This is the video to go with an ASAB (Association for the Study of Animal Behaviour) teaching resource for AS/A2/Higher/Advanced Higher Biology and Psychology.
The resource has three main elements:
(i) Teachers’ notes with general background information on leaf-cutting ants and suggested answers for all the tasks.
(ii) An investigation into the foraging preferences of leaf-cutting ants. This task is designed for students to collect data by observing DVD film footage of the ants’ behaviour. Students will need to analyse the data using the chi-square test and interpret the outcome in relation to their test statistic. This task also includes ‘How Science Works’ and application of knowledge questions for students to consider aspects of the experimental design and behaviour of leaf-cutting ants.
(iii) Extension activities focusing on two other statistical analyses.
1. ‘Are females better parents than males?’ Students will need to apply the standard error and 95% confidence limits to data collected in an investigation into the parental behaviour of male and female burying beetles.
2. ‘Is there a relationship between the forewing lengths of moths?’ Students will need to apply the Spearman rank correlation test to data collected about the left and right forewing lengths in large yellow underwing moths.
The teacher notes will be sent out FREE as a pdf. To request the notes to go with this video simply send an e-mail to the ASAB Education Officer - email@example.com. This resource was written by Richard Bottrill (Head of Biology at Wilmslow High School, Cheshire).
