## Every thing about Desertification(Capstone video project)

Making a video about desertification was the result of 2 month of working. Most important part from survey, research, cornel note and essay were combined i this video. By organising video I learned how to prepare the informations clearly which can give the strong message to audience.

## Experience about using graph in real world

In the math class I has an interesting experience. Which is using the graph in our real life. To hit the target with the catapult we had to insert the values of distant to the function we made. The most challenging part was when the catapult keeps missing the target even we put the correct value. Because of that, we realised that our catapult was little bit broken but we couldn’t fix it because it wasn’t assembly type. From that experience, next time I am going to make a catapult as an assembly type. This project helped me understanding how does principle of functions works in life.Catapult Final

Sorry that I don’t have enough evidences because i missed the class for two weeks.

Design Journal Checklist # 4

Optimising Prototypes

• You describe important observations about each of your prototypes and identify strengths and limitations of each prototype.
• Recommendations for future improvements to your design.
• You make a claim about which prototype was most effective for meeting your goal, and your claim is supported by evidence from your observations.
• You present a clear method for how to make your final design.
• You reflect on the design process and what you have learned.

Communication

• Your writing is clear and concise with few grammar errors
• You use scientific terminology
• You create multimedia that suits the post and presented my information in a way that clearly explained my topic.

 Prototype Observations Strengths for this Prototype Limitations for this Prototype 16ml Borax, 8 ml of water, PVA solution: 5ml, Glue 1cm Doesn’t stick very well, too rubbery, very smooth, too hard at first, doesn’t stretch Bounces 15cm after hitting the table. Strength because of if it is bouncy, it means it’s stiff. This polymer doesn’t stick to furniture so we can’t use it. It doesn’t stretch so when you first want to use it doesn’t fit to the furniture 1 cm of glue, 8ml of PVA, 3ml of borax, 4ml water It was sticky but it didn’t sustain. After few second the polymer dropped down of flow. We decide to put more glue, 4ml more so it could become even stickier, 2ml of borax so the polymer is even flexible There is no flexibility to change its shape consistently, but it hardens in a much more time. However even we added more glues, the stickiness didn’t maintain as long as we wanted so we had to find another polymer which can maintain the stickiness. 15 ml of PVA, 4 ml of water, 5cm of glue, 2ml of borax Sticky and doesn’t fall off, Stiff, Bouncy, Could Change into different shapes Gives you enough amount of time to adjust the size, and could form into different shapes to fit at furniture.  If user accidentally hit a table corner, with this polymer they will be safe. Only problem is that after you opened the pack to use this polymer, in 4 minutes you have to stick polymer at furniture

Prototype Claim

Use evidence from above observations to complete.

Prototype # __2__, called World Best Polymer, was most effective for meeting our goal because: It was the perfect polymer what we were looking for. First, it was sticky enough to stick at furniture. Second, cushioning of polymer is enough to protect people from damage of crushing edge of furniture.

Method of Final Design

Make sure you list the steps and amounts used.

15 ml of PVA, 4 ml of water, 5cm of glue, 2ml of borax

1. Pour 5cm of glue and 4ml of water into the beaker.
2. Add 15ml of PVA and 2ml of Borax.
3. Add 2 drops of blue food colouring.
4. Mix the ingredients with a wooden stick.
5. Put it in your hands as you see the mixture of monomers making a polymer becoming a solid and add more 0.5cm of glue if there is no solid formed.
6. Add one or two drops of glue if it is stringy and pour one or two drops of Borax if it sticks in your hand.

Describing Our Polymer

1. We are making… Polymer which can stick to edge furniture and protect us getting injured by edge

1. We want the Physical Properties to include:
• Soft
• Cushioning
• Sticky

Our Plan to Develop our Prototype

*Prototype = sample or model

1st we will…                                                     2nd we will…

 Try to make outside of polymer unstick by using solutions.
 Make it stickier that it will stick to furniture and stay stocked.

 Try to maintain stickiness by adding materials.

 Mixed food color to make more beautiful color.

Our Method for Testing our Prototype: How we’ll test it to see if it works

 Method Why we chose this/How this will be effective Check the time how long the polymer can be stocked at furniture. This can check the durability of stickiness. Check the polymer by bumping. Check if it hurts or not. Check the cushioning. It have to be enough soft to protect us from edge of furniture.

Our Specific Goal:

The goal of our polymer project is to …

Target Market Audience

 Some Examples: Adults Parents with small kids Elderly Kids Teens Boys/Girls Teachers/Businessmen/Shop Owners Pet Owners Travelers Target Market Audience How will this help them? Target Market Audience #1: Adults, parent with small kids To fix their furniture or add design to make furniture looks better.

Using Observations of Base Polymers

*Gloop, Super Slime, Boogers, Oobleck, Goobers

 Polymer Characteristics We Like for Our Polymer Why this is important Gloop Sticky Our polymer should stuck at furniture Super Slime Isn’t sticky after few minutes After we stuck our polymer at furniture it should not be sticky Boogers None Oobleck None Goobers None

## Science journal 1

Journal #1

Synthetic VS. Natural

 What are synthetic materials? Something made of artificial material, not natural items.   Give 2 examples of synthetic materials. Plastic electronics, nylon What are natural resources? It is resources which exist without actions of humankind.   Give 2 examples of natural resources. DNA, Silk

Polymers and Where They Come From

What is a polymer?

It is a large molecule, or macromolecule, composed of many repeated subunits

Give 2 examples of synthetic polymers and the natural resources they come from

 Synthetic Polymer #1 Polyethylene What natural resources does this come from? Natural gas What would we use this synthetic material for? Plastic bags Synthetic Polymer #2 Nylon What natural resources does this come from?   They used chemicals.   Amine, hexmethylene diamine and adipic acid. What would we use this synthetic material for? Stockings.

Chemical Reactions

How do natural resources go through a chemical reaction to become synthetic materials?

*important words to think about…polymerization, monomer, polymer

The monomer of natural resources goes through polymerization. Monomer in the natural resources turn to bigger molecule and form a polymer.

What is a monomer?

A molecule that can be bonded to other identical molecules to form a polymer. So, it is a sort of material to form a polymer.

What is polymerization?

A chemical reaction in which two or more small molecules combine to form larger molecules that contain repeating structural units of the original molecules. It is a process of forming larger molecules.

## Revolutionary Voices Journal

This journal shows the start of the Syrian Civil War. The main character is the middle of the event and it shows the boys decisions during the revolution. If you read the journal you will understand the sequence of revolution to cilvil war. I wanted to show a sequence of Cilvil War in one boys site who was rebel army and White Helmets.
