All about breathing – Life Sciences grade 10 and 11

All about breathing – Life Sciences grade 10 and 11

In the Life Sciences class, the grade 10 and 11 students have been investigating different aspects of breathing by doing various fun activities. First we looked at everyone’s tidal volume. This is the amount of air that a person can store in their lungs to use for breathing. In the experiment, each student tried to displace as much water from a[Read More…]

Investigating photosynthesis in Life Sciences Grade 10

Investigating photosynthesis in Life Sciences Grade 10

After studying the process of photosynthesis intensely, the Grade 10 Life Sciences class did a practical investigation on the effect that different environmental factors have on the process of photosynthesis of a plant. Different plants were first placed into different environments and left over the weekend. Two plants with different types of leaves were put in a dark box, therefore no radiant[Read More…]

Seen AND heard in Grade 11 Life Sciences

Seen AND heard in Grade 11 Life Sciences

We have been studying two receptors in Grade 11 Life Sciences: the eye and the ear. These receptors convey information regarding the environment to the brain. This section forms part of the Human Nervous System. Zeze, Kirsten and Paige In the nervous system, receptors activate our response to external or internal stimuli from the environment. When these receptors are activated, nerve impulses travel through[Read More…]

Putting life into Life Sciences at Silvermine Academy

Putting life into Life Sciences at Silvermine Academy

We have been investigating many aspects of life in the Life Sciences classes at Silvermine Academy. After learning about different hormones and the glands that secrete them, the Grade 12’s have zoomed in on the molecule that determines what you look like: DNA or Deoxyribonucleic acid. This fascinating molecule does not only carry all your genetic material, it also controls[Read More…]

Mastering METHODS and SKILLS at SMA

Mastering METHODS and SKILLS at SMA

The budding scientists at Silvermine Academy have started the year with their usual enthusiasm. We are focusing on the Scientific method in Life Sciences, and refining our Scientific skills in Physical Sciences. In scientific investigations, planning is just as important as your results and conclusion. As Tim Minchin said, “Science is simply the word we use to describe a method of organising our[Read More…]

SMA Life Sciences: at the Heart of it all

SMA Life Sciences: at the Heart of it all

While the Grade 12 students are working hard on their preparation for the final exam, the Grade 10 and Grade 11 Life Science students have taken over the laboratory for their own investigations. An exciting part of the Grade 10 syllabus is studying the circulatory system, in which the heart is a major organ that controls the cycle. The Grade[Read More…]

Grade 10 Liver Dissection

Grade 10 Liver Dissection

The Grade 10 Life Science students did a practical dissection task with liver this week. The aim of the experiment was to investigate the efficiency of catalase in various conditions. Chicken liver was used during the experiment and the whole class was very excited. One of the students was particularly excited and took the lead with getting the investigation underway.[Read More…]

Repro!? DUCTION!

Repro!? DUCTION!

Last term the Grade 12 Life Science class went to a Human Reproduction Workshop at Elkanah House. The head of Life Science at Elkanah, Mr Pete Le Roux, offered valuable insight on the topic. It was an informative and interesting talk. The matrics were focused throughout and learned so much. This workshop has given all of us a brand new[Read More…]

The Power of Poison

The Power of Poison

Last week the Grade 11 Life Science and Physical Science students went to The Power of Poison exhibition at the Waterfront in Cape Town. This exhibition included everything from tiny frogs, to explanations of the intensities and sources of the strongest poisons, to explaining how poison has played an inseparable part in fairy tales and novels. There were even opportunities[Read More…]

Work = Applied Force x Displacement

Work = Applied Force x Displacement

As we are heading towards the end of the term with great velocity, we have covered quite a bit of distance. This distance was not directionless though, but was only heading forward, thus termed displacement. We admit that there has been some friction along the road, but we are positive that putting enough energy into the system will maintain the[Read More…]
