What plants are good for science fair projects?
The key for a good science fair plant is that it grows quickly, allowing experimentation to be carried out over the shortest period of time possible.
- Cress.
- Herbs.
- Mushrooms.
- Beans.
- Vegetables.
- Grass.
- Bulbs.
Do plants grow towards light science project?
Seeds push little leaves up from the ground into the light. A house plant in a dark room will grow toward the light. Sunlight reduces auxin, so the areas of the plant that are exposed to sunlight will have less auxin. The areas on the dark side of the plant will have more auxin.
Why is NASA interested in plants?
Veggie’s purpose is to help NASA study plant growth in microgravity, while adding fresh food to the astronauts’ diet and enhancing happiness and well-being on the orbiting laboratory. In the absence of gravity, plants use other environmental factors, such as light, to orient and guide growth.
Can plants grow on Mars?
Unlike Earth’s soil, which is humid and rich in nutrients and microorganisms that support plant growth, Mars is covered with regolith. Plants on Earth have evolved for hundreds of millions of years and are adapted to terrestrial conditions, but they will not grow well on Mars.
What foods would be most difficult to eat in space and why?
Salt and pepper are available but only in a liquid form. This is because astronauts can’t sprinkle salt and pepper on their food in space. The salt and pepper would simply float away. There is a danger they could clog air vents, contaminate equipment or get stuck in an astronaut’s eyes, mouth or nose.
Can u fart in space?
On Earth, farts are typically no big deal — smelly, harmless, and they quickly dissipate. But if you’re an astronaut, every fart is a ticking time bomb. The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go.
What foods can you not eat in space?
Here are five foods that NASA Astronauts can’t eat in space:
- Bread. U.S. Food and Drug Administration.
- Alcohol. United States Embassy, Berlin.
- Salt and Pepper. Getty Images / iStock.
- Soda. Getty Images / iStock.
- Astronaut Ice Cream.
Do you feel hungry in space?
Astronauts may have plenty of food to eat, but being in space can put a damper on their appetites. Without gravity, food aromas waft away before they make it to the nose. When you can’t smell food very well, you can’t really taste it, either.
How do female astronauts deal with their periods?
A combined oral contraceptive, or the pill, used continuously (without taking a week off to induce menstrual flow) is currently the best and safest choice for astronauts who prefer not to menstruate during missions, says Varsha Jain, a gynecologist and visiting professor at King’s College London.
How many days on Earth is a year in space?
365 days
Can we return from Mars?
Return to Earth Spacecraft returning from Mars will have re-entry velocities from 47,000km/h to 54,000km/h, depending on the orbit they use to arrive at Earth. They could slow down into low orbit around Earth to around 28,800km/h before entering our atmosphere but — you guessed it — they’d need extra fuel to do that.
How does space change the human body?
Without the proper diet and exercise routine, astronauts also lose muscle mass in microgravity faster than they would on Earth. Moreover, the fluids in the body shift upward to the head in microgravity, which may put pressure on the eyes and cause vision problems.
Can we live on Mars?
However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen. Human survival on Mars would require living in artificial Mars habitats with complex life-support systems.
