The other "Three Rs" are covered in this lesson: reduce, reuse, and recycle. Over four weeks, conservationists collect data about waste in their own homes. They combine their findings with those of other students in order to analyze...

Students create a worm bin full of fruit and vegetable scraps wit paper and observe what happens over time. In this decomposers lesson plan, students observe that the fruit and vegetable scraps become new soil.

Here is an extremely simplistic look at food chains and webs. It depicts three different food chains, each containing a plant, plant eater, and meat-eater. Learners fill in the missing part of each chain by using the images provided at...

students discuss the importance of light and the consequences of living without it. Using a plant as a demonstration, students predict and observe what happens to a plant when it does not receive enough light. In groups, they experiment...

Students explore decomposition. Students define and describe  components of the decomposition process. Students make a composter in a terrarium. Students record observations and changes weekly, drawing conclusions about the results...

Students visit the UBC Farm. In this instructional activity on various landscapes, students spend a day at the University of British Columbia exploring the farm and trail adjoining the campus. This instructional activity could be...

Students investigate microscopic life by viewing video clips.  In this organisms lesson, students view photographs and video clips on the internet of micro-organisms and discuss the harms and benefits of the creatures. ...

Students observe earth science by participating in a planting activity. In this seeds activity, students identify the process for seeds to transform into plants which eventually produce food. Students sow seeds in the ground and...

Students identify biodegradable items. In this environmental lesson, students participate in a game of tag. A student's name is called out along with a biodegradable item and the student is tossed a ball.

Students investigate methods of decomposition in order to make compost. In this decomposition science lesson, students set up compost bags using food and materials which decay over time. The initial lesson is approximately 30 minutes,...

Students perform an experiment to find out if plants grow best when grown in soil with no fertilizer, with chemical fertilizers, or with compost that they have made themselves. Students discover how agriculture practices can benefit the...

Students explore Earth science by completing a plant art project. In this botany lesson, students utilize tights and soil to create a furry, grassy puppet style animal from cress seeds. Students cut off the excess cress after several...

In this researching the nutrient cycle worksheet, students read about the cycle of nutrients, look at the diagram, then answer two questions by doing research on this topic.

Students study four types of soil and predict which one worms would use for their habitat. They observe worms in each type of soil and monitor their activity. They create class charts highlighting their discoveries.

Students conduct an experiment to demonstrate how fruit fly populations are controlled by spiders. They observe a variety of environments with fruit flies and spiders and consider how vital spiders are to controlling the insect population.

Students determine the differences between reusable, compostable and recyclable trash.

Students explore vermi-composting. In this vermi-composting lesson, students listen to the story Diary of a Worm and discuss the parts of a worm. They create worm bins and add organic food for the worms to recycle. 

Third graders examine the difference between composting and wasting food. They problem-solve what to do about leftovers after lunches so good food doesn't go to waste.They study food storage techniques that are environmentally friendly...

Learners play a game based on concentration or memory to place recyclable items into one of 4 groups. In this recycling lesson, students work in groups of 1-4 to place cards with pictures of various items into a Composting, Recycling,...

Students work together to discover the relationship between water holding and drainage characteristics of soils. They record their observations and discuss the results. They examine particle size and pore sizes as well.

Students make plant pots out of newspaper as part of a recycle, reuse, and reduce lesson. In this recycling lesson, students fold a piece of newspaper to make a pot in which to start plants. They fill it with compost and plant seeds.

Learners present information about recycling to other students. In this environmental protection lesson, learners create a puppet show or commercial about the importance of recycling for other students to view.

Students explore the effect of the earths rotation and its relationship to the suns position and the effect that the longer and shorter amount of daylight has on a pumpkin plant which they have planted.

Students define trash, garbage, or solid waste, discuss ways of disposing of trash, list examples of biodegradable materials, and have trash relay race in order to sort trash into appropriate containers labeled biodegradable, reusable,...
