Grade 5: What are the 3 types of mixtures Grade 6: Name the properties of air
Grade 5: solid-solid, solid-liquid, liquid-liquid Grade 6: air occupies space, air has mass, air exerts pressure
100
Grade 5: How would you separate a mixture of sand and rocks? Grade 6: According to Bernoulli's principal goes fast moving air have low or high pressure?
Grade 5: Use a sieve Grade 6: low pressure

Grade 5: What type of change happens when ice melts? Grade 6: How do birds get lift?
Grade 5: physical change Grade 6: Use their large pectoral muscles that generate power to flap the wings.

Grade 5: How do you make crystals? Grade 6: What is streamlining?
Grade 5: mix equal amounts of bluing, ammonia, water and salt and place a charcoal brick in the solution and wait Grade 6: Shaping of an object so that a gas or liquid will move easily around it.
100
Grade 5: What's an acid? Grade 6: True or False, air is made up entirely of oxygen?
Grade 5: Something that tastes sour like lemons or oranges. It turns red litmus paper red. Grade 6: False, there are a ton of chemicals. Carbon dioxide, argon, nitrogen, etc.

Grade 5: What types of mixture is pizza? Grade 6: How do you prove that air has mass?
Grade 5: solid-liquid Grade 6: balance experiment
200
Grade 5: How would you separate a mixture of salt and water? Grade 6: According to Bernoulli's principle does slow moving air have low or high pressure?
Grade 5: evaportation Grade 6: high pressure
200
Grade 5: How do we know that irreversible change occurred? Grade 6: What happens to an airplane, if the lift becomes greater than the mass?
Grade 5: A chemical reaction occurred. We can tell that a chemical reaction occurred, if heat was emitted, a gas is emitted, a precipitate is formed, or colour change occured. Grade 6: The plane goes up
200
Grade 5: What are the two special properties that water has, that no other liquid has? Grade 6: Why does a crumpled parachute fall to the ground faster than and flat one?
Grade 5: cohesion and surface tension Grade 6: because it has less surface area
200
Grade 5: What colour does blue litmus paper turn when it touches a base? Grade 6: What chemical do we need in order for a flame to burn?
Grade 5: blue Grade 6: oxygen
300
Grade 5: What type of mixture is lemonade? Grade 6: How can we prove that air occupies space?
Grade 5: solids-liquid (lemons, sugar, ice, water) Grade 6: blowing up the balloon in the bottle
300
Grade 5: How would you separate a mixture of sawdust, sand and stones? Grade 6: What force does Bernoulli's Principle explain?
Grade 5: Pick out the rocks, place the mixture in water, skim the sawdust off the top. Grade 6: lift
300
Grade 5: Is baking a cake a reversible or irreversible change? Grade 6: What happens to a plane if the thrust becomes greater than the drag?
Grade 5: Irreversible Grade 6: Goes faster
300
Grade 5: How is carbon dioxide different than air Grade 6: How could a skier reduce drag?
Open ended responses
300
Grade 5: What colour does blue litmus paper turn when it's placed in an acid? Grade 6: How can we make carbon dioxide
Grade 5: red Grade 6: Just breath out or mix vinegar and baking soda together
400
Grade 5: What type of mixture is oil and vinegar dressing? Grade 6: How can we prove that air exerts pressure?
Grade 5: liquid-liquid Grade 6: newspaper over the ruler experiment
400
Grade 5: How would you separate a mixture of sand and salt? Grade 6: If I blow air between two hanging balls, what will happen and why?
Grade 5: Place the mixture in water, let the salt dissolve in the water, the remove the sand from the bottom of the container, then finally allow the water to evaporate leaving the salt behind. Grade 6: The balls will move in and hit each other, because the fast moving air between the balls will be low pressure, which will cause the high pressure air surrounding the balls to move, and push the balls together.
400
Grade 5: What type of change is making crystals? Grade 6: What happens to a plane if lift, mass, thrust, and drag become equal?
Grade 5: Reversible Grade 6: The plane would hover
400
Grade 5: How do crystals form? Grade 6: How can swimmers reduce drag?
Grade 5: By having a super saturated, solution, when the liquid evaporates, the salt builds up the charcoal in crystal form. Grade 6: Clothing
400
Grade 5: What happens to red litmus paper when it touches a base? Grade 6: What happens to a flame when it is touched by carbon dioxide?
Grade 5: Turns blue Grade 6: Goes out
500
Grade 5: What kind of mixture is tea and milk? Grade 6: How can you prove that air is fluid like?
Grade 5: liquid-liquid Grade 6: balloon and bottles experiment
500
Grade 5: How would you separate a mixtures or iron fillings, sawdust, sand and salt? Grade 6: What happens if you blow air between two cans?
Grade 5: Use a magnet to remove the iron fillings, use water to skim off the sawdust, let the salt evaporate dissolve into the water, remove the sand, let the water evaporate. Grade 6: Due to a difference in pressure the cans would move to get closer together.
500
Grade 5: What type of change frying an egg? Grade 6: What happens to a plane if the thrust becomes less than the drag?
Grade 5: irreversible Grade 6: plane goes down
500
Grade 5: Why did crystals form on the side of the cup? Grade 6: How can cyclists reduce drag?
Grade 5: Because there was solution on the side of the cup. Grade 6: clothing, body posture, helmet
