! 

Warning: Peeps were harmed in the making of this science experiment.  All safety lays with the user(s) of the experiment/science experimenter(s).

3/2/17- Spring Break STEM Activity

Spring break is right around the corner for many kids!  Not Jack, as he is in daycare/preschool (which doesn't close for spring break), and he basically just took a week off for a cold. So to preschool for him, and to work for Bobby and me. We'll take him on vacation in late summer/early fall, so don't feel too bad that he doesn't get spring break.

Since spring break is right around the corner, I thought now would be a good time to share another STEM activity.  The activity won't entertain your kids for a whole week (or maybe it could if they end up really liking it), but it is pretty fun.  The professional engineering society that I belong to did the activity at Chase Field's STEM Night, and then we recently did it at E-Day at the AZ Science Center. Not sure if the engineers or kids had more fun.

Without further ado, Galaxy Slime! The slime is so popular right now, check out the MSN video "Slime Fad is Back." I like to think our engineering society started the trend, but most likely we did not.

Supplies Needed:
Bowl
Spoon
1 cup Elmer's Glue (white or clear work)
1 cup Liquid Starch (we used the Walmart brand, Stay-Flo)
Food Coloring (optional)
Glitter (optional)
Plastic Bag (optional)

Instructions:
1) Put the glue into the bowl first.
2) Stir in food coloring and glitter, if desired.
3) Slowly stir in the liquid starch in increments.  You probably won't use the full cup of liquid starch.
4) Stir until you don't see the "white" liquid starch.  Then switch to kneading the slime with your hands, checking how stretchy the slime is.  If you want it stretchy vs.gak, again you probably won't use the full cup of liquid starch.
5) After your child is done playing with their slime, they can save it in a plastic bag (or Tupperware).

Jack's galaxy slime has lasted for a week after he made it at E-Day.  He liked mixing the colors and glitter in the glue, but he lost interest in the final product.  I do think this activity is fun to do with toddlers (who are past the put everything in their mouth stage), just remember toddlers are going to need more help with the food coloring than a 10 year old is (Jack squeezed like 100 drops in because I thought he could do it himself, haha).

It is great for ages 2-99. Thought I'd take the Lego approach there; after 99, you just won't find this activity or Legos fun. Oh, and it's called Galaxy Slime, because if you add color and glitter, it looks like a Galaxy!  Also, the glue and starch combine to make a polymer! Happy (STEM) Spring Break!
