Below are the resources we went over in class when learning about the periodic table. Play around with the simulator at the bottom of the post if you want to learn more!

Some Key Concepts About Elements and their Atoms

• Atoms are made of extremely tiny particles called protons, neutrons, and electrons.
• Protons and neutrons are in the center of the atom, making up the nucleus.
• Electrons surround the nucleus.
• Protons have a positive charge.
• Electrons have a negative charge.
• The charge on the proton and electron are exactly the same size but opposite.
• Neutrons have no charge.
• Since opposite charges attract, protons and electrons attract each other.

Build an Atom Simulator

Build an Atom Simulator student assignment (Due Wed. May 6th)

Here is the presentation we went over together on the Particle Theory. You can refer back to it when completing future at home labs.

Visit the following website (https://www.proprofs.com/quiz-school/story.php?title=particle-theory) and complete the quick quiz on the Particle Theory.

Dissolving Rates

Here are the links to the at home labs for this unit

Marks are based on the Scientific Method in this Lab Rubric

Lab # 1 – Matter – Due March 31, 2020

Lab # 2 – Dissolving Rates – Due April 3, 2020

Please watch the two videos below and then answer the questions at the bottom of the post in a google doc. Please share your doc with me j.ray@theojcs.ca and have your answers with you when we meet during Monday’s live session. I hope everyone is doing well, and there is no baby update except that our bags are packed and ready at any point!

Before you answer the following questions, please create a folder in your google drive called ‘Science’ to put all of your docs/resources for Science in one spot and keep you organized.

Questions – submit #1-4 to me (Challenge question is an extra and not mandatory)

1. a) When getting a bath ready, a bath bomb and water is used. Identify which is the solute and solvent.b) Will the bath contain a solution or a mechanical mixture? Explain why?
2. How is a solution different from a mechanical mixture? Include the terms homogeneous and heterogeneous in your answer.
3. Which of the following is a solution, and which is a mechanical mixture? Explain your choices.

a) wood          b) tap water           c) orange juice          d) loonie coin

4. Give an example of each of the following kinds of solutions, other than those mentioned in the video.

a) a liquid in a liquid              b) a solid in a solid                c) a solid in a liquid

Challenge Question

Sea water contains perhaps the largest number of dissolved solids. Gold, for example, is found dissolved in sea water. It has been estimated that if 1 km³ of sea water is evaporated, 0.004 tonnes of gold can be recovered. What is the value of the gold in 1 km³ of sea water? (You can check online to see what the current price of gold is. Gold is often measure in troy ounces, and one troy ounce = 31.1 g)

Congratulations to the middle school students for successfully accomplishing their projects this year! I heard so many positive and amazing comments from parents, teachers, and this year’s judges. They were impressed with the level of research, the creative engineering, and imaginative presentations that YOU designed and created. Outstanding effort, I am very proud of the work you put into those projects! Here are the results from Innovation Day judging as well as the video we saw as part of the assembly. I can only imagine what creative projects you will dream up for next year. Well done!

Innovation Day is finally upon us! It feels like forever ago when students began thinking about their passions, ideating different topics, creating pitches, and starting the journey of their personalized learning.  As the teacher, I can’t tell you how excited I am to see all of the hard work put into researching their topics, the creative problem solving needed to engineer products, and the creative story they will tell, all come together for next week’s presentations.
