Almost everyone uses chargers on a daily basis wether it to charge your phone or charge your computer. Most of us don’t really think “How do chargers work,” I know I don’t. Let’s learn all about chargers.

Chargers us e electromagnetic induction to charge batteries. A charging station send electromagnetic energy through inductive coupling to an electric device, which stores energy in the batteries. This is achieved without the need for metal contacts. Between the battery and the charger.

How does a Pulse battery charger work?

When batteries are stored in an uncharged state for an extended period, lead-suffer deposits from and harden on the lead plates inside the battery. Regenerators Send pulses of electric current through the battery, which in some cases may cause the sulfate to flake off the plates and eventually dissolve.

What did you learn about batterie? If you learned a lot and want to learn more feel free yo do some research on your own!

 

How do batteries work?

Batteries. They charge things what else. I can’t think of anything else, maybe I will just learn about them. I will tell you a few things about them as well! Let’s start learning!

A battery stores chemical energy and turns it into electrical energy.The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do some work.

How does a battery die?

When the active metal in the plates can no longer sustain a discharge current, a battery dies. That is the simple way to put it, but I thought that we were learning today! A car battery would “age” as the active positive plate material sheds due to normal expansion and contraction that occurs during the discharge and charge cycles.

Well that’s all for toDay on batteries did you learn a lot? If you did maybe you want to ask questions and learn more about batteries!

How do headphones work?

Wow headphones, they seem like such a simple thing. You plug them into your phone or iPad and you listen to music or whatever you need to listen to. Would you believe me if I said there is SO much more to headphones? Let me tell you all about how headphones work!

Well headphones pretty much work the same as speakers but they are the opposite of speakers, but wait headphones have speakers in them. Hmmm that’s weird, let’s move on we need to continue looking at how headphones work! Headphones turn electrical energy into sound by using special magnets to vibrate the air, it’s weird. The digital data is stored in the phone and that is what the headphones use. Kind of simple but a lot of science.

When you plug your headphones into an electrical source a current is pushed into the voice coil that creates an electric magnetic field!

That is all you need to know about headphones for right now. How much did you learn?

How do Microwaves work?

How do microwaves work? Well, I know they heat up food and kill germs but I don’t actually know how they work. Let’s learn all about them!

Food gets heated up in the microwave. Inside of the oven there is something called a magnetron. Inside the microwave  are reflected inside of the microwave made of metal material.
It absorbs the food and makes Microwaves cause water molecules which make the food heat up and then the vibrate.

A fun thing to think about is what will happen if I set the microwave to heat something up but I don’t actually heat anything up? Well the answer to that question is that the magnetron will create things that travel into where you cook your food and will be absorbed if there is no food or water just a running microwave those things floating around will not go into where your cooking your food and just go back to the magnetrons. To answer your question not much happens just a bunch of chemicals and stuff like that.

Well that it, that is how a microwave works!

We are done doing our rocketry. It has been a really fun experience. I learned a lot and I learned how to compromise and work in a group. I am super proud of my group and the rockets we built and how high they went. I think that set aside the few arguments we had we were a pretty good team.

Our first rocket we didn’t know exactly what we were doing and we had to rebuild it and we had to launch a second time. We had four fins and a narrow body and a nice nosecone. 

The things we used to keep our rocket together was electrical tape and hot glue. My favorite part of making the rocket was that we got to use the hot glue gun. For our first rocket we did pretty well and we had a lot of things to improve on.

For our second rocket we had no retakes and i was proud of that. Our teacher let us change one thing about our rocket. We decided on having three fins instead of four,we decided to do that because we thought the rocket would be lighter and go up higher. We also made the fins bigger and put the higher up on the rocket so that it woudn’t get stuck. The launcher was a really cool thing and it was home made which I think is pretty cool.

Our third rocket launch was the one where our parents were watching. Our rocket did pretty well I would say. We decided to name our rocket,its name was the Lemon and Lime rocket. We named our rocket this because of the colors which were yellow and green. We didn’t argue really,the only thing that we disagreed on was the jobs two people wanted the same job but they couldn’t have it but then it was resolved and it was all better. It was really fun to build the third rocket but i was sad that our unit was over.

I think that the rocketry unit was really fun and that I learned a lot. If I had a choice I would do it again. I also learned how to work my problems out in a group and the project was really fun. I give it a 10 out of 10.

 

Launching Rocket #2

We just launched our second rocket I am proud of it. I am kind of upset because it didnt go as high as we wanted it to go but I am hopeful that our third rocket will be amazing. I think that everyone in our class did pretty well. We made our fins bigger wich I cant tell if it helped or not.

Our rocket was blue and white. I think we may have focused a lot on looks then on the structure.Our group did fight but it was about small stuff so it was fine. My job was a pumper I pumped the the bike pump up to 50 PSI. It wasnt a very fun job in my opinion,but it wasnt terrible. I wanted to be Count Down Master but that job was taken by another person in my group. I hope that I will be able to be the Count Down Masteer for the next launch.

I am really excited for our next launch. For our launch we got second highest in our class, and I am really proud of my group

 

Design Rocket #2

When we started building our rocket it was going really well, I think that our final design turned out well I don’t know what we could have done to make it amazing. Now I will explain how the process works.

We were told that we could only change one thing about our rocket. The thing we would change about our rocket was our fins. We made the fins bigger and we put them higher, we also put three fins instead of 4. We used four fins on our other rocket. I think that 

I think that I have a few things I would change about our rocket. I would say that maybe we should have done a thick body because then more air would go into it, and it might have gone higher. Also maybe we should have kept the fins the same size and put four fins again. I feel that our rocket wasn’t our best work.

Overall I enjoyed the process of making it and if there were a third launch there are many ideas i have and I wish we could use them!

 

Launch 1

Our first launch we learned a lot. It was not very successful but we had a second chance and we fixed it and then it was the third highest int the class!

Our first rocket launch ever was not the best. Our nosecone fell off and one of our fins came loose. I think that maybe we should have spent less time arguing about the colors and more time about how stable it is and if we think there is something else we could add to it to make it even better.

Once we had the chance to fix it we used more for glue wich definitely helped. First we made a new nosecone, then I hot glued it on and then we taped it. That definitely helped. For the loose fins we hot glued the top and the bottom.

I think that next launch we have a lot of things we could do better. Maybe we could make the nosecone a little more skinny, and the fins bigger and more up the body.

I am really excited to see how our next launch goes and if we made enough improvements to get our rocket to be the one that went the highest.

 

Designing Rocket 1

                      In class we have been working as a team to create our first rocket design. The process has been difficult because you have to agree with everyone in your group, there are four people in my group. Our group name is Blast Off!!!

Our first design had four fins a narrow body and a nosecone. We used tape to keep the paper body together, and we also used tape to keep the nosecone onto the body. We hot glued the fins onto the body, our nosecone was made out of paper, our fins were made out of cardboard and the body was made with paper.

We used a narrow tube and covered it with paper, but we made sure that it could slip out of the paper that is how we shaped our body. With our fins we traced a triangle onto paper and then put it on top of the cardboard and cut four triangles. For our nosecone we used materials from the classroom the were circular, and we traced them and then cut them out. When we finished doing that we folded it in half and cut a line down the center and then rolled it and it made a nosecone.

I think that making the rocket was a super fun project. It used a lot of creativity and I can’t wait to make another one.

Animal and Country Study

Eagle Research project

In reading we  have been studying how to research. My research process was to find out different types of information about eagles and jot the information I found into a packet. On our book we organized our titles into subtopics. Our subtopics were, Hunting Techniques. Eagles Body Parts, Eagles Flight, Raising a Family and Nests and Eggs. WE organized our research books from easiest to hardest. And I think that really helped my group and I. I think that the most valuable thing I learned about the research project was hearing stories about what not to do such as not to copy other people’s work.

 

I applied my work from my animal studies to country studies by, organizing things into categories, and I think that really helped me during the process. And I also had help from an amazing partner.

We divided our chapters into categories we divided them into something called “ Cultural Universals.” The cultural universals are called, Politics, Social Aspects, Economy, Beliefs and Cultural Arts.

My title of my book is, “ The Cultural Universals of Poland.”

My favorite part of the project was working with a partner.bAnd creating all of the google slides.

What I found challenging was that there was some things that I couldn’t find pieces of information so that was very tricky. But I really liked the project.
