Should we change anything?

Hi!
- Experiment: Most effective natural fly repellent.
We could split up into three groups of 2 each to do one investigation / experiment... What do you think?

Hey!
We found out today that we cannot get citronella oil or eukalyptus oil... I suggest using garlic instead... it's supposed to keep flies away, too.
I changed the method to suit the flies we bought and it now includes only four repellents:
Method
1. The six jars will be clearly labelled in the following manner:
Control
Lavender
Garlic
Peppermint
Basil
2. Two table spoons of honey will be put into each jar.
3. 10g of lavender will be crushed and put around the opening of the jar labelled “Lavender”
4. 10g of garlic will be crushed and put around the opening of the jar labelled “Garlic”
5. 10g of peppermint will be crushed and put around the opening of the jar labelled “Peppermint”
6. 10g of basil will be crushed and put around the opening of the jar labelled “Basil”
7. The bell jars will be placed next to each other under same light, noise and air conditions.
8. One jar containing honey, 5 house flies and 10 fruit flies will be put under each bell jar.
9. The jars will be left for 15 minutes.
10. The flies stuck in the honey for each experiment will be counted and their number will be noted down.
11. The jars will be left for another 15 minutes.
12. After precisely 15 minutes, the flies stuck in the honey for each experiment will be counted.
13. The results will be noted down.
14. The jars will be cleaned.
15. Steps 2 to 15 will be repeated 2 more times (in total there will be three repeats for each experiment).
16. The apparatus will be put away.
17. The results will be compared, analysed and interpreted.
Is that okay? Using different flies will also show how different species react...

xx, Amelie ------Hello Guys! I think the method is very good!, Thanks Amelie.So, would it be 5 drops of natural oil repellent for each experiment??I think we will need a greater amount of the natural repellents to make it work properly, without diluting it in water.I am a bit confused with the step 9. Where are the flies going to be in the first place? The flies need to be far from the honey. So it has to be placed first the honey, then the repellent and then the flies to see if the flies dare to go to the honey with the repellent. Mariana

Hi!
I just read that we have to carry out at least three experiments or investigations...
As we focussed on flies so far, I recommend sticking to that...
How about following investigations/experiments:
- Investigation 1: The effects of flies on health and hygiene (how they transmit diseases) - this knowledge will help prevent diseases etc.
- Investigation 2: How flies live (climate, reproduction...) and what they are attracted to - this knowledge will help avoid them.
- Experiment: Most effective natural fly repellent.

I just wrote the following email to Mrs Marchetti:
Dear Mrs Marchetti,
We found a place where we can buy living house flies, so we are going to investigate those instead of moquitoes. They also transmit diseases such as cholera and are a hazard to hygiene. Is it okay if we buy the flies ourselves?
Apart from flies we also need:
- 6 bell jars
- 6 smaller jars with a small opening
- honey
- basil (about 16 leaves)
- lavender
- citronella oil (20 drops)
- eucalyptus oil (20 drops)
- peppermint (about 16 leaves)
If we need to buy those things ourselves, please let me know.
Regards,
Amelie
okay? Let's go ahead and write the method...

Is that okay?

I found on the internet about natural repellents for flies http://www.flyrepellent.org/
Basil is a natural fly repellent. Placing a pot of sweet basil near your kitchen window and doorway will help to repel those flies away.
act as fly
fly repellent in
in your garden.
What do you think?
We need three more we could use.
We can have 5 bell jars, you are right! 21 jars is crazy. We can use one jar four times for the same experiment.

Hey!
I found some more natural fly repellents:
Lavender oil - lavender is considered to be particularly effective against flies[1]
Citronella oil (dilute with water first)[2]
Eucalyptus oil (dilute with water first)[3]
Pennyroyal oil (dilute with water first)[4]
Peppermint oil (dilute with water first; likely more effective against mosquitoes but also considered to work against horse-flies[5])
Lemongrass oil (dilute with water first)[6]
http://www.wikihow.com/Make-Natural-Outdoor-Fly-Repellent-with-Essential-Oils
I suggest using basil, lavender, citronella oil, eucalyptus oil and peppermint. This way we have a mixture of plants and oils...
Is that okay?

Hello Amelie!
I agree with you. I think is better if we investigate the different natural fly repelletnts.
I will go with you to buy the flies on monday.
I found on the internet about natural repellents for flies http://www.flyrepellent.org/
Basil is a natural fly repellent. Placing a pot of sweet basil near your kitchen window and doorway will help to repel those flies away.
As an alternative, you can also place pots of Lavender around your home. Lavenders are both beautiful and nice smelling plants that can act as fly repellent in your garden.

Thanks for sending the mail!
As Mrs Marchetti said they couldn't get any mosquitoes, why don't we work with house flies? They also carry diseases and are a hazard for hygiene. I did some research and found a place where they sell living house flies:
Reptilien-Center
Industrie Gaswerk Nord
Kohlestrasse 10
Schlieren
http://shop.reptilien-zoo.ch/000001985b0e5e29a/000001985b0d72576/27318799e20fec467.php
http://www.reptilien-zoo.ch/default.asp?id=11&ACT=5&content=14&mnu=11
I would be willing to go there Monday after school to buy the flies.
However, we need to redo our research and find natural repellents for house flies instead...
I don't think we need such large quantities, but other than that I agree with your e-mail. I think we should do the repeats after each other... then we only need 5 bell jars, 5 jars...
What do you think?
Amelie
