This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.

In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this activity, learners create a hearing based memory game that they can share with friends.

This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

In this activity, learners create a straw oboe to explore sound and pitch.

In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.

This activity includes several games about animal sounds. Using their sense of hearing and communicating with various kinds of noisemakers, learners role-play predator and prey.

In this activity, learners will create their own percussion instrument with recycled materials. Learners will explore design, fabrication, cause and effect and sound through this activity.

In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

In this activity, learners build unique sound enhancing inventions with items from around the house to amplify sound from their smart phone's speakers.

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

With three cans and some tape, make a drum that you bonk down on any surface to produce a variety of sounds. This activity also teaches you about pitch, vibration, and frequency.

In this activity, learners explore sound by constructing their very own bagpipe instrument.

In this activity, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to explore the interplay of motion and sound.

In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.

In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
