Every musical instrument is different, but they all have one thing common: they convert energy from motion into sound by causing a part of the instrument to vibrate. These vibrations cause waves in the air that, when sensed by our ears, are interpreted as sound. Sound waves travel at different speeds depending on the source of the vibrations. The faster a sound wave moves, the higher the pitch of the sound.

This sequence of instruction was developed in the Growing Elementary Science Project to help elementary teachers who were working remotely.  We developed a short storyline that ties together a few sessions to help explore a specific concept.  We tried to include some activities that honored and included the student’s family and experience, and some that included the potential for ELA learning goals.Unlike other units in our series, this was not developed as a complete stand-alone unit. Our intent, in this case, was to provide a set of options for the teacher, as well as some materials for consideration of opportunities to integrate reading in science.It is part of ClimeTime - a collaboration among all nine Educational Service Districts (ESDs) in Washington and many Community Partners to provide programs for science teacher training around Next Generation Science Standards (NGSS) and climate science, thanks to grant money made available to the Office of the Superintendent of Public Instruction (OSPI) by Governor Inslee. 

Solar energy in the form of light is available to organisms on Earth in abundance. Natural systems and other organisms have structures that function in ways to manage the interaction with and use of this energy. Using these natural examples, humans have (in the past) and continue to design and construct homes which manage solar energy in passive and active ways to reduce the need for energy from other sources. In this storyline, students will explore passive and active solar energy management through examples in the natural world. Students will use knowledge gained to design a building that maximizes the free and abundant energy gifts of the sun.

PhD Science Grade Levels K–2 is available as downloadable PDFs. The OER consists of Teacher Editions and student Science Logbooks for every module.

With PhD Science®, students explore science concepts through authentic phenomena and events—not fabricated versions—so students build concrete knowledge and solve real-world problems. Students drive the learning by asking questions, gathering evidence, developing models, and constructing explanations to demonstrate the new knowledge they’ve acquired. The coherent design of the curriculum across lessons, modules, and grade levels helps students use the concepts they’ve learned to build a deep understanding of science and set a firm foundation they’ll build on for years to come.

Cross-curricular connections are a core component within PhD Science. As an example, every module incorporates authentic texts and fine art to build knowledge and create additional accessible entry points to the topic of study.

Three-dimensional teaching and learning are at the heart of the curriculum. As students uncover Disciplinary Core Ideas by engaging in Science and Engineering Practices and applying the lens of Cross-Cutting Concepts, they move from reading about science to doing science.

Vibrating materials can make sound, and sound can make materials vibrate. When a mallet taps the glass, the water inside the glass vibrates. The pitch of the sound depends on the speed of the vibrations. Since the glass with the most water slows down the vibrations the most, it produces a lower pitched sound.

You hear sounds when vibrations go inside your ears and stimulate your nerves to send electrical signals to your brain. For instance, when the spoon is bumped against an object, it vibrates. As it vibrates, it sends out sound waves that bump into air molecules and cause them to bounce to and fro. Those bouncing air molecules bump into other air molecules and start them moving. This chain reaction of moving air molecules carries sound through the air in a series of waves that we call sound. Inside your ear, moving air molecules push on your eardrum and cause it to vibrate.
