Welcome to Room 1's blog. We are a Year 4-8 class at Te Mahia School situated on the Mahia peninsula. This year looks to be bigger and brighter than ever. Our teachers are Miss Kereru each day until 12pm. Then Miss O'B from 12pm until home time. We are a dedicated bunch of learners who take risks daily and are not afraid of hard work. Check out our class blog to see how Room 1 roll.
a raw egg (you may want to do a few in
case your egg breaks)
a hard boiled egg (so we could compare it to the raw egg)
white vinegar (poured 200ml vinegar in each jar)
2 glass jars or plastic containers with lid (we used glass jars)
Place your raw egg in a jar and cover it
with vinegar do the same in a separate jar with the hard-boiled egg. You will notice the reaction of the egg shell with calcium
carbonate and vinegar. It will bubble for the first day (below)
second day you need to change the vinegar. After 48 hours we carefully rinsed
the raw egg and noticed it was transparent! Cool! Isn't it
amazing? Basically it is an egg without a shell! I will let your curious minds figure out how the egg shells disappeared..
Bet you the tamariki can't wait to get their hands on the raw egg to see if it bounces!!
Watch this space for some of the tamariki's hypothesis and conclusions...
