Ahhhhh...there is nothing like the sound of popcorn exploding around a saucepan over a hot gas cooker to do some thinking and learning about measurement. Today we were investigating the volume of corn kernels before and after popping, and the capacity of different size spoons to measure the kernels.
Our investigation using popcorn in maths today turned up some interesting conclusions. We got to measure corn kernels using three different kinds of spoons and fill up a container that was near enough to half a cup. We found that the teaspoon took 30 spoonfuls to fill half a cup, the dessert spoon took 11 spoonfuls and the large serving spoon took only 2 and 3/4 spoonfuls to fill half a cup.
We found that you could get more kernels onto a larger spoon and we learned that the CAPACITY of the larger spoon was greater than the teaspoon.
We also predicted how much half a cup of popcorn kernels would actually make and we chose what we thought was the most suitable container to put the popped corn into. Here is us guessing which container it might fit into.
We found that half a cup of popcorn actually makes quite a lot!
Then...of course we had to eat it!We learned today what volume and capacity means - tomorrow we are going on a hunt around our classroom to find things that have volume and capacity.
mmmm YUM! Well done rm 21! =)

What amazing learning room 21
ReplyDeletewow you guys are for heaps of adventure this term.can't wait to see what's next and i cant wait to be part of it.lynette
ReplyDeleteWow Room 21! Mrs McPhail really knows how to make learning fun using hands-on practical activities to learn about measuring and capacity/volume. I wish I could be a member of Room 21! Work isn't nearly as much FUN! Keep up the great work and most importantly have FUN with your learning experiences!
ReplyDeleteThat looks alot of fun! Popcorn is very yummy and good for you and also saves money if only a cup makes a big bowl thats a lot of people fed! Keep up the good work Rm 21 Alex Rowe
ReplyDeletei like the way that everyone patisapated in making popcorn from bailey. :) :(
ReplyDeleteIt is good to budding scientists in room 21 practising their measuring skills.
