Measuring Reaction Time— Super Value Laboratory KitThis activity uses a unique reaction time strip that lets students measure one type of reaction time and learn that reaction time varies from one person to the next and there is a limit to reaction time speed. Students experiment with the effect of sight and sound on reaction time. Other reaction time experiments can be performed after estab-lishing the basics with this hands-on kit.FB1571 I $22.15MIDDLE SCHOOL LIFE SCIENCEHUMAN BODY, CONTINUEDHuman Reflex Study—Super Value Laboratory KitStudents perform five tests to observe the innate reflexes the body performs to maintain homeostasis. Reflex tests include the patellar, Achilles, Babinski, pupillary and blink reflexes. Includes enough materials for 15 groups of students and five reflex hammers. All materials are completely reusable.FB1988 I $40.40Human Senses—Student Laboratory KitTaste, smell, hearing, sight and touch are explored in a series of fun, safe activities. Students are amazed when they determine their dominant eye, find their blind spot, are unable to sense things on their skin and cannot taste some common food items. FB0439 I $88.65Reaction TimerBattery powered, portable and lightweight, this digital timer measures reaction speeds to hundredths of a second. Send stimuli as light, sound or touch, and students hit a switch in response to the stimulus so the LED display shows their reaction time. Experiment and have students determine what type of stimulus consistently provokes the fastest response.FB0059 I $207.85Action/Reaction LabInvestigate specific nervous system functions, including response times to light, sound and touch; effects of fatigue on reaction time; benefits of reaction time training; and hand-eye coordination. Includes reaction timer, coordination game board and pieces, record-keeping wall chart and teacher’s guide.FB0054 I $282.45
