Experiment Suggestions

OK. So I’ve finally figured out the basics of “blogging” and in the process have accidentally followed myself. = =’
Anyways, I found a helpful website: http://www.easy-kids-science-experiments.com/high-school-science-fair-topics.html

I found three different experiments that seem interesting:

(Briefly describing)

Testing Permanent Markers
Experiment: How permanent are permanent markers?
Materials needed:
- Black permanent marker
- Water
- Rubbing alcohol
- Vinegar
- Soft drink (coca-cola)
- Materials to write on: Plastic, Paper, Cotton
- 4 eye droppers

Method: A thick black line was drawn across each piece of material (plastic, paper and cotton) and was left to dry for 20mins. Each piece of fabric was then cut into four equal pieces. Three drops of each liquid (water, rubbing alcohol, vinegar and coca-cola) was instilled on each piece of fabric and left for 15 minutes. Observations were made and results recorded. This experiment was repeated 3 times.

What Materials Work Best in a Sandbag for Preventing a Flood?
Experiment: What Materials Work Best in a Sandbag for Preventing a Flood?
Materials needed:
- Sandbags
- 4 aluminium containers
- Sand
- Woodchips
- Soil
- Coarse Gravel
- Stopwatch
- Water
- Bucket
- Measuring cup

Method: A third of the aluminium container is sawed off. Sand is poured into the sandbag and placed in the aluminium container. 500ml of water is measured with a measuring cup and poured into the aluminium container. A bucket is placed underneath the aluminium container. After 5 minutes the bucket is removed and the water in it is measured. Observations and results were recorded. This experiment was repeated with the other three materials: woodchips, soil and coarse gravel. This experiment was repeated 4 times in total.

Which brand of paracetamol is the most effective?
Experiment: Which brand of paracetamol is the most effective?
Materials needed:
- 5 different brands of paracetamol (panadol, nurofen, panamax, advil and herron)
- Water
- Thermometer
- Stopwatch
- 5 glass cups
- Measuring cup

Method: 100ml of water (at normal human temperature, approximately 37 degrees) was placed into 5 glass cups, the temperatures were recorded. One tablet from each brand of paracetamol (panadol, nurofen, panamax, advil, and herron) was placed in the cups until the paracetamol had dissolved. The time it took to dissolve was recorded with the stopwatch. The experiment was repeated 3-4 times.

OK. So I have three choices now so that’s cool. Miss Zhang, could you give me your opinion on which experiment would be most suitable. If you can that is, it’s not cheating is it? >.>

If none of them are suitable because it's too simple or not year 10 standards I'll find something else on the net.
Once I’ve figured out which experiment I’m doing I’ll post up the background info and stuff etc.

I’m outta here.
