Water & Air Week

This week's theme was water and air, and we had fun with it.  We did all kinds of scientific things.  First of all, we learned that scientists call water H2O.  Next, we learned that water can be found in 3 forms...a solid (ice), a liquid (we called that drippy water.), and a gas (clouds).  Then we did all sorts of experiments to find out what sinks and floats in water, that air is lighter than water (that's why bubbles always go up), water has surface tension, water magnifies things, that water level goes up when you put things into it, water evaporates, and water condenses.

Below are pictures of some of our experiments.  Because scientists always make a hypothesis before their experiments (and we are scientists!), we made a lot of hypotheses.  Some are included below.  We celebrated if we were correct and if we weren't, we learned to say, "I learned something today!"

We started an evaporation experiment in our classroom.

Here are our predictions.  The one on the left is for the jar with the lid.  The predictions on the right are for the jar with no lid.

Here's a picture of condensation.  We boiled water in a tea kettle and caught the steam in a jar.  As it cooled, it turned from a gas to a liquid.

 

 

We made ice in the 3 different containers and predicted which one would melt first.

Here are some of the words that we used to describe the ice.

Who knew that watching ice melt could be fun?

We experimented with different items to see whether they would sink or float in water.  Can you guess which items sunk and which ones floated?

 

 

 

When we were doing sink and float, we found that a ball of clay will sink...

 but if we formed it into a boat it would float!

 

We put drops of water on different coins. First, we predicted how many drops would fit on a penny.  Here are our predictions.

Jeremiah-1
Martin-28
Jenna-4
Eoin-100
Hayden-3
Jacob-40
Christina-5
Isabelle-3
Madison-8
Mrs. Rife-5
Evan-2
Brady-15
Natasha-2
Lucy-6
Alex-40
Sky-22
Shane-1000
Mrs. Moneymaker-27
Mrs. Brockaus-34
  The penny actually held 28 drops of water!!  (Who's done this before??)

   

Do you see the bubble of water on the penny?   Scientists call this surface tension...we just called it water with 'skin' holding it together!

We poured yellow oil into blue water.  Some of us predicted that it would turn green because blue and yellow make green (like the water on the right).

We discovered that water magnifies things when you look through it.

Did you know that corn starch and water mixed together make a fun goo.  It's not a solid or a liquid!?  It's fun to play in though!

We poured liquid into different shaped containers.  We found that the liquid changes shape to fit the container.

To prove that gas takes up space, we poured red liquid into a funnel.  The liquid wouldn't drip into the bottle because the air couldn't get out.

When we stirred the water, we saw bubbles come out.  The gas was escaping so the liquid could drip into the bottle.

We've all heard it before, "Don't blow bubbles in your milk.  You're going to make a mess!"  Well in kindergarten, it's okay to make a little mess once in awhile.   We mixed paint, soap, and water with a whole bunch of air for this painting project!  We will be using our bubble paintings for a background for a future art project.

Air is a gas, and it takes up space.  It's also fun for painting!!
