This challenge game was created in powerpoint. It has 5 categories (Inference or Observation, Steps of the Method, Vocabulary, Quantitative or Qualitative and Variable or Control)with 5 questions each. It is a great review for a scientific method unit and my students have always loved playing it. Make sure to click on the number value (ie. "200") in order to advance to the correct slide. If you click elsewhere in the box it may not advance to the correct slide.
