Gene Technology Access Centre (Gtac) Excursion Year 9 Extension Science Biology   

By Ling Sun and Alana Nguyen

Our Extension Science class travelled to the city with Ms Cassar and Ms Mair on the 15th of May 2015, to participate in a “DNA and Forensics” program at GTAC (Gene Technology Access Centre), University High School to complement our unit of work on genetics.

At GTAC, the MU (Melbourne University) science mentors and MU scientists organised a variety of “hands on” activities for us to apply our knowledge of inheritance, genetics, DNA and blood typing to real life scenarios.

We explored testing procedures and used advanced scientific equipment and materials such as blood reactants, metrical pipettes, an electrophoresis conduit box, UV light boxes to observe STR strands.

In one activity we acted as forensic scientists and applied our knowledge of genetics to solve a murder case. We examined trace evidence to determine if an unknown substance is blood; eliminated suspects; and prepared DNA profiles using gel electrophoresis.

Our MU science mentors showed us how to collect and test the synthetic blood samples, as well as how to read STR strands and hence, solve the murder mystery scenarios provided.

We learnt how to use the equipment correctly, as well as gain further knowledge about the double helix structure by constructing models of DNA molecules.

Overall, the GTAC experience gave us a valuable insight into a working laboratory, and allowed us to develop a greater knowledge of genetics and forensic testing procedures.

It was an enjoyable and memorable experience which has continued to spark our passion for science. 

Year 9 Advance – DUKES Adventurous Journey  

The Camp by Taneesha Tauali’i (9B)

On the 18th May, our Year 9 Advance class had a practice hike at Riddells Creek for their Duke of Edinburgh’s Award. On the camp, we had the tasks of putting our tents up in small groups, making our own food, putting our tents down the next morning and also supporting and encouraging each other during the ten kilometre hike.

What I learnt:

• Make sure that there were no sticks or rocks underneath the tent.
• It is better to start cooking early as it is difficult to clean in the dark.
• The hike was easier than I expected and it was great how different groups had a chance of leading and to show good teamwork.
• It was fun to play ambush and to stay outside at night.
• Put your backpacks inside the tent – it might rain.

I think it was an amazing time and experience spent with my friends and I really enjoyed it!

The Mt Charlie Hike by Jimmy Vo (9G)

First the hike wasn’t bad as we reached the resting points quickly, but as the hike continued, it started to get more tiring and difficult to finish. Although the hike was long and tiring, it gave me a chance to observe the fragile yet amazing bugs and beautiful plants. Towards the end of the hike, I spotted a kangaroo blending in with its surroundings and sadly, a dead snake. Taking off the backpack really made me feel like I was super light and I could jump really high as it took a big weight off my body. Hiking was much more fun than I expected it to be!

The hike met all my expectations - I was excited to be there and it was so amazing like “I couldn’t believe I survived that walk”! I can’t wait for the next hike at Lorne. We’d like to thank Ms Mortimer, Mr Micallef and Ms Borle for sharing this hike with us and having fun along the way!
