Matter Basics
What we call an object or substance that has mass and volume.
What is matter?
The word that means the observable or measurable characteristic of an object?
What is a property?
When ice melts to liquid, what happens to the total amount of matter?
What is conserved (stays the same)?
The tiny bits of a substance that reach your nose and cause smell?
What are gas particles?
The term for how well heat moves through a material.
What is thermal conductivity?
The name we give to the tiny pieces that make up matter
What are particles?
The type of property that uses the senses and words rather than numbers (examples: color, smell)
What is a qualitative property?
The name of the process when particles at the surface of a liquid escape into the air as gas.
What is evaporation?
The smell strongest near a cup of peppermint oil.
What is because the concentration of peppermint particles is highest near the cup, so more particles enter each breath (higher concentration →stronger smell)
The metal from our lesson that had the highest thermal conductivity.
What is copper?
The term for “how much stuff is inside an object,” measured in grams?
What is mass?
The type of property that uses numbers and units (examples: mass in g, volume in cm³)
What is quantitative property?
In melting or dissolving investigations, the quantity that students measure with an electronic scale (to test conservation of matter) is called this.
What is mass? or What is weight?
Name two classroom factors that make a smell spread faster.
What is higher temperature (increases evaporation) and air currents (people moving, vents, open windows)?
In the “Too Hot to Handle?” activity, the material that had the lowest conductivity.
What is wood?
The name for “how tightly the stuff is packed into a space,” calculated as mass ÷ volume?
What is density?
The property that measures how well heat energy passes through a material.
What is thermal conductivity?
If dissolved salt reforms as crystals after evaporation, what key idea does that support?
What is conservation of matter (the salt was still present)?
For a student model of peppermint smell, list four elements that you must draw or label.
What are a container with liquid particles; zoom‑in bubble showing evaporation at the surface; gas particles spreading with arrows (diffusion) and labeled high/low concentration; a nose receiving particles (labels: evaporation, diffusion, concentration)?
Many frying pans have a copper bottom but a wooden or plastic handle. Explain why(short answer)
What is copper bottom conducts heat well to cook evenly; wooden/plastic handle is low conductivity so it stays cooler and is safer to hold?
This means to separate into smaller pieces?
What is subdivided?
The property that describes how well light or sound bounces off a surface.
What is reflectivity?
3 parts
1-In our NY state investigation "What's in a bag?" was a new substance formed?
2-Explain why or why not?
3-Was mass (matter) conserved?
What is yes a new substance was formed because the alka seltzer tablet disappeared and a gas was formed?
What is yes mass was conserved because even with a chemical change mass is conserved?
The process by which gas particles spread from areas of high concentration to low concentration.
What is diffusion?
Order these metals from highest to lowest thermal conductivity: brass, stainless steel, copper, aluminum.
What are copper, aluminum, brass, and stainless steel?
