Carbon dioxide and water are NOT on the periodic table.  this is because they are ------- not elements

compounds

Length of pencil in cm (I will give you the pencil)

18 cm

Mr. Howe will describe a smart pill experiment.  What is the independent variable in this experiment?

Pill type (smart pill or none)

200

"heat transfer is really neat, it always goes from --- to ---

hot to cold

200

see the board:

A is pointing at what?

amplitude of the wave (height)

400

An element that has similar properties to Sodium (Na) is

Potassium (K) or anything underneath it

400

Look at board--if the field of view diameter is 3 mm, how large is the cell in this field of view?

1mm (3 fit across the field of view so 3mm/3=1mm

400

make a hypothesis about this smart pill experiment

I predict that.......will.......

400

solid substances transferring heat to other solid substances

conduction

400

B is pointing at what

the wavelength

600

columns on the periodic table are called

groups

600

2 mistakes with the graph on the board

inconsistent scale on y-axis

y-axis not labeled

origin not labeled on either axis

600

2 things that should have remained constant in the smart pill experiment


DAILY DOUBLE!!!!!!!!!!!!!!!

age, ability level, same test, same time of day, same amount of sleep and health, etc.

600

heat transfer in a liquid or in the atmosphere

convection

600

We see ourselves in a mirror because of what property of light?

reflection

800

smallest particle of an element is called:

All matter in the universe made of these

atoms

800

Which variable goes on which axis

independent on x-axis

dependent on y-axis

800

Dependent variable in the smart pill experiment

test scores

800
A metal rod that is heated becomes slightly larger.  Why does this happen

The particles in the metal move faster and move further apart

800

A pencil put in a cup of water appears to bend when you look through the cup.  Which property of light is this?

refraction

1000

2 or more substances combined physically together, but not making a chemical reaction.  For example, salt water.

mixture

1000

Make a scale for this data  and graph it (line graph)

Days:             Height:

1                  20 cm

2                  40 cm

3                  50 cm

4                  60 cm

5                  100 cm

draw on board

1000

Group that did get the pill is called the experimental group.  Group that didn't get the pill is called----

the control group

1000

"The average kinetic energy of a substance" is better known as what

temperature

1000

The amount of waves that pass through a fixed space at one time is called

frequency
