Sense Organs and Reflexes
by Anonymous
Choose the path a signal travels to time reactions, then adjust the iris, lens, and skin temperature to see why reflexes beat thinking and senses can deceive.

About this app
Sense Organs and Reflexes is an interactive middle school science app about how the eye adjusts to light and focus, how reflex signals travel, and why temperature sensations can differ. Explore three tabs by adjusting pupil size and lens thickness, choosing a reflex route through the spinal cord or brain, and comparing hand sensations after exposure to different temperatures. Built-in scenarios, values, feedback, and reset/next controls turn each topic into a short hands-on investigation.
Use cases
- Middle school students studying stimuli, responses, and sensory organs
- Teachers demonstrating eye accommodation and pupil control
- Learners comparing reflexes with conscious reactions
- Students investigating temperature adaptation through interactive choices
Features
- Adjust pupil size and lens thickness for dark, bright, near, and far viewing scenarios
- Compare reflex and brain-mediated signal routes for the hand and foot
- Display calculated signal times, including the added brain round trip
- Choose starting and shared-water temperatures for both hands
- Show how the same water can feel different depending on each hand’s prior temperature
- Progress through four guided missions in each topic with feedback and reset controls
