Learners use easily obtained materials to study ecological succession in a microbiological community. This investigation is appropriate for a variety of age groups. Elementary Students be fascinated by the changes occurring over time...

Students explore composting. In this composting lesson, students use compound microscopes to observe the microbial communities in compost. Observations and documentation of changes will occur over the course of several weeks.

Students learn more about lettuce. In this agriculture lesson plan, students listen to their instructor lecture about the history of lettuce. Students then participate in an activity that requires them to compare and contrast iceberg...

Students view a Reading Rainbow video on germs and discuss microbial diseases. They grow cultures of Staphylococcus aureus and then estimate and graph the count for their own bodies and those of the class.

Students are introduced to tree structure and use. They identify their special tree using all senses except sight. Students identify six different internal parts within a cross section of tree trunk (bark, phloem, xylem, cambium,...

Sixth graders create a type of notebook or journal using colored copy paper on which to take notes. They complete research on a certain disease and report on it and then design their own disease causing bacteria or virus. Finally, 6th...

Learners examine soil. In this science lesson plan, students recognize different populations in a soil sample, demonstrate and observe water and wind erosion, and construct a levee flood control technique.

Students study the structure of flowers. In this biology lesson plan, students observe the structure of a flower and find out what function each of the structures serve.

Students examine biological diversity and see how it relates to the concepts of variety and relative abundance.  In this investigative lesson students view a video on biodiversity and complete an activity. 

Students design a functional model of a coral reef ecosystem. In this coral reef activity, students identify the energy sources and material cycles of a coral reef. They write an essay about their niche in their own ecosystem.

Students discuss ancient plants and their adaption in the world. Students review forms of plant propagation. Given proper supplies and directions, students apply a variety of fern spores to peat pellets, monitor the growth, and...

Students study the natural incubation of hens and the important characteristics of the egg shell. They perform experiments to test the strength of the dome shape of an egg and prove that an eggshell has pores to allow air to pass. ...

In this flatworm worksheet, learners observe a flatworm in a petri dish. Students describe the flatwork and measure the planarian. Learners complete the various charts about the movement and observations of the planarian.

Students identify the major threats to coral reefs and the ways that they benefit from humans.  In this coral reef conservation lesson students create a public education program on coral reefs. 

Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...

Students observ the cooling and warming of room temperature, hot, and ice cold cans of water by measuring the change in temperature over time. They then attempt to develop explanations for the observations made and apply their findings...

Students examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...

Students investigate how trees produce their own food. They examine chlorophyll cells with a microscope, analyze a cross section of a log, determine how old the tree was, simulate the distance of the roots, and create a play.

Students make yogurt from powdered milk. In this yogurt experiment lesson, students combine powdered milk, warm water and plain yogurt. They mix up the ingredients and put it in an insulated cooler for 6-8 hours. 

Students study barrel sponges. For this science and art lesson, students discuss what sponges are, create their own sponge, and share what they created with the rest of the class.

Students define thermal equilibrium. They distinguish between internal energy and heat. Students describe how the quantity of heat that enters or leaves a substance is measured.

Pupils explore and explain how moon snails eat and where the holes in clamshells come from and then draw conclusion from the data collected. They incorporate math and graphing skills to determine if there is a relationship to a clam's...

Pupils recognize the presence of organic matter in soils from their immediate area and recognize which soil sample contains the highest concentration of organic matter.

Learners investigate the organisms of bacteria. They are given a culture of bacteria that can be observed under a microscope. The students make observations that are recorded. The lesson includes the mention of specific safety...
