My science investigation

Today in our science class we did our first investigation. we had to go get a smartwatch to see how fast our heart can pump. The first activity we did was sitting down and for that I got 109mmHg.  We also had to sit down for 30 seconds. Next we had to stand up and jog on our spot for about 30 seconds again for that I got 134mmHg After that we had to go get a tennis ball and throw it to your partner for 30 seconds again. Also for that I got 126mmHg. Then we had to stretch and do start jumps for 30 seconds. For doing stretching I got 126mmHg and for start jump I got 111 mmHg. Lastly I had to go outside and run as fast as I can for 30 seconds and for that I got 154 mmHg

 

Girls self - defence class

 Today the girls in year 7 and 8 from room 6 and 7 did self - defence class. We were sent to room 12 to our teacher Audrey. She was teaching us how to defence us girls from boys that are acting us or even someone older that is trying to kill us. We were really interested in her stories that she told us. We were also learning how to yell out if you need help.  She was also really fun to talk too. We were also learnt how to attack when someone comes behind us. My favourite part was when I learnt how to attack when someone was trying to pull me from the floor. At the end everyone got certificates. 

Osmosis and Transpiration

 First we had to fill up our conical flask with water up to 250ml. Also we had to up the celery. Next we had to choose what food colour to put in. So I chose red. We had to put 10 drops in the conical flask together with the water. Then we put in the celery, wrap a plastic bag on top of the leaves and tie it around.  Now we had to wait 30mins. After that we opened the bag up and the colours has went up the stem and changed it colours.
