Science with Erica Brannon
We are now fully immersed in our Chemistry unit! So far we’ve covered the basics of atomic structure and types of chemical bonds, providing us with the foundation to start the fun part of this unit next week: chemical reactions! As an extension of our chemical bonding activity, students learned how difficult it is to break the covalent bonds that hold water molecules together. We succeeded when we tried using electricity through the process of electrolysis – the bubbles in the attached picture means the water molecules were being broken down into Hydrogen and Oxygen gas! Students have been hard at work using various models of atoms at at each stage of our discovery process. Models of our scientific topics are extremely useful when the real thing is either too big or too small to actually use in class, and we’ll continue to use these throughout the year.
