Reaction times (Biology (14-18) eBook)Uses two push button switches and the timing function of EasySense to calculate reaction times. You can also enter the distance from stimulus to response to get speed of nerve transmission.
Reaction times (Biology (11-14) ebook)A controlled method to measure reaction times. Lets you investigate what may influence and what may not influence reaction time.
Hit the brakes! (Biology (11-14) ebook)A variation of simple reaction times. Creating a closer model of how reaction times, and responses to stimuli, influence stopping times in cars.
Hit the brakes (Biology (14-18) eBook)Extension of reaction times, uses a foot operated second switch to simulate driving a car. Use the simulation to show effect of distractions (e.g. using phone) on stopping distances.
Reactions (Science in Sport (11-18) eBook)The investigation records the simple reaction time. How reaction time is related to the environment that created it is the investigation for a sport science practical. It can easily be used to demonstrate how sport science can help athletes improve performance by saving thousandths of a second at each point.
