Grade 6 Jumps into Classification

For our second and third lessons on “Diversity of Life”, students have been learning about how the myriad of living things on this planet has developed a need for classification. Students have been learning about the levels of classification of living things and practicing building a taxonomic key as if they were biologists.

Students practice classifying organisms and identifying the scientific name (genus and species)

Grade 7 Learns about the Properties of Metals

The seventh graders have been learning about metals and how the periodic table of elements is organized. Here is one of the resources that the class has been using that can found on our moodle page:

On Wednesday, the students performed some experiments on Copper and Carbon to determine which physical properties each of them had with regards to ductility, flexibility, electrical and thermal conductivity. This was our first individual lab, although students worked in groups. The basis of the lab is how the properties of materials determine their use.

In the coming weeks, we’ll be learning about the periodic table of the elements and our guiding question:

“How is the periodic table of the elements organized?”

News from The Science Classroom-Atoms, Life, Powerschool and Literacy

Areas of Focus

The sixth and seventh graders have moved on from the scientific method and have started to investigate atomic theory and what it means to be alive. Seventh graders have started investigating this by differentiating their own interests by either building models of atoms to understand atomic theory, or researching past atomic models such as Rutherford’s, Bohr’s, Dalton’s or Thomson’s model. The sixth graders have been learning about what it means it means to be “alive” by learning about what all living things have in common regardless of their shape or size.

 

 

Checking in with “Powerschool”

A parent asked me a great question at back to school night: “How often should I check Powerschool?”. Which is a great question. I recommend checking powerschool once every two weeks to see your child’s progress, however, if you sense your child is struggling, I would check every week. I have a very good grasp of our curriculum and try to make our learning activities and curriculum as transparent as possible. I encourage parents and students to click on assignment descriptions for more information.

Clicking on any assignment's description will show you an overview of the learning activity, essential questions that guided the question, learning standards, and assessment type.

Grade Distortion-Common Worries Early in the Semester

Early on in the semester with only a few assignments, there is a lot of “grade distortion”. Grade distortion is caused by one or two low grades on an assignment and the difference of one or two points may cause a student’s grade to be very low. I assess assignments at time of submission, but if they are incomplete at the time of submission, I usually indicate this as a note within the assignment on powerschool and encourage students to resubmit this. Students also need some help navigating this within powerschool and usually see their academic standing rise after completing their “best” work.

Clicking on the number reveals:"I think you're off to a good start, but I disagree with your conclusions. You said the beans got smaller, but bean number 3 got quite a bit longer. So how can you make the conclusion that you did? Also, you said the beans got smaller, but you said in the volume question that the volumes got bigger! Be sure that you actually look at the data that you collect and make conclusions with it rather than one errant measurement. Finally, your sentences are only 1 sentence without much substance. Care to resubmit?"

Clicking on the number “9″ above reveals:”I think you’re off to a good start, but I disagree with your conclusions. You said the beans got smaller, but bean number 3 got quite a bit longer. So how can you make the conclusion that you did? Also, you said the beans got smaller, but you said in the volume question that the volumes got bigger! Be sure that you actually look at the data that you collect and make conclusions with it rather than one errant measurement. Finally, your sentences are only 1 sentence without much substance. Care to resubmit?”

 

I also send mass emails out to students asking them to submit their best work and encourage them to make amendments, but having a parent walk them through accessing this information is the first step towards having the child do it independently. Some parents have expressed concerned about their child’s academics by merely looking at the letter grade and not clicking for more specific information about assignments. If a student is struggling, it’s usually due to missing or incomplete work. Please assist your child with locating this information. As most assignments are on Google docs, they can just send me the link afterwards or come in during the morning or during tutorial time on Wednesday. Sixth graders usually need a lot of support to develop these “student skills” but they do develop in time with a good support network.

Formative assessments (day to day work) are reported for reference so a student knows their strengths and weaknesses when they go back to review previous work.

Literacy Activities

One of our whole-school initiative is on improving literacy (reading and writing) and because of this, you’ll see more language arts activities permeate into all classes. I firmly believe that improving writing is a task not done by merely the language arts teacher, but by all teachers. Expect to see argumentative and persuasive writing permeate into science and quick formative activities like “Tell a Friend” as you see below:

If you have any questions about any of the above, feel free to contact me by email. Have a great weekend!

Grade 7 Maps Water Quality of Ho Chi Minh City

As part of our final application of skills and knowledge in our unit on “Watersheds” the students have collected water around Ho Chi Minh City, tested it, and analyzed it’s health.

This has been a really exciting project made possible by Google maps and not only that, some classrooms around the world have expressed interest in joining us next year to collect and monitor water near school districts around the world. Although I have worked with teachers from different locations before, this endeavor is shaping up to be the largest collaboration and long-term data collection project of which I’ve ever been involved. Our base-line of data collection this year will serve as a starting point to show long term changes of the earth’s water quality over time.

As a final note, I want to thank all parents for their support in the science classroom this year. Every child has shown a distinct interest in at least one area of science and has grown in so many ways. I’m encouraging them to “Stay Curious” this summer!

Sincerely,

Sixth Grade Creates Digital Stories to Learn about Earth’s History

The sixth graders have just finished presenting digital stories for our final project “Inside Earth”. Our study of earth and it’s history has taken us on a journey through many fascinating topics such as:

  • Earth’s Interior
  • The Rock Cycle
  • Igneous Rocks
  • Sedimentary Rocks
  • Metamorphic Rocks
  • Evolution of Life
  • Law of Superposition
  • What Causes Earthquakes?
  • Continental Drift

For our final project, students have chosen of these topics to investigate more in depth and produce a digital story to help teach it to others. Digital stories combine video and images with audio narration and sound effects to tell a more memorable, compelling story. The students have their work on their blogs which you can access at this link. Below are some class favorites.

To all my the parents of my students, thanks so much for your support this year, working with your children has been such a pleasure!

Grade 7 Learns about Watersheds

Grade 7 has been learning about watersheds. Below is our first mapping activity wherein students had to map a watershed from their home environment by indicating:

  • Divides: Mountain, Ridges, Hills
  • Tributaries: Streams that flow into larger rivers

Google maps will come in handy for our study and allow us to add multiple layers of information for analysis.

Grade 6 Builds a Distillation Apparatus

The sixth graders have just finished building a distillation apparatus for our unit on chemistry. I’ve documented the process in a movie below. The students have uploaded their work to their blogs for reference.

Have a great spring break!

 

Students: Write a Short Paragraph on the Following:

  1. Do you think your device worked well enough to be considered for mass scale production? (Give examples)
  2. Do you think it’s easier to purify water, or to keep it clean? Why?
  3. How can countries grow and prosper without degrading the environment?
  4. How has this project made you think about water and our resources?
