🌸 Hydrangea Flower Color Experiment
Hydrangea flowers change color based on soil pH. Acidic soil (low pH) produces blue flowers due to aluminum availability, while alkaline soil (high pH) produces pink flowers. Tap on a planter to plant a seed! All seeds are genetically identical, carrying the same pigment genes (delphinidin-based anthocyanins).
Acidic (pH 4)
Neutral (pH 7)
Alkaline (pH 10)
Results: pH vs Flower Color
Plant seeds and grow them to see results!
🦎 Temperature-Dependent Sex Determination
In many reptiles, the temperature during egg incubation determines the sex of offspring. Select an egg type below, then tap an incubator to place it. Watch how different temperatures affect whether males or females hatch!
Cool (26°C)
Warm (30°C)
Hot (34°C)
Results: Temperature vs Sex Ratio
Males (♂)
Females (♀)
