Hacking the 8th Grade Science STAAR test - Periodic Table Brain Dump

Teach students a bran dump strategy to help them be successful on 8th grade science STAAR test day. This is the periodic table brain dump (1/2)

The formula chart brain dump can be found: https://www.youtube.com/watch?v=S-9YNlewliY&feature=youtu.be

I this is the

eight grades star reference material hack

we want our students to do this before every test once they get the star test

we want them to pull out the periodic table

in the formula chart and to start writing all

the on information that we provide in this video

this is a brain dump will allow you to you happy the star test let’s keep going

on the first thing we’re going to talk about is we want to make sure that

eat is represented on the periodic table in eat just means that

the atomic number equals the number of protons

equals the number electrons

you put that right up there by be given boxing pitu

number two were gonna point in a row right at the atomic mass

and we’re going to denote that means on

protons plus neutrons stand next to you right

on your interview number three we’re going to talk about mass now our scheme

and now

so me n is an acronym that means atomic mass

minus the atomic number equals

the neutrons so you’ll see the

im in mass in the a an atomic number

in the in in neutron or are an acronym for

this little many formula and you can even certain let me in

you’re ever given a problem we need to find neutrons

begins plug in your information given in government fourth

real time I were the valence electrons are on the PRT went hiking determine how

many be words like Jones Beach particular element hands

someone right valence electrons up at the top here

demanded ransom a rhodes to

each of the groups and families just a couple the group Mac and Roger each one

of them

and our circle the group number or the park a big group number that represents

valence electrons notice that group 1&2

are also one mailings like John into man’s like Charles

then we start working online group 13

through a team and Rockaway rose over maybe 1318

and we have to drop to one of to make sure that

we have the correct number valence electrons sovereign example on this one

is group 13 but only three

valence electrons and in the next will be grouped

14 but only for Palin’s like chance

so everything in that group were in that family

you are the same number valence electrons in the same reactivity

II now we’re gonna move up to talking about groups or families a little bit

more some

above about 16 group 16

we’re gonna write

on these are called groups or families in the Thomas Circle

this particular grouper family what this means is that

everything in this group or family has similar

properties and similar reactivity

so I’m gonna also put a

box around 16 to show that that’s the

group number know when she confused the group number with the

mainland’s lecture on them this is actually the phone number there

so in this particular case oxygen sulfur

on in so for selenium to learn they’re all

going to be I’m so have similar reactivity

are up moving on we’re going in now

go over to you the roads which are called

periods on the periodic table

make sure we have reactivity on here because that’s what that

group number tells us meals electrons

and so now we’re gonna move over to the periods and

these are the rosies with the horizontal rose going across the beer cocktail or

and they tell us on couple with everything details number

energy levels and then tell us the number

energy shells in actual more

model so I was gonna label periods cross the

side here output in parentheses energy levels

he and energy shells you be real surprised how many questions will pop up

on the star test that will be answered by just having this room bring dumping

now we’re gonna move down to the bottom of the periodic table

we’re going to talk about reactivity real quick

I’m gonna draw big long aerogel right

to left and I’m going to label it

increasing reactivities has the Aero

moves toward the lapd rise the group moved toward the lapd

they get more reactive so is gone awry increasing activity down towards the

bottom

the most reactive group for family

on the periodic table is group one so many despite a littles

I most reactive down there so I know that those are highly reactive

they have one valence electron and they want to give nothing away as fast as

possible

may react

very violently with a lot of different other elements

now going back to the other side group in

team these are the most stable someone right most stable down here

and this group has a special name its call

the nowww gases so shriner need

the the on element raid on a mission right noble gases just in case that

happens that pop up on a test but these guys are real stay with me

they’re not giving any electrons away their electron shells are totally fall

II so the black table strongly marked up

now we want to go to back to the top the periodic table

you wouldn’t start talking about different other chemistry principles

summer focus in on this top left corner and

on room first talk about compound

known as glucose which is c6 each 12

06 gonna make some comments about it real quick seen this before shop on

previous start ass

so three elements it has three elements and you do that by counting the capital

letters

carmine hydrogen and oxygen so

three elements out to the side there and it has a total

up 24 harlem’s we do that by counting the subscripts that’s the little number

behind each other the particular elements

if they’re is not a number there then it’s implied that is one

I’m you cannot how the latter and not have

happens so it has to be a one this case

is 24 happens I the next thing you know

you know that chemistry is the rap

acronym that we gave you in this is talking about balance

on balance equations on each side

the Aero there are reactance on the left

and products on the right in order to be balanced

they have to have the same number on each side

same number Adams we call this route because

there’s an are reactant the he stands for the

a row in the P stands for the product right

Stoli balance than those numbers would only matchup

okay now asking the subatomic particles

we’ll be talking up protons neutrons electrons first we’re going to talk

about protons

protons am realistic

charge which is positive near found

inside the nucleus zooms in a little bit more so you can see it

right and then next we have a neutron

which is

a negative charger no excuse me and no no charge

are neutral charge and near found inside the Adams well

and then the electron

which is negative and brown

outside the nucleus also wanna make no

top two the protons and neutrons

make up the most mass up the Adam

this is where all the masses found in the AM electrons

have tiny tiny little be a math mass

but not that much muscle mass comes from the protons and neutrons

in and she moved to the top right corner of the sheet

renowned talk about metals middleweights

and nonmetals some metals recalling those

on the left side appear table so basically anything to the lapd beam

the staircase on the periodic table were saying

is him at all an answer my own properties air she never shiny luster

a I means they’re shiny when you look at omnis the way the light

reflex of them and then they are valuable which means they can be pounded

into sheets

they are also good conductors

in their poor insulators could also mention that there

ductile as well means they can be

polled into a wire you’ll see in copper wire

in all your electricity run your house your school

right next to talk about the middleweights in metal lloyd’s

are found on usually

touching this staircase on the pier on tables and touching that black line

looks like a staircase

on the periodic table in all those are metal woods except for one which is

aluminum in ashes when you have to remember is

a metal you think aluminum it does look like it has lots of properties in metals

make sure that you know that that is actually in metal justice that pops up

alright so metal what’s up their properties both

marking a list all the problems you just you just you know their properties both

they could be

shiny in a QB brittle cell

alright and then lastly we have non metals nonmetals

are on the right side iraq table general region not generally the

are too right the staircase and they are

mostly gas there are some exceptions that just like everything in science

and they are dole meaning they have no shine to them

something chalk when you think a bill you cannot talk is not an element has a

don’t actually near good insulators in the

are poor conductors

writes that this is the periodic table you can see it didn’t really take that

long to

to fill this out I don’t all my knowledge

I don’t appear on table in this is going to help me answer

many many many chemistry questions that can be thrown at you on star test

I’ve got thirteen different concepts on you

I would guess that if you knew all of this

that you have would have him very very good shot

passing stars knowing this part of the chemistry we’re going now

flip it over to the back and work on the formula chart

in a couple of other models that we like you did wrong
