Family tree

 

Today my class had to do a family tree. My family tree on my dads side doesn't go back far because I rarely visit my tongan side, but with my mum's side my Great Grandmothers, Great Grandpas, nanas and papas all live in the same house. I don't really know my Great Grandmother and Great Grandpas parents.

Science: Bubble Science

 Technology today was fun because we were making bubbles.

Firstly we watched a video about how to make bubbles, the bubbles are made from water and soap. The water and soap are layered soap then water and another layer of soap, also the soap can have different colours if it reflects from the sun. if you use different shapes of wands it will still be shaped as a sphere because the air inside the bubble keeps its shape but there was no water inside the bubble will flop.

After watching the video we made our own equipment and liquid. Firstly we used the beaker and filled up half which was 125ml with water. Next we used a spatula which looks like a spoon and had to weigh 5 grams of sugar and tip it into the water. After we've tipped the sugar into the beaker we stir the sugar until it dissolves. After the sugar dissolves we went to another and used detergent and glycerol to make our bubble liquid. Firstly we used a syringe to suck up 10 ml of detergent and 3 ml of glycerol.

Mrs Sharma gave us three straws two small and 1 big straw also she gave use a wire type thing to us. We used the wire type thing you shape it into a circle wand and dip it into the liquid and blew bubble. The first task we done was very difficult for some of us because we had to make a caterpillar. The caterpillar was hard because the bubbles kept on popping. Also the different types of bubble no one could create was the cube bubble and the carousel. Only one of the student could make the cube bubble.

Today at technology was very fun and interesting because blowing the bubbles were fun to make but difficult at the same time.

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.
