Base unit: meter (m)

​

1 inch = 2.54 centimeters

100 centimeters = 1 m​

1000 m = 1 kilometer (km)

A 5K race (5 km) = ​3.1 miles

​I live about 25 miles away. That is about 40 km.

​Distance in metric units

Multiple Choice

Which metric units should I use to describe a distance of 20 miles?

• kilometer (km)

• meter (m)

• centimeter (cm)

When we add heat energy to matter, its molecules move more and it can change phase.

​

Soli​ds have the least energy in its molecules. As more energy is added, solids can melt to liquids, vaporize into gas, and ionize into plasma.

Multiple Choice

The molecules of a gas have a lot of energy and movement. Which state of matter has LESS energy in its molecules than a gas?

• Solid

• Plasma

​Protons and neutrons are in the nucleus (middle) of the atom.

​

Electrons are in orbitals (shells, energy levels) outside the nucleus.​

We draw the orbitals as circles.

Multiple Choice

In what part of the atom are the protons and neutrons?

• Nucleus

• Orbitals

​The Periodic Table of the Elements is arranged by the number of protons in the atoms of that element.

​(Number of protons)

Multiple Choice

How is the modern periodic table arranged?

• Increasing atomic number

• By ions and isotopes

• Decreasing atomic mass

​Elements in the same GROUP (up/down column) have similar PROPERTIES because they have the same number of valence (outer) ELECTRONS.

Multiple Choice

What do elements in the same group of the periodic table have in common?

• They have the same number of valence electrons and have similar properties.

• They start with the same letter and have the same number of protons.

​The pH scale describes how acidic or alkaline (basic) a solution is. Water is neutral at pH=7. Acids have pH < 7. Bases have pH > 7.

Multiple Choice

What is the pH of distilled (purified) water?

• Neutral pH = 7

• Acid pH < 7

• Base pH > 7

​The colors of the visible light spectrum are "ROY G BIV":

red, orange, yellow, green, blue, indigo, and violet​

Multiple Choice

Which color is NOT named in the traditional set of colors of the visible light spectrum?

• Pink

• Indigo
