How To Build an Awesome Car (Engineering Thinking in Grade 4)

Traditionally, Grade 4 "Wheels, Levers and Devices that Move" units involve hands on investigations in which students have the opportunity to build something. Often however, these building opportunities are heavily regulated and have students follow a specific set of instructions, put pieces together sequentially and then showcase a collection of virtually identical products.

While I can't pretend to know a whole lot about engineering, I am pretty confident that if the discipline were focused on building from instruction booklets, Chris Hadfield wouldn't have spent the last 6 months in space. As Dr. David Perkins' mentions in Making Learning Whole, kids don't learn to play the game if all they ever get are the pieces...

On Light, Shadows and Experience

Co-authored by Jenna Callaghan
Cross-posted on the Calgary Science School's Connect!

We began a recent investigation into Light and Shadows in Grade 4 by posing the question “What is Light?” to our students. Before beginning the conversation, we reminded students that the world is not nearly as concrete or easily-understood as over-simplified statements of "fact" might often imply. We talked about how scientists are by nature inquisitive, always open to possibility and a reinvention of old ideas. We suggested that throughout our inquiry, they too might have the potential to share a completely new perspective, contribute to making new discoveries and either support or disprove current thoughts. With two of us in the classroom, we were able to capture some of our students’ opening ideas about 'Light' and have embedded them below.

How to Love a Plant

Amy Park and Deirdre Bailey

Earlier this year we had a pretty cool opportunity to connect with Mount Royal University professor Dr. David Bird to co-present on Plant Growth and Changes for the Calgary Science Network. We were most eager for an opportunity to ask Dr. Bird what one one thing he wished his university students came in with that we might be able to foster in elementary school. His answer was unhesitatingly curiosity. He wished his students arrived at university with a desire, confidence and ability to ask scientific questions. Overwhelmingly, many of them arrived reluctant to explore, preferring instead to wait for instructions on what to think or how to deliver in order to "pass the course".

We were excited to be able to share the following (recently completed) video with Dr. Bird and to have a conversation about the kind of thinking we tried to cultivate in our students throughout the process. Having effectively guided them toward deeper understanding of scientific research earlier in the year with our Rotten Tomatoes Decomposition Lab, our inquiry into plant growth invited students' to use their experience with the 'Game of Science' to develop their own questions this time around. They were free to choose how to structure and represent their research autonomously, based on their previous experience.

The results were messy and in some cases, disorganized. Maintaining controlled conditions was difficult, keeping outdoor plants alive in May was a challenge. Many students discovered on their own why quantitative observations are typically separated from qualitative data, how organizing information makes analyses much simpler, and which variables should be most carefully observed when documenting plant growth. Though some conclusions were surprising or skewed by human error, the real value was that our students wrapped up these experiments with an insatiable desire to discover more about plants, undeterred by the awareness that everything might fail.

Google just keeps killing it...

Deirdre Bailey

I had a conversation with a teacher today which prompted this post. It was similar to conversations I'd had in the past about twitter, its advantages and how it has been one of the most valuable learning tools for me as I continue to inquire into teaching and learning. I find it impossible to contain my enthusiasm for how twitter has revolutionized my information consumption as I tailor it to my interests and engage in dialogue deepening my understanding. My enthusiasm for twitter might be eclipsed only by my enthusiasm for google docs. I continue to be overwhelmingly excited by the facility with which google docs allows me to  guide student collaboration, research and writing while tracking their progress, providing feedback and involving parents. It has also made assessment a total breeze.

I work at an innovative and creative institution. Perhaps it is because of the freedom we have to explore possibilities that we are often unaware of the depth to many of the simplest resources that are available. It is also without a doubt hard to be constantly adapting one's practice to ever-updating technology applications. Certainly, in this day and age, the sheer volume of resources available in education can be overwhelming. Navigating options and rating their relative value is always intimidating, particularly on the heels of a full 7 hours in front of students. But google docs is so worth it and I really am that sure. And while my presence on twitter often gives me the impression that all educators are connected, deeply familiar with technological resources and employing them in their every day practice; it occurred to me today that this might not be representative of all cases. As I continue to stumble upon features in google docs that make my job incredibly easier, I thought it might be valuable to share the simple features I have discovered and am so thankful for. This is either a biased and likely limited overview of how GDocs has been used in our classroom this year, for those who have not had the time or opportunity to explore, or it is a simple plug for the brilliance of google documents and their value in the classroom.
                                                                                                    

For our most recent science lab data collection. We used GDocs to create spreadsheets...


...which we linked to our google site 


and shared these with student groups who edited in their own colours, uploaded photos, and separated their qualitative data from their quantitative data by inserting additional sheets

Qualitative Sample


Quantitative Sample


Students used the functions feature in google spreadsheets to verify their calculations:


 They were able to graph various data using the insert chart function


We used google forms to create a survey allowing students to provide feedback on others' work...



...which transferred their feedback to a sortable spreadsheet which we were able to cut and paste into their original Science Lab spreadsheets.


The second time around, we have had students create and share their own google documents to design plant growth experiments.


We had them insert a link from this google doc to a spreadsheet in which they would track their data...


We have been able to provide feedback on particular sections of their work using the new comments feature which allows us to send them notifications and which allows them to reply and/or resolve* the comment.
*Resolving a comment removes it from the document but does not remove it from the discussion stream.


We have also been SO grateful for the revision history function which allows us to see every edit that has been made to the document since creation including accidental deletions and who has made each change and when... Furthermore, previous revisions can be restored!! Pure genius.


Google docs can be edited from any computer which makes working from home simple. It is so easy to hold kids accountable for the work they do. It takes collaboration to a whole new level and it is only getting better. I should mention that our students are only 9 and 10 years old and they have had no trouble navigating these features through their own google accounts. I can't even imagine what the future might hold for a creative mind provided with these tools. Please comment if I've missed anything particularly useful or obvious. It would make my day.

Students into Scientists

Deirdre Bailey and Amy Park

It began with a conversation on how best to develop deep understanding of biological cycles. When we considered simply slicing fruit and vegetables in half and leaving them out in the open to observe the resulting changes, we never anticipated the smells, the new life, or the learning that would ensue.


The suggestion that we use Google Docs to facilitate collaboration and data management through the scientific process provided an excellent opportunity for introducing students to the incredible value of  facilitating collaborative research and documentation through technology. Have a look at our students' work, linked directly to our classes' Science Lab Website.


Although our decomposed specimens are now carefully buried in soil, the memory of the experiment is alive and well among our grade 4 students.  From Day 1 to Day 12, these young scientists were engaged, excited, and passionate about their discoveries. Throughout the process, students developed deep understanding of decomposition, the scientific process, collaboration, problem solving, data analysis, and so much more.

The following video outlines the entire process and the amazing learning that resulted.

Waste and Our World Movie Project

Deirdre Bailey and Amy Park
Cross-posted on Calgary Science School's Connect!

Our Grade 4 classes have spent the past three months inquiring into the topic of "Waste and Our World" with the goal of developing an appreciation and understanding of their roles and responsibilities as global citizens of this environmentally fragile and increasingly endangered planet. We had hoped that our inquiry would help students feel empowered to sustain environmentally conscious action as part of their everyday lives. 

Our first mission was to collect garbage from the school ground. Students were shocked to discover that we had collected over 4lbs of lunch-related waste in one day and that this amount was repeated by the following class the next day! This activity made it clear that action for the environment was needed and could have a very real effect in our immediate community. As a group, we concluded that one minute public service announcements highlighting a need for change in our daily practices would be the best way to inform our school peers and inspire action. 

In order to build understanding and knowledge prior to designing their PSA's, students worked through a variety of tasks which included:
  • creating a decomposition timeline using human waste collected in the immediate area
  • discussing the composition of various human waste items and the factors affecting their breakdown
  • digitally documenting human waste samples from our school grounds
  • completing a retrieval chart with hypotheses on their specimen's origin and ultimate destination
Once students had a good understanding of the impact our human waste can have on the environment, we turned our attention to natural waste and consideration of how our natural world discards, reuses and recycles. As part of our exploration we:

Armed with a new understanding of how human and natural waste fit in our world, students watched some exemplar PSAs and advertisements aimed at communicating powerful environmental messages. We then worked together to build a rubric outlining what exemplary work might look like!

FInally, students supplemented what they had learned with the info on their retrieval sheets and internet resources to create one-page storyboards communicating their ideas effectively and concisely. Once their storyboards had been approved, they worked in collaborative groups to add voice to their own images creating short movies highlighting differences between human and natural waste and the impact they both have on our world. 

Students had the opportunity to showcase their first products in front of their classmates, after which they were provided with constructive feedback that was related to the rubric and based on the work. Throughout this process, students learned how to give feedback as well as how to receive it, and use it to improve. They were able to learn by reflecting on the work they and their classmates had created, and were then given an opportunity to use what they'd learned to refine their final movie project.

Here's an overview of the process:


Of the 22 projects, our group selected the best of the best to represent our learning and the message we hope to convey. Please help us get the word out by commenting below, sharing your feedback and your ideas on how we might be able to share these with a broader audience. Thanks for listening!

These kids get it

Deirdre Bailey

Today was amazing for a number of reasons. We finished our decomposition lab this morning. It had been an enlightening few weeks of learning what becomes of a perishable food, halved and left in the open for three weeks. Some awesome things happen to rotting fruit after it starts to smell, not least of which are fluid loss and bacteria growth. This morning, the tomato had given birth to a new family of fruit flies, all of whom remained happily trapped under the wrapping as our young scientists whooped victoriously while pressing their faces to the creeping mass of molding vegetable.


As today was the last day of our lab, we were burying our specimens in dirt with plans to test soil content and plant growth in the New Year. Most students were happy to put an end to an experiment that was becoming increasingly hard on the stomach, however one group in particular stood out as they proceeded solemnly to the dirt pile with their specimen, chanting the name "Alfred" in melancholic tones. "Aaaaalfreeed, life won't be the same without your stink... Aaaaalfreeeed, you taught us a lot about mould.... Aaaaalreed, we are going to bury you so you can grow a plant..." Alfred was their cucumber.

When I think back to the things I remember from Grade 4, I struggle to recall anything memorable outside of field experiences, Christmas holidays and family trips to Ireland. I imagine however, that if I had spent two weeks watching Alfred shrink, stink, and give birth to fruit flies, that I would remember Alfred. As adults, we seem to spend a tremendous amount of time discussing, warning and lecturing without experiencing and we forget so easily that our most powerful inspirations to date will have almost exclusively resulted from actual emotional experiences.

After lunch we had a presenter come and talk about endangered species in North America, specifically wolves. She asked the kids a number of questions which they were eager to answer, one of which was  about why maintaining the wolf population was of benefit to trees. Thirty plus hands went up.

"Because the nutrients in their poop help build rich soil for plant growth..." 

"Because they eat animals which would destroy the trees in larger quantities..."

"Because they sometimes eat plants and poop the seeds which helps distribute the growth..." 

Three months exploring the Weaselhead and connecting online in order to develop meaningful videos highlighting local natural waste and its place in our ecosystem had paid off. Natural organisms have a place in the wild, these kids had seen it.  "Wow, you guys really get it" was our presenter's response. "I have this conversation all the time with adults and it is hard for them to understand how wolves are connected to the trees."

"EVERYthing is connected to the trees!" was one indignant reply. Followed by: 

"..those adults, you have to explain a lot of things to them, there's so much they just don't understand..."

We learned a lot about native species in Alberta in 45 minutes. We learned a worrying amount about what our government says they're doing to protect them, as even to 9 year olds, many of their policies appear outdated and nonsensical. I gave the students sticky notes at the end of the presentation to jot ideas and questions about our current Endangered Species Act, what's working and what we should change. One student kept coming back for more notes... "Three's the limit right Mrs. Bailey? I can only have three ideas?" Who told this kid and at what point in his life that he could only have three ideas? He wants to write to the government on behalf of every one of the 13 male sage grouse left in our province. Then he wants to tell them that shooting wolves won't save cariboo, that Little Red Riding Hood was a liar, that wolves aren't the bad guys. He also wants to tell them to forget about the oil in the ground on the Blood Tribe land and just re-introduce the Swift Fox population the way they'd planned in 1973 and that they should be ashamed they've waited so long. He's got classmates on board.

Adults should remember that it's that simple. Kids are already curious and creative. They want to explore things and find out what's happening. Nothing about who they are is average, obedient or passive. All that is left to us, is to foster an awareness of the possibilities that surround them, to allow them to explore and then to get out of the way. Let them ask questions, make decisions, be different. There's more to their futures than resigned consumption and obedience.
