# Switch project

Last week, we learned about a new project that we were going to start which is a project where we are going to make three switches. The switches can be anyway you want it to be but after you make three, you’re going to use them for a game. The way that the game is going to work is that there is going to be two other people that each have half a deck of cards. Then, they will throw down a card each at the same time. If one of the cards is red, you will activate the switch closest to the card. If the cards are both red, you will press a middle switch. The goal of the game is to go as fast as you can. This project has to do with driverless cars.

# Atoms

Last week, I learned about atoms. Two days ago, I learned about the periodic table. I learned that in an element a periodic table has the element name, how many atoms there are and it’s atomic weight. For example, above is gold. In the top left, the number 79 is how many atoms gold has. The number of atoms determine the element. The words in the middle are golds name. Au is it’s name on the periodic table of elements. Finally the number on the bottom, 196.97 is the atomic weight.

# Electric flow

Two days ago, we learned about the flow of electricity. But today I got to light a lightbulb. The materials I used were a blade switch, a battery, a light bulb, and many wires. It total I used three wires. Two wires were attached to the battery. Then I attached one of the wire to one side of my light bulb. Then I took the other wire and attached it to the blade switch. Then I used one more wire to attach my light bulb to my blade switch. Then I just switched the blade, and then the light bulb lit up.

# Save the Elephants!

Ni Hao!!! Last Thursday, Alexandra Mor, a famous jeweler came to our technology class to teach us about a variety of her jewelry. Her main lesson was to teach us about how she saved the elephants. She discovered a kind of nut called a Tagua nut that when peeled, it looks like elephant ivory. This is important because many elephants (not in the U.S) were getting killed for their tusks. She showed us three different Tagua nuts. One was unpeeled, one was peeled and one was carved into an elephant. She also showed us some gems including ruby, emerald and amethyst. This experience made me more conscious about what I buy and how it’s made.
