#### Activity for a Lesson on Metabolism (AQA 4.4.2.3)

This is a Brainstorm detailing the key points of the AQA Biology 8461 syllabus. I have used it as part of a group brainstorming activity, as follows: Group pupils into teams with 4/5 members and ask them to work together to create a brainstorm on metabolism. To support them give them a copy of the 'cue sheet'. To ensure that all members have a role to play and take responsibility for it, also give the groups a 'group task sheet'. They have to sign their name against the role that they are going to take responsibility for. This ensures that everyone is taking part. Give them a set time to work on the task and then swap the brainstorms between groups and ask them to peer assess them eg write targets for improvement on post-it notes. Give them a set period of time to meet the targets. Then give them a printed copy of the already completed metabolism brainstorm. Ask them to make additions to their own and to highlight anything that they have got which is not on the prepared brainstorm Keywords: metabolism, enzyme, metabolic pathways, anabolic, catabolic, respiration, mitochondria

#### The Twelve Days of Science (Festive Homework)

Encourage independent learning with this 'Twelve Days of Christmas' template. Simply add text to the (bacteria/virus) baubles and ask your students to choose what they want to do. How you deliver this is entirely up to you. For example you could ask them to do a minimum of two home works. In order to position the text boxes over the baubles I have just used the number '1'. This means that they can be easily edited and personalised by you. #festive; #Christmas; #independent learning #homework

#### Negative Feedback: Control of blood sugar

#### Analogy: Effect of Non-Competitive and Competitive Inhibitors on the Rate of Reaction

Analogy for Competitive and Non- Competitive Enzyme Inhibition Rate Graph Situation: Preschool birthday party game 'musical chair's'. The preschoolers are the substrate, the chairs are the enzymes. Competitive Inhibition Some of the parent's want to play. But the more preschoolers there are the less likely the dads are going to get a seat when the music stops. Eventually there will be a point when they are out competed for the seats because there are so many preschoolers Non Competitive Inhibition The preschoolers have older siblings who are too cool to be at a party like this. When the music starts they run around pushing the chairs over so they can't be used in the game anymore. It doesn't matter how many preschoolers there are they can't ever fill all of the chairs because some are out of action.

#### AfL: What I knew then...What I know now - A simple way to demonstrate progress.

Formative Assessment/Assessment for Learning 1. At the start of a new topic, get your pupils to stick this in on the first page. 2. Ask them to write everything that they already know about the topic in the centre square. 3. Then either mid way through the lesson, or mid way through the topic, turn back to this first page and ask the pupils to write everything that they know in the middle rectangle - using a different colour ink really highlights their new learning. Also at this point they can work as a 'talking pair' and expand on this. 4. At the end of the topic, return to this first page and complete the final rectangle, again using a different colour is a good idea, as is incorporating 'talking pair' information. A simple way to let both you and your students know what progress they have made.

The challenge levels are indicated by spiciness, the spicier the task, the more challenging it is. Keywords: whole school, homework, task sheet, worksheet, class template, chili, differentiated

#### Organic Chemistry Functional Groups Guess Who?

A Guess Who game designed for pupils revising Organic Chemistry functional groups. Inspired by the childhood game 'Guess Who?' and played in a similar way. Print out pages two copies of page 1 and print on the reverse page 2 so that when folded in half (as in the picture) the title page obscures the view of the functional groups. Print out two copies of page 3 and cut out the rectangles. Players face each other. Each player chooses a functional group and keeps it a secret. Players take it in turns to guess the identity of the other player's chosen group using clues associated with the different groups. Players use the white rectangles to cover the functional groups eliminated from the game. First player to guess the other player's functional group wins! Keywords: organic chemistry, functional groups, alkanes, alkenes, alcohols, aldehydes, ketones, carboxylic acids, esters, halogenalkanes, game. Guess Who?
