Natural Disasters Survival Kit

 

We were learning the important stuff we need if a natural disaster occurs, for my poster I did a torch, canned beans, apple, drink bottle, medical kit and a radio, I really enjoyed making this and I think mine is fantastic. 

 I found it easy to create the medical kit because all you hat to do is make sure its the right size, make sure it has the right words on it and also make sure it has the right colour. 

 I found it hard to polyline the radio because when I outlined it in the picture, it had so much detail. 

 Next time I will try add more accessible things.

Cold Air Balloon Observation Part 1 and 2

 During science, we we're learning about what an endothermic reaction, we made one by filling up a balloon with baking soda, vinegar, a measuring cup and a bottle. When we added the baking soda and the vinegar it caused a chemical reaction, causing the balloon to inflate.

What happened? When vinegar and baking soda mix, an endothermic reaction occurs. This produces carbon dioxide which inflates the balloon. The endothermic chemical reaction will also lower the temperature in the area surrounding the vinegar and baking soda so significantly that you will be able to easily notice the change in temperature.

I observed/predicted that when the baking soda and the vinegar mix, the balloon will blow up so much that it'll pop, luckily it didn't happen because if it did, most of our chromebooks would be affected by the mix.

We tested it and it didn't go as good as I expected it to be, when Mrs Bava attached the balloon to the milk bottle, it had a slight rip in it, that's what caused it to splat everywhere. 

Here is a video to learn about it:

Balloon Madness!

 During science, we we're learning about Isaac Newton's third law of motion, he said that for every action, there is an equal and opposite reaction, so we tested it with rocket balloons, what you'll need: Tape, String, paper straw, balloons. My group and I was testing it and our results didn't go so well, we failed I would say.

I found it easy to create the structure because all you needed we're straws, balloons, string and tape, also make sure your string is nice and straight and you have a very firm grip on it.

I found it hard to figure out why my balloon didn't turn out how I was expecting it to turn out, it just kept on twirling around and around, Vinzent thinks that if the balloon has less air in it, the faster it'll go, I should of tried that in the first place.

Next time I will sort out what will go right and what will go wrong in this experiment because I think I was more on the 'it will go wrong' side.

Here are some photos during the process:

 

Persuasive Writing

We were learning about writing a persuasive writing on if we agree or not to be prepared for an unpredictable natural disaster, I think I went on pretty well after I checked it when it was printed, I was pretty impressed of my writing that I did this term. 

 I found it easy to paste the persuasive writing from the document into the slide because all you had to do is copy and paste every paragraph into the slide and just change the backgrounds and page setup. 

 I found it hard to gather all the evidence I could because I had to look on a lot of different sites, I didn't even know that Civil Defence had all the information, I maybe didn't check properly. 

 Next time I will try make a better descriptive piece of writing in term 4, I hope it's a different topic so I can either find it easier or harder.

Milk And Food Colouring Science

 During science, we were learning to make a multi coloured milk food colouring separation, we put some soap onto a cotton bud and put milk into a bowl, we added a couple drops of food colouring and saw the reaction when we put the cotton bud that had glue on it mix with the milk and food colouring, it was separating and curling up.

I found it easy to add some drops of different colours of food colouring because it was simple, we we're all sharing them around and it only took like 3 minutes to fit all of the colours into the bowl of milk.

I found it hard to make the cotton bud with glue on it stay on the surface of the milk because Mrs Bava said to keep on the surface otherwise it'll ruin it, I sometimes accidentally dipped it too deep into the milk.

Next time I will be more careful of my bowl because I sometimes spilled a bit on the deck which causes the deck to stink.

Lava Lamps

During science, we we're making lava lamps, we put oil into an empty cup and then put water inside the cup and somehow it wasn't mixing, because the oil was lighter than the water, it doesn't mix because of intermolecular polarity, we added some drops of broken Aspro Clear tablets, they sank to the bottom and was sort of fizzing.

I found it easy to add my drops of Aspro Clear tablets, because all you had to do is just break them into halves, or even quarters, and just insert them into the cup of oil and water.

I found it hard to know the right amount of oil and water because when I poured it in, it looked like I poured a bit more oil than the water.

Next time I will try add more Aspro clear tablets into the cup such as breaking them into more pieces to make the fizz and bubbles even more better.
