States of Matter
What are the states of matter?
solid, liquid, gas, plasma
What is matter? give an example
EVERYTHING that takes up space
How many steps are in the engineer design process?
6 steps
A person who uses his/her creativity and understanding of materials, tools, and science to design things that solve problems?
Engineers!
How are the atoms formed in a solid? (draw a picture)
Tightly together
Give an example of a property of matter
Size, shape, color, texture
What part of the process am I doing?
- to make it less sticky, add flour
- to make it less thick, add water
Improve!
The engineer design process
How are the molecules formed in a gas? (Draw a picture)
All over the place
When water turns into ice, what is happening to the water?
freezing/ going from a liquid to solid
What is another example of a process that we talked about? (it can be at home)
A Recipe
what was the name of the engineer who made playdough in the book we read together?
Michelle
What state of matter can be changed with thermal energy?
Solid-> liquid
how is a chemical change different than a physical change?
chemical change- new state of matter
physical change-same state of matter just different form
Does the order of a process matter? Why?
Yes, because it needs to be done in order to get the correct product outcome
Write down one example of what an engineer does
creates stuff, improves models, tests tires
What does our 4th state of matter give off?
Light energy
Write whether it is a physical change or chemical change.
1. physical
2. chemical
3. chemical
4. physical
Give one example of how you could improve the process of making play dough
Add flour: too sticky
Add water: too thick
Add salt: too smooth
What type of engineering did we do when we made playdough?
Chemical Engineering
