I was inspired by Lisa at 5 Orange Potatoes to try this fizzy experiment with the girls today.
Materials:
cooking oil
water
glass jar or clear plastic bottle
food coloring
effervescent antacid tablets (aka Alka-Seltzer)
Caution: Adult supervision needed with young children as this experiment uses OTC medicine
Method:
Step 1: First you fill your jar or bottle about 1/2 [...]

[note: this is an experiment we did last year]
Today’s experiment was making a homemade pH indicator using red cabbage.
I saw this cabbage chemistry experiment at DIYScience and just had to try it at home. Caution: This experiment requires the use of a knife, poisonous chemicals and hot water. An adult should assist with [...]

(Last year’s experiment re-printed here).
So we did work on the density experiment last night. I must say the girls are really excited about doing experiments. We first placed some objects to see what would sink or float and in which layer they would end up. We had the girls [...]

We took common household objects to see if they would sink or float
Materials:
Various items found around the house
The items we chose were:
polished stone
a cork (or rather 3 corks glued together by my eldest daughter for another project)
a sea shell
a really large button
a pumice stone
popped popcorn
marshmallows
other items include: keys, coins, [...]

I got this fun idea from About.com
They always seem to have the neatest ideas on all kinds of subjects.
Our supplies
5 clear glasses (those wine glasses you don’t use anymore now that you have kids are a great idea)
granulated sugar
food coloring – blue, green, red, yellow
water
tablespoon – measuring spoon and flatware
straw
patience – lots
Step 1
Place 1 [...]

Just had to share this model of DNA we made and brought back from the Indianapolis Children’s Museum last week.
You make them by stringing ziti pasta and wagon wheels on 2 white pipe cleaners for the sugar-phosphate backbone, and then joining two sugar phosphate strands with intertwined orange and red pipe cleaners, and intertwined blue [...]

We did this coloring changing milk experiment a little while ago, and it was easy to do with materials from your own cupboards.
Materials
Shallow plate
Milk (the higher the fat content the better, buttermilk would work too)
food coloring (we used red, blue, yellow and green)
liquid soap (Dawn works well)
We poured milk onto the plate then added our [...]

I found a relatively child-safe way to explore magnetism. I saw on a kindergarten website a great idea to safely house magnetic and non magnetic items.
Safety note: I would supervise children under four with anything magnetic or small objects.
Quarter sized coin tubes are great for this purpose! For around [...]
