Grow Green

Recently we went back to tech, instead of working with sugar this time our experiment had to do with plants specifically leaves. We talked about the structure of a leaf, the ones we are able to eat and how they grow. 

For our experiment we each used different leaves we could find outside our classroom and then boiled them in a tube of alcohol to see the colour drain out! From one tiny leaf there was definitely a lot more pigment than I would have expected. Some of us even got the chance to find out the meaning of words like photosynthesis!

Working With Sugar

For this weeks lesson we were working with sugar, talking about the different types and getting the chance to experiment with some coke.

Apparently, we are only supposed to be consuming 5 to 6 grams of sugar but instead we decide to have more sugar and end up having about 96 grams per day. Too much sugar can give you type 2 diabetes! Type two diabetes is when you have to get insulin shots to keep your blood sugar normal. Type one is when it comes from your genes. 

During the experiment we boiled the coke in a beaker, around 15 minutes after the coke evaporated we could see the amount of sugar that we have in one cup of coke.

Bones & Skeletons x2

This week we were labeling parts of a skeleton and sketching. We had to cut out each part, glue it in our book to look exactly like the human skeleton and label using either the scientific name or common name. Before we got around to gluing the teacher had to check and see if the bones were in the right place.

After completing the first task our next instruction was to sketch one of the bones Mrs Sharma let us borrow. I was quite nervous because Mrs Sharma said that some of the bones were real but didn't tell us know which ones. Personally I'm not the best drawer so I went with the classic easy dog bone.

Making A Circuit X2

For our 5th topic we were making a bit more advanced circuit. This time we were using a voltmeter and a switch to see how high the energy was. It was quite confusing at first because we had so many wires so honestly I just improvised. Getting the switch and voltmeter to work was definitely the hardest part to get right. I had to rearrange wires this way and that way for it to finally work. 

Everybody then had to draw a diagram of their circuit with the amount of wires they used, personally mine looked decent. 

Saving Energy 🔌

This week's topic was about saving energy, we had to list things and places that use quite a lot of energy. Our list included phones, malls, the airport and the hospital too. For our experiment we had to make a bulb light up using two wires, a battery and a bulb circuit. I learnt that for the bulb to light up you have to put the positive wire with the negative. 


Once we completed our experiment we watched a clip  about how we can decrease our use of energy, in the video it talked about how heat rise from global warming can destroy earth and people should carpool to use less energy! 

As we know Thomas Edison was the first person to create a light bulb, but over the years people have made other less energy using versions like the LED. The LED uses 85% less energy and can last 15 years or longer!!
 

Earthworms

Our focus for our class yesterday was to do with earthworms. We discussed what the worms do for our garden and how they give nutrients. Mrs Sharma then gave us about 4-5 worms to look at, we had to write about how they behaved outside of the dirt and measure their size.

Before we took a look at the earthworms we watched a video and had to write down at least 5 new words we learnt. In the video there was a girl named Emma, she said that finding earthworms were her passion. A life hack she gave was, if you mix mustard powder and water then put it in the soil the earthworms's skin gets irritated and they rise to the surface.

PLASTIC !!

Our first topic for science was plastic, we discussed what single use, recycling and reusable plastic was. Single plastic is when you can only use it once, recycling is taking something and making another thing out of it and reusable plastic is just being able to store things in it continuously.

Each of us received our own science project book, in our books we write down things from our class and have to make sure we keep it up to date. Making sure we don't lose it is also important because it is our responsibility! Mrs. Sharma made us watch a video about plastic and how it's travelling to our waters, some people even learnt a new word - Biodegradable. Biodegradable is a type of plastic that can be decomposed meaning it can break down into the soil and gives it nutrients.

Science 🔮

Today we had our first lesson of science for tech basically an introduction, unfortunately we couldn't do it in person but at least we still got to have a class. We talked about 3 different areas of science (chemistry, biology & physics). Our teacher Mrs. Sharma made us watch a video about a lady named Alex Dempsey, she is a coral reef ecologist. An ecologist is someone who studies about the environment as well as people and animals!🐬

I am looking forward to being in science for the next few weeks, to learn something new and try out experiments and things like that. Mrs. Sharma is a good teacher so I'm positive I'll enjoy learning in science class!! I can't wait to start experimenting with a bunch of random things.😁
