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. We call this the water cycle.
|
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". |

What will happen to the water in the jar with the
lid?
Some of our hypotheses…
The liquid will stay the same.
It will evaporate through
cracks by the lid.
The water will evaporate onto
the lid.
What will happen to the water in the jar with no lid?
Some of our hypotheses…
All the water will evaporate.
A little water will evaporate.
The water will stay the same.
It will make a puddle in our room after it evaporates.

You can see the line on the left jar
that marked our water level on Monday. As you can see, it has
dropped a little. We are going to keep our experiment going
for a couple of weeks to see if the results change. |
 |
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 experimented with different items
to see whether they would sink or float in water. |

Can you guess which group sunk and
which group floated? |
|
We put drops of water on different
coins. First, we predicted how many drops would fit on a penny. Here
are our predictions. Tyler...10
Yates...7
Haley...1
Tymber...2
Bryan...1
Kylee...2
Dalton...1
Melinda...9
Nolan...2
Abi...2
Angel...3
Jacob...5
Zach...1
Alyssa...3
Mikayla...1
Kara...1
Owen...2
Aden...2
Cameron...1
Zachary...6
Nicholas...1
The penny actually held 33
drops of water!! |

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