My GCSE classes always like this. If you use good quality free range eggs they will last longer. The shells take longer to dissolve than cheap ones but the membranes are stronger so less likely to break. The syrup can be reused as often as needed for one set of eggs. It will get thinner but it still works. When the eggs are past their best dispose of them and the syrup as well. Each year when you teach this you will need a new set of eggs and a new jar of golden syrup.

I wrote this worksheet for a KS3 Chemistry lesson on particles. It is a standard dilutions practical. I wanted to see if my students could follow written instructions without any demonstration. We had done several lessons on particles, so they had enough science in order to be able to explain what was happening. You need a concentrated solution of potassium permanganate for this experiment rather than crystals. Explain what you are doing with it and your lab. tech. should be able to supply an appropriate quantity and concentration. The final dilution should be barely observable. Remember that each group only needs 1ml so the total amount for a class will only be in one small beaker. You need to do your own risk assessment but remember eye protection must be worn. Tip: you will find it easier to control if students use 1ml pipettes instead of the standard 3ml. Another tip: keep the concentrated solution with you at the front with one pipette. If each group sends a student to you with an empty test tube you can ensure that it is measured accurately. They then take theirs back to their bench and add 9ml water to it for their first dilution.

Activity to identify names of endocrine glands. Word doc. has 2 copies of slide 2 of the powerpoint. Makes for easier printing for A5 copies to stick in exercise books. Full instructions on slide 1.

Presentation to introduce abiotic factors Slides 1-9. Slide 10 has a video hyperlink to show woodlice in choice chambers. (Alternatively you could do this as apractical yourself.) Slide 11 shows the set up from the video and slide 12 gives the results from the video clip. Slides 11-12 are also supplied as a worksheet; 2 A5 copies on one A4 sheet. Students should calculate the mean for each condition from the results . Slide 13 works through the calculation answers then in the last slide 14 students have to decide which abiotic factor, light or moisture is most important to the woodlice. Written with AQA Trilogy in mind.

Pairs of science words that students might confuse, in meaning and/or spelling. Pick a specific slide to use in a lesson or pick one at random to fill a few spare minutes at the start or end of a lesson.
