My Grade 4 Light Unit

Hello everyone! Today I will be talking about my first grade 4 science unit, light!

  • First, we studied about natural and artificial light! Let me share some fun facts:
  • Natural light means light sources created by nature. Here are some examples:

Sun, stars, fireflies, and fire.

  • Artificial light means light created by us. Here are some examples:

Lightbulb, glowstick, oil lantern, and candle.

After that, I tested my hypothesis that light travels in straight lines. here is my experiment:

 

 

Next we studied about luminous and non luminous. Here are some fun facts:

  • Luminous means something makes its own light. Here are some examples:

Sun, stars, anglerfish, and fire.

  • Non luminous means something doesn’t make its own light; it needs some help. Here are some examples:

Moon, certain street signs, reflective clothes, and cinema screens.

 

 

After that, we studied how light reflects. Here is my experiment:

 

 

We also learned about transparent, translucent, and opaque. Here are some things I learnt:

  • Transparent means that a material is see through. here are some examples:

Glass, drinking water, and thin ice.

  • Translucent means that a material allows you to see through, but the image is not clear. here are some examples:

tinted car window, thin jelly, and murky swamp water.

  • Opaque means that it does not allow you to see through. Here are some examples:

brick wall, concrete pillar, lead pencil.

 

 

Finally, we learned about refraction. Light travels slower in water than air, so it refracts, or bends, the light. here is a picture of me working on this:

 

 

Reflection Of Learning

I love science so far! We have done so many different (and fun) science experiments! I would love to learn about EVERYTHING!!!!!!!!!!!!!!!!!!!

 

My Personal Recount

One day in July, I woke up and looked at my clock. 3:00 am! Time to get ready, I said to myself. I was so excited to finally go to Florida!  After half an hour, we were all ready to go, waiting for my aunt to arrive. After four, we were almost at the airport! The car ride was very tense and excitement was in the air.

 

At the airport, we got our bags and went through security. My bag was randomly selected for a double check. The airport was quite busy, seeing that it was five in the morning. It took some time, but we were speedy and were on time for our flight.  I hate flights. They are soooo boring! This one wasn’t different. We flew through Toronto and arrived in the Bahamas. It was just like any other place in Canada, except way more tropical and hot.

 

After a few days of just shopping and chilling, we sailed to a place called Harbor island. The trip was long. Way too long! I was bored to tears and feeling sick. There, we rode huge waves on boogie boards at a beach with pink sand, visited reefs, and even had close encounters with green sea turtles, which are an endangered species! We were with them so much and once, Maia got bitten by one! I got a horrible rash, but overall, we had a blast!

 

After a few days here, we sailed back to the marina where we went to an enormous waterpark. At the waterpark, I went on a slide that was pitch black and went into a tank full of sharks! There was also a lazy river that wasn’t so lazy. There were rapids and giant waves! There was also a slide that was more like a rollercoaster!  I loved it! The trip was so much fun, but it had to come to an end. I had such an exciting trip! Thank you for listening!

Pioneer project

Here is some of the work I did before the project

This is some of my research

These are the original plans for the building

This is how it turned out.

 

Hey guys! It’s Nancy here! I just finished working for the day! It’s hard at this time of year. Summer is coming up soon so we’re struggling to get the weeds under control. All our tools are no longer good so we have to go to the shop. I got a deal on garden stuff so I won’t have to pay too much. It rained a lot so we couldn’t stay dry. This is our forecast: rain. Rain. RAIN. I hate rain. Turns out, the general store owner has some new mail so I’m out. Thanks!

This is my blog post from the point of view of a pioneer.

Pollution

Hi! It’s me again, today we’re talking about pollution and other issues with the environment. We will start by talking about pollution. Pollution is something that hurts the environment such as garbage, gases, and sewage. Us humans are making lots of gas from factories, cars, and even some lawnmowers! There’s also land pollution. Land pollution is caused by garbage being thrown on the ground also known as littering. Last but not least there is water pollution. Water pollution is caused by dumping sewage and other very gross substances in the water. I would love for pollution to disappear. But us humans are doing other things that damage the ecosystem such as illegal hunting. In case you don’t know, illegal hunting, also known as poaching is where people illegally kill animals. Poaching is especially common in  Africa where they kill elephants and rhinoceroses. These animals have Horns made of ivory which is a material that used to be used to make piano keys and other things. Trading ivory is illegal but people still do it. Now there’s logging. In case you don’t know, logging is where people cut down trees and destroy habitats. This is really bad because trees help turn carbon dioxide into oxygen and it is really important. 

Now here is habitat loss. Habitat loss is where an animal’s habitat is destroyed. Habitat loss can be caused by things like logging, global warming, and creation of new factories.Here are some of the ways you can help:

 

A sister of three

A Sister Of Three 

By noag18

 

Hi. It’s me. You may know me, you may not. The thing is, I am one of three sisters. It isn’t easy, you know. After all, I don’t have three parents! The thing is that I just can’t see my sisters upset, no matter how silly the reason. I have a fraternal twin and a little sister. My little sister likes soccer, my twin likes hockey, and I like gymnastics. We are all humans and humans make mistakes. When it comes to me and my twin’s names, people make a little too many mistakes. They never seem to get it right. Even my mother can’t seem to get it right! I love my sisters so much! I love my siblings and I hope you would like them too.

Beavers

Beavers are incredible animals and you will see why. I am going to share some facts about beavers.

 

1. Beavers are actually better at swimming than running. You can probably catch up with a beaver on land but once they enter the water you will fall behind.

2. Beavers make huge homes called dams but they actually live in structures within the dam called lodges.

 

3. Beaver teeth never stop growing. They need evergrowing teeth to cut down trees.

4. Beavers have orange teeth and they are technically made of metal. The teeth contain traces of iron and magnesium.

 

5. Beavers, as you know, are on the Canadian nickle.

1.Bikes Please! Riding your bike is not only good for the environment, but also good for you!

 

2.Who turned on the lights! To save energy turn off the lights if you are out of the room for more than 5:min. (Unless your little sis is in the room!)

 

3.3 Rs! Reduce, Reuse, and Recycle!

 

4.Don’t. Take. Long. Showers. Your mother has told you! Your father has told you! It’s not only rude to use up the hot water but it is also very bad for the environment!

All About Me

 

 

As said in the title of this document this is all about me! Now to get started. My favourite colour is neon pink, my favourite food is anything chocolate, and my favourite sport is gymnastics. I take lessons every Sunday. I have two sisters, two loving parents, a cat, a fish, and two snails.I love math, language arts, French, Hebrew, and reading. Basically I love school! I am not a picky eater because I know I’ll get dessert! My favourite way of writing is on an iPad because one, my hand doesn’t get tired and two, no mistakes! 

 

Thank you for reading!

My Cat Snowy

I have a cat named Snowy and I love her with all my heart. She does bite and scratch, but I don’t mind. She is such a good kitty. I don’t know how I could keep myself from going mad during lockdown without her! She is such an important part of my life. It was so sad when I had to leave her behind when I went to Florida. A few weeks ago she celebrated her first birthday! My sister is allergic to cats but it is not bad. Its spring! Can you blame her? I love my cat so much I would jump into my grandparents pool with nothing but a bikini just to see her! The point is, I love my cat, would you?
