ICe SCiEnTIfiC RePoRt

 Wondering:

I know that salt eats away at ice, I wonder if any other powder substance can do the same.

Hypothesis:

I think that salt will be the quickest powder to melt the ice, and the sand will melt the ice the slowest.

Materials:

Salt, baking soda, citric acid, sand, sugar, containers, ice, measuring spoons, flat surface, timer,measuring cup, ¼ of a cup.

Variables:

Independent:

Powders, 

Dependent:

Salt is coming in last. The baking soda has sped up its process, the sugar is going really fast.

Control:

The amount of ice, amount of powder, same temperature, same size ice cubes, 

Procedure:

Pour ½ of water into separate bowls and put it into the freezer overnight.

Pour ¼ of a cup of each powder into a separate bowl/container each.

Pour your powders at the same time into their own container .

Shake the powders and shimmy them all around the ice so it is a faster process.

Start timing the ice straight away when the powders are on the ice.

Results/Observations:

The salt, baking soda, citric acid has sunk into the ice eating it quickly.

Sugar looks like it is melting the ice but the salt looks like it is absorbing the ice.

Sand is coming in last and isn’t really doing anything.

The sugar is melting the ice and not absorbing it but it is melting the ice making the sugar in the lead.

The citric acid looks like it has frozen with the ice.

There are air bubbles and spikes on the citric acid.

The sugar has gotten into the ice and has made a platform.

The sand is absorbing the ice water and it is getting wet.

The salt has made clumps and the access salt has sunk to the bottom.

The citric acid is the coldest.

The salt took 1 hour, 14 minutes and 36 seconds to melt the ice cube and was the fastest.

Conclusion:

The experiment helped my hypothesis and my hypothesis is true. The salt makes a lower power of the ice melting, when the salt is in contact with the ice it interferes with the little bits of the ice cube. The salt then mixes with the water melted off the ice cube and speeds up the process of melting the ice cube. If this were to be in a real life situation let's say that it was a slippery road or stairs on the concrete we could put salt in the ice to melt it.

Rocket Class Presentation

 Hello everyone and in today's blog post I am going to be showing you my slide show of my groups idea about out rocket we have been creating these past 5 weeks and we had to talk about our fins, nose cone, weight, water, psi, and our flight success. It was TERRIBLE at the end because my partners had me talk in front of the WHOLE class. I did the slide by myself as well, anyways it was one of the best feelings of my life when I finished presenting it was ASTONISHING! So I hope you like it and have a nice rest of your day! BYE!!!

Samoan learning

Talofa bloggers,

Since the start of the year we have been learning Samoan.  This is my virtual classroom where I have put all my learning for you to also learn from.  If you hover over items in my classroom, a hyperlink will pop up for you to click on.

In my classroom you will learn about:

Samoa as a country

Link to a traditional dance video

Basic greetings

The alphabet

How to count 1-10 

Information about Siapo - how it is created, some examples

An animation showing a simple conversation in Samoan

I hope you enjoy my classroom and I would really like to know what you enjoyed the most.

Tofa!

Carbonated Drinks vs Mentos!!!!

Hello everyone and in today's blog post I am going to be showing you my slide show showing you what I have been doing for this last weeks and this weeks literacy. My task today was I had to create a conclusion that had something to do with the experiment my class had done a few days ago! I really liked doing this because when I was done putting my information in I got to decorate my slide and post it for you guys to see! I hope you like it and have a good day!!

                        

Part 2 of Ice Melting Experiment

Hello everyone and in today's blog post I am going to be showing you my screencastify of what I have added to my slide about the Ice melting experiment.

My task today was to, because I wasn't at school on tuesday, I had to make a screencastufy of my work and post it on my blog for all of you to see.

I really enjoyed doing this and playing around at the start was very funny until I wanted to really do it to post it. I hope you like it and I will see you later BYE!!!
