Preassessment
For the pretest assessment, I went for a more concept-based idea check rather than specific questions.
The data coming from this assessment to tell me where individual students are. I based the unit off the
book which has objectives for the lessons which guided me to write the following questions as a
preassessment.
How would you define chemistry?
When you picture a chemical what comes to mind?
Complete each of the following:
549+328 =
893-423 =
234/51 =
67*22 =
Explain a time you have used each of the following: Inches, Feet, cm, miles.
Identify what each of the following are measuring: meters, Liters, seconds, and pounds
Assessment Plan Overview/Alignment
As formative assessment, I will use the questions above to guide my discussions, and use them as
closing questions where I will collect responses. Looking at the responses will tell me where students are
at in terms of making progress. For week 1, I want students to use flipgrid to show chemicals they
encounter all the time. The assignment is shown below:
The rest of the closing questions which students would write on a sticky note are shown below:
For the first closing, I will have students write down what they would define chemistry and chemical as
after defining them to them. I also will ask them the same question the next day to start class then we
compar and reflect on results.
For this one, I will make sure no students wrote down their address as that could lead to issues.
For all of these, no points will be assigned. I will stress that the information would be used to inform me
and the students should not stress about these questions. The only points associated will be with the
density lab which if students show effort, they will get credit for that part of the lab.
For Summative Assessment, I am required to use an exam and I will offer an option to do a practical. I
get that for some students however, a pracical would be too much. The test that I wrote for students to
follow is written below:
1. How many significant figures are in each of the following?

of the HDL in grams/mL?
For their topics of discussion, the students will focus on one topic from chapter 2, and for the individual
assessment time, I would give them one problem associated with each of the unit objectives.
Adaptations
Every student has different needs in a classroom, so to take care of each student to the same extent I
offered a couple different assistance methods. For each student if they didn’t understand a question, I
would read it to them and then explain to them in different words what it is asking if they still didn’t
understand it. Also, I would give students all the time they needed to take tests, and allow retakes for
students with testing anxiety.
