The skill of observing involves using the senses, as appropriate, to find out about the characteristics, properties and attributes of objects, places and events.
The skill of displaying data involves organizing and presenting data collected during an inquiry in various visual forms for the purpose of summarizing results and deriving conclusions.
The skill of making conclusions involves connecting the data gathered in an inquiry back to the question and hypothesis that formed the basis of the inquiry.
Tomato plants belong to the plant group known as flowering plants or angiosperms. Flowers are important for reproduction and the production of seeds.
Because the ISS is dependent on Earth for its full life support needs, it is an open system. Scientists are working on creating a closed system using machinery and programs to recycle and reuse matter to maintain a supply of air, water, and food independent from Earth.
Eating is one of life’s great pleasures, even when orbiting 400 kilometres above the surface of the Earth. Learn how NASA is feeding today’s astronauts on the International Space Station (ISS) and see how they plan to feed tomorrow’s astronauts on a mission to Mars.

NASA Commentator Lori Meggs speaks to researchers about Advanced Plant experiments on the International Space Station, in which they have already learned a great deal—and gotten some interesting surprises—about how plants grow in space.
NASA Commentator Lori Meggs at the Marshall Space Flight Center speaks with Gioia Massa, project scientist for Veggie, a facility astronauts are using on the International Space Station to learn about how to grow lettuce and other vegetables in space, an ability which will be important in providing food for astronauts on future deep space exploration missions which cannot be resupplied from Earth.
This YouTube video, from Simple Science by Mark Drollinger, shows how controlled experiments are done using an example with plants.
This You Tube video, from SciExperiment Basics, explains how to identify and control variables in a scientific inquiry.
