NGSS Disciplinary Core Ideas

• PS1.A: Structure and Properties of Matter:
  • Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. (MS-PS1-2), (MS-PS1-3)
• ESS3.A: Natural Resources:
  • Humans depend on Earth’s land, ocean, atmosphere, and biosphere for many different resources. Minerals, fresh water, and biosphere resources are limited, and many are not renewable or replaceable over human lifetimes. These resources are distributed unevenly around the planet as a result of past geologic processes. (MS-ESS3-1)
• ESS3.C: Human Impacts on Earth Systems:
  • Human activities have significantly altered the biosphere, sometimes damaging or destroying natural habitats and causing the extinction of other species. But changes to Earth’s environments can have different impacts (negative and positive) for different living things. (MS-ESS3-3)

Students learn:

• Chemists observe substances in order to identify their properties.
• Scientists work in communities to help keep water clean and safe for consumption.
• Science investigations use a variety of methods and tools to make measurements and observations.

Lesson at a Glance

1: Warm-Up (5 min.)

This activity provides a connection between students' everyday lives and the question they will be investigating in the unit.

(Teacher Only) Video: Using Chemistry to Keep Water Safe (5 min.)

A video establishes an authentic backdrop for the unit investigation by introducing students to a scientist who uses chemistry to make water safe to use.

2: Investigating a Mysterious Substance (15 min.)

Students are introduced to the problem they will be solving and are given an opportunity to share their initial ideas about it.

3: Observing Substances (20 min.)

Students make observations of the three substances mentioned in the claims they are considering. They are introduced to the concept of properties.

NGSS Disciplinary Core Ideas

• PS1.A: Structure and Properties of Matter:
  • Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. (MS-PS1-2), (MS-PS1-3)

Students learn:

• Different substances have different properties.
• More detailed observations provide stronger evidence.
• Scientists can use properties to help them distinguish between different substances.

Lesson at a Glance

1: Warm-Up (5 min.)

Students are primed for the idea that more detailed observations make better evidence.

2: Making Detailed Observations (5 min.)

Students are formally introduced to a criterion for evaluating the quality of evidence. This Evidence Criterion will serve as an important focus of this unit.

3: Investigating Substances (20 min.)

Students practice making detailed observations as they gather evidence to help them answer the Investigation Question.

4: Evaluating Evidence (15 min.)

Students use a digital version of the Evidence Gradient to identify pieces of strong evidence. This will allow students to answer the Investigation Question. The teacher uses this opportunity as an On-the-Fly Assessment of students' ability to analyze data.

5: Homework

Students are given the chance to apply what they have learned about properties by comparing two different substances that they have in their home.
