“I have read it three times, and I still cannot tell you what happens after the spinal cord.” When a topic is a path, words in a long block can hide the order.
This page belongs to the SPM Biology help pages. The example comes from coordination and response.
When does a sketch beat another paragraph?
A path has a start, a finish and steps in between. A flow diagram puts them in a line, so you see the order at once. A paragraph hides the order inside sentences.
Topics such as reflex actions, the path of air, and the transport of water in plants are paths. Definitions and comparisons are not.
One example: a reflex arc as a flow
This original flow is for touching something hot:
| Box | Label |
|---|---|
| 1 | Stimulus: heat on the skin |
| 2 | Receptor in the skin detects it |
| 3 | Sensory neuron carries the impulse to the spinal cord |
| 4 | Spinal cord passes the impulse on |
| 5 | Motor neuron carries the impulse to the muscle |
| 6 | Effector: muscle contracts, and the hand is pulled away |
Then write a caption of two sentences: what detects, what carries the message, and what responds. “The receptor detects the heat, and a sensory neuron carries the impulse to the spinal cord. A motor neuron then carries the impulse to the muscle, which contracts, so the hand moves away.”
Six boxes replace a page, and the caption turns them into exam wording.
What can I do on my own?
Before you write more notes, ask: does the topic have a start, steps and an end? If yes, sketch it.
- Draw boxes with arrows and use one or two words in each box.
- Close the notes and redraw from memory.
- Write a caption of two or three sentences below the sketch.
If the topic is about why or how things differ, use a table instead.
When might one-to-one tuition help?
If your sketches are correct but you cannot turn them into written answers, it helps to explain each arrow aloud to someone who asks questions. A one-to-one teacher can do that and point out where a sentence needs a reason.
Free tools such as the claim evidence revision desk help with wording. See online one-to-one Biology tuition if live feedback would help.
