Biomes are sub-environments where plants and animals sustain one another. Fifth grade students may designs their own miniature biomes and observe how environmental changes affect the wildlife inside. Have students create a butterfly biome by placing some caterpillar eggs in a jar and offering the caterpillars fresh food when they hatch. Once the caterpillars turn into butterflies the students can release them into the wild. Students can also create a water biome with a fish tank filled with pond water. Place some pond stones at the bottom of the tank and plant water plants. Get some guppies from the pet store and introduce them into the tank.
A great and inexpensive project for your class sends the students home to dig in their trash. Challenge students to create the best invention possible using recycled or reused items. Some great ideas include a milk gallon bird feeder, a soda bottle fish tank or an egg carton planter. Have each student bring her project to class and give a presentation on what she created.
If your kids are having trouble understanding what an environment actually encompasses, it is time for a field trip. Take the students out to the nearest park and find a guide to walk your class through the environment, explaining some of the interesting aspects. For instance, if your school is in southern Arizona, have the students hike the nearest mountain with your guide pointing out the various plants and animals.
Get your kids excited about green energy by offering them a chance to design and run their own green energy business. Encourage students to research various cars that manufacturers are creating and the work that has gone into their creation. For an added math influence, limit the students with factors such as market demands and a production budget.
