Make A Map-Buoyancy

Make A Map-Buoyancy

On December 1st, we made a buoyancy mind map. I learned a lot about what buoyancy and fluid means.

Fluid means liquid like water, gases, air and helium. Fluids don’t resist the way solids do, because if you push liquid it doesn’t push back at you. If you push solids, it pushes back at you.

Buoyancy is why things float in the water. For example if you drop your goggles in the pool, then it will float down slowly because of buoyancy. If you try to push down something with air in it like a beach ball, when you push it down as low as you can and you let go it will fly out because it has buoyancy force. Also if you put something in the pool it moves aside to make room. It is called displacement. When water moves aside, you wouldn’t be able to see it.

Make A Map – Gravity

Make A Map – Gravity

On November 15th, I made a mind map of gravity. I used BrainPOP to make the mind map and to get more knowledge about gravity.

I found out that everything in the universe has gravity: Apples, Earth, the Sun, the Moon, even people.

I also found out that gravity will keep the moon orbiting. If the moon didn’t orbit, there would be one country that is always night. And the rest of the countries will be day. Gravity also keeps the stars and planets orbiting.

The Moon’s gravity pulls toward the Earth. Then it creates a tide. 

Unfortunately, I did not find a lot of information about gravity, but I am happy I found some :).

Make A Map

Make A Map

On November 22th, I made a map about forces. I used BrainPOP to find out the information about force. I found out what net force, velocity, vector, friction, acceleration, non-contact force and contact force mean.

Some examples of contact forces are pulling, pushing, dragging and friction. Contact means like you are talking with someone, touching something or interacting. For contact forces, it means touching something. So if you add contact forces together, it means you are touching something to move.

Non contact force is the opposite of contact forces. Non-contact means that you aren’t touching anything to move. A example of non-contact forces are magnetism and electrical forces cause they are doing things by themselves. Like if you put 1 magnet close together with another one, it will automatically connect.

Friction is when something is about to slow down, speed up or turn any direction. 3 examples of friction is dragging, contact force and acceleration.

I learned a lot from the BrainPOP video, and enjoyed making the mind-map about forces.

Ancient Greek Food

Ancient Greek Food

For my 2nd seminar, I chose Ancient Greek Food. Here is what Joyce and Beni (Presenters) shared with us.

Form

Greek food is really healthy, they eat lots of wheat and bread, they eat lentils, grapes and vegetables. When Greek people eat dinner, the fruit is on the side and the vegetables are the main food. The one thing Greek people don’t eat is red meat. Like chicken or animal meat.

Causation

This happened cause there’s too much consumption of wine and too much salt in other food. And it protects you from Alzheimer and other diseases.

Change 

Greek food is better because Chinese Food has too much oil. It affected the world by protecting people against Alzheimer and diseases.

I enjoyed this seminar cause it’s food. 🙂

Seminars – Mark Zuckerberg

 During the seminars, I went to the Mark Zuckerberg seminar with Ms. Laura. She told us that he was actually the co – founder of Facebook. His friend was the owner, but eventually Mark Zuckerberg took over.

Form

 Mark accidentally created Facebook. He did when he was in university. He was messing around with codes. Then, Facebook was created in 2004. 

Causation 

  If Facebook wasn’t created, you wouldn’t be able to donate for charities, you wouldn’t be able to share thoughts, or even recipes or shortcuts for things,you can also bring people together, share political ideas like how to vote wisely, and people very far away can communicate. This is why Facebook is good.

Change

  It affected the world by helping people in need, and selling things in a easier way. Like you wanna sell a table for $2000, so you ship the table or you take it all the way to the person’s house and the guy who wants it pays you.

Why I liked it

  I really enjoyed this seminar because I don’t use Facebook and I want to find out about it. I thought he was the founder not co-founder of Facebook.
