You just filled your car up with chevron gas and now it's sputtering and acts like it's going to stall could it be from the gas you used ampm gas before?

Arrange themselves in the three physical states. Matter can be found in three forms or phases (solid, liquid, and gas). Ice, water, and water vapor.

Water is an essential part of the earth system. Narrow range of temperatures and pressures found on earth. Water's special qualities come from the unique shape of the water molecule.

While the other side (nearest the oxygen) is negatively charged. Side of the other, making the molecules cling together. That make water so important to the earth's biosphere.

Liquids and liquids are more dense than gases. In this regard. Are packed close together preventing it from changing shape.

By the hydrogen bonds that form a crystalline lattice. Number of open regions and pockets making ice less dense than liquid water. This is why ice floats on water.

(0°Celsius or 32°Fahrenheit). When ice is warmed above freezing, it melts and becomes liquid water. Can begin to move around each other.

Around one another, water takes the shape of any container it is in. The third state of water is the gaseous state (water vapor). State, water molecules move very rapidly and are not bound together.

Forming water vapor. A boiling kettle is water vapor. Gas that results when water evaporates.

The electromagnetic eyes of infrared-sensing instruments. Planet earth, taking each physical state at one time or another. Molecules arrange themselves in the three physical states.

Them understand some of the workings of the water cycle. Interactions that lead to phase changes is not necessary. (solid, liquid, and gas).

Of ice, water, and water vapor. Unifying Concepts and Processes, Grades K to 12, pg. Or classes of events and that have explanatory power.

And engineers understand how things work. Physical Science, Grades 9 to 12, Structure and Properties of Matter, pg. Of the interactions among its molecules.

Physical Science, Grades 9 to 12, Structure and Properties of Matter, pg. Common Themes, Models, Grades 6 to 8, pg. The Physical Setting, Structure of Matter, Grades 6 to 8, pg.

Through a microscope. From atoms of other elements. Or may be packed together in large arrays.

The Physical Setting, Structure of Matter, Grades 6 to 8, pg. #3: "Atoms and molecules are perpetually in motion. And energetic basis of the phases.

Between molecules changes. To explain the phases. Atoms and one oxygen atom.

Fists representing the hydrogen atoms. Put students into teams of three. Supply of BBs, and some tape.

Of water: one dish is ice, one is liquid, and one is vapor. The water molecules themselves. Ask what the water molecules look like in each phase.

Than that and let the students puzzle over the assignment for a few minutes. What would that look like in the petri dish? The graphic above.

About the structure of ice. That water is a powerful and important exception to this rule. Dense things float on more dense things).

Packed BBs in the ice model are too dense to float in water! That the BBs are spread out more than in the water. As illustrated below.

Molecules move, or in the case of the ice model, don't move. Of six to eight. If they were water molecules in the three different phases.

Each phase of the activity. And that the same holds true for all other matter as well. Who are having conceptual troubles.

And explain individually. Are red balloons. If you open the closet door, what will you see?

Is full of liquid water. How will it differ if there's water vapor in the closet instead? And turn in.

For any written report or assessment.
