Prof. Florence Wambugu, a renowned agricultural biotechnologist and the founder of Africa Harvest Biotech Foundation International, is currently entangled in a row with the South African government over her plan to set up a multimillion dollar research laboratory and greenhouses to develop genetically modified sorghum. Prof. Wambugu has received a huge grant - US$415 million - from Bill and Melinda Gates Foundation, to develop genetically modified crops, which have proved essential in alleviating food insecurity. Her choice of South Africa stems from the fact that it’s the only African country with Biosafety laws. South Africa’s early enactment of biosafety laws has made it the preferred destination for biotechnology investors. To now hear a country that’s gained international reputation for its friendly policies towards biotechnology is attempting to block an African scientist from advancing a biotechnology cause is appalling. In justifying its decision to suspend Prof. Wambugu’s project, South Africa’s agricultural regulatory agencies have claimed that the genetically modified sorghum can contaminate varieties native to Africa. This looks like a pedestrian argument and it’s tantamount to putting the cart before the horse. For the record, Prof. Wambugu has not yet shipped genetically modified sorghum to Africa. All what she wants to do is to set up a laboratory to conduct research on the same. All what Prof. Wambugu currently wants is to build the infrastructure for genetically modified sorghum research. Such can in no way interfere with the so called indigenous African sorghum varieties. Prof. Wambugu will, at one stage, conduct field trials of her genetically modified sorghum. Then is the right time for the South African government to be worried about “contamination.” It should not be lost on anyone that South Africa has well-entrenched genetically modified organisms (Gmos) regulatory laws. So, it’s unlikely that the new genetically modified sorghum will be developed outside such laws. Genetically modified crops are not alien to South Africa. It’s not the first time a new genetically modified crop is being introduced into South Africa. The laws that governed the introduction of genetically modified corn and cotton, currently being commercially grown in South Africa must be applied to Prof. Wambugu’s genetically modified sorghum. The Bill and Melinda Gates Foundation, by investing in agricultural biotechnology research, is sending a stark message to African countries that it’s committed to finding a permanent solution to Africa’s chronic food problems. The best way to reciprocate this generous gesture is for African governments to allow scientists like Prof. Wambugu to do their work unimpeded.

Understanding the scientific method and how to follow it is critical to building a good reputation in the technical community. In regards to science fairs, as a student progresses in grade levels the judges are going to demand more and more focus on using the scientific method. Here is my seven step description of the scientific method. 1. Define the question 2. Gather information and resources 3. Form hypothesis 4. Perform experiment and collect data 5. Analyze data 6. Interpret data and draw conclusions that serve as a starting point for new hypotheses 7. Publish results In science fair competitions, if you can show that you are following the scientific method, you are well on your way to impressing the judges. Basically, start out by defining your question and topic. After that, form a hypothesis and perform your experiments. Step 6 is where you use that data to make any new hypotheses or theories about your science topic. If you want, you can take that new hypothesis you just developed and start again from step 3, then move your way back to 6. Follow this cycle as much as you want. The more focused your information and experiments the better. Would you like an example to clarify how to use the scientific method? Imagine you are doing your project on "Hot water" and we are going to follow the scientific method steps. 1. Define your question. How about something silly, like "Will boiling water burn a person's hand?" 2. Find lots of information about hot water and learn everything you can about it. 3. Now form a hypothesis based on your research. Our hypothesis is, "A person will not suffer any burns due to contact with boiling water." Hopefully you are smart enough to know this isn't true, but let's pretend we aren't just for the sake of the example. 4. Now we do perform our experiements. In real life we know we will burn ourselves with boiling water, and we should never touch it! But, suppose the experimenter has no idea. They run tests to see if contact with boiling water burns a person. BAD IDEA! 5. Now look at your data. Probably everyone in the experiments burned their skin during the tests. Looks like boiling water does cause burns! DUH! 6. Interpret the data. Hmm...our hypothesis was completely wrong. Our experiments showed that boiling water can cause burns. 7. Publish your results. I certainly hope you never make a project just like this, but here's your chance to show the world what happens when you touch boiling water! Keep in mind, don't change your hypothesis because your final data did not agree with it. You don't get more credit for having a correct hypothesis. You get credit for following the scientific method and coming to a correct conclusion based on your data. Don't forget to include possible reasons for experimental error. If you follow these steps your project or experiment will make sense to anyone who views it and you have a good chance of succeeding!
