Description

This hands-on DIY kit is an ideal STEM and makerspace material for primary to secondary school students and hobbyists. LEGO-like flexible building blocks help students (ages 9+) understand modern electronics. Comes with step-by-step instructions and a variety of components that can be repeatedly used for multiple projects. No soldering is involved. Students will learn how to use an integrated circuit (IC) to amplify sound signals. The stereo uses a TDA2822 m IC chip to amplify sound signals input from an audio device such as a smart phone, iPod, or MP4 player. The stereo signals produced by the chip are delivered to two speakers. Although simple, the amplifier can still produce high quality and volume sound. The circuit can be easily expanded to include a Bluetooth module for wireless sound input.

Materials Included in the Kit:
(1) 5eBoard standard kit; (2) Two speakers and all electronics components (iPod is not included); (3) An audio cable and connection wires; (4) Instruction manual (online download).

Required tools and supplies (not included):
A wire stripper/cutter; AAA (or AA) batteries

NGSS

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

Elementary Middle School High School

3-5-ETS1-2

Students can use this 5eBoard kit to 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.

MS-ETS1-2

Students can use this 5eBoard kit to evaluate competing design solutions using a systematic process to determine how well they meet criteria and constraints of the problem.

HS-PS3-2

Students can use this 5eBoard kit to develop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields.

HS-PS3-5

Students can use this 5eBoard kit to develop and use a model of two objects interacting through electric fields to illustrate the forces between objects and changes in energy of the objects due to the interaction.

HS-ETS1-2

Students can use this 5eBoard kit to design a solution by breaking it down into smaller, more manageable problems that can be solved through engineering.
