Investigation for the Isolation!

Dear students, 

During these two weeks of isolation we need to keep on studying science!! and of course....
we need to keep on investigating!!

I suggest.... to investigate why  we need to wash our hands with water and soap instead of water only.

Do not forget to follow the scientific method:

step 1: Ask a question.  Why are you doing this experiment? What do you need to investigate? step 2:  Hypothesis :This is an idea of what you think it might happens. All of them are correct. ALWAYS!!!  You can write as many as you like step 3: Materials.  step 4: Conduct the experiment . Explain how are you going to do the experiment. “ I introduce one piece of bread in a zip plastic bag……..etc.” step 5: Results:  analyse the result during the experiment in a table of contents.  step 6: Conclusion: Answer the  previous question (step 1) Check if your hypothesis was correct or not. What have you learnt after the experiment that you didn´t know before the project?

During the last week you´ve always heard about how important it is to wash your hands especially
now. But just because your hands look clean, does that mean they really are?

Experiment:

- Start with four pieces of bread

- The first piece of bread will be your control, which you will place in a zip plastic bag, using gloves.
Do not touch it with your bare hands!!  ( Control is something that is used for a comparison to check
the result of the experiment).

- The second piece of bread will be the one you touch with dirty hands. Make sure you do not wash
your hands for a while before you touch this piece of bread, and by all means..... touch the bread
all over with your hands!!!!

- The third piece of bread is the one you wipe all over the keyboard of your computer. 

- The last piece of bread will be the one you touch after you have thoroughly washed your hands.

In this photo you only have 3 zip plastic bags, but remember that you are going to need four: 1 plastic bag for Control  1 plastic bag for Dirty hands  1 plastic bag for Wiped on the keyboard  1 plastic bag for Clean hands

 You will  need to carry out the experiment for at least 7 to 10 days. So this could be an example of 
the table of contents you will need to use:

day 1	day 2	day 3	day 4	day 5
analyse the results of the day	analyse the results of the day	analyse the results of the day	analyse the results of the day	analyse the results of the day
day 6	day 7	day 8	day 9	day 10
analyse the results of the day	analyse the results of the day	analyse the results of the day	analyse the results of the day	analyse the results of the day

In order to do the experiment, you can use your science notebook, a white piece of paper or a
cardboard. Whatever is easier for you. 

Good Luck and enjoy the results!!!
