Mystery Substances Mini-Investigation

ACTIVITY 1

INSTRUCTIONS

• Stay in your group and work cooperatively.

• Use the cups provided for each test. Make sure to wipe the spoon clean before re-using it.

• When measuring powders, use 1 tablespoon each. When adding liquids, use 1 tablespoon of water or vinegar as instructed.

• Provide 3 pieces of paper to get the powders. Handle the powders carefully — do not taste them. You may use your sense of sight and touch only.

INSTRUCTIONS

• After each test (physical observation, solubility, reaction), record your observations on the worksheet.

• Work quickly but carefully. You have only 20 minutes to finish all steps — observation, testing, and group reflection.

• Form a group with 5 members.

• Write your answer to your notebook.

• Only 1 representative per group will get the materials from the teacher.

• If you have questions, raise your hand — I will come to assist you.

How do chemical changes differ from physical changes?

Poll

What is physical properties?

• characteristics that can be observed or measured without changing the substance's identity

• describe a substance's ability to react with other substances or change into new substances

Poll

is this chemical or physical property?

• Chemical Property

• Physical Property

Poll

What is an intensive physical properties?

• a property that depends on the amount of matter in a sample.

• a property of matter that depends only on the type of matter in a sample and not on the amount.

Aside from the example given, give another example of intensive property

Multiple Choice

What is ductility?

• Ductility refers to a material's resistance to deformation.
• Ductility is the measure of a material's hardness.
• Ductility is the ability to conduct electricity.
• Ductility is the ability of a material to undergo significant plastic deformation before rupture.

Multiple Choice

What is malleability?

• Malleability is the ability to conduct electricity.
• Malleability is the ability of a material to be shaped or deformed without breaking.
• Malleability is the process of breaking materials into smaller pieces.
• Malleability refers to a material's resistance to heat.

What do you think is extensive properties?

Word Cloud

Give an example of extensive properties

Would a larger sample bubble more in vinegar?

Would the mass or volume of each sample change the results

Can physical properties alone always help identify a substance? Why or why not?
