An engaging resource for students to practice their understanding of the two pressure formulas: P=height x density x gravity and P= force/area. Students have to calculate the pressure that each animal/person is subjected to at different depths in sea water. They are given the lethal force required for each organism, using the P=f/a formula they have to work out if they survive or not. Extension activities could include - finding out the maximum depth they have to be at before they would die etc... You could ask the students to find a liquid that has a much lower density in which the organisms could survive greater depths. My students loved it and I hope your students do too. Enjoy!

Cambridge iGCSE Physics: SOUND AND WAVES Extension Exam Questions +MS. I have isolated some extension level questions from some extended papers (paper 3) for CIE iGCSE physics. This resource includes 3 whole questions (22 marks total) relating to sound waves and general properties of mechanical & EM waves. The mark scheme is attached within the PDF. The content belongs to CIE not me.

Second lesson on tropisms and plant growth (short lesson). Includes GCSE exam question as plenary. Progress check and very visual lesson.
