Acids

Hi Everyone! i our science class we are disccusing about acid  and red cabbage  experiment and  will tell you about it.

What is an Acids ?

Acids is a liquid that has a ph odf between 1-7 tastes sour and is used in batteries and in our stomachs.

What are the 3 examples of acids?

Lemons - Citric acid..

Vinegar - acetic acid.

Batteries - Sulphuric acid.

Aim: Toe make red cabbage ph indicator for use on different household chemicals.

Red Cabbage indicator Expiriment

Materials:

1. Red cabbage

2. Beaker

3. Bunsen burner

4. Pippete

5. sodium hydroxide

6. Hydrochoric acid

7. Test tube

8. Paper towel

9. Test tube rack

10. Water

 vinegar = pH 6.

 dishwashing powder = ph 12

.toilet cleaner = pH 11

Sherbet

 Hi  Everyone! in science class we are starting to discuss about sherbet and ten thing  baking soda do.

MATH

 KIA ORA! Everyone! In our hur 1 class we are doing math and in math we did addition, subtraction, multiplication and division. We did adding decimals, subtracting and multiplying  it and the task that I was doing is Integer  and it's a little bit hard for me   but it's good I learned something on it and I know how to do it now.

I hope you like it thank you for reading. Have a nice day!

Chilli tasting - Science

Hi Everyone ! in our science class we are discuss about chilli i will what a chilli is its a dish like a thick soup made with red beans, ground meat, onion, and tomato sauce, and flavoured with a spice made from chillies.

Chilli ghost peppers

Caroline reaper chilli pepper

6 hottest chillies in the world

• 7 Pot Douglah 1,853,936 SHU. ...

• 7 Pot Primo 1,469,000 SHU. ...

• Trinidad Scorpion “Butch T” 1,463,700 SHU. ...
• Naga Viper 1,349,000 SHU. 
• Trinidad Moruga Scorpion 2,009,231 SHU. ...
• Carolina Reaper 2,200,000 SHU. ...

Aim: to see which is the best way to cool down the hot chilli taste in your mouth when eating chilli

Hypothesis: I think that by using I will be able to remove the hot chilli taste from my mouth

Equipment:

1 Milk

2 Water

3 Coca cola

4 Tasting cup

5 Chilli

 

Summary and result:

Milk had a small effect on the chilli. after 3 minutes it took the whole taste away.

Coke had a small effect on the chilli. coke worked well after 3 minutes and removed the taste totally.

Water did not removed the chilli taste at all. after 3 minutes it removed the taste slightly.

Milk would be the most effective drink to use with spicy,chilli foods.

Conclusion

And milk could be solution when eating spicy foods - literally. that because milk helps your mouth handle capsaicin, an oily chemical compound in chilli peppers. capsaicin binds to receptor in the tongue and creates a burning sensation. casein protein found in milk can also bind to the capsaicin and wash it away.
