Product Description
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/Summary Project to inspire higher-order learning

A description of the activities at each station in this particular lab is detailed below.

Next Generation Science Standards
This laboratory partially satisfies NGSS MS-PS4-1. It combines the three dimensions of science learning - science and engineering practices, disciplinary core ideas and crosscutting concepts - in order to meet the standard. This laboratory also makes interdisciplinary connections to STEM, Math CCSS and ELA CCSS to build the appropriate skills.

Mathematical Models of Waves Lab Stations Activity Learning Objectives
1. Interpret, analyze and draw graphs to quantitatively describe the properties of a mechanical wave.
2. Use mathematical equations make calculations to describe a mechanical wave’s frequency, wavelength and velocity.
3. Manipulate physical models to explain how wave characteristics correspond with physical observations.

Science Skills Station
Students will use graphs to quantitatively and qualitatively describe characteristics of transverse waves. They will create, analyze and interpret graphs of waves with different characteristics. Students will also make calculations to quantitatively describe a mechanical wave’s frequency, wavelength and velocity.

Narrative Station
Students will read short informational texts at this station about wave properties and using mathematical models to study waves. Specifically, students will read about using graphs and equations to describe wave properties.

Assessment Station
At this station, students will answer questions about key terms and ideas relating to the use of wave models to describe wave properties. Students will have to employ lower, mid and higher order thinking skills to answer these questions.

Problem-Solving Station
Students will use a wave machine to study wave characteristics. Students will use it to make physical observations of wave characteristics. Students will manipulate the wave machine so to better understand how changing one feature alters other wave characteristics.

Synthesis/Summary 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.

• A pre-lab assignment and post-lab reflection
• Directions and questions for each lab station
• Student recording sheets
• Teacher Key

2 Calculators
Duct tape or packing tape
50 12-inch wooden skewers
Dots candy (4 boxes/200 candies)
Two chairs
Stopwatch (optional)
Ruler (optional)

Important Note:
This laboratory requires 15-30 minutes of teacher preparation.
