Hacking the 8th grade Science STAAR

Watch the video on how to use your periodic table and formula chart to help you be successful on the STAAR. Be sure to answer all questions.

Multiple Choice

What does APE represent?

• The atomic number is the same as the number of protons and electrons.

• Atoms Produce Electricity

• The atomic mass plus the number of protons plus the number of electrons.

• The atomic mass is the same as the number of protons and electrons.

Multiple Choice

The atomic mass is...

• Protons - Neutrons

• Protons + Neutrons

• Protons + Electrons

• Protons - Electrons

Multiple Choice

MAN means

• Atomic Mass - Atomic Number = Neutrons

• Atomic Number + Neutrons = Atomic Mass

• Atomic Mass + Atomic Number + Neutrons

• Atomic Mass is equal to the number of Neutrons

Multiple Choice

Groups are also called Families because.....

• They have the same number of energy levels.

• They are in the same period.

• They have the same number of electrons.

• They have many similarities such as the same number of valence electrons.

Multiple Choice

All of the elements in Group 16 (of Family 16) have what in common?

• These elements are highly reactive.

• These elements have similar properties and similar reactivity.

• These elements are noble gases.

Multiple Choice

What do the valence electrons tell you about an atom?

• If it is a solid, liquid or gas

• the melting and boiling point of the element

• the reactivity of the element

• the elements that are similar

Multiple Choice

What information does the period number tell you?

• Periods tell you where the bottom two rows fit in the Periodic Table.

• Periods tell you how many valence electrons the atoms have.

• Periods tell you how many rows of elements are in the Periodic Table.

• Periods tell you the number of energy levels or shells in an atomic model.

Multiple Choice

Which two particles make up most of the mass of an atom?

• Electrons and Protons

• Neutrons and Electrons

• Protons and Neutrons

Multiple Select

Which are subatomic particles?

• Nucleus

• Electrons

• Valence Electrons

• Neutrons

• Protons

Multiple Choice

When working with a chemical formula, how do I find the number of elements in that formula?

• count the small numbers behind the element

• count the capital letters

• add up all the subscripts

Multiple Select

Check all that are signs a chemical reaction has taken place.

• breaking a glass

• color change

• precipitate forms

• bubbles or fizzing

• tearing your paper

Multiple Choice

Using the formula triangle, what is the formula for Volume?

• D = m x v

• M = d x v

• V = m/d

• V = m x d

Multiple Choice

Which formula is also known as Newton's second law of motion?

• Density = Mass x Volume

• Speed = Distance/Time

• Force = Mass x Acceleration

The next part of this lesson will show you information you can fill in on the bottom of the formula chart side.

• This is a really good idea.

• Dump things you don't want to forget onto the formula chart.

• This way you can refer back to it as you take the test.

Multiple Select

When the light is on the right, it is---

• Waxing

• Waning

Multiple Choice

When the light is on the left, it is---

• Waxing

• Waning

Multiple Choice

Seasons are caused by ---

• Rotation of the earth on its axis.

• Revolution of the earth around the sun.

• Tilt of the earth on its axis

• Tilt of the earth on its axis as it revolves around the sun.

Multiple Choice

What is it called when one tectonic plate slides below another tectonic plate?

• divergent

• rift valley

• mid-ocean ridge

• subduction

Multiple Choice

Which type of reproduction produces more diversity?

• asexual

• sexual

Multiple Choice

Humans are considered--

• heterotrophs

• autotrophs

You can choose whatever you want to dump onto the formula chart--these were examples of important topics on the STAAR.

Be sure to: Take you time and read each question carefully before choose the correct answer.

Good Luck!! You got this!!!
