Footprints Science consists of simulations and interactives on many key concepts that are difficult to visualize and understand in Science. The site offers purchase of different modules or the complete collection. Samples, however, are free to use. Biology samples include "DNA drag and drop," "Kidney animation," "Fertilisation animation," and "Breathing animation." Chemistry samples include "Periodic Table interactive activity," "States of matter animation," and "Atomic structure activity."Physics samples include "Forces animation," "Power Station animation," and "Phases of Moon animation." Coursework includes "Variables," "Planning," "Graph," and "Line of best fit." More animations and interactives for each subject are available. The items are designed to be used with instruction to make the concepts more engaging. Interactives use drag and drop labeling with immediate feedback and allow pausing to stop the animation. Quizzes and games are also available. Graphics are very well done and easy to see, making difficult concepts much easier to understand. Interactives can be viewed as a large screen.
