P.S. 211 Winter 2023 STEM Newsletter (4th Grade)
Vision and Light
Fourth Grade Conservation Biologists have been exploring their second science unit by gathering evidence from texts, investigating and collecting data using digital simulations, developing models and discussing their ideas with classmates.
In this unit, students investigate the role that animal senses, primarily vision, play in survival. They investigate why there is a decline in the number of Tokay geckos living in one area of a rainforest in the Philippines. They will do this by studying the following big ideas:
- Animals have different structures that allow them to get information from their environment, which helps them survive. Light, sound and scent can carry information about the environment to an animal.
- Light needs to get to an object for an animal to see the object.
- When scientists change only one variable in an investigation, they can figure out if it makes a difference.
We encourage you to ask your 4th Grade Conservation Biologist about what they are learning in class!
- How do animals use their senses to get information about their environment?
- How does light allow an animal to see something?
- How do an animal's structures allow it to see its prey?
