Synthetic VS. Natural

What are synthetic materials?

Synthetic material is made by humans, such as plastic and other raw material that are man-made.

Give 2 examples of synthetic materials.

Plastic bottle and plastic toy


What are natural resources?

Natural resources are the material that was from natural, often are animal and planet.

Give 2 examples of natural resources.

Wood and DNA



Polymers and Where They Come From

What is a polymer?

Polymer is made of many molecules that form a really long chains structure.


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

Synthetic Polymer #1

Plastic bottle

What natural resources does this come from?


What would we use this synthetic material for?

To contain water or other liquid.

Synthetic Polymer #2

Non-stick pan

What natural resources does this come from?


What would we use this synthetic material for?

To cook the meal.


 Chemical Reactions

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

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

Plastic, for example, plastic is an organic polymer. Most of the plastic container the carbon atoms, oxygen atoms and nitrogen atoms, which mostly are formed from the monomer. And monomer creates a polymerization of all the atom and create the raw material of plastic.

What is a monomer?

The monomer is a molecule that can combine with another molecule that can be either the same or different to create a polymerization.

What is polymerization?

Polymerization is a process of reacting monomer molecule together in a chemical reaction.

Our Goal:

The goal of our polymer project is to make a polymer which absorbs the impact of any hits such as hammer swings, punches and other. The material is also extremely flexible and soft so it could also be used as a proof material.

Target Market Audience

Some Examples:


Parents with small kids





Teachers/Businessmen/Shop Owners

Pet Owners












Target Market Audience










How will this help them?

Target Market Audience #1:


Parents with small kids.


This polymer can be a stress release product and it could be used to protect the kid.
Possible Target Market Audience #2:

*just in case you have more than one target market audience

Teens. It can help decrease the stress of teens because they often have puberty issue; which our product could decrease their stress.

 Describing Our Polymer

We want the Physical Properties to include:

  • Soft
  • Stretchy
  • Colorful
  • Tenacity

 Polymer Characteristics We Are Looking For

*Gloop, Super Slime, Stretch-elastic Slime, Oobleck

Polymer Characteristics Why this is important
Gloop Gloop is a very slimy product and it’s very bouncy. It can be hag longer which means it’s very stretchy. We want our product to be very stretchy and soft, which gloop fit to our physical properties of the product.
Super Slime Super Slime is also very slimy and sticky, but it is more like a liquid form. Super slime might help us to put gloop and oobleck together to form our product since it’s very sticky.
Oobleck It is a solid form, but when you put pressure on it, it will be liquefied and get back to solid again. Oobleck has been tenacity because if we put pressure on it, it will get back to the original form again.

Our Plan to Develop our Prototype

*Prototype = sample or model

1st we will…                                                   

Look at the polymer we make and their characteristics.

2nd we will…

Present our idea by creating a video.

3rd we will…

Starting to make the polymer.


We will test the polymer to see if it works or not. If it’s not we will retest it.

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
Impact We want our product to absorbed hits, such as hammer swing. Which impact method would help to know if it achieved our goal of absorbed hits.
Stretch We also want our product to be a stress base, and to make our product very stretchy, the stretch method would help us to test if our product is stretchy enough that it would break apart.
Stick Our product is also design for the family that has children, to protect them from hitting their head on a desk corner, and stick method would make sure it would be stable for a really long time.

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.


  • 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.
  • Group video is also linked to post
  • Your blog post demonstrated a sound ability to meet the publishing standards for a blog post, including a clear title with “Polymer Journal #”, a category of “Science,” and tags

Prototype Observations

Prototype Observations Strengths for this Prototype Limitations for this Prototype
Gloop 2.0 The gloop 2.0 is too sticky and not durable enough. To improve this, we gonna add less glue and keep the same amount of borax and water in it and we might add cornstarch. No strength for this prototype. Too sticky and not durable enough, which does not fit the category we want our product to be.
Gloop 2.1 The gloop 2.1 is more like liquid form because we add too much water and less glue; which is not solid and it’s extremely sticky. To improve we should change our strategy and starting testing with more and more materials. It’s not sticky anymore. It’s mostly liquid form, but we want our product to be solid form.
Gloop 2.2 The gloop 2.2 is a pretty successful product, we want our product to be a stress base, and it finally works. Gloop 2.2 is not very sticky, and it’s not liquid form; it’s soft and very bouncy. Even though gloop 2.2 fit our idea on the product, but it’s very easy to break. To improve, we could make it stretcher and probably change the color. It’s durable and it’s not sticky, it’s very bouncy and it’s very soft. It’s not stretch enough, which we want our product to be a stress release base.


Prototype Claim

Use evidence from above observations to complete.

Base on the three prototypes we create, gloop 2.0 and gloop 2.1 is a total failure. Gloop 2.0 is very sticky, it’s not stretchy and durable. Gloop 2.1 is a liquid form because we add too much water; even though it’s not sticky, and it’s better to compare to gloop 2.0. But still, gloop 2.1 is a total failure. Prototype # 3, called Gloop 2.2, was most effective for meeting our goal because It’s very durable, it is extremely soft, it’s very bouncy and it’s colorful, even though it’s not stretch enough; but it meets most of our standard: Soft, tenacity and colorful. So prototype 3 is the most success.


Method of Final Design

Give a summary of how your final product will be made.

We want our product to be stretchy, soft and not sticky. So we have to add a balanced amount of water, borax, and glue to make sure it fit our category.

Make sure you list the steps and amounts used.

  1. Start with the gloop recipe.
  2. Then add 7ml of water and 10ml of borax into the plastic cup.
  3. Followed by step two, add 2cm of glue and one drop of hand lotion.
  4. Finally, mix it with scoop and it will become the final product.


What was the process like?  What was challenging?  What was interesting?  What did I learn?

During the process, it’s starting to become solid form when we add water and borax together; and when we add glue to it, is starting to get sticky.

The challenging part is we are unsure about our formula, so if we too much or too less material it might affect our product.

The interesting part is our product worked even though we don’t know the formula.

I learned how to make a gloop and where gloop product came from, I also understand the chemical formula and how to sell the product like ours.
