Mr. Mak's Grade 7 Science Website

*Quick reminder that our unit test will be on Tuesday November 7, 2017 (Ecosystems, Photosynthesis, Water Cycle, Carbon Cycle, Microscopes, Scientific Method). I will post some study hints next week.... *Rotocopters/Scientific Method Lab Report is due to Mr. Mak by Wednesday, November 8, 2017 Rotocopter Mini-Lab Report – Introduction to Using the Scientific Method 1.      Briefly explain what the Scientific Method is. 2.      List the key steps in the Scientific Method. 3.      Write out the Question or Problem you will be investigating. 4.      Write down the Hypothesis/Prediction of what you think will happen for each of your new rotocopter designs. *Include one hypothesis per Rotocopter design (i.e. - you need two hypotheses) 5.      List all Materials you will need. 6a)      Write out the Procedure you will follow, in numbered steps. 6b) Explain what will your Independent Variable be? The one YOU change (“I” change) 6c) Exp

*If you did not complete these in class, you may sign out the "mini-textbook" for one evening *Due to Mr. Mak by Tuesday, Oct 31! 1) Read 36-37, answer page 38 #1,2 2) Read 38-39, answer page 40 #1,2,3, pg. 43 #4,5 3) Read 52-52, answer page 54 #1,2,3 4) Read page 55, then match the animal(organism) to the appropriate Biome Water Cycle Videos: https://www.youtube.com/watch?v=al-do-HGuIk https://www.youtube.com/watch?v=jFjI6y46QRk *For any budding Scientists at JSB, there is a FREE weekly lecture I highly recommend checking out with your family.

Producer, Consumer or Decomposer? Decomposers video: https://www.youtube.com/watch?v=Z6V0a_7N1Mw Try the Producers, Consumers and Decomposers Game, as well as the Food Chains Game for some fun review of concepts! http://www.sheppardsoftware.com/science.htm If you're interested in some of what you've seen the Grade 8's learning about, try the games linked below! http://www.sheppardsoftware.com/health/anatomy/cell/index.htm What would "Google" do if it could redesign part of Toronto's waterfront?

Learning Goals: -To understand what invasive species are -To analyze the impact of invasive species on food webs, chains and pyramids worldwide https://www.youtube.com/watch?v=spTWwqVP_2s Mini-Presentation Procedure and Expectations: 1. Choose an invasive species (using the websites below, or your own research) http://www.earthrangers.com/wildwire/top-10/ten-of-the-worlds-most-invasive-species/ http://www.cbc.ca/news/technology/10-invasive-species-threatening-canadian-habitats-1.950951 2. Prepare a short, well-reheased, 1-2 minute presentation on the invasive species of your choice. Use Google slides, Powerpoint or Prezi (see Mr. Mak if you need any help with these programs) 3. Include: -Where the species originally lives and where the species has migrated to (with a map) -Background information about the organism: habitat, is it a producer, consumer or decomposer? is it a scavenger? is it a primary, secondary or tertiary consumer? is it an apex predator? int

https://www.youtube.com/watch?v=hLq2datPo5M 1.      In your own words, explain what a food chain is. 2.      Where does all energy in the Earth’s food chains come from? 3.      What type of organism must every food chain start with? 4.      In a food chain, what is the name given to any organism that directly eats plants? 5.      Explain, in your own words, what a secondary consumer is? 6.      Do you think a secondary consumer can be a herbivore? Explain why or why not. 7.      Make and label a quick sketch for the plant, rabbit and fox food chain described by the video. Include the labels producer, primary consumer, secondary consumer, herbivore, and carnivore. Use arrows to show the flow of energy between organisms. 8.      What percentage of energy is passed from level to level in a food chain? 9.      Explain, in your own words, what a tertiary consumer is. 10. Explain, in your own words, what an apex predator is. Include three or more examples of t

*Please make sure you have completed all work (ecosystems questions, characteristics of living things, and photosynthesis questions by Tuesday October 10. Be sure to SHOW Mr. Mak when you are done. If you are absent for athletics or illness, it is your responsibility to use the website to catch up. Learning Goals 1) Explain what photosynthesis is and why it is important for life on Earth. 2) Know and be able to explain the "word equation" for photosynthesis. 3) Give a simple explanation of how and where photosynthesis takes place inside plant cells. The middle of the video below show what cells undergoing photosynthesis actually look like: https://www.pbslearningmedia.org/resource/tdc02.sci.life.stru.photosynth/photosynthesis/#.WdOvekt97rc Bonus: More advanced video for those interested https://www.youtube.com/watch?v=HWqVgpAmf5I Photosynthesis Questions (Use the Ted Ed video to complete these) https://www.youtube.com/watch?v=eo5XndJaz-Y What are the

*Ecosystems questions posted last week must be complete by Wednesday October 5 *Needs of Living Things questions must be complete by Wednesday October 5 (if you need to sign out the Ecosystem mini-textbooks for ONE EVENING ONLY please speak to Mr. Mak) Complete the questions below using the "Ecosystems mini-textbook" - pg. #11-13  Needs of Living Things 1. What are the six needs of all living things? 2. What fraction of a human body is made of water? 3. List six things living organisms need energy to accomplish. 4.
