Why do you like to do plant experiments?
I love doing plant experiments and sprouting seeds with young children in the spring. Not only do they get excited to see how plants grow but planting seeds also teaches them patience and how to wait for gratification which is very important in this fast-paced, instant gratification world in which we now live.
What do plants need to grow fast?
In particular, plants need nitrogen, phosphorus and potassium. When dissolved in water, these nutrients get absorbed by a plant’s roots. If a plant can’t get the nutrients it needs from the soil, fertilizer can help. Fertilizer provides plants with essential nutrients and helps them grow faster.
Why is it important to teach children about plants?
It also teaches them about the needs of plants and develops patience because they have to wait for the results and observe changes over time. A fun option that I like to do is put faces on the cups or containers and have the grass be the face’s hair.
Can You Just Add a few nutrients and make plants grow?
“The fact that you can just simply add a few of those nutrients and still get the plants to grow, as a geologist, I don’t think I would have expected that,” he said.

What was Boyle famous for?
Known for his law of gases, Boyle was a 17th-century pioneer of modern chemistry. Every general-chemistry student learns of Robert Boyle (1627–1691) as the person who discovered that the volume of a gas decreases with increasing pressure and vice versa—the famous Boyle's law.
What did Jan Ingenhousz discover?
Jan Ingenhousz is yet another scientist who contributed to the discovery of photosynthesis. He was a Dutch chemist, biologist and physiologist who performed important experiments in the late 1770s that proved that plants produce oxygen. Ingenhousz placed submerged plants in sunlight and then in the shade.
What did Aristotle discover about photosynthesis?
Aristotle proposes that plants, like animals, require food. Anticipates Priestley's work 2000 years later by asserting that plants do not require animals but animals require plants. Theophrastus writes that plants obtain their nourishment through the roots.
What are the five things that plants need to survive?
Almost all plants need these five things to survive: Light. Air. Water. Nutrients. Space to grow. Most plants need light, water, air, nutrients and space to grow in order to survive (©2020 Let’s Talk Science).
Why do plants grow so slowly?
If a plant doesn’t receive enough light, it will grow very slowly. But too much light can cause the plant and the soil it lives in to dry out. Different plants have different light requirements. Some need bright or direct light. Others can thrive in dimmer or indirect light.
Why are radish sprouts so thin?
These radish sprouts are very tall and thin because they are competing for resources (Source: akiyoko via iStockphoto ). Without enough water, nutrients and light, plants can grow tall and thin or short and stunted. Overcrowded plants tend to be less healthy, which makes them more likely to suffer from disease.
Why do plants need water?
Plants need water for photosynthesis. Absorbed by the roots, water travels through a plant’s stems to the chloroplasts in the leaves. Water also helps move nutrients from the soil into the plant. Too little water can cause a plant to wilt or droop. Too much water can cause a plant’s roots to rot.
What are the nutrients that plants need?
Nutrients are substances that nourish a plant. In particular, plants need nitrogen, phosphorus and potassium. When dissolved in water, these nutrients get absorbed by a plant’s roots. If a plant can’t get the nutrients it needs from the soil, fertilizer can help.
How do plants make glucose?
But they can also grow in artificial light. Plants use light energy to make a type of sugar called glucose. They use glucose as their energy source. Plants make glucose in a part of their leaf cells called the chloroplast. Each chloroplast contains a green pigment called chlorophyll.
Do all plants need light?
Almost all plants need light to survive but there are a few special exceptions. Some parasitic plants like the corpse lily do not have chlorophyll and only get their energy by stealing it from other plants.
Why do plants have ligins?
Lignins in plants have functions whose closest analogy is that of bones in humans. They give structure and rigidity to plants and the means to stand upright against gravity. We already know space causes bone and muscle loss in humans because the physical demands are lower in space.

What is an APH plant?
The Advanced Plant Habitat (APH), like Veggie, is a growth chamber on station for plant research. It uses LED lights and a porous clay substrate with controlled release fertilizer to deliver water, nutrients and oxygen to the plant roots.
What is the chemical reaction in a plant cell?
Normal chemistry in the cells makes a very reactive oxygen-based chemical. Uncontrolled, this “reactive oxygen species” can react with the machinery that repairs DNA and mess that up, or it can damage mitochondria. In a healthy plant, the cells have ways of dealing with it. But in space, plants are making more of it.
Why do plants need light?
Plants need light to grow because it is an important part of photosynthesis, the process plants use to convert carbon dioxide and water into food. Without light, photosynthesis does not work properly and therefore the plant does not get enough food. However, not all plants need the same amount of sunlight.
What is the process of water moving up a plant's xylem?
Capillary action is the process in which a liquid, like water, moves up something solid, like the tubes (xylem) in the stem. The leaves help pull the water up the xylem through transpiration. The leaves have little holes that let out the water that the plant is done using.
How to color celery stalks?
Cut about an inch or so off the bottom of the celery stalks. Fill each container about halfway with water and drop 10-15 drops of food coloring in each glass. Place the celery stalks in the water. I also like to do a split stalk one.

Why do plants have filigree roots?
On Earth, plants produce a filigree-like pattern of roots, as they grow away from their seeds in search of nutrients. Scientists had long assumed the movements were influenced, in part, by the force of gravity. On the International Space Station, roots exhibited the same pattern, without gravity as a guide.
When did plants start blooming in space?
The first to flourish in space was Arabidopsis thaliana, a spindly plant with white flowers, in 1982, aboard Salyut, a now defunct Russian space station.
