Operation Ouch! – Science Live Lesson

We take over the Operation Ouch! lab in this fun science lesson for 7-11 year-olds all about healthy hearts and circulation.

Dr. Chris and Dr. Xand van Tulleken explain where the heart is in the body, what it looks like and what it does to keep us alive and kicking. The twin doctors also share some helpful tips on how to keep our bodies healthy.

Dr. Ronke Ikharia (Dr. Ronx) also joins us to explore the circulatory system, the most reliable delivery service in the world!

Please note that this lesson was published in January 2023 and we are no longer reviewing emails and messages from schools for inclusion in the lesson.
