Heart Jigsaw

Copy enough for one between 2 and cut into multiple pieces for children to use as a jigsaw

Diagrams of the heart

The arrows show how blood is pumped around the heart

Heart rate sheet for different animals, ages and levels of fitness

A child's heart usually beats faster than an adult's.

A healthy adult heart rate ranges from 60 to 100 beats per minute at rest A healthy child’s heart rate can range from 60 beats per minute while asleep to 220 beats per minute during vigorous exercise

Who/what? Heart rate in bpm (beats per minute)

Child (new born) 125 bpm

6 year old 100 bpm

10 year old 90 bpm

14 year old 85 (girl) 80 (boy)

Adult woman average heartbeat (note that a female heart tends to be smaller than a male heart)

78-82 bpm

Adult man average heartbeat 70-72 bpm

Athlete 30-60 bpm

Mouse 500 bpm

Large dog 90 bpm

Cheetah 120 bpm at rest to 250 bpm after a chase

Bear 40 bpm or 8 bpm during hibernation

Elephant 28 bpm

Teacher reference: factors that can influence heart rate include:

• Age

• Activity level (sleeping, resting, exercising)

• Fitness level

• Air temperature

• Body position (standing up or lying down)

• Emotions and stress levels

• Body size

• Medications

• Food and drink

• Illness

Heart rate challenges

Ask children to apply their heart rate knowledge and make a suggestion as to the possible heart rate under the following conditions?

1. A 4 year old child at rest (around 100 bpm)

2. The resting heartrate of an adult who is very fit (anything from 40-60 bpm)

3. The resting heartrate of an unfit adult (85 bpm plus)

4. The heartrate of a 10 or 11 year old after moderate exercise (120-140 bpm – though it will vary)

5. Whose heart might be beating at 125 bpm (a new born at rest; a child doing moderate exercise; an adult doing vigorous exercise)
