Trish Tolan, a year one teacher
at Larmenier and Sacred Heart, and Sue Whear, a pharmacist from
Charing Cross Hospital, were successful in their bid for a £2,500
grant from the Royal Society to fund a science project. The project
on mixtures, suspensions and emulsions has been enhanced by the
council's Excellence in Cities team, who organise extra activities
for 'gifted and talented' children. During the first video conference Professor Hani Gabra brought together two experiments previously carried out in the class and conducted an experiment by sprinkling salt onto oil floating on water. The salt pushed the oil below the water only for it to float back up when the salt dissolved. At the second video session on Friday Professor Gabra expanded on a classroom experiment to show water will evaporate more quickly if heated. Salt that had been dissolved in the water crystallised out more quickly when heated than when left on the classroom desk. Year one teacher, Trish Tolan,
who is also the school's gifted and talented co-ordinator, said:
"We have been carrying out really exciting and practically-based
experiments with mixtures, suspensions and emulsions in class.
We related these to everyday life - the children have learned
that if you put washing up liquid into oil and water they will
mix because the washing up liquid is an emulsifying agent and
will remove grease from plates. The children have also made their
own emulsions of French dressing and butter, which they have enjoyed
eating! Last year Mrs Tolan and the children
in her class studied mould and bacteria in another project, also
in collaboration with Sue Whear, during which they visited Charing
Cross Hospital to see how pharmacists work in sterile conditions.
