I am a Year 7 student in the Uru Mānuka Cluster. This is a place where I will share my learning. Please note that some of it will not be complete, it will be my first drafts. Remember to be positive, thoughtful and helpful when you leave me a comment.
Put ten drips of universal indicator into the test tube
Add diffrent amounts of acid and base into the test tube
Watch what happens to the colour
Result:
(Not my picture but similar to what we did)
Disscusion:
1. What is an acid?
An acid is a chemical. It is any substance that in water changes ur taste. For example sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid lists).
2. " " a base
3.What happens when you react an acid and a base?
The reaction of an acid and a base is called a neurtalization reaction.
4. How do you measure acid levels?
You measure acid levels with pH. The range goes from 0 - 14 and 7 is the neutral. Anything below 7 is acid and anything above 7 is base.
I want to find out the best way to cool down your toung to cool down your toung after eating hot chilli.
Research:
(SO FUNNY ps:its not -_-)
Method:
Equipment
Hot chilli sauce (Carolina Reaper sauce)
Popsicle Stick
Drinks - Soda, Water, Milk
Timer
Instructions
Get your Equipment ready
Scoop up a drop of sauce on your posicle stick
Lick the hot chilli sauce and swerle it around your mouth
Start the timer
After 2mins, drink your drink
After another 2mis rate how hot it was after ur drink
Repeat experiment with diffrent drinks.
Results:
(Btw I didn't do the experiment cause i'm allergic to chilli so I am basically mixing in other peoples opinions)
Rating of hot chilli with each drink
The first chilli I did was without water and I am scoring it a 10 for burning. (Dying from the chilli)
Second Chilli with water(After Drink)
Chilli was still lingering on tounge and basically made it worse. (Water tasted disgusting)`I still rate it 10 for burning.
Thrid chilli with coke.
The burn got better after drinking the coke 5/10 because the bubbles and coldness cooled down the tounge.
Milk /10
Fourth chilli was 4/10 Milk fat cooling down the hottness and helping feel better. Dairy keeps you feeling better.
Disscussion:
Why does chilli burn your mouth?
In spicy food there are certain compunds that activate the type of sensory neurons called Polymodal Nociceptors. You have these all over your body including your nose and mouth. They are the same receptors that are activated by extreme heat. So when you eat something like a chilli peper your mouth feels like its burning because it sends messages to ur brain which thinks your mouth is burning.
Why did the milk reduce the burn?
That's because milk contains casin which helps break down and disolve capsaicin in chilli. Casin is like a
What is Capsaicin
Capsaicin is a part of chili peppers which is a chemical that
Stove, oven, microwave ( I am using a Bunsen burner)
Measuring cup (I am using a big Beaker)
Measuring spoon(tsp,)
Milk (200mils)
Pot or microwavable container
White vinegar
Paper towels
Stirring rod
Measuring cylinder)
Heat mat
Tripod
Gauze mat
Instructions
Get your equipment
Pour 200mils of milk into the beaker (Basically using milk powder)
Set up your Bunsen burner
Heat up your beaker with the milk on the Bunsen burner
Stir the milk with the stirring rod
Pour in vinegar with your measuring cylinder then continue mixing
Stir the mixture with the stirring rod until hot
Use a funnel to filter the curds and pour the mixture into the filter over top of a sink until all the liquid drains out( Stuff one paper towel into a funnel to make a filter)
I want to find out what happens when you put skittles in water.
Method:
Equipment
8x Skittles
Warm water
Petri Dish
Beaker
Paper towel
Instructions
Get your equipment
Put the skittles into the petri dish
Spread the skittles out around the sides of the petri dish
Don't need to but (Do not put the same coloured skittle next to each other (?)
Clean the beaker with the paper towel
Place the used paper towel on the table
Carefully place the petri dish on top of the paper towel.
GENTLY pour the water in the middle of the petri dish until it is half full
Observe what happens
Results:
Describe what happened
The colour on the skittles in the petri dish slowly dissolved heading towards the middle colouring the water. The colours were separated which made it look like a pattern.
Why did the colour move the way it did?
Because of the shape of the skittle.When sugar is moved into water it heads towards the middle. The colour comes out of the skittle and slowly spread out.
I want to find out what happens when gummy bears are put in liquids.
Method:
Equipment
Salt Water/Sodium Chloride
Normal Water
Sugar Water/Sucrose
Gummy Bears
2x Petri dishes
Marker
Electronic Scales
Safety Glasses
Instructions
Get your Equipment
Wear your safety glasses (IT IS A PRINCIPAL in the science lab).
With the marker, write your name and the conditions (dry, water, saltwater, sugar water) and the weight of gummy bears on the bottom of Petri dishes
Do the experiment.
Results:
Dry Gummy
Sugar Gummy
Water Gummy
Salty Gummy
Initial Weight (g)

Final Weight (g)

Difference
Gain 0.10g
Gain 2.37g
Gain 6.32g
Gain 2.14g
The water gummy weighs the most weight.
Why? The reason why is because gummy bears have small holes inside them. In water there are small molecules and Sugar/salt water have big molecules. Since gummy bears have quite small holes more little water molecules can come in and can expand. Sugar and salt water aren't able to do that because of their big molecules only a few could make it inside but they get clogged.
If not because the gummy bear absorbs the water.
