Link Link Summary: This week in class we were learning about elements of the periodic table. To learn more about this topic we are making a baby book about the element that we chose. The element that I picked was Molybdenum. I decided on this element because the symbol (Mo) is the first, and last letter of my whole name. We are making this baby book on google slides. The name Molybdenum means "lead" in Greek. This is because many people confused molybdenum with lead.  It is the 42nd element in the periodic table. This mean that there are 42 protons in the atoms that are in molybdenum. Each element has a different number. That is why it is a "special" number.  Molybdenum is used in aircraft and missile parts. Astronauts discovered molybdenum on the moon! Baby Book The first slide of my baby book was the birth certificate which included the name, nickname, discover date, atomic mass, atomic number, and some more. Here is the inform

http://sciencenotes.org/printable-periodic-table/ Summary: Have you ever heard of a periodic table and wondered what it is? Do you know what an element is? If you want to know more, than you are at the right place! Elements of the Periodic Table. Look at the elements in the periodic table above. In the top left corner there is a number, and the elements are in numerical order. That number is the atomic number.  Each e lement has a different atomic number.   The atomic number is the number of protons in the atomic nucleus. On the top right corner there is another number. This number is the melting point of an element. This number is usually in C °.   Some of the elements say "unknown" because scientists have not figured out yet what the melting point is. Example of a melting point: The melting point for titanium (Ti) is 1668 C °. Each row in the periodic table is called a period .   There are 7 periods in a periodic table. The fir st period only has

This is the last Experiment that we did in class BS=Baking Soda BP=Baking Powder CT=Corn Starch D=Detergent ?=The Unknown Summary: This week we have been working with different crystals, granules, and powders. We have also used some other materials that are not granules to do the experiment, like detergent! There was also a powder labeled unknown. We don't know what type of powder, or granule it was, so we have been doing different tests to figure it out. Some of the powders that we have include: Sugar Salt Epsom MSG Baking Soda Baking Powder Detergent Corn Starch We have been trying to figure out the unknown for a while. We have used some of our senses: Eyesight Hearing Touching Observing The way we used our eyesight to figure out what the unknown is observing. We put each sample of the powders on a paper, and wrote notes about them while observing. We looked at our observations to see if the Unknown had any of the same properties as any ot
