Deep Dive in IBDP Biology: C.2.2 Neural Signalling Teacher Resource Pack

IBDP Biology Resources for C.2.2 Neural Signalling

In the fascinating world of neural signalling, IBDP Biology students dive into the electrical and chemical processes that allow neurons to communicate. From action potentials and synaptic transmission to the effects of neurotransmitters and the complexity of consciousness, Topic C.2.2 offers a deep exploration of how the nervous system powers thoughts, emotions, and movement.

To make this intricate topic accessible and engaging, we've designed a comprehensive C.2.2 Neural Signalling Resource Bundle that empowers educators with ready-to-use activities, visual tools, assessments, and lab-based inquiry. This bundle aligns with the IBDP Biology curriculum and supports multimodal learning across all student levels.

🧠 Section 1: Launch & Reflect – Bell Ringers and Exit Tickets

✏️ Neural Signalling Bell Ringers

Jumpstart lessons with these thought-provoking prompts covering:

• Neuron anatomy and the generation of resting potential (C.2.2.1–2)

• Propagation of action potentials and saltatory conduction (C.2.2.3–4, C.2.2.11)

• Synapses and neurotransmitter release (C.2.2.5–6)

• Depolarization and repolarization (C.2.2.8)

• Summation, pain perception, and consciousness (C.2.2.14–16)

These questions encourage critical thinking and retrieval practice while aligning closely with command terms and curriculum language.

✅ Neural Signalling Exit Tickets

Wrap up your lessons with short-form reflections that reinforce key content. These include:

• Describing differences between myelinated and unmyelinated neurons (C.2.2.4)

• Explaining the importance of the sodium-potassium pump (C.2.2.2)

• Reflecting on EPSPs and IPSPs (C.2.2.7, C.2.2.13)

• Exploring how neurons detect pain (C.2.2.15)

• Considering how neural networks give rise to consciousness (C.2.2.16)

Great for formative assessment and encouraging metacognition, these tools keep your lessons student-centered and purposeful.

🔬 Section 2: Visualize & Explore – Interactive Activities

🎬 Depolarization & Repolarization Animation Creation

Students animate the phases of an action potential using digital or hand-drawn tools:

• Sodium influx during depolarization (C.2.2.8)

• Potassium efflux during repolarization

• Voltage-gated ion channel mechanics

• Local currents propagating the action potential (C.2.2.9)

By building and presenting their animations, students deepen their conceptual understanding and enhance their science communication skills.

🧠 Neural Signalling & Brain Chemistry Exploration Lab

This lab simulates advanced processes including:

• The impact of chemicals like caffeine or opioids on synaptic transmission (C.2.2.12)

• The interplay between excitatory and inhibitory neurotransmitters (C.2.2.13)

• Signal summation and its role in neuron firing (C.2.2.14)

• Perception of pain and consciousness as emergent neural properties (C.2.2.15–16)

This activity blends neuroscience with psychology and TOK, making it perfect for interdisciplinary exploration.

📚 Section 3: Practice & Assess – Quizzes and Exam Prep

📄 Multiple Choice Quiz + Paper 1A Practice (with Answers)

These resources mirror IB Paper 1 structure and provide clear explanations for each answer. Topics include:

• Resting membrane potential and ion channels (C.2.2.2, C.2.2.4)

• Saltatory vs. continuous conduction (C.2.2.11)

• Neurotransmitter release and summation (C.2.2.6–7, C.2.2.14)

• Effects of neonicotinoids and hyperpolarization (C.2.2.12–13

Example questions include:

• What ion influx triggers neurotransmitter release? (Answer: Calcium)

• What is the primary difference between EPSPs and IPSPs?

• Where are action potentials initiated? (Answer: Axon hillock)

These tools are ideal for classroom quizzes, homework, or review sessions.
