A "Conversion Immersion" workshop was convened to provide a forum for instructors to work together to convert traditional "cookbook" laboratories to a more investigative format. This paper summarizes some of the ideas that emerged from the two sessions of the workshop, which included labs on the following topics: chick development, soils, antimicrobial agents, effects of pH and heavy metals on microbial processes, DNA isolation, immunohistochemistry, enzymes, osmosis, invertebrate diversity, plant diversity, microscopy and cells, muscle contraction, fermentation, and genetic engineering.

This activity (page 2 of the PDF) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance. Groups of learners will plan a Double Dutch jump routine and count the number of moves before the jumper trips. Then, learners test the routine while the jumper listens to slow music and again while listening to fast music. Learners collect data, produce a table comparing average performance per auditory stimulus, and consider the validity of their results. An optional extension activity asks learners to investigate how a strobe light affects jump rope performance. Relates to linked video, DragonflyTV: Double Dutch. Less

How Does a Touch Sensor Work?

Students learn about how touch sensors work, while reinforcing their similarities to the human sense of touch. They look at human senses and their electronic imitators, with special focus on the nervous system, skin and touch sensors. A PowerPoint® presentation explains stimulus-to-response pathways, how touch sensors are made and work, and then gives students a chance to handle and get familiar with the LEGO touch sensor, including programming LEGO® MINDSTORMS® NXT robots to use touch sensor input to play music. Students take pre/post quizzes and watch a short online video. The mini-activities prepare students for the associated activity. This lesson and its associated activity enables students to appreciate how robots can take input from sensors, and use that to make decisions to move. Less

Students' understanding of how robotic touch sensors work is reinforced through a hands-on design challenge involving LEGO® MINDSTORMS® NXT intelligent bricks, motors and touch sensors. They learn programming skills and logic design in parallel as they program robot computers to play sounds and rotate a wheel when a touch sensor is pressed, and then produce different responses if a different touch sensor is activated. Students see first-hand how robots can take input from sensors and use it to make decisions to move as programmed, including simultaneously moving a motor and playing music. A PowerPoint® presentation and pre/post quizzes are provided. Less

Reflecting on Human Reflexes

Students learn about human reflexes, how our bodies react to stimuli and how some body reactions and movements are controlled automatically, without thinking consciously about the movement or responses. In the associated activity, students explore how reflexes work in the human body by observing an involuntary human reflex and testing their own reaction times using dominant and non-dominant hands. Once students understand the stimulus-to-response framework components as a way to describe human reflexes and reactions in certain situations, they connect this knowledge to how robots can be programmed to conduct similar reactions.
