In our new unit in science we are studying about atoms, elements and the periodic table. So far we have learned that everything is made up of atoms. Today we read about how everything is arranged in a certian pattern and scienctist can study patterns of crystals by using an x-ray diffraction machine. The x-ray beam passes through the crystal and creates a pattern on the film. Scientist can use that pattern to then create a modle of the crystal. We where able to create a modle of a salt crystal using red and green gum drops and by taking our individual salt modles and conntecting them togerher we created an even larger salt modle all in the same shape making sure to follow the pattern making sure that the same colors where not touching.
