Exploring Physical and Chemical Properties in the Lab

The video tutorial covers various lab stations focusing on physical and chemical properties. Students observe and classify properties such as color, rust, malleability, ductility, viscosity, reactivity, states of matter, solubility, and density. Each station involves specific tasks and questions to enhance understanding of these properties.

Which of the following substances is NOT listed in the color station?

• Sulfur

• Ammonium dichromate

• Salt

• Iron

Why might color be a useful property to describe and identify a substance?

• It is a chemical property.

• It can be easily observed and compared.

• It is always unique to each substance.

• It changes frequently.

What is the appearance of a rusted iron nail compared to an iron nail?

• Flexible

• Transparent

• Dull and rough

• Shiny and smooth

How is the ability to rust classified?

• As a physical property

• As a chemical property

• As neither a physical nor chemical property

• As both a physical and chemical property

What are the properties of copper discussed in the malleability and ductility station?

• Soft and flexible

• Malleable and ductile

• Rigid and inflexible

• Brittle and hard

Which liquid property is being measured by dropping a fish line in a graduated cylinder?

• Solubility

• Viscosity

• Reactivity

• Density

What should you observe when calcium reacts with water?

• No reaction

• Temperature decrease

• Formation of bubbles

• Color change
