In this activity, the learner explores various ways in which organisms reproduce. The learner discusses the role that reproduction plays in the cycle of life. By watching short videos and participating in follow-up discussion: 1. They observe that no individual organism lives forever and in order to continue species, organisms must pass their genetic instructions on to the next generation. 2. They learn that organisms reproduce asexually, by dividing and producing two identical copies of themselves. 3. They learn that many plants reproduce sexually, often using complex strategies that have evolved over millions of years. 4. They explore the pros and cons of asexual and sexual reproduction and the reasons both strategies persist.

This video aims to provide an illustrative lesson about the respiratory system in birds and how the adaptations of that system over time have made it different than that of other living creatures, especially mammals. Birds are omnipresent in our lives, and students will come to understand and appreciate the fascinating inner workings of these beautiful creatures. This lesson discusses avian features and differences for 20 to 25 minutes, with approximately 20 minutes of in-class student activities.

This art history video discussion examines Jusepe (Jose) de Ribera's "The Martyrdom of Saint Philip", 1639, oil on canvas (Museo Nacional del Prado, Madrid). The English Romantic poet, Lord Byron , wrote that the artist, "Spagnoletto [the little Spaniard] tainted/His brush with all the blood of all the sainted" (Don Juan , xiii. 71).
This art history video discussion examines Auguste Rodin's "The Gates of Hell" …
This art history video discussion examines Auguste Rodin's "The Gates of Hell" 1880-1917, plaster (Musee d'Orsay, Paris).When the building, earlier on the site of the Musee d'Orsay in Paris, was destroyed by fire during the Commune in 1871, plans were drawn up to replace it with a museum of decorative arts. Rodin won the competition to design a great set of doors for its entry way. Although the museum was never built, Rodin continued to work on the doors. They became an ongoing project; a grand stage for his sculptural ideas. It's fitting that the plaster of this great unfinished sculpture, The Gates of Hell, is now on display at the d'Orsay, the former railway terminal that was built on this site instead of the museum of decorative arts and that, by lovely coincidence, was converted into one of the world's great art museums.

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.
