Pupils investigate data and recyclable materials. In this math lesson, students save recyclable materials and create a graph of the materials. Pupils discuss how they could help the environment by recycling.

Students discover that recycling is using a product more than once so that natural resources can be saved and so that we won't need so many garbage dumps and landfills. They see that there are different ways to recycle. Students design a...

In this activity students explore earth-friendly materials that can be used in home environments. They learn about the relationship between the environment and design, and use a variety of problem-solving strategies. They work in...

Students develop a working model computer program of a recycling center addressing the material management, work schedules and business finances of running the recycling center.

Students discuss what happens to trash after it is collected. They sort "clean" trash into groups depending on whether it should be recycled, incinerated, placed in a landfill, composted or if it is something we could avoid using.

Students collect data. In this math instructional activity, students collect data about recyclable materials. Students develop a plan that will help the environment. Recycling plastic containers is discussed.

Students develop a working model computer program of a recycling center which can be used to make decisions about a school recycling program.

Students relate recycling to waste reduction. In this science lesson, students talk about the environment and how recycling certain natural resources actually saves on energy.  They also discuss what type of recycling causes...

Learners examine the importance of recycling to help the environment. In groups, they make a compost bin on the school grounds recording how the material changes from week to week. They collect other materials for recycling like cell...

Students determine the percentage increase in output of solid waste in the U.S. They determine the length of time it takes for throw away items to decompose.

Plastic math? Have young learners count and name the number of plastic items in their centers. Kindergartners match sight word cards to the number of plastics in a given group, while learning that plastics come in all different shapes,...

Students investigate how to reduce, recycle, and reuse items in order to conserve natural resources. They complete a trash graphing activity after discussing different types of trash. Finally, the examine ways to buy recycled products to...

Students explore the amount of waste produced by humans. For this ecology lesson, students predict which lunch bag and its contents will produce the most waste. Leftover material is examined, amounts are recorded, and a bar graph is...

Students brainstorm reasons for politicians to expand recycling programs and find statistics to support recycling programs. They design posters, displaying a compelling statistic about recycling, to convince students at their school to...

Students share their knowledge about aluminum and aluminum recycling by sharing the information with the rest of the community.

Students investigate solid waste. For this environmental lesson, students collect their own garbage for a day and analyze the weight and the percentage of recyclable items in their trash.

Youngsters learn how "hand-me-downs" can help save money while practicing math word problems with this fun learning center activity.

Students examine how riding a bike can impact the environment and cut down on carbon emissions.  In this environmental lesson students design a bike rack that is made from recycled material.

Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

Students evaluate trash. In this Science lesson, students collect and weigh trash from their classrooms. Students categorize the trash and the corresponding weights, recording the information on a data sheet.

Students label boxes and sort trash into those items that can be recycled, composted, incinerated or taken to the landfill.

Students separate plastics according to their densities, develop a method for separation and identify variables in an experiment and a fair test, changing only one variable at a time for a fair comparison. After testing, they develop a...
