Students will create a musical pipe using straws of different lengths. They will create their own tune.
This parent guide supports parents in helping their child at home with the 2nd Grade Science content.
This resource accompanies our Rethink 2nd Grade Science Forces & Motion unit. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning.
This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 2nd Grade Science in Forces & Motion.
Thomas Edison is a famous inventor. His work with the telegraph and telephone led him to invent the phonograph, which recorded sound as indentations on a sheet of paraffin-coated paper. Students can listen to his first recordings at the NPS (National Park Services) archives. Students will learn how to create their own recordings at the Online Voice Recorder.
Students will work individually to design and build an instrument out of provided materials to make the loudest instrument they can. Students will need to work out what materials will cause vibrations in order to make sound. Students will be allowed to touch and plan before design as well as have time to fix and rebuild. The students will need at least an introduction to instruments and how their sound is created.
This unit aligns to the North Carolina second grade science standards 2.P.1 Understand the relationship between sound & vibrating objects.
In this lesson, students use their knowledge of sound energy to create a soundproof box to protect a secret code word! Students measure and graph decibels to determine how well their boxes omit sounds!
Students will learn how sound travels through different materials. They will be involved in activities to explore how they can create sounds using different materials. They will be involved in activities to experience pitch and volume and how you can create different pitch and volume using different materials. They will design an instrument using recycled materials.
Waves and their Applications in Technologies for Information Transfer, from NGSS 1PS 4-1, 4-2, 4-3, and 4-4.
Driving Question: How can I, as a 1st grade engineer, design a device to let people know I am safe, using light and sound?
Pack your suitcase and join us for a trip around the world to explore some unique habitats and how animals survive in them!
