Eukaryotic and Prokaryotic cells
Today in Biology, 9C1 had some hands-on fun creating Eukaryotic and Prokaryotic cells. Mr Rose provided the dough that the students were able to shape and design into the relevant cells . Later, they labelled the structure and transferred their knowledge into their exercise books.
Properties of Waves
Year 9 students were instructed by Mr McCarthy on how to carry out the GCSE required practical on observing the properties of waves in liquids and solids. They used a ripple tank for this practical, which projected onto a white board on the wall and so the students were able to measure the wavelength and the frequency of the water waves. The measurements were used to calculate the wave speed. Similar measurements were taken involving a stationary wave created with string.
Lavoisier's Law
Last Thursday Dr Lau introduced 9W1 to Lavoisier`s law of conservation of mass in chemical reactions. The students were set the challenging task of planning their experiment, demonstrating the understanding and importance of accurate measurements. They used balances to measure reactants to 2 decimal places and record their findings to prove that there was no change in mass after the chemical reaction took place. The results varied and the students acknowledged the conditions of the conservation of mass would need to be taking place in an enclosed system. They tackled this task superbly.
Year 8 Investigation
Luke in a Year 8 science lesson this week was using a microscope to investigate cells and took the following picture.
