Science Sunday!

In my former life (pre kids, that is!) I was a preschool teacher.  And a pretty darn good one, if I can pat myself on the back a little here.  But at home, with my own kid, I'm finding a hard time getting in the groove.  Raina's almost 3 now (2 weeks!), so technically, she's a preschooler.  (Wait, what?!  How'd she get that old??)  I've been wishing for a while now that I could get my behind in gear and really start trying to get some learnin' in at home in semi-structured sort of way.  We're (sorta) getting the hang of this 2 kids thing, so I'm starting slowly, and seeing how things go.

Today was Science Sunday.

And it rocked.

Hearing Raina yell, "Let's do more science!" is pretty awesome.

We did 4 experiments:
(you can watch videos of the first three of these on you tube if you want more details!)

Milk, food coloring, and dish soap

In a shallow dish (we used a plastic lid), pour a layer of milk.  We used whole milk.  I wonder if the fat content makes a difference in how the effect comes across?

Drip food coloring into the center of the milk.  Don't worry if it looks like they are mixing together.

Squirt a drop or two of dish soap into the center.... and watch the colors dance!

Raina thought this one was pretty incredible.  We did it a bunch of times, varying the colors, food coloring placement, amounts of each ingredient, etc.  We also did some investigations like "What happens if we blow on it?

 If we blow on it with a straw?"

"What hapens when we tip the plate?"  "What happens when we stir the mixture?"

Volcano pre-show:  how does it work?

I wanted to do volcanoes.  But inside the volcano, the workings of this get hidden! So we did it first in little clear containers.  Raina squirted in three different colors...

then mixed in baking soda...

then poured in vinegar!

We got science ALL over the floor!  And on Lucca's pants.  I wonder if Lucca learned any science by being an observer today?  :)

After the fizzing and bubbling subsided, she spent some time mixing the lava bowls to make new colors!


We decided to make our volcano out of playdoh.  Raina was concerned when I told her it would ruin the playdoh, but I assured her we'd get more, and then she was okay with it.

We made a big hole...

Jammed in some baking soda (we are now officially out of baking soda!)...

Put a few drops of food coloring and some vinegar in a cup...

and poured it in for an explosion!!

We made a yellow explosion next, and then added some dish soap to mix things up.  Dish soap makes the explosion BUBBLY!  Cool!

Sharpie tie-dye

I saw this idea on Pinterest.  All over Pinterest, actually.  You use sharpies to decorate some white fabric (we used a white mens tshirt stretched over a baking sheet, and held it in place with rubber bands).

We did it on our couch, but you might not want to :).  Our couch is yuck, to be truthful, and I don't mind getting things on it anymore.  Any excuse to get rid of it.

When it's decorated to your liking, spray it with a spray bottle filled with rubbing alcohol.  The colors will start to run and spread!  The more you soak it, the more they spread.

For this step, we set up in the tub.  Make sure to ventilate! (Our house actually reeks of vinegar and rubbing alcohol now... ventilating when it's windy and thirty degrees isn't easy!)
our bathtub is gross, i know.  don't tell me - tell the landlords :)

I'm definitely saving this.  Maybe making it into a pillow for Raina's room??

I think I'm going to institute Sunday as Science Sunday in our house.  Do you have any favorite experiments to share?

And tomorrow...  Math Monday?


  1. These activities are too cool!!! Would like to invite you to share this with us at Sharing Saturday here..


    Thanks so much and have a great weekend,

  2. Thanks for linking up to Sharing Saturday. hope to see you again this week.
