Are ceramics good or poor conductors of heat and electricity?
Poor conductors.
That being said : A ceramic mug can hold hot coffee without burning your hands.
Some materials are commonly used to make composites.

Different colored bins are used to separate waste.
Choose ONE color bin and explain what type of waste goes in it.
Blue bin 👉 Used for general household trash that cannot be recycled.
Green bin 👉 Used for biodegradable waste such as food scraps and vegetable remains.
Yellow bin 👉 Used for recyclable waste such as plastic containers, paper, glass bottles, and cans.
Red bin 👉 Used for hazardous waste that can be harmful to people and the environment (e.g. batteries, spray cans, light bulbs).
This image represents an example of : homopolymers or copolymers. Explain why.
This image represents a copolymer, because it is made of different colored beads, which represent different types of monomers joined together in the same polymer chain.
Starch, cellulose, and glycogen are examples of:
Natural Polymer
How are ceramics hardened?
By heating at high temperatures.
Fiberglass is a modern composite composed of two types materials, what are they?
Plastic and Glass
People burn plastic trash near homes.
Explain two impacts this could cause (2–3 sentences).
(Expected: air pollution + respiratory problems; harmful chemicals; environment damage.)
A plastic bottle has a higher density than water.
Will it float or sink in water? Explain why.
It will sink, because materials with a higher density than water sink, while materials with a lower density float.
What type of plastic is a water bottle?
Thermoplastic
Ceramic products can be formed by several techniques that vary in materials and equipment.
This image shows one ceramic forming technique. What is the name of this technique?
In slip casting
What is a composite? Give a full sentence explination.
A composite is material made by combining two or more different materials to improve the properties that are stronger than those of individual materials.
Give ONE example of how you apply each of the 3Rs (Reduce, Reuse, Recycle) in your daily life.
Reduce (use less)
Avoid using disposable plates, cups, spoons, and napkins
Bring a reusable water bottle
Use a lunchbox instead of plastic bags
Buy only what you need
Avoid single-use plastics
Reuse (use again)
Use both sides of each paper sheet
Reuse shopping bags
Reuse containers or jars
Pass items to others instead of throwing them away
Reuse bottles or boxes at home
Recycle (turn into new products)
Buy products that can be recycled
Separate recyclable waste
Recycle glass bottles and cans
Recycle plastic containers with recycling symbols
Use stainless steel or recyclable lunch boxes
Metal spoons get hot quickly in soup, but ceramic spoons do not.
Explain why.
Ceramics are poor conductors of heat, so heat does not transfer easily through them.
