Rainbow Jar

Today we will be learning about density with this fun and easy experiment called the Rainbow Jar experiment. With a few simple ingredients that you probably have around your house, you can witness the magic of density.

Little Passports

How it works:

This experiment explores density, density is the mass of a unit of volume in a material substance.

Isabella explains it wonderfully at the beginning of her video which is on our channel and linked below.

Isabella used two cups and a bunch of pom poms. In one cup she had a lot of pom poms in the other just a few. This demonstration helps her to explain density.

Here is how we explain it. Almost everything is made up of molecules, the pom poms represent molecules. The more molecules your item has the denser it is (the less space there is between them).

We are working with liquids in this experiment, each liquid has a different density which explains why they stack up on top of each other. Each liquid creates its own layer based on its density.

Let’s get started conducting this experiment.

What you will need:

Tall Clear Container (Mason Jar)

Honey,

Light Corn Syrup,

Green Dish Soap or Blue Dish Soap,

Olive Oil,

Water,

Rubbing Alcohol,

Food Coloring,

Dropper,

What to do:

  1. First, gather your ingredients including a clean clear container, we used a mason jar.
  2. Next, let’s start making our rainbow! The first layer to put in is honey make sure to pour it into the center of the container.
  3. Then, mix some food coloring in with light corn syrup, we used purple food coloring.
  4. After that, put in the dish soap, our dish soap is green but if you use blue that is fine too.
  5. Next, add in the water, regular tap water we colored blue, again if you used blue soap then color your water green.
  6. Then, add in our olive oil, we put a pretty thick layer.
  7. Lastly, using a dropper add rubbing alcohol which we colored red (that is a great peak at how density works when you add the food coloring into the rubbing alcohol the food coloring sinks and sits at the bottom). We used a dropper and slid it into the jar on the sides to create a layer, if you shoot it in or if you pour it in you risk a chance of the alcohol picking up the color from the previous layers.

It's Women's History Month and I wanted to share s It's Women's History Month and I wanted to share some of our favorite titles this month to share with your children that celebrate Women's History. 

Girls Think of Everything: Stories of Ingenious Inventions by Women have been a favorite it our home. Have you read it?

If you haven't make sure to pick it up from your local library or bookstore. It is an amazing read and you will learn a lot about women who invented some things we take for granted every day.
I can't believe Isabella is learning pre-algebra i I can't believe Isabella is learning pre-algebra in 6th grade and actually understanding it and not miserable.

We are so grateful to @mrdmathlive.
Our February read aloud was "The People Could Fly" Our February read aloud was "The People Could Fly", by Virginia Hamilton and it has led us on some wonderful deep dives.

Hamilton retells a series of American Black folktales paired with incredible illustrations.

Having some fun in our homeschool creating a Yoshi Having some fun in our homeschool creating a Yoshi's Crafted World diorama. It was a lot of fun, we followed a printable from play.nintendo.com but then added our own flair with construction paper, colored yarn and whatever other craft supplies we had on hand. AJ loves it. 

What fun things have you created in your homeschool lately?
This week has been filled with snow. It's a new mo This week has been filled with snow. It's a new month and it came with a ton of snow. Been shoveling and schleping for days now. 

We took like 3 days off of book work from our homeschool this week because dealing with the snow and everything else I am responsible for is exhausting and sometimes self-care looks like slacking a bit. 

Dealing with the guilt of slacking a bit is another thing, trying to be in the moment and enjoy these moments with the kids is where it is at. Seeing the smile, and laugh while frolicking in this dreaded snow is where it's at. 

It's all about perspective, so find that perspective that makes you happiest.
We have been bombarded by snow, yesterday we spent We have been bombarded by snow, yesterday we spent most of the day playing and shoveling the snow. When we came in, I made hot chocolate and told a story from @storytyke.
