Science Topic 3 - Floating or Sinking

 Today at technology, we were learning about how something floats and sinks.

Firstly we were told to write down what was on the screen on a google doc. Next we watched a video about floating and sinking. The video was interesting and had new vocabulary, I learnt what buoyancy was, buoyancy is something that is sinking or floating. After the video our teacher Mrs Shamar asked us question about the vocabulary we learnt. The words we learnt is Density, Buoyancy, semi float and periscope. density is what size of a object is and the weight of it and periscope is what's used on a submarine and it's night vision. Semi float is when the object is half in the water and half above the water. In the video there was a man named Archimedes principle and the man was to find out a new project he wanted to work on and when he got into the water the water rises because he was more dense but if he was light the water would've never raised so he hopped out of the bath and ran out naked and screaming loudly. After the video we each had to pair into twos and we each had our own bucket to fill 2/3  full. Then we each grabbed an object and in total there was 11 objects, we had measure, weigh, composition(what's it made of), Predicting (if it float or not) and buoyancy results meaning if it floats or not. if a object is more dense it's most likely to sink but if it's less dense or has air it will float but if there's little bit of air it will semi float. Lastly we packed away our objects and emptied out the water and handed it over to Mrs Shamar.

Today at technology it was a fun experiment and was very enjoyable. The part I liked about the session was when we had to weigh the object and to see if it was buoyancy.
