Weather is an important factor in human comfort. Who has wanted to trade a 100-degree, full sun scorcher for an overcast 75-degree day with a breeze for an outdoor sports tournament? Or hoping for a warm, sunny day at the beach instead of a thunderstorm?
Before the advent of modern air conditioning, snow and ice were the main ways to keep cool on hot days. In the summer and in warmer climates, ice was a luxury used to cool drinks and cool bodies in the same way refrigeration and air conditioning are used today.
In 2016, the Food and Drug Administration (FDA) updated the requirements for food labels leaving manufacturers several years to comply. As a result there may be two different food labels on the products around classrooms, lunchrooms, and homes. Both labels have the same information about food, but the format differs slightly.
Gary Anderson created a recycling symbol in 1970. The three arrows broadly represent the three tenets: recycle, reduce, reuse. They form a continuous circle (more accurately, triangle) representing the ideal of sustainability.
Grocery stores don’t think the ugly produce sells, so they don’t buy it, meaning farmers have to get rid of it. Approximately 20% of all U.S. produce never enters the market but ends up left in the field or transported to landfills.
Humans have used dams since ancient Egyptian and Mesopotamian civilizations restricted the flow of rivers and the extent of floods with earth and mason structures. Either simple or complex, the purpose of the dam is to control the flow of water.
Even in places where it is easy to recycle because of school-wide or community-wide initiatives, many people are confused about what and where to recycle. Students can help other students by creating instructive visual signage for waste collection areas.
Students bring their lunch to school for lots of reasons, dislike of school food, special diet, to fit in with other kids, etc. Many times at home, parents have the greatest of intentions when making or purchasing the food that goes into those lunches.
This activity focuses on the “reuse” theme of reduce-reuse-recycle. Students collect waste materials (paper, bottles, cans, cardboard tubes, fabric, etc) and find other uses for them either practically, for a school project, or as art objects.
Students have the opportunity to become part of the “recycle” process by breaking down used paper and recreating a new, usable product from the waste. This activity can be messy, as students produce paper pulp and then dry it to new sheets of paper.
Students may watch the garbage people come by and think that their waste magically disappears. Some may have been to the dump with a parent and some may have a compost pile or “dump” of their own on their land.
