science for tinies: seeds in vinegar
Mar. 19th, 2013 01:03 pmBackdating this, posting for my records:
Project: Will Pea Seeds Sprout In Vinegar?
Materials: pea seeds, ziploc bags, paper towels, water, white vinegar
Explanatory details: My favorite experiment in 11 Experiments That Failed was the growing of the seedlings in stinky perfume, because it had a control group. I don't have any stinky perfume but we agreed that vinegar was a good substitute and set them up as per prior sprouting experiments.
How did it go: Great! Pea seeds do not sprout in vinegar (but they do in water).
Things we talked about: We each formed a hypothesis before we did the experiment - Junie thought the seeds would sprout in both water and vinegar, I thought they would sprout in water but not vinegar.
What Junie got out of it: She stated a hypothesis and tested it! So awesome! Also sprouting seeds is always exciting. (It really is - recently (late April, when I am typing this up - we have been planting our garden and testing the germination of the seeds we plant and Junie is asking good questions like "why do pea seeds look like peas but carrot seeds don't look like carrots".)
