The first time I made the discovery bottle. All The Dragons wanted to do with it was open it up to see what was inside instead of looking at the items through the bottle.
This time I set out different items and let the kids create their own discovery bottle.
One thing we were focusing on this week was the color blue, that is why there blue items. The cotton balls I added because I thought it would be fun for them to push inside the bottles. I would have never thought to add clothespins to a discovery bottle, I got this idea from my lesson plan at motherhoodonadime.
The discovery bottles were a mathematical science activity. Who knew putting stuff into a bottle could be called science and math!
We started with a question: How many items can you fit in the bottle?
How many clothespins?
How many cotton balls?
They started off counting the items they were putting in but soon lost count when they started adding handfuls of beads and marbles (of course).
But they continued filling and filling until the bottles were full.
When they were finished filling them up I asked them to dump them out so we could count how much stuff they shoved inside. They were very excited to dumb. As it goes dumping is a favorite for preschoolers.
Dump them out!
Pull out the cotton balls
Shake out the rest!
Then the counting started. The Dragons counted them first, then I helped them count them again to make sure we had the right number.
Doll Dragon had a 20 oz bottle and had 36 items.
Little Dragon had a 16 oz bottle and had 42 items.
This is where volume comes into play-mathematical science!
We asked The Dragons why the smaller bottle had more things inside it? We gave The Dragons some time to examine the items on each tray.
Doll Dragon saw that Little Dragon had more small items and less big items. She had more big items then small items.
Bigger items take up more space where smaller items take up less space. Thus Little Dragon had more items in his bottle.
