New resources for Biology 2025 exams
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 (May 2024)
More new topics are regularly released, at a rate of approximately 4 per month.
These are the topics planned at the moment
- May 2024 - A3.2, B2.3, B3.1
Completely new resources
Here are links to Learning actvities on the site already which are completely new.
- A1.1 Water
- A1.2 Nucleic acids
- A2.1 Origins of cells HL
- A2.2 Cell structure
- A2.3 Viruses HL
- A3.1 Diversity of organisms
- B1.1 Carbohydrates and lipids
- B1.2 Proteins - Planning sheet
- B2.1 Membranes & transport
- B2.2 Organelles & compartmentalization
- C1.1 Enzymes & metabolism
- C1.2 Cell Respiration
- C2.1 Chemical signalling HL
- C2.2 Neural signalling
- D2.1 Cell and nuclear division
- D2.3 Water potential
They illustrate the way we are crafting the new learning activities to embrace the new concepts that have been added to the Biology guide.
Membrane lipids (2025)
Lipids are important components of biological membranes. The membrane lipids are amphipathic: part of the molecule is hydrophilic, and part of the molecule is hydrophobic. Membrane lipids may be classified...
Membrane Structure (2025)
An introduction to the components of the cell membrane begins this activity. This is followed by screencast of drawing a membrane diagram and a chance to practise drawing the structure. IB style questions...
Spontaneous origins of the first cells
This activity gets students to explore the evidence for the spontaneous origin of the first life on Earth and the research which has tried to identify the last unique common ancestor (LUCA) An information...
DNA for information storage (2025)
Storing the instructions to make an organism in every cell would be a huge waste of resources if the DNA molecule was not such a good information storage molecule. This activity takes a step back from...
Aquatic habitats (2025)
Students identify the important properties of water as a medium for life by comparing the adaptations of the black-throated loon and the ringed seal to life on land and in water, swimming and 'walking'....
The origins of water on Earth HL (2025)
Water is the medium in which enzyme reactions happen in all known living organisms. It is essential for life and many life forms use water as a habitat. We can see this in the oceans, lakes and rivers...
