Step 5) Place 3 drops of food coloring in both beakers at the same time. Record the amount of time it takes for the food coloring to spread through the water in each beaker. Step 6) Rinse both beakers. Repeat steps 1- 6 two times

Next > Inquiry: What is the difference between solids, liquids and gases? Journal Entry (in your binder): 1)Observe what happens to the water as it is heated. List at least 3 qualitative observations. 2)Are we adding or subtracting energy from the water by heating it?

Next > Inquiry: What is the difference between solids, liquids and gases? All matter possesses a certain amount of energy because atoms/molecules are always moving. SolidLiquid Gas Temperature measures the amount of motion/energy, and heat in an object. (measured in Celsius ( o C), Fahrenheit ( o F), or Kelvin

Next > Inquiry: What is the difference between solids, liquids and gases? Matter: anything that takes up space. (made up of atoms/molecules) SolidLiquid Gas States of Matter: different phase of matter based on the amount of energy the atoms have.

Solids Atoms movement and energy: atoms/molecules in a solid do not move a lot. (vibrate). Low energy Next > Shape-shifting ability: solids keep the same shape no matter what container they are in. Volume: solids take up the same amount of space no matter what container they are in.

Liquids (intermediate stage between solids and gases) Atoms movement and energy: Atoms/molecules in a liquid move around more freely than in a solid. (Medium energy) Next > Shape-shifting ability: change shape based on the container it is in Volume: Liquids take up the same amount of space no matter what container they are in.

Gases Next > Shape-shifting ability: change shape based on the container it is in Volume: Gas can be compressed to change the amount of space they take up. (no set volume) Atoms movement and energy: Atoms/molecules in a gas move around quickly. (High energy)

Gases The volume of a gas is affected by both temperature and pressure. Next > 0° C 100° C At higher temperatures, the particles in a gas have more energy, so they move around more rapidly. This causes the gas to occupy more space at higher temperatures than at lower temperatures.

Inquiry: What happens to the temperature of a substance during a phase change? Phase Change: a physical change, when a substance changes its state of matter. Ex. At boiling point, a phase change occurs from liquid to gas. The temperature at which water becomes a gas (steam) is 100° C or 212 o F. Boiling points of other liquids may be much higher or lower than this. Next > *Copy notes in your binder* (3 mins)

Inquiry: What happens to the temperature of a substance during a phase change? The melting point of a substance is one of its most important properties. This is the temperature at which a substance turns from a solid into a liquid. The melting point of ice is above 0° C or 32 o F. This means that water is a liquid at room temperature (20° C). Next >
