Assessment Criteria for MS-PS1

What is the goal of MS-PS1-1 in the topic assessment criteria?

• Develop models to describe the atomic composition of simple molecules

• Analyze and interpret data on the properties of substances

• Determine if a chemical reaction has occurred

• Conduct a full lab report

Answer explanation

The goal of MS-PS1-1 is to develop models that illustrate the atomic composition of simple molecules, which helps students understand the structure and behavior of matter.

What does MS-PS1-2 focus on in the topic assessment criteria?

• Developing models of atomic composition

• Analyzing and interpreting data on the properties of substances

• Writing a full lab report

• Describing the atomic composition of molecules

Answer explanation

MS-PS1-2 emphasizes analyzing and interpreting data related to the properties of substances, which is crucial for understanding chemical behavior and interactions.

What is included in the topic assessment criteria along with MS-PS1-1 and MS-PS1-2?

• A summary report

• A full lab report

• A presentation

• A quiz

Answer explanation

The topic assessment criteria for MS-PS1-1 and MS-PS1-2 includes a full lab report, which allows students to demonstrate their understanding of scientific concepts through detailed experimentation and analysis.

What does the term 'matter' refer to?

• Anything that has mass and takes up space

• Only things that can be seen

• Only liquids and solids

• Only things that are alive

Answer explanation

The term 'matter' refers to anything that has mass and occupies space, including solids, liquids, and gases. This definition excludes options that limit matter to visible objects, only liquids and solids, or living things.

How can you demonstrate that matter exists in a balloon?

• By inflating and deflating it

• By painting it

• By cutting it

• By freezing it

Answer explanation

Inflating and deflating a balloon demonstrates that matter exists because it shows the presence of air inside. The change in size indicates that air, a form of matter, occupies space within the balloon.

What is the smallest possible unit that takes up space?

• Molecule

• Cell

• Atom

• Particle

Answer explanation

The smallest possible unit that takes up space is an atom. Atoms are the basic building blocks of matter, consisting of protons, neutrons, and electrons, and they combine to form molecules and cells.

What is the process of collecting data from natural phenomena using our senses and scientific tools called?

• Scientific Observations

• Scientific Theories

• Scientific Laws

• Scientific Hypotheses

Answer explanation

The process of collecting data from natural phenomena using our senses and scientific tools is called Scientific Observations. This involves directly observing and recording information, which is fundamental to scientific inquiry.

Which of the following is NOT one of the senses used in scientific observations?

• Touch

• Smell

• Telepathy

• Hearing

Answer explanation

Telepathy is not one of the senses used in scientific observations. The senses used include touch, smell, and hearing, which are all physical senses that allow us to gather empirical data.

What is the correct sequence of steps in scientific observations as mentioned in the document?

• Questions → Observations → Experimenting → Solutions → Conclusions

• Observations → Questions → Experimenting → Conclusions → Solutions

• Experimenting → Observations → Questions → Solutions → Conclusions

• Solutions → Observations → Experimenting → Questions → Conclusions

Answer explanation

The correct sequence starts with Observations, leading to Questions, followed by Experimenting, then Conclusions, and finally Solutions. This reflects the logical flow of the scientific method.

What is the first step in the "See, think, wonder" activity?

• 10 observations

• 2 wonderings

• 2 testable questions

• 5 explanations

Answer explanation

The first step in the "See, think, wonder" activity is to make 10 observations. This foundational step helps participants gather information before moving on to wonderings and questions.
