About this MicroSim

Allergic Reaction Signs Explorer is an interactive MicroSim for this health-education textbook.

Students identify the signs of an allergic reaction across the skin, breathing, digestive system, and whole body, and recognize which signs signal an emergency.

Use the controls in the panel below the drawing to interact with the model, then talk through what changed and why. The MicroSim is width-responsive and can be embedded in any course page with the iframe shown above.

Bloom's Taxonomy level: Remember (L1) — identify, recognize, list

Lesson Plan

Audience

This MicroSim is designed for Grade 5. For the K-3 bands the teacher typically drives the activity on a shared screen; older students can explore the MicroSim independently.

Learning Objective

Students identify the signs of an allergic reaction across the skin, breathing, digestive system, and whole body, and recognize which signs signal an emergency.

This activity targets Bloom's Remember (L1) (identify, recognize, list).

Suggested Use (about 10 minutes)

  1. Warm up (2 min). Ask students what they already know about the topic and let one volunteer describe what they see on the screen.
  2. Model it (3 min). Demonstrate the interaction once, thinking aloud so students hear the reasoning behind each choice.
  3. Guided practice (3 min). Invite students to try the interaction and to predict what will happen before they act.
  4. Discuss (2 min). Ask why the result came out the way it did, connecting the on-screen result back to the learning objective above.

Check for Understanding

Have each student (or pair) explain their result in one sentence, using the vocabulary from this chapter. Look for reasoning that matches the Remember-level objective rather than a lucky guess.

Bloom Taxonomy: Remember (L1)
Bloom Taxonomy Verb: identify, recognize, list

Learning objective: Students identify the signs of an allergic reaction across the skin, breathing, digestive system, and whole body, and recognize which signs signal an emergency.

Canvas layout: Full width (650px) illustrated figure with 8 clickable hotspots; bottom strip (100px) infobox showing sign and severity.

Visual elements: Flat-style illustrated person with hotspots at face/lips, skin (arm), throat, chest, stomach, whole-body icon (dizziness), plus a "Mild"/"Emergency" legend. Hotspots color-coded yellow (mild) or red (emergency).

Interactive controls: Click any hotspot to reveal sign/description/severity; "Show All Signs" button; "Reset" button.

Default parameters: No hotspot selected on load.

Behavior: Face/lips shows "Swelling of face, lips, or tongue — Emergency"; skin shows "Hives or redness — Mild to moderate"; throat shows "Throat tightness — Emergency"; chest shows "Coughing, wheezing, trouble breathing — Emergency"; stomach shows "Cramps, nausea, vomiting — Mild to moderate"; whole-body icon shows "Dizziness or weakness — Emergency".

Instructional Rationale: Remember-level objective, so click-to-reveal labeling builds a clear factual list rather than animation.

Implementation notes: p5.js; hotspot objects (x, y, radius, sign, severity, description) colored by severity; infobox renders in bottom strip on click.
