Technology and Practical: win-win situation

Technology and Practical: win-win situation

This term the Grade 11 Life Science students have been working very hard on their research and practical skills, in preparation for their Grade 12 portfolios. It is always good to take a break from formal, theory lessons!

Contraception and STD’s Talk

Contraception and STD’s Talk

The Grade 12 Life Science students had some fun learning about contraception and sexually transmitted diseases when we had Dr Hetta van Zyl (Obstetrician and Gynecologist) visiting the classroom as a guest speaker. Not only is this knowledge life long learning information but it forms a chunk of the IEB Grade 12 Life Science curriculum which will be examined in[Read More…]

Chicken wings please…

Chicken wings please…

Recently, the Grade 11 Life Science class dissected a chicken wing to investigate the similarities in the bones of the human arm and the chicken wing. They investigated the joint and structures like cartilage, tendons, ligaments and muscle tissue. After initial “oohs” and “ahhs” everybody did a fine job!

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…]

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!  

BIG concept… SMALL experiment

BIG concept… SMALL experiment

Photosynthesis: The life-saving process happening quietly and continuously around us daily. Grade 10 Life Science students performed various experiments to demonstrate the limiting factors of photosynthesis. Testing for starch is an essential investigation to determine if a plant photosynthesized, and all the students had the opportunity to perform the test by themselves.

Inside the KIDNEY with the Grade 11’s

Inside the KIDNEY with the Grade 11’s

The Grade 11 Life Science class was very excited to perform their first proper dissection. Hopefully, there will be a few future doctors judging by the surgical procedures observed! All the students found the experience intriguing and their interest and enthusiasm was evident.

Final Titrations in Physical Science

Final Titrations in Physical Science

        As the final countdown begins for the Grade 12 Physical Science group – we have to do a Chemistry practical as part of their year mark. Titration is a procedure where we neutralise an acid with a base and determining the exact volumes needed. Piece of cake!

Marvellous Molecules

Marvellous Molecules

The Grade 10 chemistry class this week got the chance to build and learn about the shapes of covalent molecules. The Grade 10s followed instructions to build linear, angular and tetrahedral molecules out of jellytots and toothpicks. Hopefully the knowledge will be stored by eating the molecules afterwards!
