Cell & Body Explorer Tap the part named on a cell or body diagram — or name the part that is highlighted. Every answer tells you what it does. Food-Web Builder Build an ecosystem's energy flow — start with the producer, follow the energy up level by level, finish with the decomposer. Osmosis Lab Put a cell in fresh, salty, or matched water — predict which way water crosses the membrane, then reveal what happens to the cell. Dichotomous Key Identify a frog, spider, shark, or oak by walking a two-choice key — pick the trait that matches, step by step, until you reach the group. Put the Process in Order Rebuild photosynthesis, respiration, mitosis, or a life cycle by tapping the steps into the right order. Natural Selection Does a giraffe stretch its own neck and pass it on? Predict, get caught by the Lamarckian intuition, then watch evolution act across generations.
