STEM Launch with the Minister of Education

We were honoured to have the Minister of Education Richard Bruton launch the policy and implementation plan for STEM in education in Ireland. Minister Bruton had the chance to talk to come of the students about what they have been learning in science and maths. Here are a few pictures from the day.

Exercise and your Heart

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.

The Heart

We have been learning all about the heart in fourth class. Here are some interesting facts about the heart.

Did you know?

• The heart pumps blood to all parts of the body.
• The blood brings oxygen to the muscles.
• Heart rate increases with exercise so that more of the oxygen carried in the blood can reach the muscles.
• The fitter you are, the quicker your heart rate returns to normal.

• An adult’s heart rate is around 70 beats per minute, and a child’s is a bit higher.
• A mouse’s is about 500 beats per minute, and an elephant’s is about 25 beats per minute!
• Our hearts are pumping at a regular rate. This pumping can be felt by placing fingers across the pulse point at the wrist or the neck, and the rate can be counted.
• Your heart is about the same size as your fist, and weighs about the same amount as a lemon.
• Your heart is located in your chest, near your lungs, and to the left of the hard bone in the middle of your chest (the breastbone).
• Your heart is an organ made of muscle.
• The heart is an important organ in the body. It helps deliver oxygen and nutrients that are in the blood to all the other organs in the body.

Heart Rate Before and After Exercise

Today in our class we monitored some children’s heart rates before exercise and then we monitored it after exercise. We found out that your heart rate increases after you complete exercise. These are the results Name Before exercise After exercise … Continue reading →
