NASA KSNN What do plants need to grow?
By definition, a plant is a living thing that produces its own food through photosynthesis. This process uses carbon dioxide and water. Trapping light from the Sun, plants are able to change sunlight's energy into useable chemical energy. Not only is chemical energy produced, but oxygen is a by-product of photosynthesis. Plants are essential to the balance of life on Earth - and to life, as we know it, on other planets.

Macro to Micro Structures
This program deals with the conceptualization of micro processes and environments. It involves teaching chemistry through macro phenomena, which can be observed, and micro processes, which occur on the molecular level, and can only be imagined. Conceptual change must occur in order for students to understand chemical phenomena. Teaching for conceptual change poses a grea
Chemistry and the Environment
This program introduces the chemistry of the environment. It addresses selected topics such as water quality and purification, recycling, and the hole in the ozone layer. Bringing the students to awareness of these topics helps them understand important issues in the world around them. In studying chemistry, environmental studies or anything else, the classroom climate i
The concept of speed is introduced to the inertia-mass relationship. Concept: Force varies with mass and rate of change of speed. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.
Subtracting Mixed Numbers
Students learn to subtract mixed numbers. Instructor uses a whiteboard for demonstation. She shows students how to change the fraction so that they can solve the problem.
This excellent video is accompanied by text and is suitable for high school students. "Earl Warren served as chief justice of the Supreme Court from 1953 to 1969. During this time, America experienced great change and turmoil, especially regarding civil rights. Warren believed it was the job of the Court to shape the moral and civil liberties by which the nation should grow in the second half of the twentieth century. Many of the Warren Court's rulings reflected that opinion. Some of his most re
Toys From the Future
The Inventables guys, Zach Kaplan and Keith Schacht, demo some amazing new materials and how we might use them. Look for squishy magnets, odor-detecting ink, "dry" liquid and a very surprising 10-foot pole. Keith Schacht co-founded Inventables, a hothouse for innovation. More recently he's brought us the JobCoin listings board, the Freshwater Venture entrepreneur map, and Facebook's Grow-a-Gift. The video challenges you to look for the unexpected and to change the way you view things. This c
Emily Brontë, Wuthering Heights: Symbols
In this video symbols that are used by Emily Brontë to help her tell her story in the novel Wuthering Heights are examined. Brontë uses recurring images to help us understand her characters better and to provide social comments about the time in which she lived and wrote. The significance of windows and eyes, doors and locks, books and education, death and, finally, sickness are examined. The most important issue to consider is that of boundaries. This normally suggests some sort of chan
Machining Parameters: Grinding
Through this simulation, students can change the parameters of a grinding wheel and explore the effects of those changes.
Our World: Honeybees
Join NASA scientists and beekeepers in a citizen science project to collect important data about climate change. Learn how honeybees pollinate over 130 crops in the United States each year and what NASA is doing to help study the decline in bee populations. (05:47)
2.1 Nutrient budgeting
The extreme challenges of life in the polar regions require the animals who make their habitat there to make many adaptations. This unit explores the polar climate and how animals like reindeer, polar bears, penguins, sea life and even humans manage to survive there. It looks at the adaptations to physiological proceses, the environmental effects on diet, activity and fecundity, and contrasts the strategies of aquatic and land-based animals in surviving in this extreme habitat. This unit builds
Natural Inquirer Journals: Facts to the Future
The articles in this Natural Inquirer include just a few of the renewable natural resources studied by USDA Forest Service scientists. By reading these articles, you will learn about the condition of the resources in the year 2000, and you will learn what might happen to them by the year 2040. In the year 2040, how old will you be? Do you think that the condition of the Nation's renewable natural resources will be important to our society in 2040? Why or why not? The articles in this journal wil

How to Grow a Sweet Potato Plant
In this clip learn how to grow a sweet potato plant, also known as ipomoea. A gardener gives historical information about the sweet potato and explains how to plant it in a lush, warm climate while providing plenty of moisture to keep the soil damp. A growing tip is to avoid cold weather exposure when growing sweet potato vines.
Managing Change in Small Primary Schools
This is the summary of a fuller research report on change management in small primary schools throughout Scotland. The research was funded by the Scottish Office Education and Industry Department (SOEID) and conducted in 1996/97 for the Scottish Council for Research in Education (SCRE). Evidence is drawn from two phases: a postal survey sent to all headteachers of small Scottish primary schools (those with less than 120 pupils) and subsequent case studies of 18 of these headteachers. The purpose
Frontal Lobes and Behavior: The Story of Phineas Gage
This module relates the story of Phineas Gage, whose name appears in virtually every general psychology textbook. After a heavy metal rod was blown through his temporal lobe, Phineas experienced dramatic mental change. The study of the trauma and its physiological effects provided the first documented evidence of how brain injury can affect human behavior.
