Week5_Prompt#3

The periodic table is made up of elements. These elements are classified as metals, non-metals, and metalloids. The non- metals can be found on the right side of the periodic table. Metals are found on the left side of the periodic table and the metalloids are found right in between them. The only other non-metal that you may find on the left side of the periodic table is hydrgen (http://www.accessscience.com/images/periodic_table.gif) a link to show the placement of the metals, non-metals, and metalloids.

Week4-Race-Car

The Design Squad faced some problems in their race car problem. They were assigned a tricycle and a wagon. They had to form a race car out of the two things.During the challenge they benefited from each other alot. They helped each other and kept each other in mind when they were creating the parts. They had advantages in using the materials that came with the items given. Like the bolts and screws.
I would approach the problem by awaring my teamates of that problems.Then I would look up any thing that can help me to solve or solve my problem.From watching this episode I learned that having a constant variable can be a good and bad thing. They can either benefit you or make u fall in completing your task. Sll because you cant get ride of them and you must use them.

Week3_Prompt#2

Noble gases in group 18 don't form chemical bonds because their outter shells are filled, there for they are stable. These noble gases have very little tendency to loose or gain electrons. Like when two elements that are on the periodic table form to create a element that is not on the periodic table. For example, when C and O share electrons then creates CO2. Carbon only has four electrons on its outter shell, which makes it un stable. Oxygen has six electrons on its outter shell, which makes it stable and has less of a tendency to loss or gain electrons.
