What if your body got stuck in emergency mode? Students predict, then test what happens when the balance system breaks. They track feedback loops in a browser-based simulation and see the body sense a change, send a hormone, and reset itself back to balance. Scaffolded for SPED and ICT classrooms.

Students open the sim, pick a scenario, choose their reading level (Low / Med / High with Read Aloud), make a prediction, and watch the Balance Meter and the body respond. They record what they saw in a data table and use the patterns to explain how feedback loops keep the body in homeostasis.

📦 WHAT YOU GET (5 files, 24+ pages):

— 1 slide deck (8 slides) | vocabulary breakdowns included

— 1 student worksheet (hints, sentence starters, and word banks built in)

— 1 detailed answer key (sample responses included, distractors flagged)

— 1 A/B Choice handout (students circle the better answer)

— Google Drive Links

🎨 THE SLIDES: Every slide pairs the concept with a visual, color throughout. The lesson follows a consistent structure — Hook, Learning Target, Success Criteria, Key Vocabulary, Word Breakdown, What It Means, In Real Life, Turn & Talk. Vocab slides include images, syllable breakdowns, etymology, pronunciation, synonyms, antonyms, fun facts, turn-and-talk prompts with sentence starters.

🌐 SIMULATION: Runs in any browser on any device, no downloads, no logins. You'll find this sim and the rest of my free library on my teacher site:

🧩 BUILT FOR STUDENTS WHO STRUGGLE:

✅ Three reading levels built into the sim (Low / Med / High) with Read Aloud, so every student can access the content

✅ Word banks, hints, and sentence starters on every worksheet

✅ A/B Choice handouts — students circle A or B so writing doesn't block thinking

✅ Scaffolded reading with visuals throughout

✅ Data-first design — students collect evidence before writing

✅ Answer key included for every question

📚 TOPICS COVERED:

- Feedback loops and how the body senses change

- Homeostasis as the body's state of balance

- The thyroid and how it controls body speed

- Melatonin and the sleep cycle

- What happens when feedback loops break down

📐 Standards: NGSS MS-LS1-3 — Use evidence to argue how the body is a system of interacting subsystems composed of groups of cells.
