One of the goals of secondary science education is to help students develop skills related to scientific inquiry. However, the results of previous studies have shown that students have difficulties in identifying problems, formulating hypotheses, drawing conclusions, and designing experiments. The main objective of this contribution is to indicate…

We introduced a microfluidic paper-based analytical device ([mu]PAD) to undergraduates majoring in nutrition education using a modified acid-base titration on paper microzones. After designing experiments for sample analysis using micro acid-base titration, students fabricated the devices and implement the experiment as designed. Then they…

Describes a variation of "the suffocating candle" activity used to develop the process of predicting based on reliable data. Instead of using jars of varying sizes under which the burning time of candles is measured, the same jar is used while the candle is elevated on varying numbers of blocks. (CS)

Describes a class project in which students determine the best brand of paper towel in several categories. The activities and experiments completed during the project foster observation, measuring, collecting, data evaluation, writing, and mathematics skills. (BC)

Presents a demonstration of wave behavior, and experiments of (1) the determination of the mechanical equivalent of heat, and (2) a "discovery" investigation based on the maximum-span staircase. (CS)

Identifies specific science skill activities and discusses how they can be enhanced using the microcomputer in a laboratory setting. Highlights the benefits, advantages, and applications of microcomputers in physics laboratories. (ML)
