Health and Safety For science

 AIM:  

I want to find out the basics of health and safety for when you are in a science laboratory.

Research:

The most important Lab safety Rule

Follow the instructions! Whether it's listening to your instructor or lab supervisor or following a procedure in a book, it's critical to listen, pay attention, and be familiar with all the steps.

Know the location of the safety equipment and equipment:

In the event something goes wrong, it's important to know the location of the safety equipment and how to use it. As for the equipment, it's always a good thing to know where the equipment is.

DON'T EAT OR DRINK IN THE LABORATORY!!!:

Save your snacking for after your science period, not the lab. Don't eat or drink in the science laboratory.

Don't taste or sniff the chemicals:

Not only should you not bring in food or drinks, but you shouldn't taste or smell chemicals either it's just for your own health and safety.

That's all for my health and safety hope you enjoyed reading my health and safety for science don't forget to comment.

Coke And Mentos

Aim - I want to find out what will happen when you drop Mentos into a bottle of coke

Method

Equipment

- Mentos

- A bottle of coke

- Flat surface

Instructions 

1. Get your equipment

2. Take the lid of the coke

3. Put your bottle of coke on a flat surface

4. Put the mentos into the coke and sees what happenes

Result

Here is a video of someone doing a coke and mentos experiment. LINK 

Conclusion
I can conclude that if you add mentos into a bottle of coke It will make the coke erupt and shoot out of the bottle. 
Discussion

As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide that is still dissolved in the soda to cause more carbon dioxide to be freed and create even more bubbles, resulting it to erupt. 

What is a base?

 Acid has Hydrogen in it.

The strength of Acid is measured on the pH scale.

It goes from 0 to 14 

0-1 red

2-3 orange

4-6 Yellow

7 Green

8-10 Blue 

11-12 Indigo

13-14 Violet 

A base is an opposite chemical to an acid 

A base contains hydroxide (OH)

An acid and a base NEUTRALISE each other and make water 

Here is a photo of what it's like.

What is an Acid

 Name of Acid:

• Hydrochloric Acid
• Sulfuric Acid
• Nitric Acid
• Citric Acid 
• Formic Acid 
• Tartaric Acid 
• Phosphoric Acid 
• Acetic Acid 
• Formic Acid 

Formula Acid:

HCL

H2SO4

HNO3

H3PO4

CH3COOH

Where do you find acids? 

• Plaque Acid n your teeth.
• Stomach acid is Hydrochloric Acid.
• Battery acid is sulfuric Acid.
• Lemons and Oranges Have citric Acid.
• Vinegar contains Acetic Acid.
• Bee stings have formic Acid.
• coca-cola has carbonie Acid.

Thank you for reading my blog post I actually didn't know any of this stuff either and also my teacher said that we were learning year 11/12 work! which I felt very proud but it was mostly my teacher and his awesome way of teaching.🙌 His name is Mr. Stock so to all the teachers reading this umm.. sorry but... 😓

Eating hot chillies

Aim:

I want to find out if milk will help reduce the burn of the hot sauce

Research of videos 

The funny link 

The science link 

The experiment link 

Method 

Equipment 

1. Hot sauce 

2. toothpick

3. Stopwatch 

4. Water, coke, milk 

Instructions 

1. Get all of your equipment 
2. Dip the toothpick in the hot sauce 
3. Suck the hot sauce off the toothpick 
4. Start timing 
5. stop timing when it stops burning 

Results 

The time it took to stop the burning 

Just Chili: 50 secs Water: 12 secs Coke: 11 secs Milk: 7 secs this time is my friend's time.

Conclusion :

My friend told me that milk is the best thing to drink to stop the burning sensation 

Discussion :

Why does chili burn your mouth and why does milk stop it? 

when you eat a chili, the capsaicin is released into your saliva When this happens, it triggers these receptors, which send a signal to your brain, fooling it into thinking that your mouth is literally burning.

Blind Taste Testing

 Aim

I want to find out how we taste food

Research:

Taste buds have very sensitive microscopic hairs called microvilli, tiny hairs send messages to the brain about how something tastes and The average person has about 10,000 taste buds and they're replaced every 2 weeks or so.

Method

Equipment

• Unknown food 
• Blindfold
• A person with a tongue 

Instructions 

1. Get your equipment 
2. Put your blindfold on.
3. Block your nose 
4. put the food in your mouth and taste it 
5. Describe how it taste 
6. Release your nose and describe the taste 

Results:

Food#1 when I was holding my nose I couldn't taste it and it was juicy. When I let go I could taste it and it was crunchy 

Food#2 I couldn't taste it at first but then, when i took my hand of i, could taste bitter and sweet

Food#3 I couldn't taste anything even when I took my hand off it didn't taste like anything 

Food#4 at first I couldn't taste anything then I could taste the sweet lemon 

Food#5 I didn't taste anything at first then I could taste the sweet candy  

Food#6 I tasted the sugar

Food#7 As soon as I put it in my mouth I could taste the salt 

Food#8 as soon as I put it in my mouth it started to foam up and it was disgusting 

Food#9 as soon as I put it in my mouth it was so sour

Today I am going to be telling you about what we did in science.

The thing we did was we lit our hands on fire i will tell you what i felt,saw,smelt 

1. I felt pain
2. I felt excitement
3. I felt nervous  
4. I felt heat
