1 Friday August 26, 2016 1) What are four things you are not supposed to do during a lab? 2) Should you wear safety goggles when dealing with solid materials? Why?

2 Brain-Pop

3 Water-Works Question to think about: How does temperature affect the speed of an object’s particles?

4 Time to make a foldable!!

5 Monday August 29, 2016 How do the particles of solids compare to the particles in an equal volume of liquid?

6 Finish up your foldable from Friday.

7 Kinetic Theory Gas State The kinetic theory is an explanation of how particles in matter behave. The three assumptions of the kinetic theory are as follows: All matter is composed of small particles (atoms, molecules, or ions). These particles are in constant, random motion. These particles are colliding with each other and the walls of their container. Particles lose some energy during collisions with other particles. But the amount of energy lost is very small and can be neglected in most cases. Matter and Thermal Energy Copyright © McGraw-Hill Education

8 Gas State Gases do not have a fixed volume or shape. Therefore, they can spread far apart or contract to fill the container that they are in. Matter and Thermal Energy Copyright © McGraw-Hill Education

9 Liquid state Particles in the liquid state have less kinetic energy than in the gas state. Thus, the particles in the liquid state are less able to overcome their attractions to each other. The particles cling together, giving liquids a definite volume. The particles can slide past each other, allowing liquids to flow and take the shape of their container.

10 Solid State The particles of a solid are closely packed together. Most solid materials have a specific type of geometric arrangement in which they form when cooled. Matter and Thermal Energy Copyright © McGraw-Hill Education

11 Solid State The type of geometric arrangement formed by a solid is important. Chemical and physical properties of solids often can be attributed to the type of geometric arrangement that the solid forms. Matter and Thermal Energy Copyright © McGraw-Hill Education

12 Plasma State Plasma is matter that has enough energy to overcome not just the attractive forces between its particles but also the attractive forces within its atoms. The forces produced from high-energy collisions are so great that electrons from the atom are stripped off. All of the observed stars including the Sun consist of plasma. Plasma also is found in lightning bolts, neon and fluorescent tubes, and auroras. Matter and Thermal Energy Copyright © McGraw-Hill Education

13 Amorphous Solid

14 Tuesday August 30, 2016 Compare and contrast a gas with plasma.
