Electricity and all that jazz in Grade 10

Electricity and all that jazz in Grade 10

In Grade 10, the Physical Science students start to build series and parallel circuits to calculate the total resistance in the circuit. What always amazes me, is how much more the boys know about this topic than the girls, especially when it comes to the building and applications in everyday life. To all the mothers of little girls: A note[Read More…]

SHOCKING Creations in Grade 8!

Grade 8’s were put through the fire on Monday when they had to bring all their equipment to make their first electric circuit. They had an hour and a half to build a basic circuit containing a switch, power source, conducting wires and a resistor of their choice to show that the circuit was closed eg. a light bulb. This[Read More…]

EXAM FEVER

EXAM FEVER

We are approaching exam time and that always means two things.. Many stressed students and lots of marking for the teachers. I cannot help but think about the amusing, and sometimes very smart answers popping up while marking exam papers. A fellow teacher once had the question: “What is a Nazi?” in a history exam. the local afrikaans boy answered:[Read More…]

Physical Science Grade 11: Fast, Faster, Fastest!

Physical Science Grade 11: Fast, Faster, Fastest!

The Grade 11 Physical Science students planned and performed rates of reaction experiments where they investigated how the speed of Hydrochloric acid reacting with Magnesium changes when the concentration changes. Each student had to research a different method and then perform and record it by themselves. Science is so much more fun when we learn by means of practicals!  

Electricity in the air for Physical Sciences Grade 10

Electricity in the air for Physical Sciences Grade 10

Sparks have been flying in the Grade 10 Physical Sciences class this term as we’ve been investigating the static electricity hiding in objects around us. We have seen that even a neutral object can be charged for a while if you put enough effort into it. When rubbing a ruler with a cloth, electrons are transferred from one object to[Read More…]

The shapes of molecules in Physical Sciences

The shapes of molecules in Physical Sciences

In Grade 10 and Grade 11 Physical Sciences we are learning about chemical bonds. To better understand what happens between the different particles or molecules bonded together, it helps to know what the shapes of these molecules are. What the molecules look like. These shapes can be quite complicated and difficult to visualize three-dimensionally. A hands-on approach often helps students[Read More…]

Natural Science: Groundbreaking or Beer-making?

Our Grade 8’s had a chance to test out their science skills in their first ever, proper, high school science experiment! It had some exciting results. Not least of which was one experiment exploding in the fridge…rather a smelly mess! The Grade 8s were given instructions to go about proving an hypothesis and recording their results. The hypothesis was that that[Read More…]

Different states in Grade 10 Physical Sciences: it all matters!

Different states in Grade 10 Physical Sciences: it all matters!

Physical Sciences is the study of non-living natural objects. Basically, investigating everything around you, and figuring out how it works. Before you can study the function of something, you need to understand what it is made of. That is where “matter” comes in, and specifically the different states of matter. Everything consists of matter. Small particles either closely packed together, or[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…]

Investigating Chemical Reactions in Physical Science

Investigating Chemical Reactions in Physical Science

There is always time for an experiment in the Physical Sciences class! Even though it was almost the end of the term and exams were upon us, the Grade 10 and 11 students grabbed lab coats and investigated chemical reactions. The Grade 10 students were given three unknown solutions, all containing potassium salts. Each group had to identify their solution by[Read More…]
