Tech 7 #2

We have started making paper airplanes in class and doing research about the 4 forces of flight to help our planes fly well. The 4 forces of flight are thrust, drag, lift and gravity. So far I have made 2 paper airplanes the first one was just from my head that I thought of myself and the second one was from a website my teacher provided for me.

Here is the first plane I made:

This plane might look very cool but it doesn’t fly well. It gets a good amount of lift but it doesn’t get enough thrust.

Here is the second plane I made:

This plane is very good. It gets the perfect amount of thrust but over time the lift kind of stops so the plane stops and hits the ground.

Next we are going to make planes out of wood and I’m going to try to make my wood plane a mix of the planes I’ve made so far. I’m going to try and make a long nose and have long aerodynamic wings.

Tech 7 #1

Today in Tech we are watching YouTube videos from the TV series How It’s Made. I chose to watch a video on how mirrors are made but I ran out of time to finish it. I still was able to learn that mirrors start out as flat thin pieces of metal that are very malleable.

Technology #9

After the circuit was put together I started to put the flashlight together. I had to drill holes into the pipe where the switch and where the lightbulb would pop out of the flashlight. After everything was put together and the flashlight worked I decorated it so I didn’t just look like a white piece of pipe shaped as an “L”. I colored the ends blue and then the tips of it red to make it red, white, and blue.

Technology #6

We had to make a switch that hooks up to a light bulb. For me making the switch was pretty easy it was just that I was cutting the cardboard that I was not cutting it right so it’s took me longer than needed. After I cut the cardboard correctly I put the switch together and tested it to see if it worked and it did.

Technology #5

I soldered my solder piece. I think that it came out well for my first time soldering. If I did this again I would try to not use as much solder. My solder piece looks like a bunch of lines connected to each other. It looks like that because I didn’t know what to design to do so I just drew lines. Overall I liked soldering.

Passion Project #4

After watching some videos about hydro dipping it helped me hydro dip better. When I did another phone case I was able to make a cool design and I was able to dip the case in the water in a short amount of time after spraying the paint. Overall I think that I did better on the second dip because I did research and got better at hydro dipping.

Here is my first try:

Here is my second try:

Which one do you like better?
