Activity for a Lesson on Metabolism (AQA 4.4.2.3)

Activity for a Lesson on Metabolism (AQA 4.4.2.3)

(6)
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

Organic Chemistry Functional Groups Guess Who?
Grefintec

Organic Chemistry Functional Groups Guess Who?

(1)
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?

Ladybird Counting Tins Numbers 0-5 (early numeracy resource)

Ladybird Counting Tins Numbers 0-5 (early numeracy resource)

(0)
I created these tins for use in my former nursery where they were enjoyed by children aged 2.5 years to school age. On one side are the ladybirds with 0 - 5 spots and on the reverse the number is written. The tins were left on one of the radiators and the children accessed them when they chose. Sometimes I would find some very curious things in the counting boxes but more often than not the quantity would match the number of spots on the ladybird.

The Twelve Days of Science (Festive Homework)

The Twelve Days of Science (Festive Homework)

(0)
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
