Musical Bow
WHAT WILL YOU MAKE?
A musical bow you can use to play string instruments!
WHAT WILL YOU LEARN?
You will learn to use a coping saw on a woodworking project. You will also learn to string a simple instrument.
STEPS
STEP 1
Cut some notches
Cut two notches in each end of the wooden strip with the coping saw. Make the marks roughly 1/2 inch deep, and space them out evenly
STEP 2
Add the strings
Tie a loop in one end of the fishing line and hook it onto the notches in one end of the wood strip. » Run the fishing line to the other end of the strip, then slide it into one notch and back through the other notch. » Repeat theis process 4-5 times.
STEP 3
Bend the bow
Bend the strip of wood slighly, and tighten the strings by tugging the excess slack through the notches. This may require a second person. » Tie off the fishing line by wrapping it around the notches several times, then cut the line from the spool. » Near each end of the bow, twist a twisty tie around the strings to bunch the strings together.
WHAT'S HAPPENING HERE?
The purpose of applying rosin is to coat the bow hairs in a powdery, sticky substance that will “grip” the strings and cause friction as the bow slides across the string. This is what causes the string to vibrate and produce sound.
Materials:
- Long Bendy Strip of Wood (roughly 3'x1"x1/4")
- 20-pound Fishing Line
- 2 Twisty Ties
- Small Block of Wood (roughly 2"x1"x1")
- Coping Saw
- Scissor
- Glue Stick or Rosin if you have it

Maker Camp Project Standards
Based on NGSS (Next Generation Science Standards)
National Core Arts Standards
The National Core Arts Standards are a process that guides educators in providing a unified quality arts education for students in Pre-K through high school. Also see Standards with cross-cutting anchors in Creating, Performing, Responding, and Connecting through art for Music.NGSS K-2 Engineering Design
The Next Generation Science Standards (NGSS) are K–12 science content standards.- K-2-ETS1-1. Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.
- K-2-ETS1-2. Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
- K-2-ETS1-3. Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
NGSS 3-5.Engineering Design
The Next Generation Science Standards (NGSS) are K–12 science content standards.- 3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
- 3-5-ETS1-2. Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
- 3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
NGSS MS.Engineering Design
The Next Generation Science Standards (NGSS) are K–12 science content standards.- MS-ETS1-1. Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
- MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
- MS-ETS1-3. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
- MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
NGSS HS.Engineering Design
The Next Generation Science Standards (NGSS) are K–12 science content standards.- HS-ETS1-1. Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
- HS-ETS1-2. Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
- HS-ETS1-3. Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics as well as possible social, cultural, and environmental impacts.
- HS-ETS1-4. Use a computer simulation to model the impact of proposed solutions to a complex real-world problem with numerous criteria and constraints on interactions within and between systems relevant to the problem.
