The Blue Planet

Today we began our new science unit by exploring how much water is on Earth. First, students made their predictions about how much water is on Earth. Next, we used a beach ball globe to represent the Earth.
We tossed the globe 100 times and kept a tally of how many times our right pointer finger landed on water or on land. From this information, we were able to determine a percentage of water compared to land. We did this three times to make sure our information was accurate.

Our experiment concluded that about 72 percent of the Earth is covered with water. Our experiment proved to be almost exactly what scientists say is the amount of water on Earth.

Thank you Ms. Russell, you're wonderful. I love getting a little peek at what the children are learning and how creative your lessons are and more importantly, what a lasting impression it has made. Elias loved it! What a great way to learn!

That does sound like fun. What an engaging way for the kids to learn hands-on about math and science concepts.
