Year 6: GDST Science Conference
On the 4th of March, five girls attended the GDST Science Conference at the Royal Institution. Nuriyah, Violet, Isabelle, Nina and Diamante, along with two excellent members of staff, experienced an astounding day with crashing cars, science talks and extracting our own DNA.
After a warm welcome by the Royal Institution staff and some refreshments, we headed to the first activity. We were asked to build and adapt a paper car to survive a crash test with a very special passenger inside. We created unusual ways to protect the car from being damaged and learnt all about the crumple zone. Once our cars were ready, we found out that our special passenger was in fact a pringle! After a very successful crash we observed the other groups’ crash tests. In the end our car had won and our pringle had survived.
Next, we were led to the theatre to listen to two extraordinary scientists. The first studied lakes and zooplankton, which are a very small, see through creatures. She talked about the fact that even though they are so small they are essential for life to thrive in the lake she studies. The second scientist studied cancer. She was coming up with a way to treat cancer by using photodynamic therapy to get rid of cancer cells in the body. They then answered many of our questions.
After lunch, we went on a very short self-guided tour of the Royal Institution, followed by our next activity. The third – which was by far our favourite activity – was extracting our DNA to put in a bottle. We all wore our goggles, gloves and lab coats to keep us safe from the chemicals we would be using. We massaged our cheeks for one minute and then drank some water and spat it back into the cup so that in our cup there were some cheek cells. With a pipette we put in 3ml of the water into a test tube and then some detergent. With a micropipette one of the members of staff there put 30 microliters of protease into the test tube. They then put the tubes into a hot bath at 50° for seven minutes. We were told that this was so that the protease had time to react. Seven minutes later, we put in some ethanol and then transferred it into a small vial and attached a cord to it and there we had our DNA in a necklace.
Immediately after, we all gathered inside the large theatre again where we watched a science show featuring the staff at the RI. The show was called The Messy Science Show. There was a tombola drum with inside plastic spheres with pieces of paper inside detailing what kind of mess it should be, such as a cold mess or a wet mess or a loud mess. Volunteers were then picked from the audience to spin the tombola drum and pick a mess. Two volunteers were selected from Sutton High School. The first was Nuriyah. She chose a plastic ball with inside a dangerous mess. The second was – when another girl chose a mess that could go wrong – one of the teachers who accompanied us (Ms Marange) was selected from the audience to sit on a stool with a poncho and have goo accidentally poured down it.
After a laugh filled day, we were at last ready to head back to school. On our way out we each received a GDST chocolate bar.
In conclusion, it was a wonderful experience and one we won’t forget. We hope that next year sixes will have as much fun as we did.
