Bonjour, c’est un projet que nous avons fait en français où nous avons fait le masque du Roi Tut.
C’est une photo de mon masque. C’est le masque du roi Tut.

Middle ages
hello we have bin learning about the middle ages in science. We also did a project where we remade a ( card-bord ) castle.
About The Middle Ages
The Middle Ages
The Middle Ages was in europe from 400AD – 1400AD. It started wen the Roman Empire was destroyed. Many people think that every thing was wors in the Middle Ages so it can be called The Dark Ages ( every thing wasn’t wors ).
Feudal system
The feudal system is a form of class system. At the top of the class system is the king, then the nobles, then the vassals and finally the peasants are at the bottom. The king gives land to the nobles who give soldiers to the king, the vassals are the soldiers who give protection to the peasants and fight for nobles and the peasants work for the vassals.
Pulleys And Gears
Pulley
Pulleys are used pull string and something else well move in the opposite direction that you move the string. There are two tipes of Pulleys. Fixed Pulleys are attached to a structure mechanical advantage ( mechanical advantage is how much easier a simple machine makes something ) and move and gives able Pulleys are attached to a load ( load is what you’re pulling ) and give a mechanical of 2x.
Gears
Gears allow you to tern an object in a direction you otherwise wouldn’t be able to by having one gear tern another gear. There are 4 tipes of gears Spur gears can be used to tern something and it will move something else in another place, Bevel gears alow you to move a gear and it will tern another gear at am angle, a rack and pinion gear can change a turning motion into straight motion using a rack and pinion, the worm gears slow things down by using a gear and a spirle with teeth ( teeth are the bumps on a gear ) and a pole.
Castles
A castle is a structure which has a community in it. Castles have many parts a moat is a dich to makes it harder to get in during a war, a barbican is a tower used to protected the gate, the curtain wall and towers is an outer wall witch is the perimeter of the castle, the fortified gatehouse is the castle entrance but there are traps to trap intruders, the keep is the best, biggest and strongest tower and is the made area of the castle and he inner wall is a wall in inbetween he inner part of he castle and the curtain wall so intruders have to go through two walls.
Draw-Bridges
Draw-Bridges are the main entrenses of castles and alow people in the castle to deside whether or not they want people to come in and out. they do this by pulling the draw-bridge up and down. If the draw-bridge is up people can’t cross the mote if it’s down then they can. They do this byusing a pully and some castles also use gears.
Hypothesis
My hypothesis is: I will make a pully system for the drawbridge I will have a pully were one side is attached to the top of the drawbridge witch will be the load and you will pull down on something witch will pull the drawbridge up. I will make a bevel gear to move the flag up and down you will move a gear side wase and it will move the flag up and down.
Procedure
This is how I made my castle so far.
- Get a card-board box,
- cut that card-board box in to the shape of a castle,
- cut card-board into different rectangles,
- hot glue the rectangles into the keep and turrets.
That is what I have done so far.
sound
Sound
Hi we’ve been learning about sound in science.
What is sound?
Sound is vibrations when something vibrates it makes sound and then it vibrates the air which gets the sound to our ears.
What is echo?
Echo is when the sound bonus of a wall gets into your ear again.
Experiment
In are experiment we knocked on a bunch of surfaces like the wall a desk and the carpet the carpet made the sound quiet the wall no echo and the desk made a loud and echoey sound. this is a video of the project
this is a video about how the ear works
Fun Facts!
- Some walls are sound proof which means you can’t hear sound from the other side. They are normally used in things like fireworks.
- The volume of sound is measured in decibels this is used for things like devise volume.
Properties Of Sound
- Sound is a wave
- Sound is vibrations
- Sound moves at different speeds through different things.
Light
Hello, this is what are grade 4 science unit has been for 1 week (:
Natural VS Artificial Light
Natural light Artificial light
Natural light is light that is not man Artificial light is light is man-made. Examples of artificial light are:
made. Examples of natural light are: light bulbs, fireworks, glow sticks and
the sun, glow worms and fire-flies. ( some people disagree with this ) candles.
Emitting light vs. reflecting light
Emitting light Reflecting light
Things that emit light create their own light. Things that reflect light use light from things
Examples of things that emit light are the sun, that emits light and bouns it back in to your eyes.
TVs and candles. Egsapls of things that reflect light are desks, chairs,
Things that emit light are luminous carpets and posters.
Things that reflect light are non-luminous
Fun Fact!
Are eyes let in more light wen it’s dark and block of light wen it’s bright.
Light Travelling
This is the first experiment In the experiment we shined a flashlight at the end of a bunch of paper cards. my hypothesis was that the cards at the end would be more lit than the ones at the start because the light would be mostly blocked by the cards and my hypothesis was correct because that is what happened.
Here’s a photo (click this link)
What’s a good reflector?
In this experiment we had three items ( a smooth mirror, a crumpled piece of tin-foil, white paper and a lack of paper ) we shined a flash light on them and saw how the light hit the wall the mirror was the best. An interesting thing we found was that the light originally hit the white paper.
Habitats
Hello today I’m going to tell you about habitats (:
4 facts about habit
- Habitats must have food, water and shelter for the animals that live in them
- a lot of animals have to adapt to their habitat
- there are about 8 mane habitats habitats Polar, Tundra, Evergreen forests, Seasonal forests, Grasslands, Deserts, Tropical Rainforests and Oceans.
- habitats have a food chain which are: an animal is eaten by an animal which is eaten by an animal… an example of a food chain is coarl -> fish -> shark -> oarka.
This is a project I made ( press Jacob H )
WWW: It ended up working out how I could just add a link instead of embedding everything.
EBI: I did a better job with spelling.
Roz’s Recount
Roz’s recount
Hello I am Rozzum unit 7134 but you may call me Roz, this is when I was stuck on a large island, ( I didn’t know it was an island at the time ).
First I woke up and busted out of a crate! I didn’t know where I was at first. The first thing I saw ( other than the inside of the crate ) was a group of otters ( I thought they were people, I was wrong ) they ran away. I don’t know why though I’m just a robot!
Then I scanned/looked around the island. I saw weird soft pebbles and I decided it was sand.
After that I decided to clime up the rocks that were on the island to get to the forest which looked a lot safer than the beach. My grippy feet helped with the clime up the mountain. It was a bit hard to walk because of the rocks and trees. I was getting used to it when suddenly thunk! a pine cone fell on my head!

About Me
Hello I’m Mincat. I like video-games, I play a lot of Super Mario Odyssey, Super Mario Maker 2 and Minecraft. I like to have fun and you probably know why. I also like to eat candy. Skittles is my favorite candy. I am in grade 3 as of 2023. Fun fact about me: I’ve never moved houses in my life. I have an older sister. This is my first blog post.
