Natural Disaster Survival Kit

In reading we have been learning about natural disasters and tsunamis. our create activity for reading was to make a survival kit for a natural disaster. I used my thinking and ideas from my persuasive writing that you can find somewhere on this blog. I found it easy to make my tems using the polyline tool, and to trace around images that were too hard to do on my own. I found it challenging to polyline my radio. I got something so simple to do and somehow make it so hard. I could of just made a brick with some buttons but instead I made a full on Sony radio, with a boombox speaker. I enjoyed learning about natural disasters and making this kit. Now I know how to be safe and how to be prepared for a dangerous disaster. Next time I will hand my mahi in on time, and spend less time making the picture look pretty.

Balloon Rockets!

Newton's first law of motion describes that every action has an equal and opposite reaction. We taped a balloon to a straw that was on a smooth piece of string. Be blew up the balloon and let go. The pressured air pushes the balloons along the string. We found out that if the balloon was smaller it was more aerodynamic and was faster along the string. If the balloon was trying to go up on an incline gravity would hold it back and it would just fall back down. Some of the balloons didn't even move. They just went a small distance then spun around the string.

To do this experiment you will need:

A Balloon.

A piece of smooth string, around 2m long.

Half a straw

Some tape

Cold Air Balloon!

When baking soda and vinegar mix, it makes something called an endothermic reaction. This makes carbon dioxide bubbles that can inflate a balloon. It also lowers the air temperature in the ballon, making it colder. If you feel the bottom of the ballon it will be much more colder than it was before. This is very easy to do. And you can even go do it now, you should have the ingredients in your kitchen.

To do this experiment you will need:

A balloon

One cup of vinegar

One tablespoon of baking soda

One funnel

One bottle

First you put one tablespoon of baking soda inside of your balloon using a funnel. Next you put your funnel on top of your bottle and put your one cup of vinegar in. Remember to wipe any excess baking soda off the funnel. Next you stretch the balloon on top of the nozzle of the bottle trying not to get any baking soda into the vinegar. Then once the balloon is stretched over the nozzle of the bottle tightly you can poor the baking soda in. And ABRAKADABRA the balloon should start to fill up with carbon dioxide!

Part 2:

We did a way bigger version of this last Wednesday. We did 4 cups of vinegar and 8 tablespoons of baking soda. It was quite tricky to get the baking soda into the ballon so that was the first problem. Then we had to stretch the balloon over the big nozzle of the milk bottle. When we tipped the balloon over the baking soda dropped into the vinegar. The reaction cause carbon dioxide bubbles like it should do, but then the liquid went up into the balloon! By now the balloon was kinda breaking and the liquid was spraying out of the bottle. I went and felt the vinegar and it was really cold because of the endothermic reaction.

Part 3:

We did and even bigger version of the cold air ballon. We got a super pump water bottle and filled it up. We didn't even measure how much ingredients we used. We used a jumbo balloon so it will fill up with lots of air. It didn't pop but it got very very big. We filled the balloon and the bottle up to the brim and chucked them together and it instantly started to react with the endothermic. We felt the balloon and it felt very tight and cold. I hope that we may be able to do a part 4 with a bigger bottle and bigger ingredients.

I Am Poem

We were learning about how to write a I AM POEM. An I am poem is about you and your interests. Like what you want and what you say. You describe these things about yourself bu sing adjectives or verbs or other descriptive language. I enjoyed polylining my face. I was originally going to do an old photo but this brand new photo was better. I don't really like doing %100 my facials so I ad a bit of cartoon in there. I found it easy to make the edge of my polylined face look like mine. I used the zoom tool to make it look like the edge of my head so it looks a little bit real. I found it challenging to think of my I am's. I left a few out because I don't do some of the things like pretend. But I changed a few because a few of them actually happened

2021 Persuasive Writing: Is It Important To Be Prepared For A Natural Disaster?

We were learning about writing a descriptive piece of persuasive writing, and to persuade somebody into thinking that our idea is the right idea. I enjoyed making my publishing and polylining my equipment like my radio and my thumbs up, because I love to polyline my pictures. I found it easy to piece it together and research with the sites recorded on my Persuasive Writing Reference page. I found it hard to get going with my planning. I took a bit to think of some topics for my persuasive writing, but my head just wasn't ticking properly.  Next time I will try to jot my ideas down on my planning and brainstorming, and to think of my topics faster. It took me an entire writing session to think of my three topics for my writing. So next time I will get my ideas down faster.

Milk And Food Colouring Explosion!

In science we put  milk and different coloured food coloring in a bowl and put a drop of dish soap in the milk and the colours went into the sides of the bowl. At some point we all have done this or seen it on youtube. But how does it work? Milk is mostly water, but it also contains vitamins, minerals, proteins, and tiny drops of fat floating in solution. Fats and proteins are sensitive to changes in the milk. The secret of the bursting colors is in the chemistry of that tiny drop of dish soap. Like other oils, milk fat is a non-polar molecule and that means it doesn’t dissolve in water. When the dish soap is mixed in, however, the non-polar (hydrophobic) portion of micelles (molecular soap structures in solution) break up and collect the non-polar fat molecules. Then the polar surface of the micelle (hydrophilic) connects to a polar water molecule with the fat held inside the dish soap micelle. Thanks to the dish soap connection, the non-polar fat can then be carried by the polar water. This is when the fun begins. The molecules of fat bend, roll, twist, and contort in all directions as the dish soap molecules race around to join up with the fat molecules. During all of this fat molecule gymnastics, the food coloring molecules are bumped and shoved everywhere, providing an easy way to observe all the invisible activity. As the dish soap becomes evenly mixed with the milk, the action slows down and eventually stops. This is why milk with a higher fat content produces a better explosion of colour. There’s just more fat to combine with all of those dish soap molecules. I enjoyed watching the colours drift away from the milk. It just looks so satisfying to watch. I found it easy to make the experiment. It is so cool that you can make a really cool experiment with things that you can find in the kitchen. I found it hard to try not to make the milk and food colouring mix. When it mixed it only made a small circle of white instead of the whole bowl.

If you would like to make this on your own you will only need a few things.

Milk (Full fat is best)

Food colouring (Different colours for the best results

Any kind of liquid soap will do (Dish soap, Hand soap)
