In this episode of #AskAbby, we are so excited to have special guests join Astronaut Abby to discuss how plants will be cultivated on Mars!
The Infographic Creator learning strategy introduces students to a method of presenting data, as well as other information, from an inquiry in a visually interesting, graphic format called an infographic.
Students will make a CD Case Germination Viewer to germinate tomato seeds and make daily observations to practice their skills of observation and recording to explore the process of germination.
Students will conduct a basic guided inquiry to determine the mass of water in a tomato. Students will consider the value of using dried food in the context of meeting human needs in space and as a food preservation technique.
Students use a variety of sources of information to compare the physical characteristics of Mars to the physical characteristics of Earth. Students will use a Venn diagram to organize information and determine what similarities exist between these two planets. Students then consider the implications of the physical characteristics of Mars vs. Earth in terms of the challenges to overcome in preparing for a human interplanetary mission to Mars.
Students will be introduced to the leaf structures of dicots and their role in gas exchange. Students will collaborate to perform an inquiry in which they follow a simple procedure to collect leaf cells samples and compare leaf structures from different plants.
Although we often hear Mars is quite similar to Earth, it's also radically different. These differences will provide some serious challenges for landing a human mission there and sustaining life, challenges which are covered among these facts on Mars.(9:14 min.)
People have always dreamed of exploring the universe and colonizing other planets. In the vastness of space, Mars, sometimes called 'The Red Planet', seemed like the closest planet to Earth, orbiting the sun, that could potentially sustain life and humans. But what is Mars actually like? Is it really that similar to Earth? Get ready to travel through space as we compare Earth to Mars and see how they stack up against each other.
This animation looks at a basic physical comparison of the Earth with our closest neighbor, Mars. (2:48 min.)
Learn the basics about Paper and Thin Layer Chromatography. What is Chromatography and why is it done?
Discover the hormones that dictate whether a plant grows downwards with gravity, towards water and nutrients, or upwards towards light.
Astronauts traveling to Mars will need to grow some of their own food in order to survive and stay healthy. But on Mars will there be enough light to meet the needs of growing plants?
Is is possible to produce food to eat and air to breathe while in space? The short answer: it's not easy, but it can be done.
Air is made up of nitrogen (78%) and oxygen (21%) with small amounts of other gases such as argon and carbon dioxide. It probably then comes as no surprise that nitrogen is important for all organisms as it helps them to live and grow.
Most people do not think twice about soil, but we could not live without it. The plants we eat, and the plants that feed the animals we eat, depend on soil. Plant roots need soil for physical support. Plants also get nutrients from soil, which they need for healthy growth and development. Future astronauts on a long-term mission to Mars will want to grow some food crops to add to their diet of packaged food.
