Geometry Knowledge

This week and last week we have been learning about geometry and we had to make a slideshow about what we know about them. Our teacher listed some geometry words and we had to find out the information and write a short sentence about what they are. I did find some parts challenging and I kept moving forward even though its hard, so I finished it and it has seven of them, Line of Symmetry, rotational symmetry, translation, reflection, rotation, tesselation and enlargement. I am happy with it and I hope you learn something from my slideshow. Hope you like it and have a great day😄👍

Also, don't forget to comment on my post about what you liked about it and what you did not like about it.

Ice Experiment

Hello guys, today we were doing an experiment on making the ice stick to the matchstick. Is that possible? Yes, it is possible, me and my other two team members Hope and Anneleise worked together and tried making the ice stick to the matchstick. We also took photos from us lifting the ice with the matchstick. First, we had to gather all the stuff we need for the experiment than one of my team member went to fill the beaker with water cause it is part of the experiment. We put the ice in the beaker filled with water and got the matchstick. We each took turn putting the matchstick on the ice and then we added salt onto it. We added salt because of it dissolves and sticks the ice cube and the matchstick together making them stick like glue.

It was a fun experience doing this experiment and we enjoyed it so much and you can try it at home and get some help from the adult if you want to, it's not dangerous at all. It was tricky for Anneleise in the first place we started doing this experiment because it did not stick because Anneleise did not put the salt on the ice cube, she dropped the salt in the water, not on the ice. She tried her best and we all managed to lift the ice which was great and did not find anything challenging at all in this experiment and that is sad because I like challenges in the experiment. Hope you like my post and please comment about what you liked, hope you like it and have a great day😄👍.

Our main question:

Why do we sprinkle salt on icy roads?

Because the salt dissolves into the ice making it melt faster so the cars won't slip or have accidents on the road.

Here are the Photos of us lifting the ice with the matchstick

Elephant Toothpaste???

Hi guys, today we have been making an elephant toothpaste in science. We have been given instructions to follow and we had a lot of fun and exciting things to do. We had to be very careful with the equipment's because they were dangerous liquids that hurts your skin and poisonous ones as well. We had to wear gloves and safety glasses to keep our selves safe. We worked in groups of three and those people in my group were Skyler, Blake and myself.

We enjoyed what we have been doing and you could do this at home but you must have an adult with you to keep you safe from what you are doing. The gloves we used were soft inside but when we finished our experiment and had to wash it, it felt sticky. About our experiment when we mixed all/some ingredients together into a cylinder it smelt bad and I did not like the smell at all, But we all managed to reach the end without getting our selves hurt.

I and one other person took photos on the iPads but the photos needed to be transferred to our chrome books but did not work so sorry for not showing the photos. Here are the instructions to show you how to make it. Hope you like it and have a great day😄👍.

Elephant’s Toothpaste

Resources:

• Safety glasses
• A cylinder
• Rubber gloves
• A tote tray to protect the bench from damage
• 120ml Hydrogen Peroxide 6%  
• Dishwash liquid
• Dry yeast
• Food colouring
• Funnel
• Tablespoon
• Beaker

Procedure:

1. Put on your gloves and goggles.
2. Put a tote tray on the bench and put your cylinder in the tote tray, with the funnel in the top.
3. Ask the teacher to pour the hydrogen peroxide into your cylinder (via the funnel).
4. Add 10 drops of food colouring to the cylinder (via the funnel).
5. Add a tablespoon of dishwashing liquid to the bottle (via the funnel).
6. Swirl your cylinder around to mix everything together.
7. In a beaker, mix a tablespoon of dry yeast with 3 tablespoons of warm water and stir for 30 seconds.
8. Pour the yeast mixture into the cylinder (via the funnel).
9. Stand back and watch the chemical reaction!
10. Pour the mixture down the drain afterwards and wash out the cylinder.

Scientific Explanation (How it works):

The yeast and water mixture acts as a catalyst - something that speeds up a chemical reaction in another substance while remaining unchanged itself. When you add this to the cylinder it makes the hydrogen peroxide break down into oxygen and water. The dishwashing liquid traps the oxygen in bubbles to create the foam. Just a small amount of hydrogen peroxide will create a lot of oxygen, so you get loads of bubbles - making your ‘toothpaste’ almost explode out of the cylinder.

Super Slushie's

Hi guys, for four or five weeks before we have been doing business and enterprise for raising money for eight camping trip. For our business, we are making slushies and it will have four flavors. Lime, Lemon, Rasberry, and Cola, we had to make/decorate our posters so we can put it around our school. Maybe we will stick it around our school, also forgot to say that in my group are four people, Sahana, Ruby, Skyler and myself Ranit.

Skyler is working on our big poster and is doing the hard work making the posters look pretty. Ok so after that we had to write in our document what we have achieved and we are happy with it. Thanks for reading my blog post and have a great day😄👍.

Testing for Simple Sugars (Benedict's Test)

Today at science we have been testing for simple sugar ( benedicts Test). We worked as pairs and first, we took out a bunsen burner and set it up on fire, after that we took photos.

Next, we took out a test tube and added sugar. we added benedict solution, after that, we swirled the mixture in the test tube and over the flame, blue flame. I gave it to my pair and he dropped it on the floor, it was disappointing what happened 

Hope you like it and have a great day :)

Aim

I want to find out how to test for simple sugars.

Simple sugars are carbohydrates that are quickly absorbed by the body to produce energy. They are also classified as “simple” because they contain only one or two units of sugar or saccharides. Also referred to as simple carbohydrates, these sugars are found naturally in a variety of foods that we consume daily.

Equipment

• Safety glasses
• Bunsen burner
• Test tubes
• Test tube tongs
• Benedict's Solution
• Food sample

Method

1. Place about 2mL of the food sample into a test tube and then add 5 drops of Benedict's solution and 5ml of water
2. Gently heat the test tube over a blue flame.  DO NOT BOIL!

Results

A positive test for simple sugar results in Benedict's Solution changing from a blue colour to a yellow colour to an orange/red colour.

Conclusion

The chemical’s, sugar and benedict’s solution turned from blue colour to light orange colour as we mixed it over the blue flame.

Extra for experts

Two different types of sugar exist: simple and complex. Complex sugar takes longer for your body to break down and is healthier for your body. This type is found in natural carbohydrates such as whole grains and fruit. On the other hand, simple sugar is broken down by your body quickly and causes energy ups and downs. This type of sugar includes refined and processed sugar found in table sugar and added to many sweets. Consuming an excess of simple sugar comes with numerous health problems

• Cereal and flavoured drinks have simple sugar to get you hyped.
• At what times of the day may you need simple sugars? Fitness, Midday
• Do you think that it would be wise to eat simple sugars before bed? No Why/why not? Because it will keep you hyped at night.

HATW-Hover All The Way

Hello guys, since this week and maybe last week too we have been working on making our own advertisement. Advertisements are like ads that come in newspapers, iPads, iPhones and other devices and articles. We enjoyed it and there was a bit of a problem with my buddy but I can't tell you that. Anyways we chose to do a newspaper advertisement. I finished it and I am happy with what I have done. Hope you like it and have a great day😁👍.

Respecting Places/Property

Since this term we have been doing philosophy about respect things, there are four things to respect in HHS. Respecting people, places, property, and beliefs. We had to choose one and my teammate chose places. After that we made a slideshow about how to respect these places, we got mixed up with property and places so we had to put them together. We finished it but haven't done much in it because we had no idea what to put in it so we are happy what we have done. Hope you like it and have a great day😄👍.
