Your homeschool student can go over this material repeatedly until secure in the science being presented. Each experiment segment begins with stimulating questions that encourage thought and may provide for lively discussion. Once these have been answered, the answers complete with explanations provide immediate support for any concept not yet grasped. The experiments are real, not simulations.
Students collect the data themselves, point by point.
A running error estimate encourages precision in data collection. The data graph provides clear display of the data without errors in data plotting. Explanations of the graph, the likely sources of error and the units are available in the tutorial section. Suggestions for further exploration allow deeper understanding and broader comprehension. The Science Dictionary is constantly on hand to answer questions about the meaning of scientific terms.
