K-ESS3-3

SCUSD NGSS Curriculum Guide

====**K-ESS3-3: Communicate solutions that will reduce the impact of humans on the land, water, air, and/or other living things in the local environment.* ** [Clarification Statement: Examples of human impact on the land could include cutting trees to produce paper and using resources to produce bottles. Examples of solutions could include reusing paper and recycling cans and bottles.] ====

Science Background for the Teacher:
Resources are limited and while many materials are recyclable it is important to remember that everything humans do impacts the Earth and environment. Examples could include:
 * Overfishing
 * Deforestation
 * Pollution

Key Vocabulary:

 * Reduce || Reuse || Recycle ||
 * Land || Water || Air ||

Possible Assessments (formative and/or summative):
Sorting bag of different materials that are reuse vs recycle

Key Student Activities:
Making paper- Paper Recycling in Kinder FOSS kit- Wood & Paper Making plywood- Making Sandwich Wood in Kinder FOSS kit- Wood & Paper Sorting lunch or classroom trash into appropriate categories (recycling, compost, garbage) Compost Bin (with or without worms) Campus cleanup- picking up trash & sorting in appropriate categories (recycling, compost, garbage)

Key Teacher Demos/Activities:
Demo student activities (above) prior to having students complete the activities.

Common Student Misconceptions:
Students often assume that everything is trash. They do not understand that when you throw something away that it goes somewhere (it doesn't just disappear). Students to not understand that recycling changes "it" to something different (example: a bottle can become a bag or a park bench).

Things to Avoid/Correct:
Reusing is using the same item over again as what it is (refilling a water bottle). Recycling is changing the item into something else (see above misconceptions).
