What Do You Recall?

Physical Science

Station 1 investigating forces

Station 1 --Investigating Forces

Do you know your forces? ANSWERS

1--D- Magnetism: The iron filings move around in the containers (with the magnet) due to magnetic force. This is a NON contact force, meaning magnetism is a force that can act at a distance.

2--A-Friction (or really, drag). The filings move slower through the water due to friction (drag), but are still attracted to the magnet.

What do you recall

3--C-Electric Force (static electricity). When the balloons are charged (electrons are stolen!), they are unbalanced, so they seek protons and are attracted to other objects.

4--A-Friction is the only contact force between friction, gravity, electric, and magnetic.

5--A-The magnetic force was greater than gravity because the filings stopped traveling downward with gravity and were attracted by the magnet.

1 what forces are involved in making a hot air balloon move

1- What forces are involved in making a hot air balloon move?

What do you recall

2 - What happens when the forces acting on the balloon are balanced?

What happens when they are unbalanced?

Station 2 observing motion

Station 2--Observing Motion

Forces with causes:

Lift = (D) Hot air balloon;

Weight = (C) Gravity (F= MxA);

Thrust = (B) Push with finger, though this is a stretch… thrust would be rocket fuel boosters or engine propelling you forward, or air moving out of a balloon, propelling you forward (Newton’s 3rd law). Push with finger is more APPLIED;

Drag = (A) Friction

What do you recall

1--When the glider is hovering (but not moving), what forces are balanced? C-Thrust and Drag AND Lift and Weight. No movement = Balanced. Constant motion is also balanced--INERTIA!!! 1st Law!!! An object in motion stays in motion, an object at rest stays at rest (at same speed in same direction (velocity) unless acted upon by an unbalanced force!

2--What must happen to begin movement? ...needs thrust to initiate (and counter drag). **

What do you recall

3--Now that it’s moving, what will happen when all the forces are balanced? A--It will continue doing what it was...Inertia.

4--When 2 gliders collide-- B-Net force is determined by subtracting.

4 N 2 N Net force = 2 N

What do you recall

Describe the glider’s speed over time (note the axis labels!!!).

* Speed is constant until 4 seconds--slope the same. Then the glider slows (flatter slope), then it stops. No change in distance over time.

Station 7 matter matters

Station 7 Matter Matters

1--Protons are the identity! 9 protons = F

2--Add a proton? Protons are the identity! = Ne

3--Neutrons do not affect the element! Varying numbers of neutrons mean the atoms are ISOTOPES. = Still Ne

4--Electrons are EXTREMELY small.

5--Families (columns) on the periodic table share similar properties!

8--Liquid to gas is vaporization (evaporation). Condensation is gas to liquid, deposition is gas to solid, and sublimation is solid to gas.

10 --The solar powered race car

*Nicholas, where is my car?? ;)

How should a scientist confirm that an experiment has good (valid and reliable) data?

1. Malik and Anthony were testing TWO variables….they had TWO test variables in ONE experiment. --Width and size (C). This INDEPENDENT (TEST) Variable was the variable that the experimenters changed ON PURPOSE, BUT changing TWO variables makes this experiment NOT valid in the first place.

2. The intended DEPENDANT Variable was the speed of the car (D), as it relied on the tire size (and width unfortunately).

3. The constant was the SAME material for the tires attached the same way. Constants are used to be sure that there are no other variables that could affect the results of the experiment.

4 --The force that slowed the motion was friction (c).

10 solar powered car

10--Solar powered car

5--Force created by the solar cell was thrust….the POWER behind the movement.

6--Multiple trials done by the same people is repetition (A).

7--The data shows that the thin big wheels are best (D)--ick. I don’t like this experiment!!

8--The boys who did the experiment and repeated it several times gave it to their friends to do. Their results were similar. This says that the experiment can be REPLICATED (B)! Others do it and get similar results.

**They could improve their experiment by isolating a test variable!

11 what are 3 ways that heat can move from one substance to another

11 What are 3 ways that heat can move from one substance to another?

  • radiation - INITIAL transfer of heat to anything! through anything (vacuum)

  • conduction - transferring heat through solids

  • convection - transferring heat through fluids

  • from areas of higher temp toareas of lower temp.

    (Heat moves cold does not).

  • no such thing as cold onlyvarious amounts of heat

11 heat flows toward cooler objects

11--Heat Flows toward cooler objects.

1--Metal rod heated fastest --conductor!!!

2--Metal rod also cooled the fastest! Conductor (it lost its heat as the heat moves quickly in and out of conductors).

3--Yes! The ice GAINED the heat, hence it melted. Heat moved into the ice, not the cold moving out of the ice. Heat moves! Cold doesn’t!

4--Transfer of heat through rods (conduction)--solids.

5--Steam moving upward (air circulating) --Convection--gases.

What do you recall


Radiation is the initial heat transfer. What they are getting at here is if you held your hand near the plate that was initially transferring the heat, that radiation would warm your hand. If you touched someone’s arm after that, conduction would transfer that heat.

Convection and conduction are secondary transfers of energy….Radiation is the initial transfer. ie., sun warms the swing at the park (radiation). You sit on it...conduction! Ouch!

What do you recall


7 When adding ice, the boiling water transfers its heat to the ice, so the overall temperature drops.

Calculate Density!

20 g/mL = 4 g / x mL? This seemed to stump people. If you are ever not sure how to set up an equation, put in numbers that you can easily solve for and think about how you would solve!

What do you recall



Solvent = means the substance doing the dissolving (the water in salt water).

Solute = the substance being dissolved (salt in salt water).

Saturated means dissolved until no more can dissolve so there is extra! Think Kool-aid sludge at the bottom.

15 What are some similarities and differences in light and sound waves?

Both are forms of energy that move as waves

(characteristics: wavelength, frequency, amplitude)

Sound requires matter to compress
