Anyways, we are learning about acids and bases with the good ol' red cabbage indicator. This experiment was a big hit.
 |
| We started with our liquids and identified which ones were sour and which ones were not by tasting all of them (and Oh My Goodness - I had no idea that alka seltzer was sooooo bitter and disgusting).... |
 |
| ...and added red cabbage juice... |
 |
| ...and observed the changes! |
 |
| They both identified the acids, the bases and the neutrals. |
We also observed chemical changes at the end of the formal experiment, when acids and bases were mixed together, and to the delight of my children, there was an EXPLOSION of bubbles.
We went through two entire boxes of baking soda, about a litre of lemon juice, and probably 2 litres of vinegar. It took a long time for them to tire of this one, even though we've done this a zillion times! Something about the added color made it so much more cool!
On another note, we went to HLSA's (Home-based Learning Society of Alberta) "Not Back To School Picnic" at a park. I don't know why, but I was fully expecting to be welcomed with warmth and to meet several other moms and their 8 and 6 year old boys. That didn't happen, but I did meet another mom, who was equally as overwhelmed as I, and we hit it off pretty well. And wouldn't you know it - she is an ex-pastor's wife (not an ex-wife...but her husband is an ex-pastor, just like mine) and their story and experience is identical to ours. IDENTICAL. I should start a support group, because this is, like, the 4th or 5th family we've randomly met with the same experience. And yet, I'm the only one who seems to be bitter. Just like that alka seltzer. Bleah.
