Simple Power Point which could be used as a plenary after completing food tests or as a starter before students carry out food tests on different foods.

Simple activity where students have to use the clues in the text to construct a food web. They then use their food web to answer questions. Learning objectives provided on a ppt. Students will have had to do some work on food chains and food webs and key terms previously. They will need a chunky pen to draw food web arrows and a large piece of paper to stick pictures onto. I usually hand these out already cut up in envelopes. You could laminate them and give the students blue tack to hold them in place.

Research project where students learn by carrying out an inquiry as to whether they could live on their favorite food alone. Requires them to copy out a food pyramid, find out about different sources of nutrients and investigate deficiencies. Access to computers and reference books required.

A fun way of getting pupils to look at graphs in Science. Could be used as a starter or pleanary. Print the interpreting graphs activity out and laminate to make four different colour, double sided cards. Organise pupils into groups of two or three and provide each group with a set of four cards. Introduce the activity using the first page of the Power Point. Pupils use the clues on the back of the cards to help them describe what is happening in each graph, answers can then be shared as a class using the Power Point.

Students have to choose a drug to research - some focus questions are provided. They then have to use the information they have found out about the effects of their drug to write a 'lab rat diary'. Imagining they are a scientist administering the drug to a rat, they have to make a note of what they would observe. The lab rat is from the Cannon website. This activity will take about 3-4 lessons, plus homework. Access to a computer room and library a must.
