We finished building our houses, and they are amazing! Feel free to review the following vocabulary with your child:
· Design – A plan of the shapes, sizes, colors and building materials needed to create something
· Model – A small copy of a structure
· Structure – A building or something built of parts arranged in a special way
· Support – To hold up or keep something from falling
What happens when you add Borax to boiling hot water?
Through this experiment, students learned to make a hypothesis: a tentative, testable answer to a scientific question or an "an educated guess." A hypothesis also has to be testable since the next step is to do an experiment to determine whether or not the hypothesis is right. A hypothesis leads to one or more predictions that can be tested by experimenting.
Students created shimmering crystals using a simple chemical process. We supersaturated hot water with borax, lowered a pipe cleaner shape into the liquid, and left it suspended overnight. As the water cooled, the borax formed into crystals upon the pipe cleaner.
Students learned that crystals are solids that are formed by a regular, repeating pattern of molecules connected together. Most crystals come in geometric shapes with sharp, straight edges and smooth sides.
Room 9 & 11 will be sharing their learning every Friday.
