Station 1: Tea BagsDESIGN – How to accomplish this activity?1.Remove the staple, string, and label from the bag of tea.2.If your bag of tea is not open on its ends, cut both ends off and empty out the tea into the trash.3.Unfold the bag of tea so that it is completely straight.4.Use your fingers to open the bag of tea. You should end up with a shape resembling a cylinder.5.Stand the cylinder on one end on a flat, non-flammable surface. A dinner plate works perfectly.6.Using a lighter or match, ignite the top of the cylinder.7.Watch the flame travel down from the top of the cylinder until…Liftoff! The bag of tea takes off into the air like a rocket.Question: How can density explain floating tea bags?Observations: Quantitative QualitativeClaim: A statement that answers the original questionEvidence: Scientific data that supports the claim. Can come from an investigation or other sources such as observations, reading material, archived data, or other sources. Often includes Analysis of the data and observations collected during the investigation. Reasoning/Justification: Links the claim and evidence. Shows why the data counts as evidence to support the claim, using appropriate scientific principles. Station 2: Mixing Fluids in Graduated CylindersDESIGN – How to accomplish this activity?Ask students what the total volume will be when fluid A (300 mL) is mixed with fluid B (300 mL). Carefully pour the fluids found in the 600 mL beakers labelled A and B into the 1000 mL graduated cylinder. Question: Where did the matter go? Observations: Quantitative QualitativeClaim: A statement that answers the original questionEvidence: Scientific data that supports the claim. Can come from an investigation or other sources such as observations, reading material, archived data, or other sources. Often includes Analysis of the data and observations collected during the investigation. Reasoning/Justification: Links the claim and evidence. Shows why the data counts as evidence to support the claim, using appropriate scientific principles. Station 3: Mixing Fluids in Volumetric FlasksDESIGN – How to accomplish this activity?Ask students what the total volume will be when fluid A (1000 mL) is mixed with fluid B (1000 mL) Carefully pour the fluids found in the 1000 mL volumetric flasks labelled A and B into the 2000 mL volumetric flask. Question: Where did the extra matter come from? Observations: Quantitative QualitativeClaim: A statement that answers the original questionEvidence: Scientific data that supports the claim. Can come from an investigation or other sources such as observations, reading material, archived data, or other sources. Often includes Analysis of the data and observations collected during the investigation. Reasoning/Justification: Links the claim and evidence. Shows why the data counts as evidence to support the claim, using appropriate scientific principles. Station 4: The Rising… DESIGN – How to accomplish this activity?Place a layer of water in a small pan or dinner plate, (food colouring can be added allowing for the effect become more noticeable).Place a candle in the middle of the small pan or plate.Light the candle and place the glass jar over top of the candle, sealing the candle on top with the glass jar and on the bottom with the layer of waterObserve the candle as it burns within the class jar.The effect may take a moment to occur – be patient.Question: Why does the fluid rise? Observations: Quantitative QualitativeClaim: A statement that answers the original questionEvidence: Scientific data that supports the claim. Can come from an investigation or other sources such as observations, reading material, archived data, or other sources. Often includes Analysis of the data and observations collected during the investigation. Reasoning/Justification: Links the claim and evidence. Shows why the data counts as evidence to support the claim, using appropriate scientific principles. Station 5: The Eggsexcution? DESIGN – How to accomplish this activity?IMPORTANT: Always wash your hands well with soap and water after handling raw eggs. Some raw eggs contain salmonella bacteria that can make you sick.Fill the large drinking glass about two-thirds (2/3) full with water.Center a pie pan on top of the glass.Place the cardboard tube on the pie plate, positioning it directly over the water.Carefully set the egg on top of the cardboard tube.With your writing hand, smack the edge of the pie pan horizontally. Don't swing up, and don't swing down! It’s important that you hit the pie pan horizontally and use a pretty solid hit, so plan on chasing the plate and tube.Your astonished guests will watch the egg plop nicely into the water. It’s even more fun to watch someone else try to drop the egg.Question: How can gravity save an egg? Observations: Quantitative QualitativeClaim: A statement that answers the original questionEvidence: Scientific data that supports the claim. Can come from an investigation or other sources such as observations, reading material, archived data, or other sources. Often includes Analysis of the data and observations collected during the investigation. Reasoning/Justification: Links the claim and evidence. Shows why the data counts as evidence to support the claim, using appropriate scientific principles. ................
