- The digestive journey simDrag a meal from the mouth to the rectum. Each region shows its enzymes, its pH and how much starch, protein and fat is left, with live bars, a graph and a results table.
- Enzymes and pH: amylase and starch simPour a pH buffer into a tube of amylase, drag it into a 37 °C water bath, add warm starch and start the stopwatch. Drag the dropping pipette to the spotting tile every 10 s: the iodine stays blue-black until the starch is gone, then stays orange-brown. Fill a results table with pH, time to the end point and rate = 1/t, and plot your own graph of rate against pH.
- The heart and the cardiac cycle simDrag through one heartbeat on a front view of the heart in section. The chambers contract, the four valves open and shut as the pressures cross, and a linked graph shows atrium, ventricle and aorta pressure, with a results table to fill.
- The kidney and the nephron simDrag a drop of filtrate through one nephron, zoomed from the kidney. See what ultrafiltration lets through, what selective reabsorption takes back, and how water, glucose, urea and salts change, with a live concentration graph and a plasma, filtrate and urine table to fill.
- Breathing: the mechanism and a spirometer trace simThe student contracts the diaphragm and intercostal muscles on a model chest to make air flow in and out, then reads tidal volume, vital capacity and breathing rate from a spirometer trace at rest and in exercise.
- Yeast respiration and temperature simSet a water bath, settle a tube of yeast in glucose, count carbon dioxide bubbles three times at each temperature, plot the means to find the optimum and test the gas with limewater.
