The effect of the change (caused by the IV).  What are you measuring at the end of the experiment? 

DV (Dependent Variable)

300

When many water molecules on the surface of water pull on one another this is created.   An example is when you see a bug floating on top of the surface.


Surface Tension

400

An educated guess; written as an ‘If…, then…’ statement

hypothesis

400

What does it mean when water is polar?

Oen end is positive and one is negative, so it is a sticky molecule.

We have seasons because __ and ___

tilt and revolution

400

Which is more dense warm or cold air and explain your reasoning.

Cold air is more dense.  When temperature decreases the molecules get closer together.

Give an example of radiation, conduction and convection

  • Radiation Example: The Sun’s heat radiates to Earth, warming our air, soil, and water.

  • Conduction  Example:  Touching hot sand with your feet.

  • Convection:  Example:  Water boiling, wind currents, ocean currents, and hot air balloon.
