1. As you walked in, you were handed a piece of paper. 2.
QUICKLY, get started reading this and filling out the sections
labeled Do Now. 3. We are doing a lab that I didnt originally plan,
so we need to not waste time today! Do Now
Slide 2
Announcements All classroom materials need to be with you by
this Friday! If you have problems getting the materials, talk to me
about it during independent work. Scientific Method test September
7 th.

Slide 4
Agenda You are all insanely smart. Group teaching: Scientific
questions Independent, dependent, control variables Cabbage
lab
Slide 5
Why? It is important that we understand the cause and effect
relationships between the independent and dependent variable. In
this class, we will be performing a bunch of labs and it is
necessary that we understand that we change the independent
variable to effect the dependent variable.
Slide 6
Scientific questions We will write our questions: How does
______________ affect _____________? Where the first blank is the
independent variable, and the second is the dependent variable.
What is the effect of _______________ on _______________? Where the
first blank is the independent variable, and the second is the
dependent variable.
Slide 7
Independent, dependent, control Variables Question: Does
brushing your teeth prevent the number of cavities you get?
Independent variable is the variable that you change. IE: Brushing
your teeth Dependent variable is the variable that you measure. IE:
number of cavities Control variables are all the other variables
that remain constant throughout and might not be exactly stated.
IE: Eating after brushing your teeth, type and amount of tooth
paste used
Slide 8
Homework Procedure I will assign homework weekly. You will
write your homework in your calendar for the week on Monday. You
will need to get this sheet signed by one of your
parents/guardians. When homework is due, you will turn them in
before class into your classes basket. If you are in my first block
class, your homework will go into the bin labeled 1 st block.
Slide 9
Paper Passing I dont really feel like we need to go to in-depth
on this. However. When passing papers back, take one off the top
and pass to the person behind you. Do not fool around, youre just
wasting time and being petty.
Slide 10
Pencil sharpening I hate pencil sharpeners. Theyre loud,
annoying, and just a pain. I have a handheld pencil sharpener. You
may raise your hand at any point if you need to borrow this in
class. Please try to get your pencils sharpened before class.
Slide 11
Cause and effect relationship Try and explain to your partner
how the relationship between the independent and dependent
variables is comparable to a cause and effect relationship. When
working in partners you must: Stay on task! Be respectful to each
other! Listen to your partner.
Slide 12
Cause and effect relationship continued When you manipulate
(change) the independent variable, it directly causes the change in
the dependent variable.
Slide 13
Practicing variables In partners, figure out which is the
independent, dependent, and control variables. 1. Does fertilizer
make a plant grow larger? 1. Independent: Fertilizer 2. Dependent:
Plant growth 3. Control: Sun light, water 2. Is a classroom louder
when the teacher leaves the room? 1. Independent: Teacher 2.
Dependent: Noise level 3. Control: Number of students, directions
about whether they can or cant talk
Slide 14
Group Work Raise your hand silently if you have ever played the
game Dice, Dice, Baby. RULES: You need to get out one piece of
paper between you and your partner and then split it in half. YOU
EACH SHOULD HAVE A HALF OF THE PAPER! Do not write on the
paper!
Slide 15
Dice, Dice Baby You will be getting 1 die between the two of
you. Partner 1 will roll the dice until they get a 6. While partner
1 is rolling, partner 2 is going to be identifying the independent,
dependent, and control variables for a series of questions. When
partner 1 rolls a 6, they will grab the pen out of the partners
hand (GENTLY!). This game can get intense fast. Lets try not to
hurt each other
Slide 16
Exit Ticket Identify the independent, dependent, and control
variable for the following scenario. 1. You want to test whether
the amount of sugar you eat in a day has a direct relation to the
amount of energy you have in a day. What are the independent,
dependent, and control variables?
