Public speaking reflection

Hi guys! Today I am going to tell you about my public speaking.

First I am going to tell you what my speech is about. My speech was about why crab trapping should be stopped. In my speech, my three main points were animals that have been affected by crab traps, the number of declining crabs, and Winter the dolphin’s story. I also added a paragraph about what traps are.

The part about public speaking I found most challenging was speaking. I found speaking very hard because for me it is very scary to speak in front of people. I also found it scary because everybody was looking at me. When I found out I got into the finals, I was very happy but I also got more scared because I would have to talk in front of grades not just one class with eleven people. When I arrived at the gym, I found out I was going first. I was so nervous and my heart was beating as fast as the wings of a bee. When I got called up to stand in front of the gym, I started to shake a lot because I was so nervous. Then again, everybody was looking at me and that just made me even more nervous. In a few seconds, I started, and even though I was so nervous and scared I did my speech in front of the crowd. Then I was done the scariest part, it was over.

The part I found the easiest was writing my speech. I found writing my speech the easiest because I enjoy writing. I also found writing my speech the easiest part because I was writing something I like, not a boring topic. Although it was a little bit hard to think of my third point. Overall, I think writing was the easiest part of my public speaking because I enjoyed it, and it did not involve doing something in front of a crowd.

Next time for public speaking I would speak a little bit louder, try not to get as nervous, look up at the audience more, and have more hand gestures.

 

Speech:Why crab trapping should be stopped

Records show a significant decline in the number of male adult blue crabs in Chesapeake Bay. 79 million was slashed to 39 million in under a year. Crabs were the victim… traps were the problem!(Puase for 2)

Hi grade 4 students, my name is Raisa and today I am going to tell you why crab trapping should be stopped. I am going to tell you about animals that have been affected by crab traps, the number of declining crabs, and Winter the dolphin’s story.(Puase for 3)

 

Before I tell you about the trapping of marine animals, I should tell you about traps and what they are. Traps are a way of catching food. Traps are put in water and they are left there until a fish or crab goes inside, or a fisherman moves the trap. Traps are used so fishermen don’t have to wait for a fish or crab to come while they can be doing other things. In the 1920’s, Benjamin F. Lewis invented the crab pot. A crab pot is a way that you can catch crabs. You are probably wondering what the difference between a crab trap and a crab pot is?(Puase for 1)The difference is that when a crab goes in a crab trap, the crab can go out any time the crab wants to go out, but when a crab gets caught in a crab pot, it is very hard for the crab to get out of the trap.

 

Did you know that a large percent of crabs and other marine animals have been declining steadily for years?(Puase for 2)

In China, there were 600,000 to 700,000 pairs, mom and dad, in the 1990s.  By 2010, about 20 years later, there were only 300,000. In the world, the crab population has declined from about 405 million to 282 million. 

 

Have you ever thought of how many marine animals have been affected by crab traps?(Puase for 2)

When people use crab traps they lure other marine animals into the traps and when the marine animals go into the traps they can get very injured. Fishing traps break and injure coral, making it go lighter. Did you know that coral is a real animal?(Pause for 1) Also, turtles have been getting caught in crab traps.

 

Well… here we are, we have arrived at the main point of my speech. Have you heard the story of Winter the dolphin?(Pause for 3)

I must say this is not a kind or pleasant story but the hard truth and reality of what it takes to get that fish on your plate! (Pause for 1)

On a cold winter morning, a baby dolphin got tangled up in a crab trap. When the baby dolphin tried to free herself, the ropes that were securing the buoy got tangled around her tail and mouth. A nearby fisherman saw her gasping for breath and went to set her free. After she was set free, the baby dolphin did not swim away from the boat for about 30 minutes. The fisherman knew that the baby dolphin was too tired and injured to swim so he called Clearwater Marine Aquarium. The rescue team arrived a few hours later and caught the baby dolphin. Even though the baby dolphin was very hurt, she was not easy to catch. When the baby dolphin arrived at the aquarium, the team of marine biologists named the baby dolphin Winter because it was a cold day. The marine biologists helped Winter. Sadly, her tail was too damaged to save so they had to cut it off. Since they had to cut Winter’s tail off, Winter could not go back in the wild because it would be to hard for her to swim without a tail. Kevin Carroll made Winter a prosthetic tail that she could swim with. People with prosthetic limbs got to meet Winter, it was very special! 

 

We must stop crab trapping to save the crabs!  We want crabs to survive and live a good life.  We must stop trapping to save innocent animals such as Winter from being harmed or killed in these traps!  To help  stop trapping, tell other people what you learnd about these traps so they can help speak up again when they see them!

 

Cookie science project

Hi guys! Today I going to tell you about my science project about geologists.

What are geologists?

Geologists study the history of the world. Geologists are poeple who look for rocks, minerals, and try and predict when things are going to happen. For example geologists try and predict when a volcano is going to erupt.

Earth Scientists more relevant than ever to oil and gas industry | CSEG RECORDER

What we did in the task?

In the task I tried to excavate the chocolate chips out of a cookie. First I wrote down my prediction of how many chocolate chips I would find in the bottom of my cookie and the top of my cookie. After I was done excavating my cookie I ate the cookie and it was very good.

Rocks and minerals

Rocks are made of many different types of minerals.

Please see my blog about rocks.

 

Innovation Day: Medieval drawbridge and castle

Hi guys! Today I am going to tell you how I made my medieval drawbridge and castle, and some backround  information on the medieval times.

Castles

Castle are places that people built for protection from enemies in the middle ages. The first castles were made out of wood. There were usually only three rooms in a castle. Sometimes there are moats around castles. A moat is water that surounds a castle. Sometimes castles can suround a little village. People still build buildings that look like castles because they think they look nice.

Drawbridges

A drawbridge is a type of bridge that usually leads to a castle. A drawbridge is a way that you can protect yourself from enemies by lifting the bridge up. A drawbridge usually goes over a moat. A drawbridge can lift to let boats go through. In the medieval times, drawbridges were usually made out of wood.Bridge, Waters, Drawbridge, Flow, Travel, England

(London bridge)

Lords vs Serfs

Lords lived privileged and serfs did not. Lords lived in nice and big houses, but serfs lived in wood and mud houses with straw beds. Lords had nice clothes and serfs didn’t. Serfs had to do farming and take care of animals, while the lords would get the stuff they made and harvested. The boys usually got to learn to read and even write. If the girls lived in a very privileged family, they might have learned to read or embroid. In the medieval times, the lords were one of the people who had the most power. Some serfs would be called freemen. The serfs had the least power.

(feudal system)

Knights

Knights usually fought on horses for their master. Knights also sometimes fought on foot. To be a knight, you need to be able to afford armour. The best soldiers were knights. You need a lot of money to become a knight, so if you became a knight your family would have probably had a lot of money. You could make a lot of money by being a knight. You can get a lot of money by winning a battle or war. Sometimes if you do a very good job as a reward you can be given a special name.

How I got my information

First I looked in some books with medieval drawbridges leading to castles. Then I looked online and found some facts about medieval drawbridges. Next I wrote down my facts on a piece of paper. Finally, I drew a picture of what my medieval drawbridge and castle would look like.

Hypothesis

I planned to use cardboard for my castle and the bridge of my drawbridge, then I planned to use my pulley from the “science in the school bag” to make my drawbridge go up.

Procedure

1.I got some cardboard and started to cut out shapes that I needed to make my drawbridge.

2.I glued some pieces of cardboard together to make a castle to attach my drawbridge to.

3.I made a door for my castle with straws and attached a string so it could hang on to the top of the castle.

4.I cut a little piece of a bamboo stick about one inch long, and wrapped it in green and grey pipecleaners.

5.I put a hole in the first end of the drawbridge, and glued the bamboo stick in the hole with some hot glue.

6.I made a hole in the piece of cardbaord and stuck a bamboo stick about four inches long in the hole, and put a red straw over the stick.

7.I attached the piece of cardboard to the first end of the drawbridge with a pipecleaner, and then I did the same thing with the other side.

8.I glued the other side of the drawbridge to the castle. Next I glued the pulley to the bamboo stick that was 4 inches long, and attached the string to the bamboo stick that was one inch long.

9.I wrapped the string to the pulley.

10.I painted my medieval drawbridge and castle.

11.I added two little pieces of cardboard about two inches long inside the castle to be tables, and then I added to smaller pieces of cardboard about the same length to be benches.

12.I made four little pipecleaner plates to put on the tables, and then I added four little pieces of different colour pipecleaner to be the food on the plates.

13.I made a spiral staircase by getting one bamboo stick and piting pieces of cardboard on the stick.

14. I cut a small piece of cardboard and glued it to the top of my castle were the spiral staircase would lead.

15. I made a bed by cutting a tiny piece of cardboard and putting pink pipecleaners for the pillow blue pipecleaners for the sheets

16. I made a little night table beside the bed.

17. I added another little piece of cardboard right beside the spiral staircase and made another bed with many different colours for the pillow and sheets.

(Video of me pulling the string of my pulley)

Results

My drawbridge worked when I pulled the string that was in the groove of the pulley.

(My final tour of my castle with harry potter characters)
Conclusion

Next time I would start out with one box so I don’t have to cut multiple pieces for my castle walls and floor because, it is extra work and it would have been easier to start out with one box.

Pirates

In my opinion, I don’t agree that being a pirate is a good thing. I don’t agree because pirates live on boats where there can be storms with big waves. I don’t like warm places but pirates do. I also don’t agree because I don’t like sword fighting. Finally, I don’t agree because I don’t like funny pirate songs.

I don’t like going on boats, because when there are big waves you can’t make them stop. I don’t like places that are warm because they are too hot for me. I don’t like sword fighting because you can get poked with a sword and that hurts. I don’t like funny pirate songs because they don’t sound that good. That is why I don’t want to be a pirate.

 

 

 

Rock Stars

Hello my name is Raisa and I am going to be telling you about rock stars. There are a lot of cool types of rocks and they are all rock stars.

The rock basalt belongs to the Igneous family. Basalt started as a hot liquid rock called magma. When magma cools it hardens into igneous rock. Basalt cooled more quikly above ground. Where the rock cools afects  how it’s shaped and Volcanic Rock, Background, Template it made of.

The rock shale, belongs to the Sedimentary rock family. The rock shale started out as lots of different rocks, shells, and tiny skeletons. The rocks, shells, and tiny skeletons got washed to the bottoms of lakes and oceans. More and more layers of the rocks, shells, and tiny bones built upp on the others that created a rock. The bits and pieces  have been pressed into rock after a few million years. The rock shale is smooth because the water washes over it, and over time the water becomes smooth.Cheltenham, Arid, Badlands, Barren

The rock marble is from the Metamorphic family of rock. The rock marble comes from rocks that already exists, like the Sedimentary family. The rock marble started out as members of the Igneous family and the Sedimentary family. Some of the marble rocks were made after intence pressure over a long time. the rock marble comes from limestone. Limestone is a soft member of the Sedimentary family of rock.

Pulleys

Hi guys! Today I am going to be telling you about pulleys. A pulley helps lift somthing that is very heavy.

There are 4 different types of pulleys. The types of pulleys are a fixed pulley, movable pulley, compound pulley, and a block & tackle pulley. A pulley is made out of a axel and a wheel. The more strings you have atachted to the object the easier it is to lift the object.

A fixed pulley is a pulley were you pull the rope down to lift the object up. A fixed pulley is made out of a axel.

A movable pulley is a pulley that is movable. In a movable pulley you lift the string up to pull the object up.

A compound pulley is a pulley with two wheels and two axels. One axel and whell is at the top of the pulley and the other axel and whell is at the bottom of the pulley. To lift up the object  you pull the rope down.

A block and tackle pulley is a pulley that has two wheels and axels. the wheel and axels are both on top of eachother in the block and tackle pullley. In the block and tackle pulley you pull the string down to lift the object up.

Today I made a fixed pulley. I made a groove out of tinfoil. I used three cups as the base and attachted them with red electric tape. i used pink string as the rope to pull the sharpener up.

Sound experiments

Hi guys! Today I am going to tell you about my science expariments. I leared that sound travels slow in gas faster in liquid and even faster in solids like wood.

Expariment 1

Hypothesis

I think that vibrations cause sounds when things move.

Conclusion

When I hit my tuning fork on my desk and then put then put it over my cup with saran wrap and salt, the salt vibrates. I also heard a loud bang.

Expariment 2

Hypothesis

I thouight that when I hit the tuning fork on the desk and then in the water it would do nothing.

Conclusion

My hypothesis was wrong. When I hit the tuning fork on my desk and then put it in the water the water buzzed. When the water buzzed some of the water flew everywhere.

 

Science Experiments

Hi my name is Raisa, I’m going tell you about my first science exparement in grade 4.

Question

How deos light travel?

Hypothesis

I think that the light will travel fast. I think the light will travel in anyway.

Materials

The materials that I need to use are clay, paper, pencil, ruler, and flashlight.

Procedure

1.First I gathered all of my materials.

2.I drew an x on three of the cards and made hole with my pencil on those same cards.

3.I drew a bulsie on the card that I did not use yet.

4.Then I lined  the cards up with bulie as the last card.

5.I stuck the cards down on my desk with red clay.

6.Finally I shined a flashlight through the cards and it hit the card at the back with the bulsie.

Conclusion

My hypothosis was not right. It was not right because light can only travel stright.

A little newsletter

Hello everybody, it’s me Raisa back today. It’s Friday, November 12th, 2021. Today the temperature is 13 degrees. Today in Winnipeg there is a lot of snow, but in Ottawa there is none. I personally wish that there is snow here in Ottawa, but the weather is just weather and I can’t do anything about it.
