One of the best parts of teaching for me is finding ways to make learning relevant to student’s everyday lives and future.

We have been learning all about classroom chemistry this term and the topic itself is one of the most engaging and exciting units we have delved into so far. The students are learning about chemical and physical reactions, solutions, mixtures and the three states of matter through various hands-on experiments. One of the main outcomes for this unit was:

  • Produce carbon dioxide gas through the interaction of solids and liquids, and demonstrate that it is different from air.

So, the most relevant way for students to understand this concept was for us to get messy and bake our own bread! And just for additional learning, we also incorporated measurement and math understandings while in our Foods Lab by converting oz to ml, g to cups and differentiating between teaspoons and tablespoons.

My students were so eager to learn about cooking and baking because they see it everyday but have not been able to be a part of it yet and most importantly understand the chemical processes that occur when creating a meal.

Their main focus going into this lesson was observing and creating different chemical and physical reactions, solutions and mixtures while working on everyday life activities such as baking a loaf of bread. We learned and brainstormed together prior to engaging in the Foods Lab and students wrote down their hypothesis and their understandings of the criteria. Each group was provided with the same basic bread recipe and they asked if they could add variations. They worked in groups to determine what variations they wanted to include and how that would affect the reactions they were looking for.

The were absolutely amazed watching the tiny yeast granules activate with the warm water and the sugar. The shock was even more so when their loaves began to rise and through the glass pans they could see the carbon dioxide pockets.

Here two videos of a few of my students sharing their bread with fellow teachers in our school and explaining their learning:

When we went to cut their loaves, I heard comments like ” It looks exactly like store-bought bread!” and “This is the best bread I’ve ever had!” I told them it sure is…because you made it yourself!

They also all blogged their reflections and observations on our classroom blog: www.psdblogs.ca/dariss

Next up for us is a Bake-Off Challenge this week with three executive chefs where students are going to be provided with $25.00 and will have to make their own food creations that feature 2 chemical and physical changes and 1-2 mixtures and solution.

Classroom Learning – Feb. 9 – 13, 2015

This month has been flying by as its been full of short weeks filled with a lot of activity! My students have been hard at work but we also made some time for celebrating the work and learning we have been doing.

Language Arts

We are well into our read aloud Wendell The World’s Worst Wizard. We have learned about the differences between gnomes, elves and trolls as well as wizards and witches. The students have been reflecting on their connections, inferences and predictions as well as other criteria as we move forward into this story. They have each chosen either a specific character from this book or a type of character and started brainstorming their profiles so that they can create depth for their character when we begin their narrative writing pieces next week.

This week we discussed juicy adjectives and descriptive words. Students researched a variety of words and then applied those to their peers in our Friendship Adjectives Hearts:

Each student left a descriptive adjective about themselves and their peers on their heart.

Students have also started their book clubs! I have never seen more excitement and enthusiasm for reading in all of my years of teaching so watching them jump for joy when books where distributed was wonderful! I credit this in part to the fact that they all chose their own books based on interest and abilities. They all decided within their groups as to how much they will read before providing reflections. Each group also created a collaborative Google Doc which they will record their questions, comments and information to share with me and the classroom.

Here are some photos from their meetings:

Mathematics

We are nearing the second loop of feedback for the student’s Resort Reports. I have asked that they each work on them this weekend whenever possible so I can provide them with additional audio feedback. They will be given more time next week to listen to feedback and apply to complete their work. I have loved using the add on Kaizena for the audio feedback!

Science

We completed a brief experiment together on growing crystals and students were able to observe their findings from last week’s  solutions.

Social Studies

The student’s jot notes and research skills are moving forward as they continue to research the two regions of the Arctic and the Great Lakes LowLands. I assigned each student a google doc for jot notes and one for a bibliography. They are loving using the add on Easybib to create their works cited. They are using both text and online resources and have learned how to cite each resource. They then also created two separate Google Presentations focused on each region of Canada and will compile their research into a personal presentation with a focus on guiding questions.

Valentine Buddies

This week we also gathered with our Grade 7B buddies to work on our collaborative art. We decided that this would be an awesome time for us to make our buddies some Valentines and they created some for us in return. We also set-up all of the treats brought in from both classes and shared while working on art together. It was so heart-warming to see them so excited in making, distributing and receiving Valentines. I truly believe one is never too old to celebrate love, kindness and friendship.

Distributing our Valentines and reading them!

Skiing

We received some high praise from the ski instructors at Rabbit Hill Ski Resort on Friday. Two instructors approached myself and Mrs. Krefting at the end of the day with huge smiles on their faces and asked us if we were with the students from Greystone. We said yes, and they began to say how absolutely wonderful our students were. They said they have never had such an incredible group of kids who listened and were so respectful. They were so happy with them that they wanted to give them something and so they opened up another area for them that they normally never do. They wanted us to let our kids know just how much they were thankful to have worked with them today and they also said please bring them back anytime!

To say I am proud would be an understatement!

I tried to capture some photos of everyone skiing, however most were so far up on the hills that I was only able to capture a few in action.

Classroom Learning – November 24 – November 28, 2015

November has flown by in our room and we are looking forward to bringing together all of the incredible projects and learning we have been doing this term.

The following is an update on the activities happening in LC5B!

Language Arts

We have started a group read- aloud on the book “Out Of My Mind“. Its an incredibly powerful story of an 11 year old girl diagnosed with Cerebral Palsy and the social and academic challenges she faces. The students have made some deep connections with the main character and are learning how to express empathy and understanding. I am reading this book to them and together we are discussing our thoughts and feelings. The students have also started to blog their own questions and understandings.

We are continuing with our daily reading and ensuring every student has access to reading materials reflective of their interests and ability. Please do let me know if students are not bringing any material home for additional reading time when possible.

Mathematics

We are shifting our main focus to multiplication now, however place value and estimation will still be a continued focus year-round to ensure understanding. The students are also meeting in three smaller groups for two periods a week with Mrs. Krefting’s class to work on combined skills and we continue with our problem of the week every Friday.

This week’s problem was called Grasshopper Jump Fest and I was so proud to see everyone just dive into solving it in their own ways. Students have now built the confidence to attempt problems without fear or hesitation from the work we began at the start of the year. We are working now on how to explain our thinking and how we are actually solving problems. This involves a strong understanding of one’s own strategies and how and why they applied those.

We all have our own strategy for solving the problem!

A few of the students were so proud of their process and in demonstrating their understandings that they asked me to video them solving the problem. As you can see below, some succeeded and the ones that didn’t during this taped version, continued on despite that fact and then refined their process with the feedback from myself and their peers. At the end of our lesson, they had all achieved success and began their reflection blogs.

Science 

We are wrapping up our units on Electricity and Magnetism. The students are working on their final projects which is to build a mechanism that features a working circuit and an element of magnetism. They have all done their research and will begin to plan their experiments this week. Our next unit is weather which will be a year-long focus as weather is happening every day around us. We have started watching and interpreting the weather radars on the weather network as well as tracking weather systems heading our way and globally. The students were fascinated by the extreme snow conditions in Buffalo, New York last week and began to question how being surrounded by lakes causes a Lake Effect. They also started to make connections between that and our location in Alberta versus British Columbia.

Social Studies

The students are now working on putting together their presentations with the information collected from you about their histories and heritage. They refined their questions and understandings last week and started exploring different presentation options. They were provided with a few technology tools as well as poster and paper options and were asked to choose which style worked best for them to represent their families’ story.

Art

We love art in LC5B! Its never an easy task but it allows for students to demonstrate their own creativity. We worked on the use of chalk pastels and the aspect of defining space. Students are often asked to fill in every piece of a project and not to leave any white spaces, however with our chalk pastel pieces, that white space helps to define texture. Students were pushed and directed to actually colour outside of the lines and to make their images rough and not refined.

These are their scruffy Woozles:

Implementing Our Electricity Understandings

We have been working very hard in LC5B learning about electrical mechanisms, circuits, batteries and just how electrical circuits operate.

This is a fairly in-depth unit and the students and I have approached it with inquiry in mind. We are surrounded by electricity, but just how does it work and how dependent are we on it? LC5B had come up with so many questions which we have taken the time to research and learn about what we wondered.

Last week we had failed attempts at implementing a working circuit, but our focus at that time was on the process and how to continue to try alternatives when coming face to face with a failed attempt. This week we focused on applying the skills and knowledge we had learned about functioning circuits and attempted to put them to test with our circuit boards.

Students chose partners they felt they could work best with and each group was provided with an operating circuit board and the cell batteries students were asked to bring at the beginning of the year. I didn’t provide them with any further instructions other than to make their circuit operate. We had built the foundations of what an effective circuit requires in order to function, and now they had to apply this knowledge. This was the best piece of assessment of learning as students were quick to begin and were incredibly focused and determined on getting their circuits to operate, and they applied their understandings of insulators, conductors, switches, cells and voltage. They were also 100% comfortable in explaining how and why their circuits were or were not working, which allowed me to see their understandings in a natural setting.

They explored, they pushed, they clipped, unclipped and re-clipped….and may have burnt some bulbs…but they were learning!

I hope you can see and hear their excitement below:

What happens if.....

Let's see what this does...

Classroom Learning – October 16, 2014

Building community within a group of diverse learners is not a one time lesson or activity; it is an on-going and continuos conversation. As we get to know more about who we are as a team and how to work well together, certain themes continue to arise:

  • Demonstrating respect for one another
  • Showing care and understanding for one another’s needs
  • Taking personal responsibility for our actions
Sharing our promises to our learning community.
Sharing our promises to our learning community.

We took some time in the morning to review these conversations and to express what we are each bringing to the team. Students the shared out loud to the class to demonstrate ownership of their contributions.

In Math, we started to learn about estimation and rounding strategies. The three we are focusing on this year are Front-End, Compatible and Compensation. Students are learning how and when to use each strategy and the reasons behind why estimation and rounding is so important.

In Language Arts, we continued to read The Fourteenth Goldfish with our Global Read Aloud and make predictions. We also located a large Google world  map that had been started by a participating classroom detailing locations of all of the classrooms reading with us.

We then located Spruce Grove and placed our pin amongst the hundreds of others. Students immediately wanted to differentiate themselves and had figured out how to re-create the pin icon in Maps. We changed it to a fish, but in doing so….we accidently also changed everyone else’s! We hope they like our icon…

The afternoon was focused on Science as we learned what a circuit is and how it works. We worked through The Blobz Guide To Electric Circuits together and wrote the important information we would need to know when it comes time to building our own circuits and electrical inventions.

One of our classmates has a deep passion for creating and building electrical devices. He had brought in a fan he had built using batteries, wires and a computer fan. Once our discussion led to the use of batteries, negative and positive charges, the students asked him to show us what would happen if the batteries were not placed properly in the circuit.

What will happen if the batteries in a circuit are not positioned correctly?

Last week I had brought in a MakeyMakey that a teacher friend of mine generously let us borrow to experiment with. The students were absolutely fascinated by the intricate details of the circuit and after learning how circuits operate, we decided to try it out. No one knew how to operate it, myself included, but that was what made the learning more fun and authentic.

We used carrots that one of the student’s had grown at home, along with my laptop, alligator clips, the MakeyMakey and connectors. We finally got it working due to the student’s perseverance and sheer excitement to make it work : ” Try this!”, “It’s that cord!” “No, maybe this way?” until we saw the cursors on the laptop work through the circuit we built!

It was a great day full of learning! Students have been asked to find the electrical mains in their homes as well as research different ways we can use a MakeyMakey.

Do you have any suggestions or ideas for us in creating circuits?
