All right.
So remember, we talked about reversible and irreversible.
Yeah. And how we said that like pancake batter, once you mix it
all up and cook it, can the pancake go back to the batter? No.
So we're talking a little bit
more about that today with firewood logs.
So do you know why?
Have you ever had a campfire?
The lesson that I taught today was a phenomena
lesson on tree sap and why trees
why logs crackle in fire.
So let's just watch and listen.
Make sure I have this turned up.
I would have loved to have
been able to actually have a little campfire
so they could see that in real life.
And, you know, watch it as it grows into the fire
and then hear the woods crackling.
Besides seeing it on a video, I think it's always awesome
if you can put it in real life for them.
That's it? What was happening?
Maya. It was getting burned and there was sap in the tree.
So the sap started bubbling
because the fire was inside of it. Ok.
When I was looking through
trying to find a lesson to teach,
I try to relate it
to the standards that we have for second grade science,
like the reversible and irreversible.
So when I'm looking through the phenomena, I'm
going to make sure that whatever lesson I pick
is going to be related
to a standard because that's what we're assessing.
Do you have any questions about this?
What do you wonder?
when we ask kids what they wonder
after we teaching a lesson they've actually gotten
really well at coming up with really interesting questions.
Some of them, like,
I don't even know answers to myself, but yes,
they're really good at coming up with
I wonders. What do you wonder about Jackson?
How
is the sap like getting out?
Oooo - how is the sap getting out?
What do you wonder?
How did the sap get in?
Emma?
How come when the sap
heats up, it like gets really bubbly and kind of looks like foam.
it does look like foam, doesn't it?
All this down here looks like foam. Yeah.
Like the sap,
it looked like rootbeer
like soda,
foam... a lot of other types of drinks.
We learned about like
like how forms can not get back like into their normal forms.
So like if you had cake batter and then
you cooked a pancake with it, then you couldn't
put the pancake back to cake batter.
I liked it. It was fun.
There's always one person that tricks the teacher.
So inside the trees, we have the wood,
we have the bark, we have, there's air pockets,
and then there's all the water and the sap.
And then when we cut the tree and start heating it up,
that water heats up and it kind of starts to bubble
and comes on out. Kinda cool, huh?
Next time you have a campfire watch and see
if there's true sap that comes out.
I really enjoyed the site.
I liked it because it did have quite a few of the
lessons and videos that we can relate
and pull in to our science as we're teaching.
And it kind of gives them that one more piece of real world.
I can stand up there and talk about it, but
until I have something, a visual to show them,
that's what really helps.
