New resources for Biology exams in 2025
The InThinking Biology teachers site is about to get a new look ready fo the new Biology guide for first exams in 2025.
All the learning activities that you are used to using in lessons will remain, at least until November 2024.
This section will gradually fill with new resources, and some familiar resources remodelled and tailored for the new topics.
- Activities for students tailored to the topics of the new guide
- Tests for each topic
- Guidance about the IA
- Explanations and ideas for the Collaborative project.
- Revision resources for students
Creating new activities and incorporating all the new details into the topics does take time. We want to produce high quality resources that help teachers teach well and students to learn effectively within the IB pedagogical style.
Our original planning was a bit over ambitious so we have reconsidered the timescale and this is an updated plan.
Updated planning (Nov 2023)
- August 2023 Resease of Topic tests for all topics in Theme A & B and learning activities for A1.1,
- September / October 2023 Realease of Planning sheets and learning activities for A1.2, B1.1, B1.2, A2.1, A2.2, B2.1
- November 2023 Release of the Topics test for all topics in Themes C & D & Learning activities for B2.2, C1.1, C1.2,
- December 2023 Planned release of teaching resources for the Topics D2.1, D2.3
- January 2023 Topics A3.1 & A3.2 and the Navigation will be updated to give more prominance to the new topics
More new topics will be released through the winter of 2023 at a rate of 4 or 5 per month.
Completely new resources
Here are linke to Learning actvities which are completely new.
They illustrate the way we are crafting the new learning activities to embrace the new concepts that have been added to the Biology guide.
