Mr. Mak's Grade 7 Science Website

Battery-heated Clothing! In partners, students will choose, research and present on a heating or insulating technology of their choice. Presentations will cover some background and historical information, how it works, how it is made (optional) and future variations of the technology (ones being developed or your own creative ideas). Specific topics to cover are expanded upon in the rubric below. Assessment 1 2 3 4 Efficient use of class time. Completion of the task by the assigned due date. Background / History - What it does, what it looks like, when invented, who invented it,  what is it made of, how it has changed over time since it was invented How it works to generate heat or insulate (BONUS SECTION: How it is made) Future variations being developed or your own creative ideas for how it can be modified and improved in the future Presentation to the class: Projecting voice, eye contact, well-rehearsed Format: Clear, well-organzied slides, effective font choice, t

https://www.youtube.com/watch?v=0ki9Kta8g14 The Task: We will be learning about, building and testing simple steam engine boats known as "putt-putt" or "pop-pop" boats.  Step #1 - Watch the video above to get an understanding of how the boat is built. Step #2 - Make a detailed list of all materials needed for the boat's construction as well as tools required to build it. Step #3 - Write down any safety concerns we need to be aware of during the construction process or when operating the boat. Step #4 - Research how the steam engine works and write out an explanation IN YOUR OWN WORDS. Include a simple drawing, if it helps you. (One great resource is Sciencetoymaker.com) Step #5 - Show Mr. Mak steps 2-4 Step #6 - BUILD THE BOAT!!! Step #7 - Test (and improve aesthetics - make it look good!) Bonus Project (if finished early!): Build an elastic band powered wooden boat Look over the designs below and use some elements

The Task: In partners, choose an interesting, classroom-appropriate experiment that involves investigating one or more properties of heat. Once chosen, you will complete a short lab report, which includes: listing materials needed, steps in the procedure and an explanation of the Science behind your experiment (How/Why it works). Each experiment will first be practiced in class, under Mr. Mak's supervision. The following period, it will be demonstrated for the class. Be prepared to explain the "How/Why" it works. Mr. Mak will provide all sources of heat/flame (matches, lighters, hot plate, kettle, blow dryer, etc.), plus any sharps (knives, etc.). DO NOT bring your own to school. Students will bring in all other required materials. Assessment: 1) Use of class time. Completion of the task by the assigned due date. 2) Materials 3) Procedure (This should be detailed enough, that another student can run you experiment based on these instructions). Be sure to include

http://www.ducksters.com/science/heat.php Define, in your own words, what HEAT is. List three units for measuring heat. Clearly explain the difference between heat and temperature. What is the fancy Science word for when heat transfers from one object touching another or mixed with another, and eventually they have the same temperature?  Give one real-world example of equilibrium. Fancy Science word that refers to when heated objects get bigger. Fancy Science word that refers to when objects get smaller as they cool. Briefly explain how expansion and contraction are used in mercury thermometers. Explain what conduction of heat means. List one example of a good conductor. Explain why pots and pans are made of metal. Starting with ice (solid), briefly describe the changes of state that take place as you add more heat.
