First Juice, now Jello!

What's the best way to end the week? Making a treat to eat and learning at the same time, of course!
On Friday afternoon, we made Jello for Science. Monday, we reflected on our learning from our time in the kitchen.

I asked the kids: Why did we make Jello?
Evan explained that it would be a good way to show different states of matter when he said:
Its solid, and then liquid and then solid.

I then had the students think about and walk through our Jello making process:

We poured the sugar into the bowl, and it was a solid. (Adam)
Observing the solid crystals.
 We added hot water and we mixed it. The solid crystals dissolved. (Haylee)

Mixing to help the solid crystals dissolve in the liquid,
Next we put cold water and mixed it more, and then put it in the fridge (Sean)

And now... we wait!

Some further thoughts a few students had about the different states of matter that the Jello moved through,..

When we put it in the fridge, it made a solid, and when we ate it, it turned into a liquid in our mouth. (Katelyn)

When the Jello mixed with our saliva, it turned to a liquid (Sean)

Once the Jello was ready, everyone enjoyed a serving, and then we discussed how we could tell that the finished product was a solid. We did this by checking for the three properties of a solid.

It has mass/weight (Gabby)
It takes up space (Evan)
It keeps its shape (Chantal)

When I turned the bowl upside down, the Jello held its shape and didn't come out (Charles/Ciera)

Last but not least, the students shared some thoughts about eating the Jello!

Enjoying the finished product,
It tasted really good (Adam)

It was really delicious and I wanted another bowl (Gabby)

It tasted awesome (Katelyn)
