Investigating Factors Affecting the Heart Rate of Daphnia
What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...
Pocket Anatomy
Pocket Heart
An all-encompassing, fully interactive, gorgeously animated model of the heart can be used to teach cardiac anatomy, physiology, and even a touch of epidemiology.

Temperature Affects The Heart Rate
Learners relate heart rate and development to environmental conditions through experiment. In cooperative groups, students record the heart rate in developing zebra fish. Groups create a standard curve to predict the temperature at...

How Does our Heart Rate Change?
Pupils feel their pulse and describe it. They predict whether certain activities will increase or decrease their heart rates. Students use a heart rate sensor to determine resting heart rates and those after activity. In conclusion, they...

The Effect of Math Anxiety on Cardiovascular Homeostasis
Using a pulse monitor, learners will measure a resting pulse, take a math test, and then measure the pulse again. They analyze the change in pulse and compare it to performance on the test. This multi-purpose activity can be used in a...

The Heart Stopper
Use the pump from a spray bottle to drive a model of the heart in action! In addition to modeling the function of the heart and blood vessels, aspiring anatomists also simulate arterial blockage. They compare the effects of increased...

Listen To Your Heart Beat
Young scholars listen to their heart beats. In this biology lesson plan, students explore pulse rates and factors that cause them to change. Young scholars also construct both a graph to show variation in pulse rates and a simple...

Your Beating Heart - Circulatory System
Students illustrate a schematic circulatory system of a human body including heart, lungs, arteries, veins and capillaries. Next, students conduct an experiment to increase understanding of the relationship between heart rate/pulse and...

The Effects of Temperature Variations on the Heartbeat Rate of Daphnia
Young scholars use DigiScope technology to investigate Daphinia, popularly known as water fleas. They design, conduct, and report on an experiment to determine the effects of varying water temperatures on the heartbeat rate of Daphnia.

Circulation and Respiration: Vital Signs
What do your vital signs tell your doctor? An engaging hands-on lesson has your learners monitor their own lung capacity, blood pressure, and heart rate. They then connect the vital measures to the workings of the circulatory and...

Changes in Pulse Rate
Eighth graders practice making observations and collecting data after determining a baseline pulse rate then collect data on the changes in that rate with exercise. Students must organize their data and analyze their observations.
Curated OER
Cricket Dissection
Students conduct an experiment to test the effects of various chemicals on breathing and to practice animal dissection. They carefully dissect house crickets to identify the breathing structures and determine their rate of respiration....
Curated OER
Cardiovascular Homeostasis
Students develop and conduct an experiment to answer the question," How does cardiovascular exercise affect the pulse rate?". They record the changes to heart rate during different levels of exercise.
Perkins School for the Blind
Human Body Regulation
The human body can regulate itself through sweating and resting. Learners with visual impairments discuss how the body changes when it is under stress and what it does to regulate itself. To start, kids use talking thermometers to take...

Keeping Healthy Lesson Plan
Students explore how muscles work. In this health lesson, students identify how the blood supplies muscles with oxygen. Students participate in an online activity to reinforce the concepts.
Curated OER
Ins and Outs of Respiration
Students determine their respiratory rate and explore the factors that affect breathing rate.
Curated OER
The Circulatory System
In this circulatory system learning exercise, students review the functions of red blood cells, white blood cells, and platelets. Students label the parts of a human heart on a diagram. This learning exercise has 4 short answer, 13...

Drugs Change the Way Neurons Communicate
Students examine that certain drugs interfere selectively with neurotransmission, and realize that the effect of a drug is dependent upon dosage and route of administration.
Curated OER
Keeping Healthy
Learners exercise their muscles to explore concept of heart rate and to explain how blood supplies muscles with oxygen.
