What to Teach in the SNC1L / SNC2L Science Courses – Post 20
The Ontario Ministry of Education provides us with well thought out course outlines as well as detailed course profiles. These resources are an excellent starting point, especially for the new teacher. But, due to the nature of the learner in these classes I suggest that these two high school science courses are probably the ones with the most flexibility built into their curricula.
There are five units of study set forth for each of the courses. In grade nine they are:
Unit 1 Scientific Inquiry: Science in Daily Life
Unit 2 Biology: Staying Alive
Unit 3 Physics: Electrical Circuits
Unit 4 Chemistry: Properties of Common Materials
Unit 5 Making Personal Decisions
In grade ten they are:
Unit 1 Scientific Inquiry: Science in Media
Unit 2 Biology: Living Together
Unit 3 Chemistry: Interactions of Common Materials
Unit 4 Physics: Using Electrical Energy
Unit 5 Community Action Plan
The Ministry’s intention for the course is that the first units (Science in Daily Life and Science in the Media) be interwoven throughout the course content. In the grade nine course students examine personal and workplace situations with an emphasis on health and safety, for both themselves and others. In the grade ten course relationships between the student and the environment, the effect of individual choices and actions affect the community, and an individual can make a difference in his or her community.
It did not escape my notice that when the entire high school science curriculum was overhauled by the Ministry in 2009 the only courses that were left untouched were the SNC1L and SNC2L courses. I don’t know why this is, but I am sure that the Ministry has their reasons. One consequence of their failure to act means that these are the only two courses offered in my science department that are not subjected to the “big ideas”. The “big ideas”, as every high school teacher in Ontario knows, are the over arcing themes that the learner needs to take away from the course with them.
As an experienced science teacher who is intimately familiar with the documents used in our system I would venture to suggest that these are the big ideas:
Grade 9 – Health and Safety
Grade 10 – The Environment and what one can do to keep it healthy
So what should one teach? Here’s what it comes down to:
1. What the students want to learn,
2. What you are comfortable teaching,
3. What facilities are available to you?
What the Students want to Learn
The units defined by the Ministry and listed above are great suggestions, I have focused on all of them in various ways over the years but what one should really teach is what the students want to learn! How do I know what the students want to learn? Simple, first of all I ask them and secondly, I observe them.
It is not uncommon to have non-verbal students, or those identified with other types of communication exceptionalities, enrolled in these science classes so asking them has to be done in a different manner than just standing in front of the class and asking, “What do you want to learn?” Instead one must set the stage and employ some unconventional techniques to get the students to communicate their desires to you. I have the advantage of teaching in a real science lab so there are lots of visual prompts all around my room to get kids thinking and talking about science, these include lab equipment, posters, an aquarium, books, safety equipment, the layout of the room, examples of student work, a word wall and even an attached greenhouse.
To get the kids thinking about science and what it is we often do a walk-about where I point things out and invite discussion about them and also ask lots of open ended questions. Such questions usually begin with a how, what, when, where, and why. So I can point to a glass-fronted cabinet full of beakers and ask, “What could these beakers be used for?” or I can take the students into my greenhouse and ask, “Where could all these plants have come from?”; or I can offer a carrot stick to the turtle in my aquarium and say, “Why does this turtle like carrots?” The beauty of asking opened ended questions like this is that there are (almost) no wrong answers and gradually everyone becomes engaged, even if they are not talking.
The question remains, “What do you want to learn about?” After the students have completed their walk-about I give them large (8 cm x 13 cm) sticky notes and have them write, draw, sketch or DOODLE the answer to the question. Oh yes, research tells us that doodling is actually thinking in disguise! Each student is invited to tell the class what is represented on their note and post it on the front board. After class, I collect all the sticky notes, jot down what they mean and file them away. Now I have my ideas for the semester! Inevitably you will have someone who wants to “blow things up” and someone who is interested in “outer space”. The first is easily accomplished by demonstrating blowing up a gummy bear whereas the second is an excellent segue into a research inquiry.
What You are Comfortable Teaching
Another important thing to consider when planning your semester is your own strengths and weaknesses. One of my passions is caring for the environment. I have kept a vermi composter for years and have integrated it into many lesson plans, which I will blog about soon. Go with what you know and love, your passion is contagious!
What facilities are available to you?
The facilities available to you are also an important consideration when planning your curriculum. For example, if you have no fume hood you probably don’t want to be blowing up gummi bears! If you don’t have running water you are limited even more. If you are in a portable, may God Bless you! Since I have a greenhouse I do lots of projects that involve plants, their germination, fertilization, growth rates, etc but don’t dwell on what you don’t have, look around you, take advantage of what you do have! Your biggest asset is the students and no matter where you are assigned to teach you will have those! And never overlook the myriad of learning opportunities right outside your classroom door – both inside and outside the school. Setting up a school recycling program or doing an electrical use audit gets the students out of their desks and into the rest of the building. And once you walk through the school doors, even if you remain on school property the possibilities are limited only by your creativity!
Have fun and good luck!

Teaching Science to the Special Needs Learner -- Posting 19
The students in these courses usually have a number of learning challenges. It is unlikely most of them will be success in the Ontario Secondary School Literacy Test (OSSLT). Most of them will probably be except and will be graduating with a certificate, not a diploma. When I am looking for science resources to use with them I usually look in the grade 4 – 5 level.
Now that I am a Smarter Science convert it makes teaching these students more fun than ever! No more cookbook labs. The students are in charge of what they learn and how they learn it.
Here are a few tips:
1. Treat them with respect! This may seem self evident but I have often had students tell me that this was the first time they didn’t feel like a dummy in class. Celebrate their successes, every time! When someone reads something for you tell them “Nice reading”, when someone asks a question respond with “That’s an excellent Question, I am so glad you asked”, when someone asks an inappropriate questions say” “This is not the time for us to discuss that but thank you for putting your hand up”, when someone screws up a lab tell them “some of the best scientific discoveries have been made by scientists making mistakes, you might be looking at the Nobel prize one day”. You get the idea.
3. They must treat each other with respect! Inevitably there will be a student in the class that believes they “do not belong there”. This may be manifested overtly by call
4. They are “real scientists”! A real scientist has to know all about lab safety and wear their safety equipment at all times. Even if the students are simply boiling water and recording its tempera
5. Lab safety The most important thing for a science teacher to ensure, in any class, is the safety of the students. With most classes we simply hand out lists of rules. In order to prove that we have done our due diligence this is not acceptable with these learners. In the case of an accident a parent could quickly argue that a student with below grade level reading compression could not possible be responsible for knowing and understanding the safety rules. Furt
6. Structure, structure, structure! Being in a big high school with different faces in each class, at least four different teachers to contend with, moving through the crowds in the hallway, all these little things that most teenagers thrive on can be overwhelming for the learner in essential level classes. Therefore it is paramount that they know exactly what to expect in science class. By removing their anxiety you have opened the door to learning. Your structure will be determined by you and your classroom set up. Here’s what works for me:
· We keep our binders in classroom.
· Prior to their entry put a short list of what will happen in class on board. This can be super simple. For example:
o Return worksheets
o Discuss today’s weather
o Take note
o Video
o Do lab
o Clean up
A list like the one above can serve many purposes. A common question the students will ask, once they are comfortable with you will be”What are we going to do today?” to which you can reply, “It’s on the board.” Since many of the learners will have weak literacy skills they will help each other read it. This will happen naturally and there will be ad hoc discussion around what it means. Encourage this; it leads to predicting and inferring, both of which important skills for building literacy (See how easy it is to embed literacy across the curriculum!) It also allows for some social interaction which is also something these learners often struggle with. Another important skill you will be teaching by having this short list on the board is “How to use a checklist”. Incredibly this is an essential skill identified by the Conference Board of Canada as being important for employability in many jobs yet our students are unfamiliar with them. As the lesson progresses refer to the list and check things off as they are done. Try to provide the student s with a check list of their own from time to time, for example, as part of a lab procedure, etc.
· I always stand at the door to greet the students, BY NAME. For some of these lost souls their names are all they have, honour them by learning it and using it. If a student is named Timothy and only likes to be called Timothy do not call him Tim, without his permission. This year I had a student named Antonio who insisted on being called TJ, don’t argue, just do it.
· As they enter remind them to pick up their binder on the way to their desk.
· Always have the date written in the same format, on the same place on the board.
· Insist that every single piece of paper be dated and put into the binder, in order by date. This sounds so easy but is a HUGE challenge for these students. You may want to keep an ongoing list of what should be in the binder, in the correct order, posted somewhere in the classroom. Once a week go through the binders together to make sure everything is in order. They can even be taken in for marking. Why? Organization is another essential skill that these students often need to work on.
- Notes
Whenever you do give a note ensure it is read aloud and discussed. If the students simply copy it down they will have NO comprehension of what they have copied.
- Print Resources
Do not look for a text book to use with these courses. These students are not about textbooks.
McGraw-Hill has published workbooks and teacher’s guides called Essentials Science 9 and Essentials Science 10. These are excellent!
You may find the useful articles in magazines that are geared to younger learners. Two magazine I have found helpful in the past are Science World from Scholastic, each issue comes with a teacher’s guide and Yes! Science magazine.
- Video Resources
These students are not able to watch a video and answer a worksheet at the same time. If you plan to do this you will have to read the worksheet one question at a time, pause the video after each question , re-read what the questions was, rewind and show the answer again, discuss it, write it on the board for them, wait while they copy it down, read the next question, repeat. I’m sure you can see that this will become very tedious. Here’s how to make it work:
Write one question on the board, for example; “At what temperature does water boil?” Before putting someone on the spot by asking them to read the question out loud tell the class that is what you are going to do and for everyone to take a moment to read the question silently to ensure they know all the words – some of the students may use this opportunity to confer with you, a TA or each other is they are unsure of any words. Have a student read the question out. After the question has been read out loud discuss it, either all together, a think – pair – share, whatever works in your classroom. Now you are ready to show a video clip which will answer the question. After watching the video clip discuss what the answer is. Oral communication is key!
Video Clips
This is the way to go! Two minutes maximum! As you know there are a zillion on you tube. Because I do not trust our internet connection at school I always download them onto my memory stick using free software called, Clip Extractor.
Bill Nye videos
The kids love these videos, but there is too much content for them to absorb.
I like to use them to show Bill Nye, or one of his colleagues, doing a lab. Then we do the lab. Or visa versa. We do the lab then watch it on the video. This helps the students feel like “real scientists” because they see other “real scientists” doing the same thing.
Most Bill Nye videos are available on you tube. The New York Teachers website has worksheets for most of them (good for the applied level.)
- Labs
This is the most important component of the entire course. This is the “hook”! Do at least one lab activity or one demo every day! This sounds insane but for these students almost anything is a lab. Take the temperature of the cold water from the tap and the cold water from the fridge then compare it. That’s a lab. In fact, be creative! This lab could easily take up more than one 75 minute period.
I like to train the students on one or two key pieces of lab equipment and use them over and over during the course. One of my favourites is the graduated cylinder. Why, you ask? First of all, only “real scientists” use graduated cylinders. Where else do you see them? No one has one at home or in their car. Secondly, I happen to have a bunch of plastic graduated cylinders in my lab. (Glass ones can be very expensive.) Thirdly, they are easy to learn to use. I have an entire set of worksheets on “holding the meniscus” as eye level”. Always wear your goggles! Spills can happen! And finally, measuring out a fluid (I like to use water a lot!) is generally a safe part of many labs in the essentials science course.
This semester I am using the beginning scientist Smarter Science framework to help the students work collaboratively to put their thoughts in order, then design and carry out their own investigations. You can see an example of this on my past three blog postings.
Conclusion
You are a hero if you have read this far! I just have so much to tell you. Instead I will stop now. Send me any questions or comments you may have.
Also, you are welcome to come into my classroom anytime to observe and visit. Maybe we could even plan an activity where we get out classes together.
Hope this helps and GOOD LUCK!
