Let’s try one together!
What Shape are Cells?
Cells can have lots of different
shapes. In this lab, the animal
cell was like a wavy circle. The
plant cell looked like a
rectangle. The bacteria was
squiggly. Since all these cells had
different shapes, I can tell that
cells don’t just have one shape.
What Shape are Cells?
Cells can have lots of different shapes
(claim). In this lab, the animal cell
was like a wavy circle. The plant cell
looked like a rectangle. The bacteria
was squiggly (evidence). Since all
these cells had different shapes, I can
tell that cells don’t just have one
shape (reasoning).
Let’s try another one together!
Do you think the “scar” on the
Atlantic Ocean floor is a ridge or
trench?
The scar is a ridge.
Station
Elevation
1
-5700 m
2
-3300 m
3
-5700 m
The elevation of the scar is higher than
the two stations on either side.
Do you think the “scar” on the
Atlantic Ocean floor is a ridge or

The scar is a ridge(claim).

(evidence)
The elevation of the scar is higher than
the two stations on either side
(reasoning).
One more together!
Mr. Garcia: Do you think the climate is
changing? Make sure you support your idea
with evidence and reasoning.
Olivia: I think the climate is changing because
this fall has been really warm.
Mariela: Does being warm just one fall count as
evidence for climate change?
Nate: No, climate is long term changes. It is just
weather if it is one day or a month or a season.
So I think it is changing because the air
temperature has slowly gotten warmer over a
long period of time. The average temperature
has increased 2 degrees over the 100 years.
