Word doc containing links to some excellent animations by DNA Interactive on YouTube. Also has descriptions of videos and transcripts.

Surface area to volume ratio explained. Simple worked mathematical examples given. Then calculations are completed. Finally, questions about biological examples show how knowledge of SA:Vol ratio are applied.

A very simple worksheet about kidney structure and function. Includes labelled diagram and missing words exercise. Ideal as an introduction, or perhaps a starter activity for a follow-up lesson.

Experiment to compare different sources of the enzyme catalase. Enzyme activity is measured and used to evaluate different sources of catalase. Knowledge of experimental procedures is reinforced, as well as use of correct vocabulary: independent/dependent/control variables, reliability, accuracy.

A template for carrying out pretty much any science experiment at KS3 and KS4. USe of correct terminolgy is reinforced. There is a section for describing results, and a separate section for explaining them. If used for every experiment, students will become comfortable with the procedure and be able to use the correct terminology in exams. And it’ll save ever having to produce another experimental worksheet ever again.

Physics - radiation. Data and questions from experiment investigating the effect of different colours of surface on heating and cooling. Questions on how long each surface takes to warm up from 24 to 30 degrees and how long they take to cool from 30 to 24. And the data gives the right answers!

Simple procedure to investigate how an abiotic factor (light intensity) affects biotic factors (% cover of two plant species). Pupils will already need to know how to use quadrats and how to estimate % cover. A 10m transect is measured out from a wooded area to an open area. Every metre, light intensity, % cover of grass and % cover of moss are recorded. All these can then be plotted on a line graph to show how they change along the transect. Conclusions can then be drawn about how light intensity affects each species. Also, the ideas of tolerance and competitiveness in plant species can be introduced.

Assessment for Learning. A sheet for students to complete after a test. They can use it to analyse their performance and drill into the mistakes they made in order to improve. There is a section to summarise the areas they need to improve and how they will do this.

Student sits with their back to the board. Key-words are displayed behind them. Rest of class have to describe the words to them in the style of Richard and Judy's famous game... Teacher moves onto next slide when guessed. Works best with smaller groups.

Two easy worksheets that can be filled in during an experiment with transformers.
