Challenge Question pyramid based around the initial lessons for science for Year 7. Differentiated questions with easiest questions being worth 5 points and hardest question being worth 30 points. I usually set this as a challenge giving the students 20 mins to try and reach 100 points. Students highlight each question as they attempt them. This challenge can be approached in different ways from picking the easier questions and answering more questions or having less, but more challenging questions. It often surprises me as to how many students will challenge themselves to the harder questions and push themselves. Answers are included so students can self/peer assess. If you like this lesson, please leave a review and check out my other items.

This is the first lesson in the Edexcel Combined Biology Topic 8 on Exchange and Transport in Animals. This lesson covers Specification points 8.1, 8.2 and 8.3. There are practice questions and examples on SA:V calculations and a knowledge recall plenary with answers.

Differentiated questions for each lesson in the B7 Non-Communicable Diseases topic for AQA GCSE Biology and answers to go with them. These structure strips are designed to be printed off and glued into students books down the margin and then either used throughout the lesson, or as a task after covering theory, the students work their way through the questions. Not all students will be expected to complete the entire structure strip as it depends on target grades. The questions link directly to the learning objectives and ensure the content is covered and allows students to stretch themselves. They could also be given as homework for consolidation or used for targeted revision. Students find these a great way to ensure they have met their objectives and it makes marking books easier. The questions are split into three main groups: Bronze (Red) questions are targeted at Grade 4 Silver (Amber) questions are targeted at Grade 6 Gold (Green) questions are targeted at Grade 8 Star questions are challenge questions. Structure strips are included for the following lessons; Non-Communicable diseases Cancer Smoking and the risk of disease Diet, exercise and disease Alcohol and other carcinogens Answers are included as a powerpoint presentation for all structure strip questions to allow self or peer assessment by students. If you like this resource, please check out my other resources as I will be uploading more structure strips for both KS3 and KS4 topics and please leave a quick review for my resource. Thanks
