Sorting of Earth Materials

We've looked at the layers of the Earth but there are more ways that nature layers things.  We've layers liquids by density.  Today we learned about how things sort by particle size.  Here's an example:

RAFT

Role:  The identity you take on as the writer (ex: Santa Claus)
Audience:  Who you are writing to (ex: Buddy the Elf)
Format:  What form your writing will take (ex: a Letter)
Topic:  What you are writing about (ex: How to find his Dad)

Today's RAFT needed to include the 4 layers of the Earth in its Topic.  The writing assignment needed to include the states of matter of the layers (solid, liquid, gas), temperature, pressure, density and if you like you can also include what each layer is made of.

Layers of the Earth

Important Points
-Names of layers
-How they layer
-Why they layer
-The state of matter of each layer

Everlasting Gobstopper?

Is a Gobstopper really "everlasting?"

We have started looking into DIFFUSION by watching the particles of a gobstopper diffuse in water.  We tested both cold and hot water.

Note for parents:  We answered the questions in class on 11/22.

The Amazing Magic of the Particle Accelerator!!

Particle Accelerator

Now don't be confused.  This may look like an ordinary microwave and well . . . it is.  But it does things you might have never realized it could.  This baby can make the particles of any substance move faster causing some items to change states of matter and even increase in volume.  Here is an example of what happened to a marshmallow - it's volume was increased like crazy.

I'M A GAS!!

I think my favorite part of today was when the principal saw me running around outside my portable, waving my hands above my head and shouting, "I'M A GAS!! I'M A GAS!!"

If you were absent you need to get the notes from a friend.

Take Home Lesson - Know the 3 phases of matter and the motion of their particles.

QUIZ!!!

Today was our quiz on density!  Don't freak out if you weren't prepared.  You can take this quiz over and over until you get 100%. :)

Safari from Hammari!

We were in Mr. Hammari's room today.  We got to use a lot of the lab equipment. Here is a little taster of what we did.  We didn't quite get 7 layers - 4 was all we had time for. :)

Density Field Trip!

Today we took the class on a field trip around the school.  We crammed everyone into small closets and found the wide open spaces throughout the school.  We analyzed the density of students in each location.  My favorite was the high density closets but I think they enjoyed the running around in the low density areas of the main hall.

Mystery Blocks

Yesterday the constant was density.

Today the constant is Volume!

I had a bunch of blocks, all the same size, that are all made from different materials.  They had to figure out which block was which based on the density (which they calculated).

Can you guess the constant for Tomorrow?

Wood Density

Mr. Ripplinger - you sly devil!  You took a 4x4 piece of lumber, chopped it up into different sizes, and had your students find the density of each one.
Some students thought the bigger pieces would have more density because of their size.  Other students thought the smaller ones would be more compact.
But very few could foresee them all having the SAME DENSITY!  MWAHAHAHA!!!
It's all made of the same material - all the matter will be spaced the same in the small pieces and the big pieces.

I'm your density!

Part One

Part Two

It is your density to learn about destiny. :)

Remember . . .

Making Rainbows

What a day this has been!  What a rare mood I am in!  I am seeing rainbows all over my room.

Proof that my students are learning how to measure the volume of liquids.  We felt like real scientists today using test tubes, beakers, GRADUATED CYLINDERS, and pipettes.  It was awesome!! 

Robots from the Cuboid planet

Every time I said the word "cuboid" I couldn't help but think of robots.  Don't know why.

We became pros at using rulers today - we measured LENGTH and WIDTH and HEIGHT.  Their powers combined (through multiplication of course), they are captain VOLUME!  Capt. Volume comes to the rescue of the poor oppressed robots of the planet Cuboid.  With his mighty ruler, he secures the poofiness of the robots' hair.  Captain Volume - he's our hero!

My Shampoo gives my lots of volume!

VOLUME! - how much space an object takes up.

How much volume does your hair have?

Key Questions -
What is Volume a measurement of?
What units do we use for Volume?
How do we measure Volume for:
   -liquids?
   -cuboids?
   -irregular objects?
