Before our Thanksgiving break, we brainstormed materials used in packing the gifts that so many of us ship and look forward to receiving from family and friends during the holidays. We discussed the packing peanuts (Styrofoam) as one type of packaging material. We conducted a simple experiment to test and see if Styrofoam is good for the environment. I for one have been guilty of throwing the packing materials out immediately upon taking the gift out of the box. We predicted what we thought would happen if we added H20 to the peanuts. We used regular Styrofoam peanuts and compared and contrasted them to starch peanuts. When immersed in water (H20), as my friends like to call it, the starch peanuts (Starch Tech), immediately began breaking down and dissolving. After, observing and attempting to break down the Styrofoam peanuts with H20 and other materials we had on hand, such as vinegar and alcohol, we concluded that the Styrofoam peanuts did not dissolve or disintegrate which means that they wouldn't be a "friend" to the environment. We came to the conclusion that we can help the environment if we use the starch peanuts, when we have a choice. I introduced the word "biodegradable" to my friends. I will continue to build upon this and we will continue discussing what products will biodegrade, when we return from break.
I have discovered that when I immerse my friends in science for an entire year, they develop a love of it, as well as becoming excellent problem solvers and critical thinkers; this in turn greatly enhances their reading and math abilities. Until next time, wishing you and your family a very Happy Thanksgiving!
A few weeks ago, my friends had a blast investigating dry ice and making ice cream using liquid nitrogen. When dry ice is placed in warm water, it immediately, starts to turn into carbon dioxide gas and water vapor, forming a really cool cloud, which is safe to touch and feel. My friends were fascinated observing how the cloud spilled over the edge of the bowl. We discussed how dry ice can be used as part of theater productions and performances to create a foggy effect. Through the process of investigation, I attempt to scaffold my friend's learning by asking questions,
providing hints and modeling, as needed. Research has shown that experiences with new types of activities or stimulation can generate growth in the brain within only a few hours after the experiences begin. By giving my students varied activities and many new experiences, I feel confident that they are making new "brain connections". I hope you can take time to celebrate all the new learning and growth that takes place this amazing year.
*Important Reminder: Dry ice will burn. Only an adult using protective gloves should handle dry ice. The clouds are harmless, however students should never directly touch dry ice.
