Brandon: I posted the rubric for the lab i thought i was supposed to be marking a lab report. I am slightly confused

Thanks Alex, I found it! And I agree it is much more complete!! I didn't notice it before! Ashley Hi-
 * Ashley,** go to "Manage Wiki" (above search box) and under the heading of Content click on "files". you will all the documents there. thanks.

This stuff is extrmely confusing...I agree too many damn versions and files (sorry).


 * KYLE**- you know, on my fifth thought...we should add a debate or city hall portion (mainly so we can have an easy evaluation rubric) and to barrage Sue with material. Want to add the directions for the debate or city hall portion under the STSE subheading?

Anybody have a ready made debate or city hall rubric? (**Brandon**?)

Another few hours and I think we are done... Alex (i'll refrain from posting for some time now)

Hi Alex, I didn't make any changes yet, it was just so confusing to have 5 lab reports posted! We can certainly use Lab1.doc, but I cannot find it on the list of documents that have been posted... Can you repost it for me? Thanks, Ashley

_ __H__i Ashlely- The lab you posted for handing in...(i like the pic). Can you use the Lab1.doc. This one has the chart, rules, and the small equations are correct and has the saftey chart (not sure yet where we want to put this). Not sure what other changes you made other than pasting the picture and the little solution/precipitation stick man and the proper spacing and such. the lab1.doc is more complete. however, if the changes require extensive time don't worry about it.

My thinking was that the links would make the issues more complete, even for a pre lab. So the students can explore the issues further on their own some time in the future (not likely but still). I prefer giving students all the resources that I used so they have the same info. (personally, I didn't know that phosphates were bad or such, still don't...don't really know their chemistry and such either...).

__ Hi Alex, sure I will add my pre-lab questions to the handout. Why would we want to add links to the handout? We cannot assume that students will be able to access the internet to do prelab research... We could assign textbook reading if we want. Or are the links for other teacher candidate? LOL that would be cool! Warm regards, Ashley

Hi- The following are the pre lab STSE handout (mainly pasted the background infro fro Kyle and added a few questions)...it would be ideal if we could add links and references to this page the post lab STSE handout (mainly added a few questions and added Kyle's action plan) the revised STSE setting (elminated most things and made a concise to the point of the setting and what we want the students to connect without going into any detail how, as in presentation, report, trials, city council...whatever.

Asheley, perhaps you can incorporate your questions into one of the handouts.

I don't see the little W icon, not sure if that means you can't just click and read, if not go the the files.

[|PreLab STSE Handout.doc]

[|PostLabSTSEhandout.doc]

[|Placement&STSE&PriorKNowledg&skills1.doc]

Not really clear on the topic of evaluation and assessment...any ideas?

Alex p.s.-I am not shooting for the gold on this. p.p.s-don't forget to write a self assement.

Hi, Ashley here. I will write up the pre-lab questions worksheet (including a couple pre-lab STSE questions that I generate from the STSE stuff Alex has posted - I will make the questions open-ended just to get students thinking about STSE and create student interest in the lab), and all of the other lab-related questions. I will print out a good copy of the pre-lab questions, final lab report, and lab questions (and answers) and bring them to school tomorrow. I will also print out a copy of all of the expected results and balanced equations. Is there anything else that I should do for tomorrow?! Regards, Ashley :)======

Hi- My thoughts. Am a bit confused. Not sure what people are doing and such. To clarify, I have separated our long report into its componenets. work on the component and we'll staple them together at the end.

1) lab (the actual lab portion) [|TheLab1.doc] 2) placement, piror knowledge, skills, stse[| Placement&STSE&PriorKNowledg&skills.doc]

3) lab evaluation rubric (brandons') [|lab rubric.doc]

We are done with lab the lab portion (with materials and saftety of the chemicals added to the end)

We are working on 1) STSE portion of Placemtn&STSE&PRIORKnowledge&SKills (Kyle? and Alex?) 2) lab Q and A (Ashley?) 3) map of the classroom lab (brandon)?

We need

1) a ready to use handouts for use immediately before lab (hopefully also containing questions petaining to STSE and lab) 2) A STSE direction for the students to follow-up and apply (with resouce links, and directions), expansion of STSE portion with directions (alex) 3) evaluation of their STSE partcipation and understanding.

Rereading the assignment where does it say that the students are presenting? It seems that all we have to do is show how the lab relates to an stse, and that is all. The students are expected to do the prelab, the lab, understand how it fits in the society, make further inquiry into stse.

to Kyle-lets stick with the phosphate example and that will be our intro to the STSE setting for the lab. I think most of what we have can be moved to the follow-up and apply section. we'll make the stse setting much more concise. And we can use your ideas of indiviudal chemicals for guiding the students to make new stse connections part (enlarging the stse follow up and apply section).

barium chloride (BaCl2), Inorganic waste, Restricted use, Store in secure poisons area, health hazard, highly toxic
Here is the rubric for marking the lab that i made.

Hey Guys

i am making the rubric for the lab and then making the safety section to do with our chemicals, i also have the lab set up sheet with the map of the classroom.

Brandon

Hi Ashley,

We still need to: (1) BLM on home work assignment on STSE topic including content expectations(2) Add in the presentation expectations, format and process (3) Presentation evaluation (4) Laboratory inclass assessment, laboratory report evalution

Did you want to pick from above and work on it abit

Alex: I did a data dump from a website that I cited in the documents..... I'm sorry I didn't make that clear early. That is why there is such as focus on phosphate. Maybe we can use some of the info to format what our presentation expectations are going to be???

Kyle So I am working on some questions right now, but what else needs to be done? There seems to be A LOT of info in the file below... Ash

From Alex



Updated version (with Kyle's specific expectations added...). I am really hating wiki.

From Alex

Updated version of our report. Red marks are where I wasn't sure.

I like your idea Kyle regarding assigning students one specific compound each and designing an STSE around that (phosphates, nitrates, salt, sulfat,es and heavy metals). We can make it more applicable than what we have so far (as I was updating I didn't like giving the example of just the phosphate detergents...as if we were the ones doing the assignment...so broadening it out and making itmore general (as in no examples, only their tasks) is a great idea).

So, for evaluation we have (I personally don't want to separate them into categories of diagnostic, summative or formative)

1)prelab worksheet 2)lab 3)Presentation

We need a rubric for the presentation (BRANDON?...thanks)

Alex Also, nothing changed in the previously mentioned red section (about dissociating and such). I just don't understand what you are trying to say. Can you reword it to make sense or explain to me what you are saying. Thanks.

Hi All,



Alex, I'm not sure what changed in the red section, I have haded the specific expectation which describes understanding how ionic solids disolve until saturation when a precipitate appears in the solution. The students should understand the difference between saturation and a precipitate forming from a chemical reaction. The is coming along. I noticed alot of editing work to be done but I figure it is probably best to leave some of the rewording until all of the content is in the document. I only made minor revisions such as fixing spelling and such.

I have added the specific expectations from the 2008 revised grade eleven university stream Ministry document. We need to decide on what STSE expectations we are going to use. The document encourages the use of an issues based approach (there are sample problems in the document if you want to take a look).

My suggestion for the lesson is as follows:

The students will be assigned one specific compound each (I would say we select 4 compounds from our lab) and asked to do STSE context research on the chemical prior to the lab. Phosphates, nitrates, salt, sulfates; these might be okay. They will then be put into pairs for the laboratory and a presentation. Each pair will do their pre-lab Q&A together. The Q&A will be a combination of their STSE research and their prior basic content knowledge on solutions, displacement reactions and precipitates. They will do the laboratory. They will be expected to hand in individual lab reports as a summative evaluation. The next lesson they will be given time to work in pairs to put a brief presentation together on their chemical. They will then be asked with their partner to present their chemical to the class. They will also be evaluated on the presenation. We might want to include a rubric on for the presentation. The pre-lab Q&A can be formative and diagnostic assessment with the teacher walking around and listening/reviewing work sheets. Does this work? Other suggestions? Kyle

Hi- I looked at what Kyle started and edited and added some minor changes. Kyle, can you look at the red part (only one part), I did not understand what you were trying to convey. It is my bedtime, so I'll work on the real meat of the write up (the stse portion) tomorrow morning.

I added an appendix III (just an examplar, (I just learned this word...i like it), the examplar isn't correct or finished). This could be their questions prior to the lab (i.e. homework) or we can shorten it and convert it to our Lab Q & A by adding few worded questions.

We need a Lab Q&A. Everybody contribute a few questions.

Brandon, add in the map and disposal in the end please.

Evaluation stratgies...don't know yet. Any suggestions would be great.

Also, disregard what I requested in class today about emailing me after you update. I wasn't aware of the NOTIFY ME feature.

Is the self-assessment a one page full on reflection?

Thanks.

Alex



Hello again,

I have started working on the STSE component of the lesson plan. I have done a little research and have copied some content from our stse booklet but this is all just a data dump at this point. Please do not think that I am planning on leaving the info in this format. I did not want to do any further work without asking for everyones feedback on the stse issue approach to the lesson plan.

My thoughts were that we would have the students do research on a compound that they will be testing in the experiment, possibly phosphates, chlorides, sodium, iron or sulphates. They would have to identify what household products and / or processes use these chemicals and how they find their way into our rivers and lakes. I would like to do some additional research on the City of Toronto website and possibly have the students link the chemicals to outcomes in the lake ontario environment such as impact to fish and other aquatic wildlife as well as the impact on society such as beach closures and drinking water qualities.

What are everyone elses thoughts? Were there other directions that we could take for this component?

I can meet tomorrow for a bit before class or afterwards to discuss.



ttys, Kyle Hi Everyone,

I have started adding some prior knowledge stuff to the the lesson plan. I have not added very much on STSE other than asking the students to do some research on a chemical xxxx (not currently selected) that has an impact on lake ontario. I will continue to work on the plan either tomorrow or Monday. Looking forward to your thoughts. Kyle Brandon: Hey Alex, can you email the lab once you make the changes so i can print it here at work? as well i am just doing the safety and map now, i had training all day yesterday as well as school and work today so i will bring the MSDS sheets, disposal and safety info for the chemicals. And i will make a map of the class, i wasnt sure if it was the map if each station or the whole class.

Alex: Wow...wiki is kicking my butt. I spent more time figuring how to navigate through wiki then on the assignment. I miss the days when communication was achieved by smoke signals (I can however see the appeal of a wiki...very nice...kudos Brandon). Oh by the way, Nice job Ashley (I think we can go ahead with the lab but I made few minor changes and I might make some more tomorrow before 10 pm). The major change was that I deleted the Unknown section from the data table. I think we should let the students decide how they should test it and which order. If we list it at the bottom of the table then (implied) the students only need to test with 4 horizontal chemicals rather than needing to test for all of them and being immersed in the results.

Baahhaaa ok I DID IT! WOOT WOOT

Ashley: Brandon, how do I post the Word document?... It's not working when I type in ... help! hhahaha Brandon: Awesome! If you guys want me to print or photocopy anything as long as i have it by thursday by 10 pm i can print whatever. I am going to make the map of the stations as well as the safety/disposal binder thing. I guess i will throw it in a duotang! Hey guys! Alex and I just finished up in the lab, and everything is good to go! I'm going to finish the write-up now and post it tonight!! :)

Alex: Thanks Brandon for setting it up (I feel so cutting edge now)

Brandon: Welcome everyone!
