1. Lesson 3: Learn by heart
Today we will consider how heart rate patterns vary for different types of exercise.
Instructions on how to use this PowerPoint can be found on p.27 of the Teaching Guide, copies of which can be downloaded from

2. Lesson 3: Learn by heart Spot the 12 differences!
The twelve differences that the children should spot are:
1.The pens in Fizzy’s hair have swapped colours.
2.Fizzy’s fringe flicks in the other direction.
3.One Fizzy has an eyebrow, the other does not.
4.Fizzy’s eyes are a different colour.
5.One t-shirt has three horizontal stripes, the other has two.
6.One Fizzy has one wristband, the other has two.
7.One wristband has an extra yellow stripe.
8.The figure on Fizzy’s t-shirt is running in a different direction on each.
9.One pair of trousers has one button and the other has two.
10.One pair of trousers has a flap on the pocket and the other does not.
11.One Fizzy has laces in her front shoe and the other does not.
12.One Fizzy has her thumb tucked under her fingers on her clenched fist, and the other has it sticking out.

Subject: What we know so far.
Hello everyone!
Thank you for all your great work on heart rate and exercise. We’ve found out so much!
We can use everything that we have discovered so far to help other people learn about the heart. Why not make a list of everything you know about the heart and exercise?
Then, look at the next two slides about athletes’ heart rates, before reading my next for one last task!
Thanks,
Fizzy
Read through the with the children, then encourage them to make a list summarising everything they have learnt so far about the heart and exercise. This should include their findings from the investigations in lessons 1 and 2.

4. Lesson 3: Learn by heart
Example graph to show heart rate before, during and after a middle distance race.
Explain to the children that this graph shows an athlete’s heart rate during and after a middle distance race. They should notice how the heart rate rises quickly at the beginning, then remains steadily high while the runner maintains a fairly regular pace. Heart rate then rises again as the runner speeds up for the sprint finish (also due to the excitement of trying to reach the finish line first). The heart then slows back down to resting rate, more gradually than it rose at the start of the race, as the body recovers.

5. Athletes and scientists
Lesson 3: Learn by heart
Athletes and scientists
Scientists can help athletes to monitor their performance, include their heart rate, using specialised equipment.
Use this slide as a stimulus for discussing why athletes focus on their heart rate during training, and how scientists can help them. Points to cover may include:
-The more efficient an athlete’s heart, the quicker they will be able to get oxygen to all the muscles that need it, so that these muscles can perform better and for longer.
-Healthier hearts beat slower, even during intense exercise, which means that athletes can maintain a high level of exercise for longer before getting tired.
-Scientists can help by monitoring how efficient an athlete’s heart is, so that they know whether they are improving and know how and how much to train to get to the right level of fitness.

Subject: Heart rate quiz.
Hello everyone!
Well done for making your list of heart and exercise facts. I’m sure people will find it very helpful!
While you were writing that, I started to make up a quiz about heart rate, so that people can test what they know.
Could you help me by making up some more graph problems? First you’ll need to solve the ones I have already done!
Good luck!
Fizzy
Read through the with the children then see p.27 of the Teaching Guide for details of the activity. The graph problems quiz can be found on p.30 of the Teaching Guide.

7. From: Fizzy
Subject: Heart Beaters’ Club membership cards.
Hello everyone!
Thank you so much for all your help with my investigations. You’ve been brilliant, and we’ve learnt so much together!
As a reward, I’ve sent you each a Fizzy’s Heart Beaters’ Club membership card. Look after it and remember:
Stay fit!
Stay healthy!
Keep investigating!
Fizzy
Once the children have completed all the investigations in this unit, read through this together and present them with their Heart Beaters membership cards, which can be photocopied from p.32 of the Teaching Guide.
