This is a field investigation where students observe plants in a school forest setting. Students then compare adaptations of plants from different parts of the forest.
Plant growth regulators, including auxin, gibberellin, cytokinin, abscisic acid, and ethylene, are investigated in this learning activity to demonstrate how these chemicals (hormones) affect plant growth and development.
This original story about plants' dependence on the climate illustrates the theme of the issue of the online, free magazine Beyond Weather and the Water Cycle -- We Depend on Earth's Climate. The story is available at two reading levels, K-2 and 3-5. Four biomes are featured in a walk through a conservatory.
The topic of photosynthesis is a fundamental concept in biology, chemistry, and earth science. Educational studies have found that despite classroom presentations, most students retain their naive idea that a plant's mass is mostly derived from the soil, and not from the air. To call students' attention to this misconception, at the beginning of this lesson we will provide a surprising experimental result so that students will confront their mental mistake. Next, we will help students better envision photosynthesis by modeling where the atoms come from in this important process that produces food for the planet. This lesson can be completed in 50-60 minutes, with the students working on in-class activities during 20-25 minutes of the lesson. As a prerequisite, students need an introductory lesson on photosynthesis, something that includes the overall chemical equation. If students have already studied the intracellular photosynthetic process in detail, this video can still be very helpful because students often miss the big picture about photosynthesis. Materials needed include red, white and black LEGO bricks (described in downloadable hand-out) or strips of red, white and black paper plus paper clips (directions provided in downloadable hand-out). In addition to class discussions, the major in-class activity of this video involves the students' modeling with LEGO bricks or colored paper where the atoms come from in photosynthesis.
This lesson is a classroom and field-based activity where students learn about the parts of a flower through observation, journaling, and Observation.
This Lesson will examine the definition of Soil using written and video references. The lesson will also demonstrate how to identify different soil types by examining the texture of different soil samples. The lab portion will allow students to collect, evaluate and determine soil texture and type using the hands-on ribbon method. The lesson is meant to be conducted over a period of two to three days depending on class period length.
This lesson which nutrients plants need, how they are classified into macro- and micronutrients, and identifying plant nutrition in a crop field. Lesson and activity from Nebraska CASE Soybean Curriculum.
Students determine the necessity of water on plant survival and growth, consider varying needs for water throughout a plant’s growing season, and describe what happens to the plant when water is plentiful and when water is scarce. Lesson plan and activity from Nebraska CASE Soybean Curriculum.
Statewide dual credit (SDC) classes are college-level courses taught at the high-school level by trained high-school teachers. All SDC courses culminate in a challenge exam which is used to assess mastery of the postsecondary-level learning objectives. Students who meet or exceed the exam ‘cut score’ receive college credit that can be applied to any Tennessee public postsecondary institution. The SDC Introduction to Plant Science course includes the following content.introduction to basic plant forms, functions, reproduction and propagation, soils and mediums, plant nutrition, and plant injuries and controldemonstration of proper Integrated Pest Management practices and PPE usageidentification of plant classifications and uses with attention to nursery production and controlled environment production,discussion on the impact of plants and horticulture on people
