|
Dish wash liquid and bleach

Put them both in something
|
With a small amount nothing with happen but more when inhaled burns and irritates
|
It make another gas that is bad for the human body
|
Bleach and vinegar

You should not do it because it can damage the lungs with a gas
|
This makes the same gas
|
Lemon and vineger

But the ingredients in a bottle and but a balloon on top
|
It will blow the balloon up with some type of air

Extension:
What is another experiment you could do using chromatography and how would you do it.
Title;Leaf color
Aim: why leaves change color in autumn
Materials:
Isopropyl alcohol
filter paper
3 cups
scissors
leaves
Process:
1.Cut the leaves up in to little strips in a cup
2.cover the leaves in isopropyl alcohol

What is that white powder
Today you will be a forensic chemist.
A bag of white powder has been confiscated by the airport customs. You need to find out what white powder it is?
Aim: To learn about the makeup of different white powders.
There are a number of different white powders in our everyday life. Some of these are harmful and others are not. Test the four white powders listed to see which one has been found at the airport.
Here are some examples of everyday kitchen white powders.
Flour
Cornflour
Sugar
Salt
Baking Soda
Baking Powder
Icing Sugar
Tartaric Acid
Citric Acid
Gluten Free flour
Materials

5. water
6. lodine
7. vinegar
Upload a photo of each powder.
1. Cornflour
2. Baking Soda
3. Salt
4. Sugar
On the black cardboard using a microscope you need to record what you see. You will be given a small amount of 4 white powders on your cardboard. Look at them under your microscope and record what you see.
Do not mix the powders or taste the powders.

Today we looked at what happens when you mix some chemicals with white powder you can find at home. the vinegar mostly made them go grey and fizz. the water does nothing
and the iodine stains it
