1.What happens to the molecules of liquid water when it boils? Have you ever boiled water before? If so, what for? How would you describe the energy of the water before boiling and after boiling?
2. Explain the difference between boiling and evaporation. How are boiling and evaporation similar?
3. What is the boiling point of water in Fahrenheit (°F) and Celsius (°C)?
4. What is the melting point of rock? What is the melting point of water?
5. What happens to water molecules when they freeze into a solid? Have you ever witnessed water changing from a liquid to a solid? How would you describe the energy of the water before and after it froze?
6. At the 2:00 mark, estimate the volume of the liquid in the beaker, don’t forget units!

1. If something is able to float we say that it is _______.
2. How is it possible for a very heavy cruise ship to float?
1. Write a brief summary of Archimedes' Principle.
Super Fun Investigation!!!
Make a density tower!!! Watch the videos below and make your own to explore the concept of density.
Take a picture of it, write down your observations and inferences, and you get two science article passes!!
Watch the videos on density then answer the following questions.
1) Describe density in your own words. Make up your own definition of density. 2) Compare/Contrast the molecules in an object that is very dense with the molecules in an object that has a low density. Draw a picture of the two objects and their molecules. 3) mass = 4.4 g volume = 2.2 mL density = ? 4) An object has mass of 450 g and a volume of 150 cm3, calculate its density. 5) a. Watch the video on measuring matter. https://www.brainpop.com/science/matterandchemistry/measuringmatter/ b. Take the review quiz to assess your knowledge. https://www.brainpop.com/science/matterandchemistry/measuringmatter/quiz/
Density = Mass/Volume
Mass is the measure of matter. Everything has mass. The bigger of the object, the more mass it has.
We measure the mass of an object with a triple beam balance.
Volume is the amount of space occupied by an object measured in three dimensions, expressed in cubic units.
The volume of an object can be measured with a graduated cylinder.
Density is a measure of how much mass is contained in a given unit volume (density = mass/volume). It is usually expressed in kg/m^3. Put simply, if mass is a measure of how much 'stuff' there is in an object, density is a measure of how tightly that 'stuff' is packed together.

LAB #4 – Simple Machines Help Us (620)
Problem: What are the motions that each simple machine makes in order to make work easier?
Hypothesis: I predict that simple machines make work easier.... How?
Materials: various simple and compound machines
Results:
Name of the object
Purpose of the object
What kind of simple machine/s is it?
Draw a picture of the object
1. Plastic drink top
2. chemistry tongs (2)
3. cabinet drawer track
4. scissors (2)
5. soup spoon (2)
6. blinds
7. spray bottle (2)
8. microscope (3)
9. alligator clips (2)
10. flashlight
Analysis:
1) How do simple machines make our lives easier?
2) Pick three of the objects from the lab and explain how it would be like without them? How would you accomplish the tasks they help us with without them?
3) Go to your data table and label the fulcrum for each of your levers.
4) Find three simple machines at home and add them to your Results. 5) a. Sketch a picture of each simple machine; use arrows to show the motion of each. b. How does each simple machine change the direction, distance, or magnitude of a force?
Conclusion
