Students conduct various experiments to investigate plant transpiration. In this biology lesson plan, students explain how this process helps maintain the hydrologic cycle. They measure the rate of water loss in plants using a potometer.

Students identify various parts of plants and determine which parts people eat. They conduct a celery stalk experiment in which they determine the value and use of the stem, and how it helps the plant to meet its needs. Students use a...

Students investigate equilibrium in erosion and deposition by predicting effects of moving water on soil; modeling an erosion simulation; observing results of a test; inferring causes and effects, and hypothesizing about erosion variables.

Students identify the essential elements needed for promoting wildlife habitat. They describe the terms used in habitat design and the shelter for wildlife. Students explore how to create a pond to support wildlife and how to create a...

Expose the beautiful mystery of bulbs as young botanists learn all about these fascinating plants. They glean information from a short text before observing actual bulbs (consider an onion), and comparing their findings with predictions....

Explore water transport in plant stems using this fun experiment! Your scientists will start by reading Stems by Vijaya Bodach. Then, activate prior knowledge about plant stem functions and water transportation....

Young geologists learn how to use an identification key in order to classify rocks. The key is designed to help them classify rocks into three types: ignesous, metamorphic, and sediimentary. After an initial teacher-led demonstration,...

Students inspect soil erosion. In this soil erosion lesson, students examine the causes of soil erosion and discover ways to conserve the landscape.

Middle schoolers investigate organisms by searching soil on their school ground.  For this insect life lesson, students utilize field guides to help identify the organisms found in a rotting log on their campus.  Middle...

Students formulate their own hypothesis, determine which variables are important to test their hypothesis, design an experiment in which they collect data. They utilize instruments and tools to measure, calculate, and organize data.

Students simulate some of the Pathfinder experiments by devising methods of collecting and measuring magnetic substances in pseudo-Martian soil. The efficiency of each of the methods used to collect materials is evaluated in this lesson.

Students monitor streams, take stream surveys, collect chemical and macro-invertebrate and stream discharge data. Using a digital camera, students observe the percentage of various types of vegetation on the flood plan, riparian area and...

Students develop a list of actions they could perform that would protect our water resources from pollution. They formulate hypotheses, conduct experiments and draw conclusions about actual pollutants found in our water supply.

Students work cooperatively using the democratic process to select a place for a park. They identify how the garden in the park will look. They write a five paragraph essay as an assessment.

Middle schoolers examine the way that many place names in Arkansas came to be. By looking at Arkansas highway maps, they find names that come from the characteristics of each of the state's six geographical divisions. This interesting...

Students engage in a lesson plan which demonstrates the importance of rocks, soils and minerals in engineering and how using the right material for the right job is important. The students build three different sand castles and test them...

Learners investigate the process of hydroponic agriculture. They grow beans in different hydroponic solutions, compare results and graph their observations.

Fourth graders make predictions, observe, collect and record data. They investigate several soil and worm websites. Finally, 4th graders write a letter to The President which defends earthworms by explaining their value to the United...

Learners investigate the types of waste created by people and identify various options for trash disposal. They read and discuss a handout about what a landfill is and the different types of trash, match types of trash with the proper...

Second graders investigate rice farming. In this farming equipment lesson, 2nd graders discover what type of equipment is needed to get rice farms ready to plant. Students gain knowledge about what a combine does and how it is important...

Students simulate the search for water in Mars using simple apparatus. For this space science lesson, students explain how soil temperature affects the cooling of probes. They graph the data collected from the simulation.

Young scholars conduct an experiment to observe photolysis in the lab. In this chemistry lesson, students explain the mechanism behind photolysis. They test the impact of a non-toxic marker to plant metabolism.

Fourth graders experiment with different varieties of plants and draw conclusions after performing a series of lab activities. A very helpful student worksheet is given. This is a nicely done introductory lesson for life science.

Students investigate how plants grow in different biomes. In this biomes lesson plan, students plant sees of impatiens, lima beans and rye seeds in egg cartons. When the plants begin to grow they simulate the assigned biome conditions...
