This week we ran two science experiments.

Experiment #1 Ramps

What objects can we cause to roll down a ramp?
We tried a hockey puck, laying flat.
Lochlan: It's not rolling. Put it on its side.
We turned it on its side, and it rolled down the ramp.
We tried a lego.
Ozzie: It's not rolling.
Carson: Because it is a rectangle.
We tried a domino.
It did not roll.
Carson: Because it's rectangle too.
But it did surprise us one time
We tried a cylinder, on its side.
It did roll.
Emily: It's like a circle.
Miles: It won't roll standing up because it's not round anymore, it's  flat.
We tried a block.
Ozzie: It's not rolling.
Lochlan: Because it is a square.
Morah Katie: Which objects rolled best?
Emily: The circles.
Morah Katie: What if we adjust the ramp?  What if we  make it steeper?
Let's try the domino now.  (It slid a little bit.)  What did we change that caused the domino to slide?
Matan: We moved the ramp to make it steep.
Morah Katie: The domino slid, let's try the block.   It did not slide.   What can we do?
Kids: Make it steeper.
We put a block under one side of the ramp.
We tried the block. It slid!
Morah Katie: We could make the block slide without adjusting the ramp, we could apply a force.
Force is a push or a pull.  Think for a second, what does gravity do to our bodies?
Ozzie: Push us down.
Morah Katie: We can use the ramp in reverse.  How will I get the block up the ramp?
Carson: You'll have to push it.
Morah Katie: Will I have to use a little or a lot of force?
Kids: A lot.
Morah Katie: How about the ping pong ball?
Kids: A little.
Morah Katie: What about getting the puck up the ramp? How much force will I need?
if it is flat? 
Lochlan: Maybe a not a lot, but not a little.
Morah Katie: If it is on its side?
Miles: Maybe a little.
Morah Katie: What are we applying to objects to get them to move?
Miles: Force.
We moved on to explore static electricity.
We saw what happened when positive protons and negative electrons attract each other.

Morah Katie: Please tell me what you learned about static electricity.
Jade: We rubbed the balloon on our heads and then put it over the butterfly. We FORCED the balloon on our head.
Morah Katie: We did use force to rub the balloon on our heads, and then how did the balloon use force?
Miles: The wings moved. I was surprised.  
Morah Katie: How did the balloon pull the wings up?
Jade: When we FORCED the balloon on our head.
Morah Katie: And what is force? 
Maya: It's when we make something move.
Morah Katie: By rubbing the balloon on our head, we took the negative electrons on our hair and introduced them too the positive protons of the paper. The opposite charges are attracted, they want to be friends, the balloon makes the wings lift.

Morah Katie: Have you ever swung on a swing?
Kids: Yes.
Morah Katie: We are going to make something in class today.
We took 2 chairs, string and metal nut.
Morah Katie: What did we make?
Jade: Something that kinda looks like a swing.
Morah Katie: A swing is a pendulum, a pendulum is made by hanging an object from something else. 
Lochlan: A swing can break gravity, because it's hanging down and it's not on the ground so it won't hurt anybody.
Morah Katie: It looks like swings break gravity, they hang down from the pole on top.  
Morah Katie: When you pull a pendulum to one side and let it go, what will happen?
Ozzie: It will fall down.
Matan: Gravity keeps everything down.
Miles: Gravity pulls things down so they don't float.

Pendulum painting
Morah Katie: What is going to make it move?
Kids: Gravity.
Morah Katie: What will happen to the paint?
Jade: It will drop down.
Morah Katie: What was surprising about the pendulum painting?
Colette: Watching the paint drop.
Rowen: It kept swinging.
Maya: The paint dropping, how it dropped, the pattern.
Lochlan: It's because of gravity. If you let go it swings back and forth.
Morah Katie: Would you like to demonstrate how gravity causes that to happen? 

We discovered that an object in motion will remain in motion until another force acts on it. 
We rolled a ball and it did not stop until it rolled into a the leg of a chair.
It stopped for one moment and then went another direction.
This led us to the idea of cause and effect.
Morah Katie: Does gravity affect everything?
Maya: Yes.
Morah Katie: Morah Jillian will be running an experiment involving cause and effect and gravity with dominoes.  Let's find out will happen when one domino gets knocked over. 
Morah Jillian: I lined up all these dominoes.  What do you think will happen when I knock one over? 
Lochlan: They will all fall over.
Lakshmi: I think so too.
Morah Jillian: Just like that one domino impacted every other domino. It is just like when we treat our friends with kindness. We become like the dominoes once we start being kind to others they start being kind. That it is the domino effect with kindness.

Gravity


Gravity
Morah Katie: Let's try an experiment. When we jump in the air will we float?
Lochlan: No because of gravity. 
Morah Katie: Please tell me more.
Lochlan: Gravity is really heavy and it keeps us down.
WE JUMPED,
 but did not float.
Morah Katie: If you toss a ball in the air will it stay in the air?
Matan: No.
Morah Katie: Why not?
Maya: Gravity.
Morah Katie: What is Gravity?
Maya: I can't remember but it's heavy and it's why we don't float.
Lochlan: It is strong and keeps us on the ground.
Morah Katie: Well let's see what happens when we drop these balls.

We expanded our ball drop experiment to a crumpled paper ball and plastic ball. 
Would they land at the same time?
We extended the experiment to compare the fall rate of a crumpled piece of paper to a flat sheet.
Morah Katie: Can we see gravity?  
Lochlan: No.
Maya: Yes.
Morah Katie: Where can you see it?
Maya: Everywhere. Outside. I'm not sure, but it's there.
Morah Katie: I think I know what you mean. We see it's effects.
Let's look at the jump/floating experiment again. This time look at your friends feet.
Did we see gravity?
Lochlan: Yes, because our feet fell down.
Morah Katie: Let's look at this, I am going to drop my marker. What do you see?
Evan: Your marker dropped.
Miles: Gravity. Gravity made it drop.
Morah Katie: What would life be life if we didn't have gravity?
Colette: We WOULD float.
Maya: Like being in space.
Lochlan: If you go to the moon you are floating.
Morah Katie: If we would be floating, what else would be floating? 
Carson: Trees and cars would be floating.
Miles: The whole school would be floating. 
Morah Katie: What would happen to the paint if it was floating?
Miles: It would be everywhere, but you could float to it and grab it.
Colette: Your bed would be floating!
Morah Katie: Would you be able to stay on your bed?
Kids: NO! 
Lochlan: Even your toys and tools would be floating!
Morah Katie: Who is grateful for gravity?
Kids: WE are!
Colette: Look Morah Katie! I'm floating! There's no gravity!
Over the next few weeks we will explore how gravity affects the things around us.

The children have enjoyed learning  about and celebrating Chanukah.
In the midst of the Chanukah season, they have continued to participate 
in a few key ideas we promote daily at The Gan.
The morahs created a short video to highlight a few of 
these foundational ideas.
We wish you a joyful winter break.

Chanukah is here!
Morah Tzivie is helping us learn how to light the menorah.
As we enjoy these fun nights with our families, we continue to put the story of the Maccabees in action in the classroom.
We had fun banding together to create a building block Beit HaMikdash (Holy Temple in Jerusalem).
Lochlan: We used all the blocks, it was hard work.
Chanukah fun was all around.
These young children discovered ways they are brave like the Maccabees every day in their own preschool way.
Lochlan: Not being scared of a cave with scary sounds, it can hit the walls and the echos can be loud.
Jade: Being nervous about singing on stage but singing anyway.
Colette: Going to my 1st swim class when I didn't want to because it looked scary but I did it anyway.
Lakshmi: Trying something new.
Miles: Not being scared in the dark by practicing being in the dark. 
Maya: Going to Great Wold Lodge when I wasn't sure if I wanted to go.
Carson: Not being scared of the dark. Turning on a flashlight can help you be brave.
Matan: Standing up for whats right.

We had great fun helping to fill the coin menorah! 
This blog will post on the third day of Chanukah, that means we get FIVE more days of fun!
Can't wait to see what days 6,7 and 8 bring!
Happy Chanukah!
