Experiment 2: Shiny Penny Results

LD found that the vinegar/salt combination was theshiniest. Interestingly, DD’s vinegar/salt soaked penny was NOTthe shiniest in her group (I think the water/saltcombination was). Because of this we talked about theneed for scientists to perform experiments over and over.

Experiment 3: Slurping Celery

What you need: 1) Take a stalk of celery, cut the stem and slice the celeryup the center. 2) Stand the celery up in two pots. Fill the cups withwater and add 2 drops of dye to each cup. (I let the kidschoose their own colors, but you get the best results withred and blue). 3) Observe every 15 minutes. 4) Since ED also participated we did a stalk from...

Experiment 3: The Celery Slurping Results

We got almost immediate results from ED’s celery whereshe took a big bite out of the stem! It made for interestingdiscussions as to why so much dye accumulated on thatside. When I asked LD why the water was going up the stalkwhen gravity pulls things down, he first answered, “Maybeit’s evaporating.” (Hmm… but it’s not hot in here I pointedout.) “Maybe it’s crawling. Wait but it’s not alive,” hequickly added....

Experiment 4: The Results

At first, the dye was suspended in the oil, but quickly the“fireworks” began. The red separated out first, followedby the blue and yellow (which looked green). We alllay on the floor and said “ooooh” a lot! This really wasa good experiment for the littlies.

Experiment 5: Science in the Kitchen

After many of our experiments, LD and DD want tocreate their own experiments. They add all kinds ofingredients to see what happens. In this “experiment”they added (as I recall): water, vinegar, baking soda, margarine, flour, yeast,peppermint, cinnamon, food coloring and pepper. They took it out to the garden to see what it woulddo to the ant trail. I heard that their “ant poison”worked (I was cooking dinner and didn’t observe).
