Water Cycle & The Atmosphere

The last two weeks of science have been spent learning about the water cycle and the atmosphere.

We have read several great books (and watched one movie)including:

Pandia Press’ REAL Earth Science has had some great, easy to do experiments that we’ve been able to complete.

Water Cycle

One day we spent over an hour just exploring the different forms of water (gas, liquid and air). Touching them, describing them and simply discussing them proved to be a lot more fun than I expected. IMG_5203

We also took the time to create situations where we could see water changing forms by simply manipulating the temperature:

  • Gas to Liquid (by cooling the air): By filling a glass with ice water (cooling the surface of the glass), we watched, over time, how the water in the air condensates on the side of the glass
  • Liquid to Solid (by cooling even more): we simply filled an ice tray with water and put in our freezer
  • Solid to Liquid (by warming): after taking the ice cube out of the freezer and set in a glass and watched how over time the solid changed to a liquid
  • Liquid to Gas (by warming even more): we put some water in a pan and heated it up until the water evaporated

Treyton really learned a lot with these simple experiments, I wasn’t sure if he would really remember it later on, but he seems as though he has. Science is probably his favorite subject, he is ALWAYS asking to do experiments!

Atmosphere: Air Takes Up Space

We talked about air and the fact that we can’t see it or necessarily feel it) but that doesn’t mean it isn’t there. We then did two experiments showing that air takes up space (has mass) and has weight. 

Experiment 1:

A simple experiment of looking and and experimenting with a balloon. We described what it felt like and looked like empty, and then described what it looked like and felt like full of air. IMG_5279

Experiment 2:

We took a glass of water and put it upside down in water with a piece of paper stuck on the bottom (inside) to show that even though we couldn’t see the air it was there, preventing the water from getting to the bottom of the glass.

IMG_5291Experiment 3:

We balanced three empty balloons on each side of a yard stick until it was level. We then added air to the balloons on one side of the yard stick and held the stick back up, this illustrated that air also weighs something (even if it isn’t a lot).

White Rabbit’s Color Book & Color Mixing

This week we read two great books on color mixing – our primary book was meant to be White Rabbit’s Color Book by Alan Baker but I also stumbled across Mouse Paint by Ellen Walsh that we also really enjoyed.

The kids had so much fun learning about color mixing, honestly if I would have known it was going to be such a hit I would have pulled out these books sooner!! All of them (yes, all three of them from ages 7-2) loved the books, particularly White Rabbit’s Color Book. They asked to read it multiple times a day and I caught all of them reading it on their own (in one way or another) throughout the last couple of weeks.

In order to really have a good time with color mixing, you of course have to mix the colors yourselves!!

For our first activity we did a hand print page – each kid got two of the primary colors, one on each hand and printed them on the page, then they rubbed the two colors together in their hands and placed one print in the middle showing the “new” color they made.

Sandwich Baggie Colors

Our second activity was a little less “hands-on” (giggle, giggle). We took sandwich baggies and each kid got to pick two primary colors to put inside of their bag. IMG_5219Treyton chose to make green, Alexa made purple and Audrey orange (again). They then mashed and smooshed their bags until the colors were mixed revealing the secondary color.  IMG_5221
