Science - Crest Investigations

The last few days of Crest have arrived! Everyone is stressing, trying to get everything on their presentation boards. There is a lot of buzz, excitement, many sighs of relief and a proud feeling of achievement.

In Year 7 Science everyone has to do a Crest Project over 7 weeks of Term 2. Our success criteria has been:

♦ Ask a testable question

♦ Research the topic

♦ Make a hypothesis about the outcome based on the research or their

own knowledge

♦ Design the investigation

♦ Conduct the investigation – hands on experiment

♦ Collect Data

♦ Make sense of the data and write a conclusion

♦ Present your findings to be judged

An example of a testable question is, ‘Which brand of dishwashing liquid makes the biggest yeast reaction?’

At Selwyn House Crest is very important and it builds up our skills for Year 8, which is the year that we have to do personal projects.

Airport Visit

Sniff, Sniff, I smell kiwifruit! Time for my next treat!!

Our new inquiry is about Biosecurity. 'Biosecurity' is the protection of New Zealand's economy, environment and people's health and social and cultural wellbeing from pests and diseases. It includes trying to prevent new pests and diseases arriving, and eradicating or controlling those already present.

Yesterday we went to the airport to learn more about biosecurity. It was great to have a chance to watch the dogs smell and what their reaction is when finding a forbidden plant or food. We also learnt what type of things people bring in. Someone even tried to smuggle leaves in their underpants!!

Zane, the dog that smelt the fruit and vegetables in our pockets, was very enthusiastic for a treat. Wendy, the dog handler, hid some fruit and vegetables, including beef jerky, egg, kiwifruit, spring onion and garlic in our pockets and Zane had to find them. Zane was amazing he found everything and he even found a mandarin in Miss Glubb’s handbag! Every time that Zane found an item he would be stare adorably at Wendy for a treat.

Zane is a beagle who began this role when he was 2 years old. He is intelligent and his nose was really working overtime!!!! These dogs normally work for 7 – 9 years as long as their enthusiasm remains.
