1 FOSS Journal (Name) 2

2 Rubric - 40 pts. You are graded on your FOSS journaling. You are expected to complete all notes, even if you are absent. Please check with classmates to see if you can copy notes. Yes, I WANT YOU TO COPY THESE! Please keep the rubric stapled/taped to the back cover.

3 ABCD s of Scientific Drawing A = Accurate B = BIG C = Colorful D = Detailed

4 What should my notes look like? Heading Types of Energy 12/04/12 FQ: 1)What is energy? 2) How many types of energy do you think we have? P: Energy is I think that there are Highlighting the same color the whole time. kinetic energy the energy of an object when it is in motion potential energy the energy an object has because of where it is or how it s made Date Forms of Energy: Gravitational Potential Energy (gravity) Electrical Energy (electricity) Elastic Potential Energy (stored/compressed) Chemical Energy (stored energy) Mechanical Energy (movement) C: Energy is Organized/Neat Pipe to main refinery. ABCD s Page # pg.1 Page # pg.2

5 Table of Contents Inv. 1-1 Investigating Magnets and Materials page 1-2

6 Inv. 1-1 Investigating Magnets & Materials DATE FQ: 1) What kind of materials do magnets stick to? 2) What happens when you bring two or more magnets together? P: (IN PEN)

Craft sticks paper fastener cardboard yarn/string shiny nail dull nail

7 Test objects Objects that stick Objects that DON T stick black rock brass ring river pebbles paper clip plastic chip Aluminum foil screw soda straw Craft sticks paper fastener cardboard yarn/string shiny nail dull nail copper sheet washer screen sponge rubber band Magnets only stick to iron or steel.

8 Iron or steel objects? Things made of iron or steel legs of desks stapler air vent hooks with screws door beams in the walls walls Things that are NOT iron or steel cubbies stool top of desk chair pencil hook of pen sink

9 force a push or pull magnet an object that sticks to iron or steel magnetism a specific kind of force attract when magnets pull together repel when magnets push apart

10 C: Magnets stick to iron or steel. Two magnets can attract or repel. A force is a push or pull.

12 DATE Inv. 1-2 Investigating More Magnetic Properties FQ: 1) How do magnets interact with other objects? 2) Does an iron object have to touch a magnet to become a temporary magnet? 3) Does magnetic force go through all materials? P: (IN PEN)

13 Temporary magnet Magnet touching nail. Nail is a temporary magnet. Magnetic force can go through the cardboard. Magnet not touching.

14 temporary magnet a piece of iron that behaves like a magnet when it is touching a permanent magnet induced magnetism the influence of a permanent magnet s magnetic field on a piece of iron, which makes the iron act like a magnet

15 C: Magnetism can be induced only in iron or steel. The magnetic force acts through space and most materials. The magnetic force of attraction between two magnets decreases with distance.

17 Inv. 1-3 Breaking the Force DATE FQ: How can we measure the force of attraction between two magnets? P: (IN PEN)

18 graph organizes data visually to show relationship between two things prediction an educated guess based on data or previous experience intersection the point at which two lines cross

19 Number of Spacers Number of Washers 0 P: A: 1 P: A: * SKIP* 2 P: A: 3 P: A: 4 P: A: 5 P: A: 6 P: A: spacers washers magnets balance

20 Number of Washers The Force Line graph spacers 1 spacer 2 spacers 3 spacers 4 spacers 5 spacers 6 spacers Number of Spacers

21 C: The greater the distance between two magnets, the weaker the force of attraction.

22 Table of Contents Inv. 1-1 Investigating Magnets and Materials page 1-2 Inv. 1-2 Investigating More Magnetic Properties page 3-4 Inv. 1-3 Breaking the Force page 5-6 Inv. 1-4 Detecting the Force of Magnetism page 7-8

23 DATE Inv. 1-4 Detecting the Force of Magnetism FQ: Without looking, can you figure out where two magnets are taped in a box? P: (IN PEN)

24 detector something you use to gather evidence about something you can t see C: Compasses, iron fillings, and iron objects can be used to detect a magnetic field.

25 Key = magnet located here = compass pointing toward magnet Box # 3 Box # 1 I was able to locate the mystery magnets by using compasses and paperclips. Box # 1 was difficult because my compass pointed to both magnets and I didn t realize it. I needed to use paperclips to find out that magnets were next to each other.
