Students observe the effect of croos contamination as they inoculate orange juice with penicillin mold from the refrigeration lab and active yeast solution from the sterilization lab. They experience a simulation of passing bacteria...

Learners explore the exponential growth and decay of microbial populations in relation to the organism tolerance ranges in their environment, They observe the impact of changing variables which can affect microbial populations.

Learners observe the changes seen in succession and the biodiversity of a community through its species richness and evenness. They create a dung culture in a clear plastic cup from horse, goat or cow dung then observe the numbers of...

Students investigate evolution in its most fundamental form: the observation of living organisms. By comparing variations that exist among living animals, students formulate their own hypotheses and conclusions about the evolution of...

Each student plants two lima beans in a plastic cup with a paper towel so they can be observed growing. The beans are misted with a spray bottle, and placed in a warm sunny area. Students view the beans each day for the next two weeks,...

Third graders observe light as a form of energy, that it can be reflected/bounced, refracted/bent and absorbed. They explore how different types of light affect our lives as a whole. Songs are researched that involve light (ex. "You...

In this nature worksheet, students observe 6 different fruits. Students cut each fruit in half and study the seeds inside. Students record their observations and practice writing the fruit names.

For this desert adaptations worksheet, students are given a water filled sponge which represents an animal. Students observe their "animal" for a 24 hour period and conserve the water in the sponge as best they can. They measure and...

Students observe how bird flight and machine flight are similar. In this aerodynamics lesson, students observe how birds fly and the shapes of their wings, and investigate how observing birds helped develop the concept of machine flight....

Students complete an experiment using wire screening, wires, water, sand, and food coloring to compare the relationship of groundwater to wells. In this water lesson plan, students observe and record what they see after they complete the...

Students investigate the 3 states of matter. For this physical science "matter" lesson, students observe and participate in a number of demonstrations involving melting and freezing water. Students observe the effect heat has on changing...

Third graders investigate Newton's law of Motion.  In this chemical reaction lesson, 3rd graders participate in an experiment with rockets to study Newton's law. Students observe the effects of a chemical reaction made by combining...

First graders discover the effects of global warming on polar bears. In this life science instructional activity, 1st graders model the polar bear's habitat and observe what happens as they raise the temperature. They record their...

In this unit, the students explore basic ecology concepts and scientific processes using spiders as model organisms. They capture spiders, observe and care for them, and use them to answer their own questions about spider behavior....

Students investigate the characteristics and nature of yeast and molds help to explain how these microorganisms affect food production. They experiment with yeast in sourdough in preparing sourdough pancakes.

Learners investigate the water cycle. They observe a demonstration of the water cycle involving ice, water, bowls, and steam, explore various websites, and listen to the book, "The Magic School Bus: Wet All Over: A Book About the Water...

Students consider that under certain conditions in nature tend to remain the same or move toward a balance. They observe populations and determine the functions (e.g., de-composers, producers, consumers) they serve in an ecosystem. They...

Students explore the light spectrum. The teacher uses holographic diffraction grafting film on an overhead to demonstrate the true nature of color. After observing a vivid rainbow, students recognize that white light is composed of all...

Students practice techniques of field observation and data-gathering while studying local bird population, describe ecosystem as complex combination of elements, which can affect or be affected by each other, and determine effects of...

Students become familiar with the variables that control Earth's solar energy supply. They explore the source and nature of solar energy, the genesis of radiation, and the structrue of the Sun, gas spectra are observed and sample...

Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.

Learners construct and observe a model of two different types of wetlands. In this wetlands lesson, students create a model of a wetland with constant drainage and a wetland that maintains a well-saturated soil. Learners observe and...

Students visit the park to observe signs of spring in the forest and pond environments.  In this field trip lesson, students explore the park for various items

Students observe and gather data from a model simulated home.  In this efficiency lesson students examine the factors that influence energy efficiency, complete a lab activity then draw conclusions from their data.
