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.

I spent one summer holiday doing these. I started with science specific words that I knew caused confusion. Then I continued with other words. I tend to use these to fill in five minutes during form time. e.g. Use each of these words correctly in a sentence. Students often like to come up with the silliest or the most original ideas for using each word.
Ecology sampling lesson includes exam style questions and answers.
Slide 2 is a learning framework
Slide 3 contains key words for the lesson LAPS use as a spelling sheet HAPS use as basis for a mindmap

Each worksheet results in the same answers (sheet supplied).
Gaps sheet is for the MAPS/HAPS as no missing words given.
Options sheet includes 2 alternative answers to choose from for most spaces so more suitable for LAPS

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.
