This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

Elementary Middle School High School

1-PS4-3

Students can use these lenses to conduct an investigation of how different materials affect the path of light.

2-PS1-2

Students can use these in an investigation where these lenses and other different materials are tested with analyze data and determine which materials have the properties that are best suited for an intended purpose.

5-PS1-3

Students can use these lenses to make observations and measurements to identify materials based on their properties.

MS-PS4-2

Students can use these lenses to develop and use a model to describe how waves are reflected, absorbed, or transmitted through various materials.

HS-PS4-1

Students can use these lenses to conduct investigations and use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.

HS-PS4-5

Students can use this lens to conduct investigations about technological devices use the principles of wave behavior and wave interactions with matter to transmit.

Suggested Science Idea(s)

2-PS1-2

Students can experiment with a variety of materials to determine which ones are best suited for an intended purpose such as seeing around a corner.

5-PS1-3

Students can use these lenses to test for reflectivity when shinning it with a light or laser.

MS-PS4-2

Students can use these lenses and other objects during investigations about what materials allow the light from a laser to pass through, be absorbed or reflected.
