Informations sur le produit "Reflex Hammer Accessory Kit"

Das Reflexhammer-Zubehörset verwandelt Ihren Kraftsensor in einen Reflexhammer. Verwenden Sie es, um den Hammerschlag auf eine Sehne zu erfassen. Bei Verwendung des Kits mit einem EKG-Sensor zur Aufzeichnung von EMGs können die Schüler Reflexe untersuchen. Durch Vergleichen des Zeitpunkts des Schlags mit dem Zeitpunkt der Muskelaktivität können die Schüler die Zeit berechnen, die für das Auftreten eines Reflexes erforderlich ist.

Dieses Kit enthält

Weitkegeliger Kopf
Schmal zulaufender Kopf
Halterung
Griff

Bildungsstufe:	Sec. II & tertiaire, cycle 2
Fach:	Vernier, biologie

Biology with Vernier (EN)

Biology with Vernier is the foundational biology book for high school and college courses. Biology with Vernier has 31 experiments in cell respiration, photosynthesis, membrane diffusion, osmosis, human physiology, transpiration, fermentation, and other important biology concepts. The complete table of contents is shown below. Experiments are included for 12 Vernier biology sensors. If you teach Advanced Placement (AP), International Baccalaureate (IB), or college biology, you should also consider Advanced Biology with Vernier (BIO-A) and Human Physiology with Vernier (HP-A).

Go Direct® EKG Sensor

The Go Direct EKG Sensor measures electrical activity in the heart and electrical signals produced during muscle contractions. The wireless options minimize the concern of cables getting caught and tangled during experiments. This sensor provides two separate outputs: one optimized for standard 3-lead EKG tracings and one optimized for surface EMG recordings. EMG recordings can also be rectified automatically by the sensor. The Go Direct EKG Sensor can be used in a variety of experiments: Compare and measure students’ electrocardiogram (EKG/ECG) waveforms. Determine heart rate by examining the number of QRS waveforms in a series of electrocardiograms (EKG/ECGs). Study contractions of muscles (EMG) in the arm, leg, or jaw. Correlate measurements of grip strength and electrical activity with muscle fatigue. Rechargeable Battery—Ready When You Are The Go Direct robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from our free Graphical Analysis™ 4 app. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students. Wired or Wireless—The Flexibility to Choose Our Go Direct sensors connect directly to your mobile device, Chromebook™, or computer using our free Graphical Analysis™ 4 app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth wireless technology, allowing you to choose the solution best for your classroom or laboratory.

Human Physiology with Vernier

The 24 experiments in Human Physiology with Vernier are designed to encourage students to think about the physiology of various human organ systems by measuring the activity of the upper respiratory tract, the lungs, the heart, the nervous system, and the musculoskeletal system. Homeostasis is an underlying theme, and several experiments illustrate the response of the human body to stress or external influences.
