Tip 10: The jobs
If your group has time and patience...
List the jobs, then tell everybody in the group to order their favorite job to the least. When everyone is done, tell them to say out their first choice, then the second, the third etc. Once that is done, start giving out the jobs. If more than one person wants to do the same job, ask if it's ok to chose their second choice as their job. However, if their second choice is taken, you must play around a bit until everybody's happy. Therefore, this is method is recommended for a group of 2-4.
If your group is inpatient...
Tell them that they have to switch jobs during the experiment, so each person gets at least one time each job. This can be for any amount of people. It's just time that is important here. If there is not enough time, not all jobs could be done by each person.
The universal rule to combat this situation...
Tell them this is just an experiment. It is not a life time carrier. If any of them refuse (very strongly), let them be it. It would be worse if the whole experiment would be interrupted by this. It could even lead to failure if you are not careful.

Tip 9: Quoting
A few months ago, I have produced a 7 page lab report which contained a lot of quoting (Topic was a ballon rocket compared to real-life situation) Using what I know about force and gravity, I quoted what Isaac Newton said (For those who don't know, Newton "discovered" gravity). So I said something like " The object would stay moving/still unless a force is reacting to it." On the same time, I added something the teacher told me in class.
When the teacher saw this, she was impressed. My guess is that she was impressed because I paid attention to her class (I always do...by the way).
To conclude this, use quotes from textbooks, scientist whatever. Use it. It may add score to your research skills.
Tip 8: First things first
Don't get what I mean? Well, it's like having a boyfriend or girlfriend. It's impossible to have a good replationship unless you spent time toegether. Same applies for lab reports.
However, before you start writing your lab report, be sure you got all the data and nothing is missed out. Otherwise, when you noticed you screwed up the info, you might as well start again.
So heres my tip (And probably what other teachers hope for as well): Start as soon as you can, because that is when you remember every single detail of what happened in the experiment. Thats one thing that notes can't assist you.

Tip 7: Find out what your teacher wants
What you should do is to at least attempt each part of the Lab Report. They don't have to be perfect, but at least an attempt is good enough. But to make your teacher happier, work a little bit harder on the part he/she focuses on. In that way, she would be more impressed.
Before even trying to impress your teacher, first find out what he/she focuses on. So just work equally on all parts on the lab report when you meet your new teacher. Gradually, lab report by lab report, you will begin to notice which oen she focuses on the most. Sometimes it could be the parts where she writes the most comments on. But don't mistaken yourself, if you now you do bad on that part, the comments aren't there for nothing.
After about 2-4 Lab Reports, you should have identified her interest. If you don't see any, it might be that your teacher doesn't have a special focus, so you are pretty safe.
Tip 6: Method/Procedure guide
Anyways, if you don't know how to write a Method/Procedure, you can think it this way. Think you are writing for someone who is a complete idiot. He/she also wants to do the experiment, so now you need to write down the steps very clearly to him. He/she then then able to redo the experiment you done.
A few little tips:
- Use diagrams to help you think, but don't include them inside the actual Lab report.
- Give sample results and tables
- Use numbers to represent your method like step 1, step 2, step 3....rather then using bullet points or just in paragraphs. Since quite a lot of people forget where they left off when interrupted.
- When saying "Set up the experiment", you should say how to set it up. They didn't see you doing it (Unless you drew a diagram on how to represent your experiment)
- At the end, you should say what to do with the data. Draw a graph or plot it inside a table. I don't know. You decide.
Tip 5: Adding real life situations
But here is the fun part. You can make anything up. So if I ask "Can you determine a real life situation of two objects droppping down from the same height?" So now you can make something up like "A fat alien and a thin man dropping down. The fat alien would hit the ground first." So be creative.
In the same time, you can make a digram/picture to explain your real life situation as well. So then you can use your pen to draw an alien and a man falling. Remember to give data, include them in your labels.
So the data you can add is the weights of the alien and man. Then linking with the Hypothesis, explian why the alien would hit ground first.
Tip 4: How to write a good Evaluation
- A fair test or not?
- Explain why it is(n't) a fair test.
- What could be done for future experiments?
- Was the data you collected precise?
- Was the data you collected reliable (are you able to trust it?)
- Were there any problems?
- If there were problems, how did you solve it?
Theses things should be manditory in any evaluation. However, if you or your teacher wants you to add something extra, do what they say! This info inside the evaluation may lead you to a good score!
Tip 3: Drawing a diagram
Although it is not mandatory (meaning not needed), it gives a teacher clearer idea on how the experiment is presented. Especially when doing an Inquiry Lab, where you can't really explain on how to set up the experiment. The diagram can be hand drawn or computer drawn. Doesn't matter. As long as it includes labels. When deciding on where to pop in the diagram, put it near the method. However, this is where a lot of people mess up. People often think they can just draw a diagram and skip completely the method. No, the diagram is there to made the method clearer.
Also if you are using a lot of equipment, a diagram could be helpful on showing where each equipment is placed. But, like I said above, don't replace the words with pictures!
Tip 2: Present your knowledge
This is just a very simple Hypothesis which would at least give you a better grade than no explanation. The Hypothesis that I am wrting can take half a page. I am currently working on one so heres what I got:
"Hypothesis: We predict that the bottle filled with water would fall first. We
think that because according to what water and sand is made out of, water is
made out of Hydrogen and Oxygen. While sand is mainly made out of Silicon and
Oxygen. Silicon is a semi metal, which is heavier than the non-metals. Also,
sand is a solid material, water is liquid. We all know that a liquid is not
strong as sand, so therefore it would be lighter. However, a concept later
occurred in our heads. We think that the sand could have a higher centre of
gravity than water, due to the weight. So now we are a deadlock of which one
would fall first but the end we still decided that water would fall first."
That was only my first paragraph...Anyways, for MYP 1 and 2, I do recommend you start this practice. Although you won't get any marks for it, it is good practice so you don't panic when you come to MYP 3 (And believe me, teachers are very happy to see that)
Tip 1: Thinking the Beyond
Example:
Find how much Oxygen are there in a Magnesium Oxide.
So now you conducted an experiment, and got the results:
There is 0.012g of Oxygen inside a Magnesium oxide.
This immedietly brings you to 3-4 level.
However, to get a 5-6, you need to think beyond. In this case, you use Maths for this.
To do beyond of whats needed, you could just measure the percent. So after doing some simple (I think MYP 2 Maths level) calculations, you should come up with something like 0.5%-2%. Boom. That brings you to 5-6 immedetlly.
