We learned how to take our pulse in the past week. 

We estimated our resting heart rate and what our heart rate would be after two laps of the school yard.

Watch our short video to see how it went!

We learned about temperature this past week.

We estimated the temperature in our class, in the shelter, in the yard and at the front of the school.

We worked in groups and used thermometers to measure the temperature in these locations.

We then recorded the temperature on sheets and figured out how accurate our estimates were.

A magnet attracts metal. Magnets have poles. The earth is a magnet and electricity is created using magnets.

We have been investigating interesting facts like this during the month of October. 

Magnets have a huge role to play in our daily lives.

The Unburstable Balloon Experiment!

An tUasal Táth, Eolaíocht, STEM  Tagged , 1 Comment »

You will need: 

  • Four balloons 
  • Matches 
  • An adult 
  • Water 
  • A candle 

Steps: 

  1. Inflate two balloons with air.
  2. Inflate two other balloons with air and 100ml of water. 
  3. Light the candle. 
  4. Place the balloon with air over the flame. 
  5. Place the balloon with water over the flame. 
  6. Dry up the water and tidy away the experiment. 

Findings: 

The balloons inflated with air explode very quickly. The balloons inflated with air and water explode eventually but after a much longer period of time. The water conducts the heat from the candle and absorbs the heat energy. Once the water gets really hot, the balloon eventually explodes. 

Pancakes cooking on a frying pan are cooked by conduction. Steaming vegetables are cooked by convection.  Marshmallows over an open fire are cooked by radiation. 

Drumlease National School is a Science, Technology, Engineering and Mathematics (STEM) school.
