Determining Density

 Going through all the physics practicals as revision just before the exam. How many can be done in a session? All 4 in an hour running concurrently. Determining density was one of the quickest.

Low Power is best

Low-power microscopes scored much better than high-power microscopes for viewing all types of biological specimens. Sometimes, more magnification isn't better, especially for viewing insects and some pond organisms
 

A level computing 12 Mark questions

Practice planning the 12-mark A-level computing questions. It is not just about getting the facts down but also about organizing them effectively and using relevant examples.
 

Revision for Chemistry 1 done

 All the Chemistry Revision for Paper 1 is now done. All the required practicals have been gone over, and lots of past papers have been practised. Now, it's over to the students to show what they can do.

Momentum

 It's easy to understand how to stack the near-frictionless @pascoscientific trollies on top of one another to increase the mass two or three times and use the magnetic bumpers to create fully elastic collisions or the Velcro to create inelastic ones.

Tracing Paper

 Tracing paper, often overlooked, is one of the most vital tools for a math exam. Its versatility in helping visualize transformations, reflections, and rotations can significantly improve problem-solving efficiency. Remember to bring it! #MathExamEssentials

Water Turbine

 The water turbine shows a set of energy conversions that the students are quite familiar with. Gravitational potential energy is converted to Kinetic to Electrical in the generator and from there into light. I am not so sure about the Coloured Wheel, but it is interesting and gives rise to lots of interesting Physics discussions.
