MS-PS4-3 Analog vs. Digital Signals Lab Activity | Printable, Digital & Editable

About SNAPs Lab Stations Activities

SNAPs Lab Stations Activities require students to use science, math, literacy, problem-solving and engineering skills. They are designed to enhance students' understanding of scientific concepts and help students apply scientific ideas to the real world. Each station activity promotes skills so to develop students into proficient and competent scientific thinkers.

SNAPs lab activities have five components:

• Science Skills Station to develop science skill proficiency

• Narrative Station to build science literacy

• Assessment Station to evaluate learning and understanding

• Problem-Solving Station to foster engineering design

• Synthesis Station and Project to inspire higher-order learning

The activities at each station in this lab are detailed below.

Analog vs. Digital Signals Lab Learning Objectives

1. Explain how wave signals can be used to communicate or transmit information.

2. Compare and contrast an analog signal and a digital signal.

3. Assess the digitalization of instrumentations in the ability to conduct scientific investigations.

4. Evaluate the claim that digital signals are a more reliable way to encode and transmit information than analog signals.

Science Skills Station

Students will complete a classification activity at this station. Students will classify signals as analog or digital. Then students will complete an activity to assess how the digitalization of technologies has impacted the ability to conduct scientific investigations.

Narrative Station

Students will read a passage about analog and digital wave signals. Then students will watch a video about how information can be coded into analog or digital signals so to communicate or store information.

Assessment Station

At this station, students will answer questions about key terms and ideas relating to digital and analog wave signals. Students must employ lower, mid and higher order thinking skills to answer these questions.

Problem-Solving Station

Students will evaluate the reliability of using digital and analog signals to carry information. Specifically, students will evaluate how well a digital and analog signal record or encode, store and transmit information.

Synthesis Station

Students will compose a CER (claim-evidence-reasoning) report to summarize the lab. Students are provided the claim statement and must support the claim with observations, data and other information gathered in the lab. Students will explain how the evidence supports the claim using scientific reasoning.

Synthesis Project

Students will have a choice of 11 projects. Refer to the SNAPs Lab Stations Best Practices and Setup Guide for directions and suggestions on how to conduct the project.

This download includes:

• A pre-lab assignment and post-lab reflection

• Directions and questions for each lab station

• Student recording sheets

• Teacher Key

Additional Materials Required:

3 Ziploc bags

2 Computers or tablets

LINKS TO VIDEOS

This laboratory requires internet to access videos. Videos are hosted on SafeShare.TV so to safely watch and share educational YouTube videos without ads, comments and other distractions. Shortened and full link(s) to SafeShare.TV included. Full link to original YouTube video(s) included.

NEXT GENERATION SCIENCE STANDARDS

This laboratory satisfies NGSS 4-PS4-3. It combines the three dimensions of science learning - science and engineering practices, disciplinary core ideas and crosscutting concepts - to meet the standard. This lab also makes interdisciplinary connections to STEM, Math CCSS and ELA CCSS to build the appropriate skills.
