On Friday 30th and Saturday 31st March, the Senior School Science Department organized and hosted its second Science Investigation Fair, and Excellence Exhibition. Grade levels across the Senior School division showcased their excellent work from IBDP Science Internal Investigations and Extended Essays in Grade 12 to multimedia projects in Grade 7.
We were especially excited to showcase the second SSIS Science Investigation Fair in Grade 8. For months, grade 8 students have been fine-tuning their research questions and developing their experimental method as they investigated a topic of their choice in more depth.
All participants planned their experiment, carried it out safely, analyzed their data, made appropriate conclusions and evaluated their investigations. This opportunity for students to choose the focus of their science investigation and take learning out of the classroom environment should help the students to make links between science and real world phenomena.
We were extremely excited to see our students display their Science Investigations and were astounded by the quality!
The Senior School students and science teachers will vote for the best investigations. The winners will be announced and bronze, silver and gold level prizes will be presented in a future Senior School Assembly.
Well done to all students that displayed their work at the Excellence Exhibition and especially to the grade 8 students that created outstanding Science Investigations.
We are already planning and looking forward to next years event.
The Double Helix Science Club is for young and inspiring scientists to explore science beyond our G7&8 science curriculum. It is for students that may have an interest in STEM (science, technology, engineering & mathematics) careers and for those that just what to do more hands on experiments.
The students will look at biology from the inside out by carrying out a frog dissection, make elephant toothpaste with chemistry and reach for the stars with bicarbonate rockets in physics.
When ASP Season 2 Mondays (different from day stated in video)
Max: 20 grade 7 &8 students
Plus 2 or 3 grade 9-11 Sciecne Club Assistants
Please contact Mr. Gaynor for more information
The Senior School Science Department extends a warm welcome to all returning and new students. We hope all students are well rested over the summer holiday and are excited about another inquisitive year learning Science.
We have been busy planning lessons, experiments, after school programmes and the Science Fair for the year ahead.
If you have any questions about this academic year please contact your child’s Science teacher or Mr. Gaynor: Head of the Senior School Science Department.
This week the grade 11 biologists made whiteboard summary flashcards on all subtopics studied this year. All the summaries were photographed and shared with the class. Students can review the pictures ona regular basis and test themselves on the content. This should help them prepare for the final end of year exams starting on Friday. SG
This year’s theme is Bad Science. To introduce this theme to the students the science department set up a number of stations highlighting everyday examples of Bad Science. Students moved station to station considering how each one was example of bad science and why many people believe it. The stations explored homeopathy, autism and vaccines, blood groups and personality, bad science in the media, climate change denial, everyday radiation levels, the science of successful names and the science behind food and health.
The students were engaged and asked a number of thoughtful questions. They are well prepared to choose their own bad science topic and investigate it in detail. They will have 10 hours to work collaboratively on their topic and present their findngs to rest of grade 11. This implementation and presentation part of the group 4 project is scheduled for 15th and 16th June.
To model the use of dichotomous keys to identify closely related organisms in Biology; lhe grade level students created a key to identify their shoes. They focused on the clear physical characteristics which could be used to separate the pile of shoes. Once the key was complete everyone was happy to get their shoes back! The students then created a key to identify some closely related insect species.
The grade 11 biologists followed up their research on the evidence for evolution by modelling Darwins theory of natural selection. They used different shaped tweezers, spatulas and test tube tongs to act as different beaks. They then competed for different food sources like rubber bands, paperclips, and rice grains the students understood the importance of variation in a population and how competition due to environmental selection pressure can lead to evolution.
This week in grade 11 biology we started to study topic 5: Evolution. We discussed the differences between facts and theories bringing in some thoughts from the Theory of knowledge coutse. We understood that theories are based on a vast amount of evidence and are our best scientific explanation for the real world phenomena we experience everyday. The students then researched the evidence from anatomy (homologous structures), paleontology (fossils), molecular biology (similarities between proteins and the universality of the genetic code), embryology and many other fields of biology. This topics recommended reading for students that want to learn more about the comprehensive evidence for evolution is Richard Dawkin’s The Greatest Show on Earth.
The grade 9 biologists have started studying the final grade 9 biology topic on ecosystems and human influences. To model the flow of energy through food chains we roleplayed the transfer of water (energy) from a large bowl (the sun) to a number of cups with holes in them (trophic levels) to find out how much water (energy) passed to the end of the chain. We then evaluated how the roleplay was similar to. energy loss (loss of water) through food chains and how it could be improved (including the role of decomposers). The students left the lesson with a better understanding of the fundamental concept of how not all energy is passed on to the next trophic level and hence why there is a limit to the maximum number of trophic levels in a food chain.
