This Computer Algebra System (CAS) activity encourages students to investigate addition, subtraction, and multiplication of matrices. They find the inverse of a matrix. Students also solve a set of linear equations by using matrices.
A well done tutorial in muscle structure and function, all in Spanish.
In this lesson, students will get to know the candidates running for president and where they stand on important issues. They will create a flow chart documenting the steps a candidate must take to be elected. Then they will conduct research to create a profile of a specific candidate and his/her qualifications, point-of-view on various topics, and their Presidential campaign. They will present their candidate profile projects to classmates and follow the progress of their campaign.
Molly and Trini discover that it's important to question the reliability of informational texts, in this animated 11-minute story from the PBS Kids series Molly of Denali. [25:25]
Observe how the Moon appears to change in the sky over time in this GBH lesson plan. Students will observe and use evidence from media to describe and record how the Moon appears to change. The media in this lesson plan includes a digital storybook and a video of the Moon in the sky at different times.
What makes a healthy media choice? We all make choices every day about the media we consume and create. But do kids understand what makes a media choice healthy or not? Hint: It's about more than just screen time. Use the activities in this lesson to give kids a framework for making informed media choices. Approximately 45 mins.
LESSON OBJECTIVES: Learn the "What? When? How Much?" framework for describing their media choices. Use this framework and their emotional responses to evaluate how healthy different types of media choices are. Begin to develop their own definition of a healthy media balance.
This activity will introduce you to the Fujita scale for rating tornado strength. You will then put your knowledge to use by observing photographs of tornado damage and assigning them a rating.

Imagine having a microscopic camera so small that you could travel inside a cell. This interactive site allows you to do just that. Click on any one of eight individual parts of the cell--cell membrane, nucleus, DNA, RNA, ribosome, protein, endoplasmic reticulum, or mitochondria--and learn its function and appearance.
Students apply their understanding of the natural water cycle and the urban "stormwater" water cycle, as well as the processes involved in both cycles to hypothesize how the flow of water is affected by altering precipitation. Student groups consider different precipitation scenarios based on both intensity and duration. Once hypotheses and specific experimental steps are developed, students use both a natural water cycle model and an urban water cycle model to test their hypotheses. To conclude, students explain their results, tapping their knowledge of both cycles and the importance of using models to predict water flow in civil and environmental engineering designs. The natural water cycle model is made in advance by the teacher, using simple supplies; a minor adjustment to the model easily turns it into the urban water cycle model.
Through an overview of the components of the hydrologic cycle and the important roles they play in the design of engineered systems, students' awareness of the world's limited fresh water resources is heightened. The hydrologic cycle affects everyone and is the single most critical component to life on Earth. Students examine in detail the water cycle components and phase transitions, and then learn how water moves through the human-made urban environment. This urban "stormwater" water cycle is influenced by the pervasive existence of impervious surfaces that limit the amount of infiltration, resulting in high levels of stormwater runoff, limited groundwater replenishment and reduced groundwater flow. Students show their understanding of the process by writing a description of the path of a water droplet through the urban water cycle, from the droplet's point of view. The lesson lays the groundwork for rest of the unit, so students can begin to think about what they might do to modify the urban "stormwater" water cycle so that it functions more like the natural water cycle. A PowerPoint® presentation and handout are provided.
Real-life examples, interactive headline and image games and brief explanations make this an attractive site for learning to recognize media bias.
Counting from one to one hundred is simple when you follow this concise lesson that explores number patterns and counting. This lesson includes two related interactive games that are easy to grasp and provide immediate feedback.
