Atoms
The part of an atom that is positively charged.
What is a proton?
This is the name for when ANY two atoms come together
What is a molecule?
How well a material resists being scratched or dented
What is hardness?
How tightly matter is packed into an object.
What is density?
The first step of the Engineering Design Process
What is ask; What question are you trying to answer?
The part of an atom that is negatively charged.
This is made when atoms of two DIFFERENT elements come together
What is a compound?
Feature of an object that you can see, touch, hear, or smell
What is a physical property?
If something is THIS it will sink.
What is MORE dense?
The second step of the Engineering Design Process
What is imagine; what are some possible answers or solutions?
The part of the atom that is neutrally charged.
What is a neutron?
This is a pure substance made of the SAME kind of atoms.
What is an element?
How well matter can dissolve into a liquid
What is solubility?
If something is THIS it will float.
What is LESS dense?
The third step of the Engineering Design Process
What is plan; Conduct research, draw a conclusion, make a materials list.
The center of an atom, containing protons and neutrons
What is the nucleus?
H2O, or water, is a type of THIS
What is a compound OR molecule? (Yes, I need both)
A material's ability to bounce light off of its surface
What is reflection?
Rocks and marbles are (more/less) dense than water.
What is more dense?
The fourth step of the Engineering Design Process
What is create; make a prototype and test it out
The name for the number of protons in an atom. Also the number of electrons (since they are the same). It tells what kind of element something is!
What is the Atomic Number?
Au, or gold, is a type of THIS
What is an element?
How easily heat/temperature passes thorugh a material
What is conductivity?
What is put it in water?
The fifth step of the Engineering Design Process
What is improve; What worked? What didn't work?
