geology with cookies

Hi in my science class I had to excavate chocolate chip out of chocolate chip cookies

What is a geologist?

A geologist is a person how studies the earth and rocks and minerals

check out this video about geology 

Minerals are melted  into rock forms and are sorted into these categories: metamorphic, igneous and sedimentary

Some cool rocks are just a lot of minerals squashed together or melted together with all of the heat and pressure.

 

Innovation Day: castles in the middle ages

Hello and Welcome to my blog for Innovation Day on Medieval castles and Pulley systems.

Background research:

In the middle ages the lord and the king and all of their family lived in castles. Moats normally surrounded  the castles and the castle most of the time inclosed a little town or a little village. They also had drawbridges so that enemies could not get in.

Castles

  • Many kings lords and nobles lived in the castles
  • There was no bathroom in the castles just a little room that stuck out of the castle wall

Drawbridges

  • A drawbridge is a bridge that moves up and down people in the middle ages
  • They were used for safety and to keep bad people out of the castle

Lords and Serfs

Here is a picture from my research booklet of the differences between the lords and the serfs:

This is the feudal system. The Lords were at the top and were most powerful and the Serfs were at the bottom least powerful.

 

Here is a link to my blog on Pulleys.

Hypothesis

My hypothesis is that a string if i pull it will pull the drawbridge up and put the string on a pulley to move it down. I thought I would use two sticks and put the pulleys on the sticks and connect the string on the pulleys to pull it up and down. My research suggested I could use string and pull on the string to make it a moving drawbridge.

 

Procedure

First, I glued three walls on a base of cardboard  with hot glue

Next, I glue two pieces of cardboard and poked holes in it .

Then, I put string in the holes and attached it too the drawbridge and I added the pulley

Finally, I painted and added turrets and decorate.

Here is a picture of me during the build:

Here is a picture of me during the Scientist in the school workshop when we learnt about Gears and Pulleys:

Final Tour of my castle:

 

Self reflecting conclusion

I did not follow my original plan because it did not work so I went with a different plan see how I it changed above in the procedure.

If I made a castle again, I would make sure that it has different ways to move the drawbridge.

I would have changed nothing about my castle and I am proud of the finished  product!

 

 

Building with Rock

Hi, my name is Star and I am going to tell you about building with rocks .

The stone age people used stone to make axes and other tools . People also carved and painted rock. We do not paint events and stories on rock today,we do create stone sculpture’s and other statues for the public and places to mark important events and people in our history.

How did people build with rock?

Thousands of years ago stone age people made their most important buildings from rock

In the past people most often built with stone that where common in their area

Ancient Greece

Thousands of years ago the greeks built large  buildings using limestones and marble. They carried the rock using ramps wagons and logs that rolled on the ground like a conveyor belt.

Medieval Europe

In Medieval times used stone too build important statues like castles and churches.

While people in the past used mostly stone to build with now we use mostly bricks concrete and wood

stars pulley

Hi my name is Star and I am going to tell you about my pulley system

What is a pulley?

A pulley is a type of simple machine it can help you lift something that is really heavy it has something called a groove it is made from a wheel and axle

 

Different types of pulleys

There are many different types of just to name a few there are a fixed pulley and a movable pulley

in this video it is a fixed pulley i am showing you a fixed pulley

sound experiment

hello everyone! I am going to tell you about sound experiments

experiment 1:  we take a cup put plastic wrap put the wrap over the cup and put the string around the cup with the wrap pour the salt on the top of the wrap and then take a tuning fork hit it on a solid and then put it near the salt.

experiment 2

take a cup and fill with water and get a tuning fork hit against solid and put in water

Watch my video to see what happened…

personal recount

hi i am star this is my personal recount we are learning how to wright a recount here is my personal recount

First let me tell you about my first cruise ship in Italy. I got on the cruise ship with my family. It was huge! When we first walked in , there was a grand hallway that led us to the rooms and different areas on the cruise ship.

 

We walked to our room, we stayed in room 13 and got settled in.  The room has a window and no balcony. I was happy there was no balcony because I thought when the boat moved we would have gone flying off the balcony! We always woke up early, we were always first to get breakfast. There were cereal boxes and pancakes. It was a buffet bar but they served us. My favourite was cereal and juice. The view of the ocean was really cool.

 

Each day, me and my sisters went to the kids club. I won a medal! My group was older so we played tag and games and didn’t  get medals but  my sister’s group was younger and they did a parade and she got a medal. 

 

Next, we kind of enjoyed the pool but it was super salty! Even if I closed my mouth I could still taste the salt. I had to drink orange juice each time I came out of the pool. The view at the poolside was really really good. 

 

Finally, we stopped in many different places for a few days. The one stop that stuck in my head was one restaurant in Italy. I got spaghetti with butter and it was really good.

 

we also used our recount skills to create our  recount from the wild robot

 

star’s science experiment

Hi, I am star this is my first science experiment in grade four. We Explored how light travels and how it reflects.

my question:

how does light reflect?

Hypothesis

I think it is going too reflect off of the mirror

Procedure:

1 I gathered straw-clay flashlights and cards.

2 I put x on cards. put on clay on the bottom line up cards shine light off of the mirror

conclusion

Light did reflect off of the mirror because the mirror is a great reflective material.

Puppies

Puppies

I love puppies. They are energetic, playful and fun. They bark a lot and they roll around and like to play fetch. Puppies are so much fun. They like to have walks and play with their owner or rest with their owner. They like to chew on dog toys. Puppies like sniffing around, barking at a visitor, jumping around, and just being dogs. Do you have a dog?

If you do you need to get some information about your dog because they are more wilder than you think.

 

They are really cute animals.

Some dogs are really wild and some dogs are really sleepy.

 Fun facts about dogs

  • Some dogs are so fast they could beat a cheetah
  • Dogs do not sweat like we do
  • Your dog can be right pawed or left pawed
  • Dogs are really good swimmers
  • Your dog is amazing at being a dog
  • Dogs are really cool they can help you if you need it
  • They will keep you safe no matter what
