Sherbert

Baking Soda is also known as Sodium Bicarbonate.Due to its abrasive and cleaning properties it is used as a raising agent in baking, as a household cleaner and in a number of other ways.

My 10 uses of baking soda are:

  1.  Treat heartburn

  2. Mouthwash

  3. Soothe canker sores

  4. Deodorant

  5.  May improve exercise performance

  6. Relieve itchy skin and sunburns

  7. May slow the progression of chronic kidney disease

  8. Neutralize fridge odors

  9.  Air freshener

  10. Kitchen cleaner


Making Sherbet

We need to write down our equipment and the steps we will go through to make our sherbet.

Once we have completed the materials and steps we can make sherbet.

While you are eating your sherbet you can answer the 5 questions at the end.


Equipment:

  1. sugar

  2. Baking soda

  3. Raro crystals

  4. citric acid

  5. tartaric acid

Steps

1.Add the baking soda sugar and acid together in a bowl

2. Add the Raro crystals and the tartaric acid together

3. add all the ingerdeints together

4. Mix it well together and eat it. No comment

Recipe:

1 teaspoon of powdered drink crystals (eg Raro)

1/4 teaspoon of citric acid

1 teaspoon of Icing Sugar

1/4 teaspoon Baking Soda.

Findings:

1. Which two ingredients in the sherbet are involved in the chemical reaction?

2. Which ingredients are not involved?

3. Can you think of any other chemical reactions that might happen in the kitchen?

4. Which ingredient is an acid?

5. Which ingredient is a base?

Introduction: Acid Rain video

.......followed by this video on acids.

Watch this video: What makes something acid?

Answer the questions: Properties of acids

What makes something acidic?

What are 3 examples of acids?

What are some natural acids?

What is the pH scale?

What does pH stand for?

p stands for __ph____________.

H stands for _____________.

What is the most famous indicator?

How many numbers are there on the pH scale?

What are the numbers for an acid?

What numbers are for a base / alkaline?

What flavour are acids?



Aim: To make red cabbage pH indicator for use on different household chemicals.

Red Cabbage Indicator experiment

Materials

  1. Red Cabbage

  2. Beaker

  3. Bunsen Burner

  4. Pipette

  5. Sodium Hydroxide

  6. Hydrochloric acid

  7. Test Tubes ( x5)

  8. Paper towel

  9. Test tube rack

  10. Water

Steps

  1. Chop up the red cabbage into small pieces. Place in a beaker and cover with a small amount of water.

  2. Bring the solution to the boil using a bunsen burner

  3. and then turn off the heat. Let it sit to cool down.

  4. Pour the cabbage water through a paper towel into a beaker. The dark

  5. purple liquid in the jar is the pH indicator liquid.

  6. Suck up the indicator into a pipette.

  7. In a test tube, use the cabbage indicator and the pH

  8. chart below to test the acidity of the the hydrochloric acid and ammonium hydroxide.

Findings.

What is the pH of liquids.

  1. Sodium Hydroxide

  2. Hydrochloric acid

pH indicators

 

Definition: pH (potential

of hydrogen) is a scale of acidity

from 0 to 14 with 7 being neutral.

pH Explained

All solutions have a pH. Acid solutions, have lower pH. Alkaline solutions,

have higher pH. Substances that aren't acidic or alkaline

(that is, neutral solutions) usually have a pH of 7. Acids have

a pH that is less than 7. Alkalis have a pH that is greater than 7.


Write down the 15 substances

from the diagram and beside them list their pH level.

List them under 2 headings. 1. Acidic 2. Alkaline


Experiment: Red Cabbage indicator.

Equipment:

  1. Red Cabbage

  2. Knife

  3. Bunsen Burner

  4. Beaker

  5. Water

Method:

  1. Cut the cabbage into small pieces.

  2. Place the cabbage in the beaker

  3. and fill it with 50 ml of water.

  4. Once the cabbage has boiled for 2 mi

  5. nutes turn it off and leave it to cool down.

  6. Once it has cooled remove the cabba

  7. ge leaves and use the red water as an indicator.

Complete the quiz below:

The ph scale ranges from what numbers?

Name 4 substabces that are acidic?

Name 4 substances that are basic?

Name another pH indicator used in a science lab?


By using red cabbage as an indicator we

can determine what the pH level is of substances.

Cooking

During cooking we learnt how to  turn on a oven and how set up everything i was really fun because we got to learn something new. my class and I made cheese toasties which were really good here's a tip wash your hands often to prevent form bacteria and do not touch the tables when they have just been cleaned.

                                            I hope you enjoyed my blog post





my logo

 This week we have been learning how to create a logo and a brand for out future business enterprise that will be starting next week, we had to come up with a brand logo for a pretend business and I choose hot choclate mostly because I can't live without it, we had to choose a font and a co lour palette to make our logo, I found it pretty easy to make a logo I used Google draw to make one and I made it in about 5 minutes, it was pretty fun though. Here's my work

chilli

 Aim: to see which is the best drink to  cool chill on your tongue

1.THE FIRST CHILI'S WAS A CONVERTED POSTAL STATION IN DALLAS.

2.THERE IS ONE PHOTO HUNG UPSIDE-DOWN IN THE DINING ROOM OF MOST CHILI'S LOCATIONS.

3. FOUNDER LARRY LAVINE WAS INSPIRED BY A TEXAS CHILI COOK-OFF.

 4.THE FIRST CHILI'S LOCATIONS ONLY HAD ONE TYPE OF BEER: SCHLITZ.



5.CHILI'S SELLS 60.4 MILLION POUNDS OF FAJITA MEAT A YEAR.
  
Method:

1 Get your equipment ready
2 Get a drop  of hot sauce on your Popsicle stick
3 lick the hot sauce 
4 start the timer
5 after 2 mins,drink your drink
6 after 5m how hot is your mouth
7 repeat the experiment but with a  different drink

The frist chili i did was without water and i am scoring it a 0 for burning.
The second time, i had water and after four 4mins  I scored it a 1 out of 10.
The thrid time,I had coca-cola and I scored it a 2 for burning after 4mins.
the fourth time , I had milk and I scored it 3 for burning left over
