DAY AND NIGHT ELECTRIC LIGHT
Students view a video and create a Venn Diagram of things that are seen in the daytime, in the nighttime, and in both. They trace shadows a few times throughout the day to see how they change. They learn about the causes of day and night and how humans manipulate the environment at night for our own needs through the use of electricity. The teacher reads the book "Rosa and Effy’s Adventure", noting the night sky, shadows, and the use and abuse of electricity. Students then design and build a device to keep an ice cube from melting comparing their results to a control to determine effectiveness.
1-ESS1-1 - Use observations of the sun, moon, and stars to describe patterns that can be predicted.
K-2 ETS1-1- Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.
K-2 ETS1-3- Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
SOUND AND LIGHT ARE ENERGY
Students begin by viewing a video of dancing oobleck sharing observations. They perform stations on sound sharing their observations and then developing explanations. Students examine shadow art as an introduction to light and perform a light exploration lab. They gather explanations through books and video. Finally, students discuss and then design a way to communicate across a distance with light and/or sound.
1-PS4-1 - Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate.
1-PS4-2 - Make observations to construct an evidence-based account that objects in darkness can be seen only when illuminated.
1-PS4-3 - Plan and conduct investigations to determine the effect of placing objects made with different materials in the path of a beam of light.
1-PS4-4 - Use tools and materials to design and build a device that uses light or sound to solve the problem of communicating over a distance.
