Fingerprinting.

 Hello everyone welcome to or back to my blog.

Today i'm going to share about what we are doing in science. By the title you already know but for some reason if you don't, It's fingerprinting. 

These are the three things you'll need to do this.

Ink pad, Paper and if you have it a microscope.

This is the method:

1. Get a peace of paper and fold it up four times.

2. Get out your ink pad.

3. Put your finger on the ink pad and then on the paper.

4. Then last look though (your microscope) or at your fingerprints and see what fingerprint you have.

Loops: Loops are the most common type of fingerprint. 65% of the population has this type of fingerprint. 

Whorls: Whorls are the second most common type of fingerprint. 30% of the population has whorls.

Arches: Arches are the least common type of fingerprint. Only 5% of the population has Arches.

My fingerprint is a whorl here are some pictures of it.

Taking Care of Yourself

 Hello today i'm sharing and posting about what we have done in health this week.

Did you know that your heart is a muscle and if you be more active your heart will get bigger and stronger, aim for 150 minutes of fitness each week. This activity could be walking, biking or working out. 

Two things i'm doing at the moment is playing 3v3 basketball and also I use a app called fitness coach. Fitness coach is on ios and android. If you are not into sports you can go for walks around your block or if you are into it. You can go to a gym and your area and try new things.

Thank you for reading my blog. If you have time please leave a comment. Thanks Tom

pH Test Experiment

 Hello everyone today i'm sharing a post with you. 

This post is about what we did in science today. 

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

household chemicals.

Red Cabbage Indicator experiment
Materials

Red Cabbage
Beaker
Bunsen Burner
Pipette
Sodium Hydroxide
Hydrochloric acid
Test Tubes ( x5)
Paper towel
Test tube rack
Water
Steps
Chop up the red cabbage into small pieces. Place in a beaker and cover with a

small amount of water.
Bring the solution to the boil using a Bunsen burner and then turn off the heat.

Let it sit to cool down.
Pour the cabbage water through a paper towel into a beaker. The dark purple liquid in the

jar is the pH indicator liquid.

Suck up the indicator into a pipette.
In a test tube, use the cabbage indicator and the pH chart below to test the acidity of the hydrochloride acid and ammonium hydroxide.

Findings.

What is the pH of liquids.

Sodium Hydroxide
Hydrochloric acid

pH Indicators

 Hello today I and my class are learning about pH indicators. 

Definition: pH (potential of hydrogen) is a scale of acidity from 0 to 14 with 7
being neutral.
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. Alkaline 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:
Red Cabbage
Knife
Bunsen Burner
Beaker

Water

Method:
Cut the cabbage into small pieces.
Place the cabbage in the beaker and fill it with 50 ml of water.
Once the cabbage has boiled for 2 minutes turn it off and leave it to cool down.

Name another pH indicator used in a science lab?

Here are 4 Acids. Battery Acid, Stomach Acid, Lemon and Vinegar.

Here are 4 Alkaline's. Drain Cleaner, Bleach, Soap and Baking Soda.

By using red cabbage as an indicator we can determine what the pH level is of substances.

Sherbet

 Hello today i'm sharing my post about how to make sherbet.

Baking Soda also known as Sodium Bicarbonate. It has cleaning property and it help you with baking.

Here are ten uses for baking soda.

1. It helps Wheat rise.

2. It helps to cool down a burn.

3. It is in Mouthwash and it's what they use to whiten your teeth.

4. You can use it with deodorant.

5. Helps sunburn.

6. It's in air freshers. 

7. Kitchen Cleaner.

8. Help with carpet stains.

9. Clean foods.

10. Polish things.

Here are the ingredients.

1. Sugar

2. Baking Soda

3. Raro crystals 

4. Citric Acid

5. Tartaric Acid

Steps

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

2. Add the Raro crystals and tartaric acid together.

3. Add all ingredients together an place in a plastic bag.

4. Mix it well together and eat it. Enjoy!

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?

Cooking

 Hello we made cheese puffs.

Here is the recipe:

• 1 cup (125g/4.4oz) plain flour
• 3 teaspoons baking powder
• 2 cups (200g/7.05oz) grated tasty cheddar cheese
• 1 egg, beaten
• 1/2 cup (125ml/4.22 fluid oz) milk

Preheat oven to 200 C (392 F)
Gently mix all ingredients together in a bowl.
Drop large spoonfuls into greased patty tins or on a cold baking tray.

Bake for 10-12 minutes until puffed and golden.

I got the recipe from https://www.foodlovers.co.nz/recipes/nanas-cheese-puffs.html
