Insulators and Conductors

Posted on by

This week in science we made circuit testers. We made them by striping wires and tapping them together then adding “alligator clips”. It had to light a light bulb. I tested mine on many different things. 10/20 different items worked. From salt water to white gold. The objects that worked are called conductors and the objects that didn’t are called insulators.

8/10 of the items that worked had metal in them and thats why it worked. If it didn’t have metal thats why it didn’t work and that was an insulator. I think the salt water worked bc when the “alligator clips” touched the salt water it made contact or they had a reaction to each other.

Camping star party!!!!!!

So….. I just got back from camping. It was super cool!! When we got there we were so exited, we were running around like chickens with their heads cut off. hahahaha!!!!!  Any- way we set our tent up right away. (our = alex and I). By the way during all that craziness, ya know with the chickens stuff, I twisted my ankle.  After we got settled Mr.Major called every one to come over to him because we were gonna go on a hike. He told me to stay back be cause of my ankle. He also talked about TICKS. Fair warning, if you ever get the opportunity to go to Julian watch out for TICKS in the portal potties. Make sure to check in the corners for creepy bugs…..yep, there were big black hairy spiders, thick fat beetles, and stupid ticks. There was a choice of hot dogs or hamburgers for lunch. i had 1 hamburger and 1 hotdog. YUMMMMMM!!!!!!!!. When they went to hike Alex and I stayed to relax. I chrashed right away listening to my IPOD. Alex stayed because she had a headache. As you can see alex and I spent a lot of time together in fact we spent the whole time together. When they all got back Mr.Major and Mr.Doar started to cook dinner. Mr.Doar came with the idea of dough balls. They were de lish!!!! For dinner we had 2 different kinds of pasta and fruit. When it started to get dark we drank hot cocoa. When Alex and I were on our way to bed we loked up at the stars and the longer u looked at it the more stars u saw. Sooo pretty!!! Alex got very tired very quickly.  I was very kind and when to the tent with her. She had to use the restroom a lot so we went a lot. The portal potties were a night mare. We were so scared that it almost drove up to go in the bushes. It was like ticks were takin over. We finally fell asleep. We got up about 5 ish and got dressed around 7:45 ish. When we got up and walked to where they were cooking I felt sooo bad because i forgot i was so-post to make breakfast but Mr.Major forgave me. We got some hot chocolate and went back to the tent. We got up again and when to eat. We had pancakes and fruit and oat- meal. I had to add some cinnamon and brown sugar the the oat- meal because it had no flavor. Then again we went to the portal potties, soooo scary. We packed up our stuff and put it in Mr.Majors car. Mr.Major gave Alex and I the option of coming back to school or going on a hike and eating . We chose to go back to school. Mr. Bordan took us to Dudleys bakery and we got bread and chocolate chip cookies. We continued home. We finally got to school and here I am know writing this for u!!! thats all thanx for listening.

science robot (sumo bot)

This is the robot that belongs to the group exploding penguins, Cady, Calista, Morgan, and I.

I built the chassis* and they programed it. There is 3 sensors. 2 touch sensors and 1 ultrasonic sensor. If the touch sensor is pushed then it will back up or move forward. The ultrasonic sends out a signal like a bat, When it hits something it comes back to it and thats how it knows when to attack its enemy. Our offensive* strategy was  to have 2 lego pieces that would flip the opponent over.  Our deffencive* strategy was a big green wall the blocked people from fliping us over. The

The object of this project was to make blades for a wind turbine. They weren’t           exactly efficient, but they worked.

My groups first attempt didn’t work out so well. They were big rectangles with                    a slight pitch. It got a volt of 0 -.60.

Our second attempt worked WAY better. They were big long triangles. We pitched the blades to the right. You can see them below. They got a got voltage of  1.05


our best design

Our last attempt dint work at all. They were obtuse triangles. Big and fat. We pitched them very, veryslightly. It got a voltage of 0. Here is a picture of the last attempt blades.
