actually produced. Given the following formulas, calculate the

percent error of this experimental data.

What is 3.8% error ?

Back Reveal Question

400 The ability of a substance to combine with or change

into one or more other substances. Examples:

400 A 10.0 gram sample of magnesium metal rusted in the

presence of oxygen to form 16.6 grams of magnesium

oxide rust. How many grams of oxygen reacted with the

metal?

What is 6.6 grams of oxygen?

Back Reveal Question

Mixtures of Matter

400 Homogeneous mixtures made by dissolving a solute into

a solvent. Examples: Saltwater or Kool-Aid

What is a chemical solution?

Back Reveal Question

Elements & Compounds

400 The law of definite proportions states that a compound is always

composed of the same elements in the same proportions by

mass, no matter how large or small the sample. Use the formula

to solve the following laboratory scenario: “1.0 grams of hydrogen

reacts completely with 19.0 grams of fluorine. What is the percent

by mass of hydrogen in the compound that is formed?”

What is 5.0% hydrogen by mass?

Back Reveal Question

Atomic Theory

400 The number of protons (p+) in the

nucleus of an atom does not

account for the total mass of that

atom. Chadwick reasoned that a

third particle must exist, which is

massive like protons (p+), but

carries no charge because

magnets and electric fields cannot

influence these particles. Name

that particle.

What is a neutron (𝑛0) ?

Back Reveal Question

Metrics - 500 When data is collected from an

experiment, researches must find

and explain patterns in the data.

Often data is graphed to display

and calculate important

information. Given the following

graphed data from an experiment

and the formula for the slope of a

line, calculate the density of

aluminum (mass/volume).

What is 2.7 𝑔 𝑐𝑚3 ?

Back Reveal Question

Properties of Matter

500 Physical properties are characteristics (traits) of

matter that can be observed or measured without

changing the sample’s composition. Name three

examples of physical properties of a substance.

melting/freezing point, and boiling/condensation point?

sublimation are all methods for _____.

What is separating mixtures into

their ingredients?

Back Reveal Question

Elements &

Compounds - 500 The law of multiple proportions

states that when different

compounds are formed by a

combination of the same elements,

different masses of one element

combine with the same fixed mass

of the other element in a ratio of

small whole numbers. Use the data

and formula to prove that

copper (I) chloride [ 𝐶𝑢𝐶𝑙 ] and

copper (II) chloride [ 𝐶𝑢𝐶𝑙2 ] are

made of the same elements, but are

combined in different whole number

ratios.

What is a 2:1 ratio ?

Back Reveal Question

Atomic Theory - 500 Multiple forms of the same element can

exist, called isotopes. The number of

protons in the nucleus of an atom is what

determines which element the atom is,

along with its physical and chemical

properties. Multiple forms of the same

element can exist because the number of

neutrons in the nucleus can vary.

Calculate the number of neutrons (𝑛0) in

the two isotopes of copper shown.

What are 34 and 36 neutrons (𝑛0) ?

Daily Double Instructions

Main Menu

Set # Teams

Instructions For Adding A Daily Double: 1) Use Word Art to create a nice “Daily Double”.

2) Copy the word art to whichever slide(s) you want the Daily Double to be on. 3) Go to the Animations screen and choose “Custom Animation”.

4) Click the Daily Double Word Art to select it and choose “Add Effect”. There should be a great number of entrances to choose from.

5) Right click on the element that was just added to the Animation list and drag it to the top of the list. Now right click and choose “Start with Previous”. This will cause the graphic to enter when the slide is shown. Now choose “Effect Options”. The second menu box

down should say After Animation. Click the arrow and choose “Hide on Next Mouse Click”. Click Ok.

6) Finally, click on the question (just the question) in the main screen. Go back to the custom animation panel and click Add Effect, then find the effect labeled “Appear”. Now,

when you go to the slide, you should have an appearing Daily Double graphic which disappears and shows the question the next time the mouse is clicked.

P.S. If you want to add a Daily Double sound effect, then when you go into the “Effect Options”

menu to make it disappear after the mouse click, choose a sound to play.

Instructions For Turning On Macros: 1) If you’re using Office 2007, then when the PowerPoint opens, there will be a status bar at

the top of the screen saying macros have been disabled. There is a button that says “Options”. Choose this, and then choose “Enable” and click OK.

2) If you are using earlier versions of Office, then it is a little more complicated: A) On the top menu, choose “Tools”

B) Choose “Security” C) Choose “Macros”

D) You will be given three options (Low, Medium, and High). Choose Medium. E) Click OK, then close PowerPoint completely.

F) Restart the program.

Macros should now be enabled. To check , try running the slideshow and clicking the “Start Game” button. If nothing happens, then feel free to email me at

rmayers@austin.k12.mn.us, and I will try to help you out.
