Science Backlog, Part Two: Space Madness!!!
We raided the local library for image heavy books about the US space program. The book 'Exploring Space With an Astronaut' by Patricia J. Murphy was especially well received. The Frogs spent a lot of time poring over the photos of Astronauts working and living on the international space station. They asked a lot of questions about what they saw; " Why are they floating up?", "Why do they have seat belts?", Why are they wearing those helmets?", and the inevitable; "Can I have a helmet like that?"
Well, with a little creativity, some recycled milk jugs and soda bottles, and a bunch of silver spray paint, Yes you can!

Science Backlog: Part One
We chose to focus on applying the scientific method by setting up a variety of experiments exploring different concepts,- such as density, phases of matter, chemical reactions, and, physics- over the course of several weeks. Before we carried out each experiment, we asked a question, gathered a list of theories based on the children's observations- or in some cases imaginations- then put those theories to the test;
For one of our earlier experiments, we filled the sensory table with water and a variety of containers for pouring and filling. After the children had filled all of the containers to the brim with water we asked, "What do you think would happen if we put these on the front porch and left them there all night long?" Here are a few of the hypotheses that the Frogs offered up;
"They're going to melt!"
"They might get tipped over!"
"They are going to turn into ice!"
Keep in mind this happened in mid-February in New England...
Another experiment that invited a lot of lively speculation, was a variation on the classic "Will it sink or will it float?" game...
To prepare, we gathered a clear container, rubbing alcohol, water, corn syrup, vegetable oil and food coloring. We also collected a variety of small, relatively waterproof objects. We added food coloring to the water and rubbing alcohol to make it easier to tell the two apart. Then came the fun part!
We gathered all of the Frogs together for circle time, then asked "What do you think will happen if we pour all of these liquids into this container?" The general consensus was that the liquids would get all mixed up. We slowly poured each liquid into the container, and watched as each liquid quickly separated into it's own layer, making distinct stripes! We then asked each child to select an object from our collection. We went around the circle and asked "what do you think would happen if you dropped that into the container?" at first, almost everyone predicted that their object would either float on top...

...or sink to the bottom.

Until this happened;
Some objects started to sink, then stopped in the middle!
We asked the kids what they thought happened, and they were stumped! Then we tried to explain the concept of density, with mixed success. We think the majority of the Frogs preferred to think it was magic! Of course, if we can teach them that Science is kind of magic, maybe we can inspire them to keep asking what makes that magic happens.

From Solid, to Liquid, Back to Solid...
The idea for our "recycled crayon" project came from this book. The title not only serves as a metaphor, reminding adults to sit back and let the artistic process unfold with young children, it is single most important rule to follow in order to produce perfect rainbow crayon melts-trust us!
First, we put hundreds of extra crayons into our sensory table for the children to peel and sort.
Next, we put the peeled crayons into a heavy-duty zippered freezer bag, and let the Frogs crush them with rubber mallets.
Once the wax was cool and mostly solid, the Frogs were excited to examine how the crayon bits had changed up close and with all of their senses.
