With all of the noise makers and banging pots and pans to ring in the new year, add this sound experiment into the mix! Using materials you can find right at home, you can experience the science of sound waves!
You will need:
One metal teaspoon
One metal serving spoon
4 feet of yarn
Wooden or heavy plastic ruler
Lets try it!
Make a loop in the center of the length of yarn. Insert the end of one spoon and pull the yarn tight. There should be a loose knot around the handle of the spoon.
Wrap the ends of the string around your pointer fingers. Hold the string up to your ears.
Have your friend hit the round part of the spoon using the ruler. Listen to the noise traveling through the string to your ears! Is it loud? Soft? Does it sound like a bell? Or a gong? Is the pitch high or low?
Repeat all three steps with both sizes of spoons and compare the sound that they each produce!
Every time you hear a sound, there are sound waves traveling through the air, or through a string, until it reaches your ears. This experiment demonstrates the way that sound can travel through a material straight to your ear.

There are so many fun science experiments you can do at home! Check these 8 safety rules so that you can stay safe and have fun while you learn something new.
1. Adult Supervision
When doing any experiment at home, it is important to have adult supervision. Many experiments involve household chemicals or the stove top. Always ask an adult to help you find and use chemicals for an experiment, and never use the stove top without an adult present.
2. Appropriate Clothing
Just like in a real laboratory, it is important to wear safe clothes while experimenting at home. Loose clothing that could catch on fire or get in the way of an experiment can be a hazard. Wear an outfit that fits you well. Wearing closed toed shoes and tying back long hair will also help to keep you safe as you experiment.
3. Protective Gear
For some experiments, you must wear protective gear. Whenever you experiment with chemicals or mixing, it is important to protect your eyes and skin. Safety goggles, gloves, and a lab coat or apron can be worn to keep you safe.
4. Follow the Instructions
Doing a science experiment can be fun and creative, but it is important to find and follow a set of general instructions to help you stay safe. Read the important information about the materials and procedure carefully before you begin your experiment. Following the instructions will help to keep you safe and out of trouble while experimenting.
5. Pay Attention
Experiments requires a lot of focus. When you are doing an experiment at home, you must pay attention to what you are doing and what is happening around you. This is important to avoid an accident. Always be aware of the objects sitting on your work space, and of the people you are working with.
6. Measure Carefully
When experimenting with varying amounts of materials, measuring carefully can help you stay safe and get better results. Use a standardized measuring container and check twice to ensure you are using the correct amount.
7. Avoid Horseplay
It is fun to run around and be wild, but not during an experiment. Stay safe by being careful to walk, not run, and to keep your hands to yourself. Avoid horseplay and running so that you can also avoid spills and injuries.
8. Clean Surfaces
Start with a clean surface before you do an experiment. Keep your workspace clean and not over crowded. Making a mess during an experiment could result in an injury. Clean up spills as soon as they happen, and remember to clean up and put everything back in it’s place when you are done with the experiment.
Remember these 8 Safety Rules every time you do an experiment. Let us know what experiments you like to do at home! Learn more about experimenting with us at The STEM Shoppe by visiting our website at www.TheStemShoppe.com.
At the STEM shoppe, we love neat STEM tools that help us learn about technology, engineering, science and mathematics! Using a variety of resources to engage in learning helps to make STEM so much fun! What is your favorite STEM tool?
Dash and Dot
If you have been to the STEM shoppe, you have met our blue friends, Dash and Dot! These adorable robots are an incredible STEM tool! Dash and Dot are interactive, friendly robots with fun and challenging software. Learning with Dash and Dot is never dull as you experiment with the fascinating features and exciting adventures. These amazing STEM robots help you improve hand eye coordination, and learn how to program.
Another amazing STEM tool we love at the STEM shoppe is the Arduino microcontroller. This tiny, powerful microcontroller combines computer programing skills with electric circuits; bringing a computer code to life. With the Arduino microcontroller, you can learn how to code a lightbulb to blink or a robot’s wheels to whir. The possibilities are endless with this neat technology.
Van de Graaff Generator
Have you ever heard of a Van de Graaff Generator? This amazing STEM tool harnesses the power of static electricity! This hands-on learning devices helps you learn incredible principles about energy fields, lightning, and static attractive and repulsive forces. And you may end up with a wild hairdo!
3D printing is revolutionizing the way products are being designed and manufactured. This new technology is one of our favorite STEM tool at The STEM Shoppe. Engineering a design for a 3D printer incorporates computer software, problem solving redesigns, and many aspects of the engineering process. Learn about toy design, manufacturing, and bring your ideas to life with a 3D printer.
What makes an iPad an amazing STEM tool? The hand held, touch screen technology of a tablet opens worlds of possibilities for young learners. We love using iPads at The STEM Shoppe as a resource for research, learning software, and hands on application of technology. Tablets of any type are a valuable learning tool that can even be used at home! Educational apps make learning engaging, versatile, and so much fun!
