Setting Our Hands on FIRE!

 Welcome,

Today I'm going to be telling you my experience by setting my hands on fire. People might say it dangerous and it's scary. And they are right. But at least give it a try. So let's get into it. Before we set our hands-on fire we have to go through safety rules. 

We need safety glasses. Listen for the intrusion if you want to get rid of the fire and change your position to a stop. Sadly I don't have a video of it so it's hard to finger out what I'm saying. Anyways here are the things you need to set your hands on fire.

First up get safety glasses and wet your hands in water up to your elbow. Next scoop some bubbles made from gas. Make sure you get lots of bubbles just in case. Next, you stand straight and move your hands away from your face. Then you get someone to light the bubbles on fire and enjoy. It'll hurt like fire but you can stop whenever you want. If you feel like stopping, stop. 

Here is the video

I hope you enjoy. I got nothing much to say so goodbye.

Fast Reaction

Welcome To My Blog,

Yesterday and today we practiced our reaction time to see who has the fastest. And before we tried it I knew I already had a fast reaction time. Reaction time is how many seconds it takes for you to react to something. Like when something falls you might have a quick reaction to running and catching it. Some people would stand still and think about what to do then it drops. 

Getting a fast reaction time is not easy. You have to think fast. You know a common phrase, "Think fast" then they throw a ball at you or something you could catch. I usually catch it or try but miss it. But it does help your reaction time. The more you practice the faster you can think. 

So first I wanted to drop the ruler on Khiel's hand to see how fast he can catch it. I planned to try and distract him then drop it at an unsuspecting time. Like I talked to him about when I'm going to drop then I dropped it than catch it. Then quickly I dropped it again making him react really quickly before it falls. Sadly he didn't react quickly so he caught it on 2.9 or 30.

Here is my fastest reaction time on a reaction test.

Growing Bacteria and Fungi

 Welcome Viewers to my blog,

Today I've grown some Bacteria and Fungi. We used some agar jelly inside the petri dish. We have to find something to create bacteria like fingernails or your hands. For my first one, I used my phone & phone case, the top of a very old dirty bucket, a Chromebook, and a science desk. All of them are really dirty and haven't been cleaned in a long time.

Here is a video of me explaining what I've made.

Taste Test

 Welcome Viewers to my blog,

Today I'm going to be sharing with you my science experiment. The experiment was easier than I expected. We have to do a taste test. We have to identify what food it is. But we have to do it blindfolded and with our nose block. 

The method we used was,

Let someone cut up the food for you without you knowing what it is.

Get a partner to feed you the food.

Blindfold yourself and block your nose. 

Guess what it is.

It's your partner's turn.

After when they finish your done.

As you can see it was really easy. But guessing what is the food is harder than you think. But when I tried the apple was the easiest thing to guess. Maybe because the flavour is unique or I ate too many apples and remembered the flavour. 

Next, we did a tongue taste. We got three substances and put them on a taste buds area. Then after when we put on a tasting area we have to guess which taste buds is which. Funny story, I put the sugar in the front of my tongue and it was really sweet but really sour so I stood up and walked around for a bit.

Here is the Graph on how many people got a taste correct.

Pocket Rocket

 Welcome Viewers to my blog,

Today we are going to talk about my last experiment. The science wasn't that complex and it was pretty easy. We got a little small cylinder to put the vinegar inside. Then we got the baking soda in another glass jar.  We put the baking soda in another glass gar because it was going to have a chemical reaction with the baking soda.

The cylinder must have a lid so it could launch up. So first we quickly got 1 teaspoon of baking soda. We put it inside then we turned it upside down. He ran back because we didn't know what was going to happen. Then. Pop! You could see the surprised face of most of them. 

Here is a video of us launching the first pocket rocket. Everyone was surprised. Sound Warning. Camera Shaky.

Science Indicators

Welcome Viewers to my blog,

Today we are going to be talking about an experiment that me and my friend Khiel did. We were doing an experiment when we add acid, alkali and water/neutral to something like cranberry juice, tea and turmeric powder. We also got a chance to try out the universal indicator. 

So we tested cranberry juice with acid, water and alkali. First, we put acid in cranberry juice. It didn’t change the colour much because it’s already red. It just got a little bit darker. It’s not that noticeable. Next, we did the water. We added water to the cranberry juice and we overfell it a little bit. The cranberry juice was a little bit lighter than before, like when you add water to basically everything. Next, we added alkali to the cranberries. This one was a noticeable change. It got really dark. It kinda got 2x darker

Next, we tried tea. The tea smelt and looked really good. Again when we added the acid it still looked the same. Then we added some water and it did the same thing. It just made it a little lighter like how you add water to most substance. Then we added alkali and surprise surprise it became a darker colour.

Next, we did it with some turmeric powder. First, we were hyped up so we added water first. Because we saw some group that added water first then it looked like orange juice. We quickly went to go and get some water and added it. We moved the test tube around and mixed it. It turned orange then we put it down. Next, we went and added Akali. We mixed it around as it turned dark orange. Then we added some acid. It kinda turned it into a lighter colour for some reason.

Then we wanted to try out the Universal Indicator. First, we added a couple of drops of acid, then water then akali. We got out the universal indicator and added a couple of drops in each one. The acid started turning red as the water turned green. The alkali turned into a dark blue colour. 

Red - Acid

Green - Neutral

Blue - Akali

Gummy Bear Osmosis

 Welcome Viewers back to my blog,

Today we are going to be talking about an experiment I did with my friends Khiel and Lucas. First, before we started our experiment we had to predict what will happen. Our science teacher Mrs Wheeler said there is no wrong in guessing what will happen. 

I wrote that the gummy bear will absorb the saltwater, sugar water and water. After when it absorbs it I'll and grow in size. When we started our experiment we first got some saltwater and put two gummy bears in the saltwater. Then we went and got some sugar water/sugar dissolved in water.  Then we got some plain water that has been filtered. We got the gummy bears and put them in. We also got 2 gummy bears that were not in any of the water. We took some pictures of the gummy bears.

We left our gummy bear for about 24 hours and when we checked it people thought it grew in size. But it just looked like it grew. When we got our gummy bears we observed them and noticed that the water one broke it in half. I took off the lid to feel them and they were really sticky. They were also fragile so they break easily when you touch them. 

After our experiment, we watched a video of someone doing a gummy bear osmosis experiment. Their one grew in size because they left it out for only about 15 minutes. Our one burst because of the water so it couldn't grow in size.

Famous Women Scientist - Maryam Mirzakhani

Welcome Viewers to my blog,

Today we are going to talk about one famous women scientist. I picked Maryam Mirzakhani as the women scientist I'm going to be researching. I picked her because she is a mathematics and she is really interesting in general. 

Maryam Mirzakhani was an Iranian mathematician, she was a professor of mathematics at Stanford University. She research topics about the Teichmüller theory, hyperbolic geometry, ergodic theory, and symplectic geometry. 

She is famous because in 2014 Maryam Mirzakhani was the first woman to be awarded a Fields Medal. In her life, she had some misfortune and in 2013 she was diagnosed with breast cancer. In 2016, the cancer spread to her bones and liver.  She died on 14 July 2017 at the age of 40.

Bunsen Burner

Welcome Viewers to my blog,

You might have seen my first blog of 2021 now this is my second. Today I'm going to tell you some of the safety rules for the Bunsen Burner. So today I lit a match for the first time because my parents never made me light up a match before. Anyways lets into it.

First, we are going to be talking about safety rules.

1. If you have long hair tie it up into a bun just in case something happens to it. 

2. Wear safety glasses to protect your eyes.

3. Don't eat or drink in the lab.

4. Wear leather shoes so if you drop acid it won't get to your feet instantly.

5. Stand up during a practical so you can move back if something goes wrong.

6. Put any bags or jacket under you desks or on your seat.

7. NO RUNNING in the lab.

8. Check if all the gas is off.

9. If anything is broken tell the teacher or you'll be in bigger trouble.

Here are the steps for lighting up your Bunsen Burner. 

1. You set up your Bunsen Burner to a rubber tube.

2. Get your fireproof mat or someplace to put the Bunsen Burner because it's going to burn the thing it's under.

3. Place the rubber tube into a gas dispenser or something that can produce gas. 

4. Make sure the air hole is closed and light your match.

5. Pump up the gas and put you match over the top of the Bunsen Burner.

6.  Move it around until the gas gets caught on fire.

7. Done your finished you can open the air hole if you want hotter flames or close it for the safety flame. The safety flame will still burn you but you can see it and its less hot than the blue flame.

Here is what the Bunsen Burner Parts

Bunsen Burner Flames

Questions	Air Hole Open	Air Hole Closed
Colour Of The Flame	The colour when the air hole is open is blue.	The colour is red
Describe The Flame	The flame is dark blue. The other flame is invisible to the naked eye but you can only see the blue flame. The blue flame is really hot way hotter than the red flame.	It’s red and really easy to see. But it produces lots of smoke and the smoke smells bad.
Is It The Safety Flame	No, the blue fire is not a safety flame. First of all its really hot, second-most of the fire cannot be seen through the naked eye.	Yes, the red flame is really easy to see and less hot than the other.
