Why does your heart beat faster when you run around for a while?
Ask children to feel for their heartbeat to see (roughly) how fast it is beating. Then, using an open space, ask them to jog on the spot for a minute or do star jumps. Ask children to feel for their heartbeat/pulse again and then respond to the big question on the slide. Ask the children if they know what it is which makes the heart beat faster or slower.
Presentation - starter slide.
Stopwatch / timer.
Run through the presentation on the heart and how blood is pumped around the body. You could also introduce some other activities here, such as explaining what a stethoscope does, timing heartbeats in one minute and comparing heartbeats.

Answer questions and take part in activities during the presentation.
Stop the presentation at the relevant slides: Talk Partners; AfLs; Songs.
Take part in the Choral Response Questions activity (see Assessment section) after the Keywords/Rocket Words slide.

Today's expert film is with Mike Linley, who talks about the human heart and gives some fascinating facts about hearts of various animals.

Modelling the Heart
Watch the Mission Assignment film.
The first activity is to study the diagram of the circulatory system. Try to describe the journey the blood takes around the body, as if you were commentating on a motor race.
Secondly, clench and unclench your fist for one minute. Think about that movement and the muscles you are using. Discuss how this process is similar or different to how the heart pumps blood around the body.
A further activity uses the Handout which shows a diagram of the heart. Children should be directed to label the different parts of the heart. To stretch further, they could explain the function of different parts of the heart. There is an answer sheet available for this task.
Simple Heart
Watch the Mission Assignment Film
Ask the children to colour one side of the bag with the red pen.
Next, get them to cut the pipe cleaners to different lengths, under adult supervision. It would be helpful to have a picture of the heart available so children can refer to it for sizes, etc.
Again, with adult supervision, ask the children to glue the pipe cleaners on to the bag. Ask what they are representing? (veins and arteries).
Next, ask the childen to insert a red and blue straw into the bag and zip it up. The children should gently blow into the straws to make their model heart beat.
Mission to Write! Blood Drop Diary
Use Handout - Mission to Write! Blood Drop Diary to help with this task.
Today's extended writing task's purpose is to inspire the children to recall the learning in the lesson in a fun way. They should pretend they are Billy the Blood Drop and write a diary entry (in the first person) to describe in several sentences how Billy travels around the body. Encourage the children to use the words associated with the task as found on the Handout and to be as accurate as they can with spelling, punctation and grammar.

Handout - Mission to Write! Blood Drop Diary
Using the Handout, ask the children to label the parts of the heart. They could make labels for their own model heart too.
Quiz
With their talk partners, the children are to go through the quiz at the end of the presentation and answer the questions.
Formative Assessment Forms
Students are to complete these forms where present.
Assessment Trays
Ask the children to place their Handouts, notebooks, Formative Assessment Forms, and/or Investigation Sheets, into either the Discovery tray (green) or Explorer tray (red).*
Explain that the green tray means that the learner has understood the lesson well, and that the red tray means that the learner needs more time to practise.
* use whichever colours of tray you have in stock, or prefer to use for this.
Children can take an interactive assessment quiz to test lesson comprehension. These can be found in the pupil area on the website.

The Science Behind the Science
The heart is one of the most important organs in any animal. It is essential that fluids circulate throughout the body, through a system of veins, arteries and capillaries in higher animals and a simple system of tubes in simple animals.
In either case this forms the circulatory system and the heart is the pump that keeps blood flowing. If the heart stops then death will quickly folllow.
However, in humans, heart transplants are quite common provided that the patient can be kept alive long enough to receive the donor heart. This may mean using a mechanical heart in the meantime and smaller, portable units have been developed to allow mobility in the patient.
When mechanical hearts are used this is often in addition to the patient's own heart and, sometimes, the doctors have noticed that the failing heart begins to recover, having been given a period of rest.
Recent studies have revealed the remarkable ability of the heart of the zebra fish, from the rivers of the Amazon, to self-heal when damaged. Researchers are now isolating the gene responsible for this which could lead to significant advances in the treatment of human heart disease.
