A mouthpiece is designed in such a way that it concentrates, or forces sound across a column of air. How did you do this with the straw instruments you designed last week?
your mouth has a big sound and it is forced through a smaller hole in the straw and then is released through the opening,it changes when You cut a shape into the top or press lips to it
Sci.SI1.1: Using experimentation, students will contrast types of forces
Benchmark assessment: Students will create a Video voiceover a clip on YouTube, taking the role of a science broadcast announcer.
Components
Students will:
Sci.SI1.1.1 Demonstrate how balanced and unbalanced forces are related to motion.

Sci.SI1.2: Through research and inquiry, students will apply the concepts of transverse waves to the use of sound and light wave technology.
Benchmark assessment: Student will synthesize their knowledge of light and sound waves to make a musical instrument that can play at least four distinct pitches and use the music created as part of a shadow puppet show.
Components
Students will:
Sci.SI1.2.1 Experiment with sound and light waves to identify the following structures or relationships: crests, troughs, frequency, wavelengths, amplitude, energy transmission, resonance(standing waves) and speed
Sci.SI1.2.2 Identify and experiment with part of the electromagnetic spectrum.
Sci.SI1.2.3 Use light to create penumbras, umbras, and colored shadows.
Sci.SI1.2.4 Experiment with wind or string instruments of varying pitch.
Sci.SI1.3: Through experimentation, Students will observe energy transformations, including potential and kinetic energy
Benchmark assessment: Students will create mousetrap cars and reflect upon the energy transformations.
Components
Students will:
Sci.SI1.3.1 Model changes in gravitational potential energy, spring potential energy, and kinetic energy.
Sci.SI1.3.2 Examine the energy changes in a variety of simple machines
Sci.SI1.3.3 Analyze the effectiveness of a machine for a job using its actual mechanical advantage.
Sci.SI1.4: Using inquiry and models, students will utilize alternative energies.
Benchmark assessment: Students will build a structure that allows us to utilize solar or wind energy in a useful way.
Students will:
Sci.SI1.4.1: Experiment with passive and active solar energy.
Sci.SI1.4.2: Experiment with models of wind energy.
Sci.SI1.4.3? Explain energy transformations in alternative energies.
Sci.SI1.5: Students will model heat transfer mechanisms as a rationale for weather and plate movement on the earth.
Benchmark assessment: Students will create a coloring book that shows the concepts of the chapter in a way that is understandable to a young reader.
Students will:
Sci.SI1.5.1: Contrast convection, conduction, and radiation inside the earth, in its water and weather patterns, and from the sun.
Sci.SI1.5.2: Examine the prevailing winds at different locations on earth, and discuss the movement of weather systems.
Sci.SI1.5.3 Model plate tectonics, earthquakes, and volcanos.
Sci.SI1.5.4: Analyze fossils and other technologies for tracking plate movement
Sci.SI1.6: Students will apply knowledge of geochemical cycles to the issue of climate change.
Benchmark Assessment: Students will come up with a life plan that discusses their usage of various cycles and ways to minimize their effect on the planet.
Students will:
Sci.SI1.6.1: Diagram movement of material between geochemical reservoirs.
Sci.SI1.6.2: Contrast the effect of various geochemical cycles on temperature and atmospheric concentration.
Sci.SI1.6.3: Quantify amounts of material found in reservoirs through visual and experimental models.
Sci.SI1.6.4: Explore ways to minimize their carbon footprint.
Sci.SI1.7: Students will apply their knowledge of the origin and scale of
space.
Benchmark Assessment: Students will create museum exhibits that are interactive, visual and three-dimensional to illustrate their understanding of the components.
Students will:
Sci.SI1.7.1: Model the solar system size and scale.
Sci.SI1.7.2: Examine distances in the cosmos based upon the concept of light speed.
Sci.SI1.7.3: Create time scales for geology on earth, the formation of the solar system, and the big bang.
Sci.SI1.7.4: Examine the process of radioactivity in a star like our Sun, and model its life cycle.

we cut it in to the shape of a triangle so it was like a wind instrument
your mouth has a large sound in it, and it is forced through the small hole in the straw, and then is released through the opening, still small
we blow air into it and pinched the end that we blow into
We made it so we could make sounds by blowing into it..
The top was cut into a triangle so it acts like a wind istrument
we cut so it makes more vibrations which made the noise louder.
we cut it so it looked like a triangle....so then when you blow into it..it has to go through a smaller hole and yea it makes a louder sound......
it vibrated in the air in the middle of the straw up and down down on all sides it bounced on the walls of the straw and made it louder
You cut a triangle in the top of the straw with sicissors and then you blow into it pinching the top of it.
we pinched the end of the straw and watch it viberate
we cut it out so it had a triangle shape and blew into it.
we cut it into a shape of a triangles so it was like a windintrument
We cot in like a triangle and when we blew on it it vibrated so it made sound
it was a wind instrument
we cut a triangle at the top to blow on
cut it into a triangle.
