This interactive animation shows the user the process of meiosis and the changes a cell undergoes at each stage of cell division. The resource does allow one to view meiosis as a continuous sequence or stop at any stage and review critical events taking place during each stage.
This lesson exposes children to a variety of animals and guides them through observation of animal similarities, differences, and environmental adaptations. This lesson can be used as part of a study of plants and animals. Before doing the lesson, students should know the meanings of the terms plant, animal, and living.
Students will come to understand that in sexually reproducing organisms, such as humans, typically half of the genes come from each parent. Students will examine a fictional pedigree and determine which gene is responsible for a given trait. The genetic information for individuals is depicted as a jigsaw puzzle.
This content resource builds students' knowledge and conceptual understanding about plants through interactive activities, printable worksheets, and hands-on explorations. There are six investigation cases for students to complete; each case examines a different aspect of plant life, including plant structures, life cycles and reproduction, proper environmental conditions for growth, and ecological importance. Supplemental background information and a teacher's guide with suggestions for using the materials in the classroom are also provided. A Spanish version of the web site is available.
Students will become familiar with written workplace communication documents. They will understand how a memo is set up and how memos improve performance on the job and increase awareness in their community.
Students will learn and practice the life-saving skill of performing the Heimlich maneuver.
In this lesson students will identify the plant parts involved in reproduction, identify the animal (bee) structures involved in pollination, and demonstrate how pollen moves from the male stamen to the female stigma. The lesson closes with a discussion about the benefits to both the bee and the plant in the pollination process. Note: This is the first lesson in a 3-lesson series; each lesson can be used independently.
In this lesson students will explore the links between pollination and food production. The lesson concludes with a discussion about the importance of bees in pollination. Note: This is the first lesson in a 3-lesson series; each lesson can be used independently.
In this lesson students will describe the complementary relationships between pollinators and the plants they pollinate, and to identify adaptations that flowers have developed to encourage pollination. Note: This is the first lesson in a 3-lesson series; each lesson can be used independently.
In this hands-on activity students sort a soil sample. They will observe the basic components of soil and relate the components to plant growth.
An interactive clock that will allow you to change the time in whatever minute/hour intervals you want. It will also give the digital and analog time simultaneously.
Students practice telling time on five-minute intervals on both analog and digital clocks. Class activities, learning center activities, and worksheets are provided.
Students practice telling time on the hour and half-hour on both analog and digital clocks. Learning center activities and worksheets are provided.
This lesson is a general introduction to clocks and telling time. Students practice telling time on the hour on both analog and digital clocks. Class activities, learning center activities, and worksheets are provided.
The activities in Underground Adventure guide students through an outdoor field study of soil life and some of the variables that affect soil biodiversity. Through these activities, students will gain experience in scientific skills such as hypothesis, observation, and inference. When done together as a unit of study, the activities are designed to help students answer this research question: What is the relationship between the soil's physical properties, environmental and human factors, and soil biodiversity?
Students will choose a topic to research that relates to their career path and write paper on that career in Microsoft Word using MLA formatting for the report.
In this activity students model the cycles of matter by creating an ecosystem in a jar and observing how it changes over time. Students will also research the nitrogen, water, and carbon cycles and prepare presentations to share information with their peers.
