Handwritten family-album comic linking mitochondrial and chloroplast ancestry to bacterial relatives, supported by gene sequences, organelle genomes and translation machinery.

Endosymbiotic Theory: Organelles, Evidence and Gene Transfer

Review the evidence for endosymbiotic theory, trace membrane protein orientation and distinguish organelle function, gene transfer and bacterial ancestry.

Handwritten linocut comic with a goose chef showing a folded protein losing its binding pocket after heating while its polypeptide chain remains intact.

Protein Structure: Four Levels, Folding and Function

Compare the four levels of protein structure, folding and denaturation. Use amino-acid substitutions to build careful structure-to-function arguments.

Handwritten comic of a student in splash goggles and a friendly empty flask reviewing RAMP: recognize hazards, assess risks, minimize risks and prepare for emergencies.

Chemistry Laboratory Safety: Use RAMP Before You Start

Handwritten technical comic of a robot engineer comparing heat transfer through a saucepan body and insulating handle, with temperature, chemical resistance and rigidity requirements.

Materials Chemistry: Compare Structure and Properties

Chalk comic of four biomolecule characters: carbohydrates for fuel and structure, lipids for membranes and storage, proteins for enzymes and transport, and nucleic acids for genetic information.

Chemistry of Life: Biomolecules and Enzymes

Hand-drawn duck detective observes a bubbling beaker and asks for more evidence: bubbles alone do not prove a chemical reaction.

Scientific Reasoning in Chemistry: Observations, Models, and Fair Tests

Hand-drawn memory-cell librarian recognizes a microbe’s three-point antigen feature in a scrapbook, illustrating antigen-specific immune memory that helps a later response.

Immunity, Reproduction, and Development

Hand-drawn hormone signaling comic compares a cell with a suitable surface receptor and one without; response requires the right receptor and cellular machinery.

Nervous and Endocrine Control of Movement

Handmade felt comic pairs lungs exchanging oxygen into blood and carbon dioxide out with a heart courier driving blood flow, showing their distinct roles in oxygen delivery.

Transport and Exchange in the Human Body

Hand-drawn hedgehogs stand in woodland patches separated by roads and fields, showing how habitat fragmentation can disrupt wildlife movement and connections.

Human Impact, Climate, and Biodiversity

Hand-painted pond snapshots compare same-species frogs as a population with frogs, a snail, a dragonfly, plants and fungi representing an ecological community.

Populations, Communities, and Biomes

Hand-sketched axolotl watches a DNA gel with negative wells above and a positive electrode below; a 200-base-pair fragment travels farther than a 900-base-pair fragment under the same suitable conditions.
