Question: How Do I Do An Science Fair Experiment On This?

I’m doing a science fair project on ‘which places have more bacteria on their bathroom door handles”
I was going to test my school
A shopping mall
Restaurant and my house
Now I don’t know how to do this please help!?
Thanks Michael Dervin you saved my life!

XD

Answer: Well, I would go to my local biology laboratory, be it in a Hospital, University or Local Clinic and ask for Petri Dishes in which you can grow Bacteria and Fungi, if you explain to them your project, they will give you the best dish.

Get a clean and sterile swab and swab the door handles and then rub the swab onto one of the dishes, quickly close & seal the dish and do not open it again. Do this for each location and then leave the dishes in a warm, place for a couple of days and you should see growth on the dishes. Record your results and NEVER open the dishes.

Once you are finished with the dishes, bring them back to the place you got them from for proper disposal,

Question: What is Related Theory?

I’m doing a lab report and in the template given to us, there is a section for ‘Related Theory’ it says ‘it may contain the explainations outlining the theoretical principals of the experiment, definitions, equations, etc.’ can anyone translate this into understandable english? the lab is on what was seen in pond water.

Answer: This is actually kind of tough, because the teacher might have a different way of defining this as me. But I think it’s just a section where you put the main ideas of the experiment. Any terms in your textbook on the subject that are in bold text might be well used here.

To be safe, I wouldn’t quite make it like a list of theories, key words, and big ideas. I would just try to do 2-5 simple sentences, stating that these ideas tie in, and briefly explaining how.

EX: In our experiment, we took ice, melted it into water, and then boiled it into a gas. This deals with the three states of matter, energy transferrance, and kinetic, potential and thermal energy. (obviously, a different experiment, but you get the idea).

Start with chapter/unit headings in the textbook, and see if ou can make little sentences with those that summarize what is going on.

Question: help on science experiment?

i have to design an experiment to test a enviromental factor on plant growth. i have to include a hypothesis, control, data table, and a graph… i do not kno wat to do so please help me
make sure i can do the experiment in a few hours
and i also need to be able to design with common household objects

Answer: for plant growth you need at least a couple days for most experiments try putting two plants in seperate rooms with no windows and the lights on, make sure both rooms have the same conditions, measure how tall they are then put a different kinds of music in each room after a while measure how tall they are again.
