In this activity (1st on the page), learners conduct a series of tests to find out which of their hands is more dominant. In other words, are they right-handed or left-handed? Learners work in pairs and observe each other doing simple tasks like writing, cutting, and throwing a ball. They collect data to draw conclusions about their partner's handedness. This resource also includes two questionnaires about the strength of handedness as well as an online and offline test for handedness.
