Room 9 are Scientists!

Room 9 were really lucky to be invited to spend a morning with 3 Otago University scientists last week. When we arrived, we had to get ready with our lab coats, gloves and safety glasses. Throughout the morning, we experimented with vaccines, extracted DNA from strawberries, looked at cells through microscopes, made lava lamps and made rain clouds in cups!

We had the best morning and learnt SO much about science! Otago University also put on the most amazing morning tea for us – we came back to school feeling very full and very excited to explore more science!IMG_7284Pumau looking at onion skin cells through the microscope

IMG_7267Donovan’s rain cloud – we made them with water, shaving cream and food colouring. We had to very carefully use a pipet to drop the colours, then watch them filter through the shaving cream cloud.

IMG_7257Dawn and Adele tested their ‘vaccines’. If the test tube liquid turned yellow (like Adele’s), that meant the vaccine had worked! If it turned red (like Dawn’s) it meant the vaccine was unsuccessful.


Lillian & Aiesha with their vaccines. Lillian’s successfully protected against the ‘virus’


Lukus & Rylee with their ‘vaccines’ – both vaccines worked!


AJ and Donovan mixing together the ‘vaccine’ – we had to measure very accurately using syringes.
