Keep your budget and materials in mind.Many projects can be made simpler or more complex to fit your level. Don't discount an idea just because it doesn't seem to fit your educational level.A good rule of thumb is to choose an idea that takes less than half the total time you have. ![]() It's also possible that your experiment won't work out as planned, which would require you to develop an alternative project. Remember, it takes time to analyze data and prepare your report. Keep in mind how much time you have to complete the project, so don't select a science project that takes months to complete if you only have a few weeks.If you can, come up with five to 10 hypothesis statements and work with the one that makes the most sense. Write out your project idea in the form of a hypothesis as per the scientific method.It's interesting to see how a very slow event can spread news so quickly.Tips for Finding a Good Idea for Your Chemistry Project A similar experiment to the Queensland pitch drop was set up in Dublin, and the video of the moment the pitch actually dropped went viral on the internet. There's a live web stream that allows anyone to watch the glass funnel and wait for the fateful moment. The pitch drop experiment is something we can all participate in now. He held the job for 52 years, and missed seeing the drop fall three times – by a day in 1977, by just five minutes in 1988 and finally in 2000, when the webcam that was recording the experiment suffered a power outage for 20 minutes, during which time the pitch dropped. His replacement, Professor John Mainstone, became responsible for the pitch drop experiment from 1961. Professor Parnell died without seeing a pitch drop. The experiment has a tragic story associated with it. The last drop fell in April 2014 and the next one is expected to fall in the 2020s. Only nine drops have fallen from the funnel. Today it's been almost 90 years since the experiment started. It took another forty years for another five drops to fall. How slowly? Well, the first drop took eight years to fall. Since then, the pitch has slowly dropped out of the funnel. He then turned the funnel upside down and cut the top off it. He allowed the pitch to cool and settle – for three years. He heated it and poured it into a glass funnel. In 1927, Professor Parnell took a sample of pitch. At room temperature, pitch is many billions of times more viscous than water, but it's actually fluid. You see, when pitch is at room temperature, it feels solid. Parnell was the university's first physics professor, and he wanted to show in this experiment that everyday materials, such as pitch, can have quite surprising properties. It's called the 'pitch drop' experiment and it was created by Professor Thomas Parnell at the University of Queensland, Australia. This experiment began in 1927 and has been going ever since. In fact, it holds the Guinness World Record for being the longest-running experiment. In today's lecture we're going to be talking about experiments, and I thought it might be interesting for you all to learn about the world's oldest continuously running laboratory experiment that is still going today. ![]()
