This week we had a wonderful opportunity at St Emilie’s. Sandra Lavery (Jack Tarandetti’s auntie) came to St Emilie’s to present chemistry workshops to the students in Years 3, 5 and 6. Sandra is a chemistry teacher at Lynwood Senior High School and she was keen to share her passionate about chemistry with he St Emilie’s students.
The students enjoyed several experiments. Here are some photos to show the experiences offered to students on Thursday.
The students got to shake this bottle and see the colour change from blue to ‘colourless’. Mrs Cogger learned something new. In chemistry liquids are never called ‘clear’. The correct term is ‘colourless’.
Sandra brought along a transportable bunsen burner. The Year 6 students can look forward to using bunsen burners at high school next year.
Jack T was Sandra’s lab technician for the sessions. He did a great job. he especially enjoyed helping out with the investigation involving a ‘flame’.
Sandra demonstrated that by heating a particular chemical in its liquid form it could be changed to a solid.
Sandra added zinc to a conical flask and another chemical and we watched it bubble. Then she placed a balloon tightly over the opening of the conical flask and trapped that was being produced.
Sandra showed us the magic of ‘elephants toothpaste’. One of the ingredients is hydrogen peroxide.
We recorded our observations and learning throughout the workshop.
Sandra used a string to ‘slice’ through an ice cube. Then she demonstrated the three states of matter by melting the ice cube and allowing the water vapour to inflate the balloon.
One of the students favourite investigations was when the egg was ‘sucked’ into the conical flask.
Sandra set up all her chemistry equipment and show the students how to create carbon dioxide. She ‘trapped’ the gas and used it to put out burning tea light candles.
To finish off her chemistry extravaganza show Sandra seta taper candle flame to a balloon filled with hydrogen gas. And the students were delighted to see the balloon explode!
Mrs Cogger interviewed some of the students on Friday morning and prepared this short iMovie about our chemistry with Sandra. Please click the link below to view the imovie.
Mrs Cogger and the students would like to thank Sandra for providing this wonderful opportunity for the students.
