Scientists in the School!

Hey guys, today I’m going to tell you all about the Scientists in the School thing we did. The Scientists in the School was a scientist that we saw on a zoom call. He mailed us a bag filled with stuff. One of the things he gave us was a plastic container filled with a mystery powder. He said that the experiment that we were going to do today is figuring what’s in the mystery powder. He said that we should have a plastic container of Epsom salt, baking soda, vitamin C, corn starch,etc. First, we filled three plastic containers with warm water. Then, we tried to see how many tea spoons of each chemical we would need to put in until it wouldn’t dissolve. Then, we put some of each of the liquids on a paper and we waited until it dissolved. Until then we put some vitamin C and other things together and added cabbage powder and we saw it bubble, and that’s how we knew what was in it. It was cornstarch and baking soda.

Bottle cap pen

                                   Bottle cap pen

 Sometimes I have trouble making my drawings thicker. Have YOU ever noticed how hard it is to make your drawings thicker? Our new project allows you to choose the size of your pen. allow me to introduce the T pen. It makes drawing better and more fun. There already is a pen like this, but it’s super expensive, this one is pretty cheap. 

 

                                It will make drawing easier

 It can grow and shrink which makes it super handy for drawing because you can switch the font without having to switch pens. The T pen is really handy for writing! The pen itself isn’t very big, so it’s good, like a normal pen but with better features. 

 

                                                 Reusable  

 If you think this idea is bad for all sorts of reasons, then maybe you’re right, and if you are right, then good for you, but at least it’s reusable. all the parts of the pen are reusable. 

The pen is reusable because it’s basically a sponge with color in it. So just take off the sponge and squeeze the color out of it and use it as a sponge.

 A lot of it is made from plastic, so you can just remelt it down and make something else. The bottle itself can be used for other projects so it’s also reusable here’s a link to bottle caps in case you want to make your own. Bottle cap fun time, 

 

                                   Everyone can use It

The fact that our pen can grow makes it easy for almost everyone to use. For example, blind people can feel how big the size of the marker is, disable people without hands can use their feet, Etc. If you’re mute, deaf, Etc, then you can use the pen just fine, if you can’t use it, that’s fine too, you can have a friend draw with and or for you.

 

                                           Summary

So in the end, the pen is really easy to use, it’s reusable, it makes drawing easier, and everyone can use it, so in the end, it’s really helpful. So, I think you should buy it, just saying, even though that’s my opinion. But if you do, use its power for good

cookie excavation project.🍪🍪🍪🍪

Hello everyone, today I am going to tell you about my cookie excavation project and how it went. First of all you need to know what geologists are before I can tell you about my project. Geologists have a cool and strange job, they find rocks and research them and sometimes if there lucky the rocks can have some kind of weird information about the past. If your wondering what I mean by information, I mean that if a rock was created by a volcano it would have signs on it that you can research. Here is some more info about geologists.

 

What Ms. M told us to do is to take a cookie and a toothpick, skewer, and mini stick to excavate(excavate means to break, crack something and see the inside) the cookie. Ms. M also wanted us to write how many chocolate chips we thought there were, and then excavate the cookie to see if we were right. Here’s a picture of me excavating my cookie. Here is a short video of someone explaining what geologists are, in case you want more info

innovation day project

Hello OJCS students. Today  I am going to tell you about my innovation day project. Our teacher told us to build a medieval castle with a working drawbridge with gears and pulleys. Starting my castle was okay but some parts were a bit harder. Like making the drawbridge, Cutting out the archer holes, and making the actual castle.

Background information about the middle ages

So my medieval castle is a stone castle with a working drawbridge that uses pulleys and gears to move up and down. My castle is mostly made out of cardboard and some other materials. But real castles back then were made from wood and stone and iron and metal. Castles back then also had a lot of traps and and holes for archers. They also had holes on the roof of the entrance so they could pour hot tar or lava (not real lava, I’m talking about very hot materials like melted iron). I choose a stone castle because they are one of the coolest castles in my opinion, The stone castles were also heavily fortified.

In this paragraph I will tell you about some more interesting facts I found during my reading, For instance, To be a Knight you would need to pay for all your things like your Horse and and armor and pole. But if you were a foot soldier you wouldn’t of needed to pay for your axe, bow, arrows, and spear. Another interesting fact is that  if you wanted to be a knight you would need to start training at the age of around 10/11. You would need to leave your family and go to a relative or friend who is willing to teach you. Here is some info about the knights in the middle ages .

Drawbridges

Drawbridges are like normal drawbridges but they can go up and down. The point of a drawbridge is for the King/Lord/Queen/Lady to have a quick escape and even if the enemy starts to follow him/her the drawbridge will go up which will therefore block them letting the King/Lord/Queen/Lady escape. The way a drawbridge would work is by some people spinning something that is lifting the drawbridge. It was pretty hard for the people to lift up the drawbridge but the King didn’t care as long as he lived. Here is a little link to how drawbridges work

 

Hypothesis

For my hypothesis I wanted to make my own pulley. I would then put a string on to the pullet and attach the other side onto the drawbridge which would then pull the drawbridge up or down.

Procedure

Miss M told us to build a working drawbridge so the way I imagined it is a piece of cardboard attached to the drawbridge that can go up and down. So I took some gears and attached it to the walls  on both sides and then took a very long stick/skewer/pole that goes through the gears witch will then be stuck to the gear. Then i will add a crank so I can crank instead of slowly and painfully spinning the gear. Then on the stick/skewer/pole i put two strings and those strings attached two the drawbridge therefore I made a working drawbridge.

here is a link to some info for a stone castle. 

My self reflecting conclusion

My castle sort of turned out how I want it. The drawbridge turned out good but not in the way I wanted it. Next time I would change ho the pulley and gear system works and I would also make my castle smaller because my castle is pretty big. In the end I am happy with my castle but it’s not perfect.

here’s a picture of my castle for now. now It’s black and has a pulley and gear system in the middle.

Here is some more information about pulleys if your are interested 

Here is a video of me explaining how my drawbridge works and how my castle turned out.

being a pirate is cool

I would love to be a pirate and always sail to different islands. Finding Gold sounds so fun and it would be cool to have a bunch of gold things. If being a pirate means I get to have a  sword and my own cannon then that sounds fun. If I am a pirate I can dress up like a scary person and go around saying” ahoy maties, how’s the sailing goin’. It’s a pretty nice day right”, that would be awesome and funny. It could be cool to have a big and fancy boat, with a big boat you can go so quick and fast and I like FAST. 

 

It could be cool to follow treasure maps and just normal maps for treasure like Diamonds and Emeralds and Rubies and Amethyst and Tanzanite and Painite. (fun fact, Painite is the rarest gemstone in the whole world). It would be cool to look at Dolphins and Whales and maybe even Sharks while you are steering the boat. My conclusion is that it would be really cool to be a pirate.

Desert Life

HI, Blue Energy here, today i will tell you about desert life.

what is a desert?

A desert is a place that normally gets very little rain or snow. This means that that deserts are very dry. there are hot deserts and cold deserts. hot deserts are very hot through out the day and are very cold during the night.

Animals of the hot desert.

In the day time animals hide from the hot sun. Snakes, scorpions, and lizards hide under rocks or bury themselves in the sand. Some animals can go under the ground to keep them cool. Animals that eat plants get water from seeds and plants.

plants of the hot desert.

cactuses (or cacti) keep water in their stems. They have sharp spines, like needles, that helps the cactus keep away animals. Ome desert plants wait a super long time (years) for rain to make them bloom.

Animals and plants of the cold desert.

Animals and plants have ways to protect themselves from cold and dry wind. They can live with very little water.photo of desert sand

Pulleys

Hi, Blue Energy here, today I will tell you about the pulley I made and the other kinds of pulleys there are.

What is a pulley?

a pulley is a wheel and axle with a string going over the wheel and that string has a hook and that hook gets attached to something you want to lift up. A pulley doesn’t make it easier to lift something but the more strings there are the easier it gets.

different kinds of pulleys.

there are more than one kind of pulley, for instance a fixed pulley or a compound pulley. the difference is pretty big because a fixed pulley is a wheel and axle that has a string with a hook on one side and a compound pulley is two wheels and two axles with a string up and down with a hook.
