Physical & Chemical Changes Digital Inquiry Lab - NGSS MS PS1-2

Want an INTERACTIVE and FLEXIBLE LAB DAY? Engage your students with a virtual demonstration and pre-recorded video or let them conduct the hands-on printed experiment. Both versions include comprehension questions, Claim-Evidence-Reasoning (C.E.R.) prompts, and a reflection section.

Differentiation is built in with three full versions at different levels of difficulty.

In this lab, students will distinguish between physical change and chemical change by completing the process of saponification (making soap). Additionally, students will observe an exothermic reaction.

Essential Questions:

• What is the difference between a physical and chemical change? How can these be observed during the process of saponification?

Standard:

• NGSS MS PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

What's Included?

Print Format:

This in-person laboratory experiment with hands-on procedures is meant to be printed out for student use. Each student should fill out their own sheet, even if they work in groups.

Materials Needed Per Group:

• goggles
• apron
• gloves
• beaker tongs
• hot plate
• thermometer
• stirring rod
• foam cup
• 250 mL beaker
• 250 mL Erlenmeyer flask
• 50 mL graduated cylinder
• 100 mL vegetable, coconut, or olive oil
• 46 mL cold distilled water
• 14 g NaOH (lye) *CAUTION: CAUSTIC*
• ½ of a crayon
• pH strips
• fragrance oil (optional)

Digital Format:

This completely virtual, interactive PowerPoint file is compatible with Google Slides and can be attached to assignments in MS Teams, Schoology, Canvas, etc.

*NEW* This digital lab contains a video recording of the entire lab procedure. Students will follow along with a teacher as they create soap in the lab using a crayon, oil, lye, and cold distilled water.

Materials Needed:

None! Don’t have materials? Students absent? Interactive virtual activities right inside the file give the students a way to experience the science.

Three Differentiated Versions

Within each format (print and digital), the lab is further separated into three levels:

• Dependent – Suggested for on-level learners.
  This level is written with a combination of procedural instructions and inquiry questions. They are moderately student-centered with guided inquiry questions throughout the lab.
• Modified – Suggested for learners utilizing modifications.
  This level provides the most structured lab experience. The lessons may eliminate parts of the lab and change the questioning to include sentence stems or multiple-choice options.
• Independent – Suggested for advanced learners.
  This level is the most student-led experience. Suggestions are made for the students to get started, but most of the decisions will be student-centered. The students will be responsible for most aspects of the lab and will have the least guidance.
