Making a periscope.

Recently, I made a homemade periscope and I wanted to share how I made it. For those who do not know how what a periscope is, it is an object that enables you to see above you without having to look look yourself. Normally, submarines include them.

What you will need:

  • Cardboard
  • Coloured strong tape (colour of your choice)
  • CDs
  • Bucket
  • Hot water (but not boiling) 
  • Paper template
  • A sharp knife
  • Very strong glue


Instructions

1. First, find a template online and print it out.
2. Cut the template out as you want it to be.
3. Then, trace the outline of the template on the piece of cardboard.
4. Next, cut it out.
5. Fold the cut out cardboard as the template shows to do or along the lines.
6. Get the two CDs and, with the knife, cut out rectangular pieces (mirror).
7. After that, glue the cardboard and mirrors (at a 45૦ angle) to make a periscope baseline.
8. To secure it, add the colourful tape all around it.
9. Finally, decorate it and it is finished.

It should look like the picture below. Thanks for reading and do not forget to stay tuned.

How the periscope works

 The light from the surface you are looking at bounces into the periscope and bounces off the mirror at a 45૦ angle and hits the oter mirror at another 45૦ angle and into our eyes.

Very cretive stayathome project. Well done. Although it looks simple but actually lots of science you can learn from it such as the properties of light.

My book review

Image
A few weeks ago, I created a book review on request for it to be posted on a magazine . I chose to do it on the Boy of the Back of the Class. Here is my review.↓ Introduction The Boy At the Back Of the Class is a great book by Onjali Q. Rauf because it reveals the hardship of people escaping the war in Syria and a strong connection between two people. Summary A refugee boy came to a school where the narrator and her best friends go to. The narrator became friends with Ahmet (the refugee boy) and Brendan-the-bully was being mean to him so they had a fight. Ahmet won and so Brendan got revenge by putting a can of baked beans into Ahmet’s red bag. He tries to wash it off but the smells and stains stayed. The narrator learned more about Ahmet’s background story and how he got into the school and country. Ahmet and his family were running from a war in Syria and they all got separated. Unfortunately, Ahmet’s cat died whilst going on a boat to Greece. They had to move to many differe

Making Harry Potter Monopoly

Image
Me with the game Two days ago, my mum had a fantastic idea to create our own Harry Potter Monopoly to play as a family. 😀We printed the paper for the board that I cut it out extra carefully. The next day, we got some unused cardboard and turned it into the gameboard. We printed the money and the title deed cards and cut them using the slicer. We used a recycled box to make the place to put the game and figures inside. Then, we printed the bottom for the box and stuck it on. After that, we wanted to print the top of the box but we unfortunately had no ink left!😞 At night, after we had iftar and salah, we played the Monopoly and it was AMAZING!!! We all were so into the game that we played until midnight!😅A few days later, the ink finally arrived and we printed the top of the box to complete everything. The game turned out to be spectacular. Instead of regular chance cards and chest community, there were potions and spell cards. E.g. One of the potions cards said to go directly

Pizza Pizza

Today, my mum suggested my sister and I make 3 mini pizzas for lunch. She also asked my brother to make brownies with her. We all woke up and opened our home school (I knew that I would have a lot of fun today because we had so much fun yesterday).  I decided to draw a greyscale (black and white), shaded picture of my blue, metallic hydroflask. I think it looks very realistic. Share what you think of my drawing in the comments. After that, my sister and I made the pizzas. Me with my drawing. I had to be very careful with the shading and I really did not want a single line out of place because I want it to look neat. I also put the shadow of my bottle to make it look even more realistic. Instructions to make a mini pizza Serves one person. 1.First, preheat the oven to gas mark 5. 2.Second, mix in a cup of flour with a half-cup of water (ratio from flour to water is 2:1). 3.Flour your surface and knead the dough on that surface. Place the dough into a circular pa
