Turning Grapes into Raisins – Science for Kids
My daycare kids love grapes. They also love raisins. Now, we all know that a raisin is simply a dried up grape, but that probably seems a little puzzling to a toddler. After all, a raisin doesn’t look anything like a grape! To help the hooligans really understand, we conducted one of the easiest science activities ever. We turned grapes into raisins right here at home. The hooligans got to see for themselves, the transformation that takes place as a green, juicy, round grape shrivels up into a dark, dried, wrinkly raisin.
It a pretty cool process.
Even I was rather impressed.
And the best part was how simple it was! You just need a little time and patience. Ok… maybe a lot of time and patience.
Check it out!
Supplies for turning grapes into raisins:
Seriously! That’s it!
We stared with 5 juicy, ripe grapes.
They actually look like they were a little past their best, don’t they?
They might have been.
Oh well! They were perfect to start our experiment with!
Day 1
For weeks, the two-year old would head straight over to the grapes upon arrival to see if there had been any changes from the previous day.
DAY 10
Of course the changes were hard to detect day-to-day, but it was cool to see those grapes gradually dry up and get smaller and darker as the weeks passed.
Day 21
Flash-forward a couple of months… Sorry for the lack of photos in between days 21 and 64!
As much as the preschool hooligans were checking on our grapes regularly, I got a little lazy about pulling the camera out to document the scientific changes.
But hey, look at this!
Ladies and gentlemen, we have RAISINS!
Day 64
How cool is that?
And there you have it. Grapes to raisins in a mere 2 months, and we watched it happen!
For the record, we didn’t eat our raisins.
They’d been sitting out, uncovered for 2 months.
I can just imagine the amount of dust harboured in each little crease and wrinkle!
If you want to eat your raisins, you may want to use this process to turn your grapes into raisins. You won’t have to worry about your grapes collecting dust with this one!
