1. Chapter 1-3: Tools & Measurement
Technology - the application of science for practical purposes.
-the use of tools, machines, materials, and processes to meet human needs.

2. Compound Light Microscope - an instrument that magnifies small objects so that can be seen easily by using two or more lenses. Electron Microscope - a microscope that focuses a beam of electrons to magnify objects.

3. Area - a measure of the size of a surface or a region
Area - a measure of the size of a surface or a region. Volume - a measure of the size of a body or region in 3-dimensional space. - a measure of something’s size in 3-dimensional space.

4. Mass - a measure of the amount of matter in an object
Mass - a measure of the amount of matter in an object. - the amount of matter in something. Weight - a measure of the gravitational force exerted on an object; - its value can change w/ the location of the object in the universe.

5. Temperature - a measure of how hot (or cold) something is;
specifically, a measure of the average kinetic energy of the particles in an object.
the amount of energy in matter.

6. International System of Units (SI):
- help scientists share and compare their work.
they are based on the number 10
Computer is used to solve a complex mathematical problem.

7. Scanning Electron Microscope – technology used to produce a 3-D image of a tiny living organism.
