Frog Species Back from Extinction!

A species thought to be extinct as a result of habitat distruction in the 1950's,  has just been discovered in a pond in Israel. According to USA Today in their article Frog thought to be extinct found in Israel pond  we learn that the Hula painted frog has actually survived in a small pond. Scientists are now scrambling to study them as well as trying to find ways to help these amphibians multiply and eventually be taken off the endanged species list.

5th Annual Save the Frogs Day!

April 27th will mark the 5th year in a row that Save the Frogs celebrate the efforts around the world to save frogs from extinction. With pollution and diminishing habitat for frogs around the world, frogs face extinction on every continent. You can help by organizing an event in your community. Visit Save the Frogs for more information.

In the meantime, you can begin your own unit study about frogs so that the children you work with know as much about frogs as possible before the great even. You will find dozens of fun frog themed activities, frog unit study activities, frog math and so much more in articles I have written describing the ways I have taught my own children when homeschooling as well as classroom activities I have used when teaching in the classroom.

Have fun with frog songs, frog games and read about a Hunt for Frog Eggs.

The Frog Pond in Winter

It's the middle of the winter and the frogs are all tucked in beneath a blanket of mud. The frog pond is frozen over and the children wonder if the frogs could be frozen as well. Some children believe that the ice goes all the way to the bottom. Some believe that ice forms at the bottom of the pond first. Others believe that ice forms on top first. We decide to do an experiment.

1. Fill a clear shallow dish with water and place it in the freezer.
2. Set a timer to check it ever 1/2 hour. Check to see if it is starting to freeze. If so where is it starting to freeze?
3. I made a paper with an outline drawing of the bowl and a place to record the time when checked.

We discovered that ice formed around the edge first. We then noted that the ice covered the top of the water before it finally froze on the bottom. Would that be true of the frog pond?

We then decided to go down to the frog pond to check the ice there.

NOTE: I went over the safety rules for going out onto ice covered ponds.

We used a crowbar to make a hole in the ice. We discovered that the ice was 12 inches thick but that the water was not frozen below that.

The Story of Bremer Pond is an article about caring for fish in a pond during the winter. The children loved listening to the article and had many questions as well as suggestions for scientific experiments.

Be sure to check out lots more frog related activities from our Frog Unit Study.

When we came back from the pond each day, the children would write letters or notes to their penpals about their discoveries. Writing about their discoveries gives the children a purpose for writing. Receiving responses to their letters creates motivation for more observation and discovery.
