Exercise and your Heart

This slideshow requires JavaScript.

In fourth class we have been busy testing our heart rates. Before exercise we tested children’s heart rates using the heart rate monitor. After the exercise we tested them again to see if there was any change in their heart rates. The heart rate monitor told us how many times their heart beat per minute (bpm). Here are some of the results we collected.

Results

Kalya                Before exercise 96bpm

                          After exercise 120bpm

Oliver                Before exercise 90bpm

                           After exercise 130bpm

Declan              Before exercise 78bpm

                          After exercise 135bpm

Oscar               Before exercise 150bpm

                          After exercise 200bpm

 Conclusion

We found out that your heart rate changes after exercise. It beats faster. Oscar had a high heart rate before exercise and we know this was because he was nervous and excited about using the heart rate monitor. He was also doing a lot of talking at the beginning!!

For the next few weeks we are hoping to use the heart rate monitor before and after P.E every week.

We have been learning about the effects of heat. A few weeks ago we made play-dough in our school kitchen. Last week Tristan used play dough to make a model volcano. Ms. McGinley has been teaching 4th Class all about … Continue reading

Science Week in St Clare’s PS

Science week is upon us and on Wednesday the 12th of November we will hold our annual Science Week Exhibition. Parents and family are invited to see all of the fantastic science and mathematics work that the pupils have been working on since September. This year the fourth, fifth and sixth classes are also entering the Intel Miniscientist for the first time. A judge will be attending on the day and will assess which class will go forward to the regional finals. Having seen some of the investigations prior to this I think that this is going to be the best Science Exhibition that we have held so far!
