RPAT 2 Preventing Light and Sound from Escaping a Model Factory
Students will work in groups to identify what objects that emit their own light and create something that can reduce sound and light pollution escaping from these objects in factories.The teacher will provide each group with a model factory(a cardboard box with holes for windows cut out of it). The students will use a variety of various materials and techniques to stop the sound and light from escaping the box. The structure of the box cannot be changed just as a factory structure cannot be changed. The students will put an ipad in the box (with the screen on) to minic lights in a factory and will play music from the ipad (to mimic the sound coming from a factory). The students will decide if they will absorb, reflect, or refract the light and sound from a factory, and which materials they will use to stop the light and sound.
Assessment of Learning: The students will create a poster with information about their materials, techniques, and a rationale for how they stopped the light and the sound. Each student will create a 1 minute oral presentation about their poster and their project. Each student will deliver their oral presentation to the class.
Apart from the assessment, the students will also be prepared to use the presentation that they gave to the class to talk to parents who visit their display at a school-wide parent/community innovation evening.
2.6 use appropriate science and technology vocabulary, including natural, artificial, beam of light, pitch, loudness, and vibration, in oral and written communication
3.3 describe properties of light, including the following: light travels in a straight path; light can be absorbed, reflected, and refracted
3.4 describe properties of sound, including the following: sound travels; sound can be absorbed or reflected and can be modified
-
3.6 describe how different objects and materials interact with light and sound energy (e.g., prisms separate light into colours; voices echo off mountains; some light penetrates through wax paper; sound travels further in water than air)
-
-
-
2.4 use technological problem-solving skills (see page 16) to design, build, and test a device that makes use of the properties of light (e.g., a periscope, a kaleidoscope) or sound (e.g., a musical instrument, a sound amplification device)
-
-
- use speaking skills and strategies appropriately to communicate with different audiences
for a variety of purposes;
-
- Investigate the characteristics and properties of light and sound
- demonstrate an understanding of light and sound as forms of energy that have specific characteristics and properties.
2.3 communicate in a clear, coherent manner,
presenting ideas, opinions, and
information in a readily understandable
form
2.4 use appropriate words and phrases
from the full range of their vocabulary,
including inclusive and non-discriminatory
terms, and appropriate elements of
style, to communicate their meaning
accurately and engage the interest of
their audience
-
2.5 identify some vocal effects, including
tone, pace, pitch, volume, and a range
of sound effects, and use them appropriately
and with sensitivity towards
cultural differences to help communicate
their meaning
2.6 identify some non-verbal cues, including
facial expression, gestures, and eye contact,
and use them in oral communications,
appropriately and with sensitivity
towards cultural differences, to help
convey their meaning
2.7 use a variety of appropriate visual aids
(e.g., CDs or DVDs, computer-generated
graphic organizers, concrete materials,
artefacts) to support or enhance oral
presentations
