want is a bases?

A substance is acidic if it has a pH level of 0 through 7, where 0 is the most acidic. A substance is basic, then, if it has a pH level of 7 through 14, where 14 is the most basic. If a substance has a pH of exactly 7, it's neutral. This means it has equal amounts of hydrogen and hydroxide ions.

in chemistry, pH is a scale used to specify the acidity or basicity of an aqueous solution. 

In chemistry, neutralization or neutralisation is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution

 

want is an acid ?

 Hydrochloric Acid

sulfuric acid 

nitric acid

Kids Definition of acid (Entry 2 of 2) : a chemical compound that tastes sour and forms a water solution which turns blue litmus paper red.

red cabbage indicator

 aim 

• 1 head of red cabbage
• Sharp knife
• Pot to boil water in (or blender)
• Strainer or colander
• Glass bowl
• clear cups or glasses
• household liquids to test (vinegar, baking soda, juices, soaps, bleach, ammonia, and anything else you want!)
• Something to stir with

 

1. Take your red cabbage and have an adult help you cut off about 2-3 cups (the amount doesn’t need to be exact, the more cabbage, the more indicator you will get).
2. Have an adult boil a pot of water and place the cabbage pieces in. Bring the water back to a boil for a couple minutes. Turn heat off and let sit for at least 10 minutes. Again, there’s no magic number, you just want the water to be a reddish-purple color. (You can also place the cabbage in a blender with water).
3. Strain the water out into a glass bowl and let cool.
4. Once it has cooled, pour some into clear cups or glasses and add different liquids to test. 
5. Gently stir or swirl the solution and see what happens!

(Be careful about mixing household cleaners together, as some combinations may produce harmful fumes. Only test one substance at a time.)

makeing sherbet

 aim

i want find out how  to make  sherbet

• 1 tsp citric acid
• 2 tbsp icing sugar
• 3 tbsp jelly crystals (any flavour you like)
• 1 tsp baking soda

Gather your ingredients. 

Measure ingredients into a small bowl. 

Mix them well.

Enjoy!

FUN FACT

When you mix baking soda  with citric acid some of the atoms recombine into CO2  and as this gas escapes the sherbet it makes it fizz and bubble up in your mouth.

 Why do you think tiny bot made such a mess? 

Code - he wasn't coded to clean.

Can you think of any other instructions that the robot misunderstood?

Cleaning and cooking.

How did tai and anna feel about their mother waking up?

They felt scared. There is a picture of them being scared.

How did mum feel? How do you know this?

Mum was angry. Mum yelled at them. 

What will happen in chapter 2?

Maybe the tiny bot will make another mess.
