Salt water, Fresh water and Cooking Roosters

We are in a unit of earth science. Today we discussed the difference between fresh water and salt water. We looked at a huge world map and noticed that there is a LOT of water on the planet Earth! What we saw on this map (or on a globe) is mostly made up of oceans. Oceans are salt water. Lakes, ponds, rivers, streams and creeks are fresh water. (Even though we discovered most ponds are not very fresh because no water flows in or out of them!)

We watched a BrainPop Jr. on the differences between fresh water and salt water. We used our document camera to come up with a class list of these two different kinds of water. We all made a list in our Science Journal of fresh water/salt water sources.
Wow! We came up with some interesting facts about these two different types of water.
Look at this pie chart. The chart on the left shows the amount of salt water on the Earth. The chart on the right shows the amount of fresh water on the Earth. WOW! We had really better take care of our fresh water so we will have enough to go around. (Did you know there is a garbage heap the size of Texas in the middle of the ocean? We need to keep it clean, too.)
Our world is a magic place full of special shoes and socks. (This was taken on our walk to our favorite place to visit on Thursdays: the library!)
Ms. G had a wonderful lesson on "voice" in writing. The book she used was "Cook-a-doodle-doo!" by sisters Janet Stevens and Susan Stevens Crummel. ( NEWS ALERT: Susan Stevens Crummel will probably be our visiting author this spring! AND.....Janet Stevens went to our school when she was in second grade!)
We listened carefully and gave different "voice" to the way the words could have been written. Thank you, Ms. G for a wonderful library period. You are a great asset to our school and our district. What would we do without school librarians? We hope we will never have to find out.

Spelling test tomorrow. :)
