Introduction: (Initial Observation)

Plants need water, light, air and also nutrients come grow. An alert that we didn’t speak food, we stated nutrients. Plants make their very own food. In order for the tree to survive and also grow, castle need small amount the nutrients. Such nutrients room usually easily accessible in water and soil.

You are watching: How does sugar water affect plant growth

Sugar is a product that is do from plants. Have you heard about sugar cane? the is the plant that produces lot’s of sugar. Various other plants produce sugar too, however in much lower amounts.


So what wake up if we offer sugar water come plant? go it aid the tree to grow more? or it will hurt the plant and disable it’s potential of making it’s very own food. This is the subject of our project and we room going to do some experiment to discover out.

Information Gathering:

Find out around sugar and also plants. Review books, magazines or ask experts who might know in order come learn around the impact of sugar on plants. Save track of whereby you got your info from. Internet can be a great source the information around plants.

While you carry out your search, friend will find out that nutrient for tree are likewise known as fertilizers. Girlfriend may additionally learn around different varieties of fertilizers. Organic fertilizers are made from other plants and animals. Not natural fertilizers room special chemistry or a combination of those chemicals developed in chemical factories.

Following room samples of info that you may find:

How to care for reduced flowers?

First, before you put the flowers in a vase, reduced the stems. Host the stems underwater, and use a sharp knife to cut them ~ above the diagonal. Don’t usage dull scissors due to the fact that they have the right to crush the stem and prevent the flower from soaking up as much water as they need. Make sure to remove all the leaves and thorns that will be underwater in the vase. Leaves under the water line can reason bacteria and algae come form.

Next, prepare the water. Most flowers like lukewarm water, although feather flowers (such as tulips, irises, and also daffodils) survive best in ice-cold water. A floral preservative can help the flowers last longer. You have the right to use a store-bought preventive or make her own. Part recipes mix lemon v a tiny bleach, when others introduce a teaspoon of sugar and a few drops of bleach. However, some professionals advise versus any residence concoctions due to the fact that they don’t carry out the facility mixture that nutrients and also preservatives that cut flowers must survive.

Once her bouquet is in the vase, keep it the end of straight sunlight and place that in a cool spot. Eliminate flowers as they wilt so lock don’t contaminate the rest of the bouquet. Change the water at the very least every 2 or three days, if not daily. Make sure to add much more preservative come the water every time, and you have the right to re-cut the trunk to allow the flowers to absorb much more water.

What’s in those small packets the florists give you?When a flower is cut from the mom plant, the is separated from its life support system. Just like an astronaut without a temporary life support mechanism — it’s in trouble. Thus, nearly all advertisement floral preventive contain the an easy components the the life support system for the reduced flower: a biocide (explained below), an acidifier, and also sugar.

Biocides are chemicals that kill the bacteria, yeasts and fungi the feed top top the sap the seeps native the cut flower stem. It’s an remarkable sequence of events: You cut a increased stem and place that in a vase that water. Bacteria begin to grow, and also within 3 hours, there space 30 million bacteria in the vase! this bacteria plug the tiny straw-tubes that conduct water to the flower. Together a result, buds fail come open, necks weaken and bend, and also leaves wilt. The mountain helps water relocate up the stem more easily and the sugar acts together a flower food.

Put a coin in the vase: Wives’ tale or genuine solution?

If you don’t choose to use chemicals to prolong the life that your reduced flowers, there space “natural” alternatives. Some approaches work better than others. Here’s one for you: does a penny and also an aspirin tablet computer placed in the vase water yes, really do any type of good? part say the mix does keep flowers new longer. The concept is the the copper acts a fungicide and the aspirin renders the water much more acidic. Here are much more food + acid combinations:

Add one component lemon-lime soda (not diet) to 3 components water. Climate to each quart of this solution, add 1/4 tespoon bleach. Thereafter, add 1/4 teaspoon bleach after every 4 days of use.To 1 quart water include 2 tablespoons fresh lemon juice, 1 tablespoon sugar, and also 1/2 teaspoon bleach.Add 2 ounces Listerine mouthwash per gallon the water. Listerine has sucrose (food) and a bactericide. Listerine is acidic and is said help water move up the cut stem.

Question/ Purpose:

What execute you desire to uncover out? compose a explain that describes what you want to do. Usage your observations and questions to create the statement.

The purpose of this project is to determine the impact of sugar on plant growth.

Identify Variables:

When friend think you recognize what variables might be involved, think around ways to readjust one in ~ a time. If friend change much more than one in ~ a time, you will certainly not understand what variable is causing your observation. Occasionally variables room linked and work with each other to cause something. In ~ first, shot to choose variables the you think act independently of every other.

Variable the may influence the plant expansion in our task is the lot of sugar that we add to the water. In other words the result of sugar water on plants varies based on the concentration of street in street water that we use.


Based on her gathered information, make an educated guess around what varieties of things influence the system you space working with. Identifying variables is necessary prior to you can make a hypothesis.

My hypothesis is the sugar will have actually no impact on plant growth. It may likewise harm the tree by attracting insects. My reason for this theory is the sugar is not known as fertilizer and also is not being marketed in garden supplies.

Experiment Design:

Design one experiment come test each hypothesis. Make a step-by-step perform of what you will execute to answer each question. This list is referred to as an experimental procedure. Because that an experiment to give answers you can trust, it must have a “control.” A manage is an additional experimental psychological or run. It is a separate experiment, done specifically like the others. The only distinction is the no speculative variables space changed. A manage is a neutral “reference point” because that comparison that permits you to check out what an altering a variable does by compare it to not changing anything. Trusted controls room sometimes an extremely hard come develop. They have the right to be the hardest component of a project. Without a control you can not be sure that an altering the variable causes your observations. A collection of experiment that consists of a regulate is called a “controlled experiment.”

In stimulate to test the effect of sugar water on tree growth, we do two different experiments. In one experiment we plant some seeds and test the street water top top seedlings or young plants.

In the other experiment us use bigger plants such as inexpensive houseplants to test the effect of sugar water.

Experiment 1:

You will need:

1. Three Styrofoam cup or tiny clay pots2. Dirt, potting soil etc.3. 15 Bean seeds (5 because that each cup or pot)4. Water5. Sugar6. Journal (Note book)


Fill the cups/pots with soil about half way. Plant the seeds. Cover through soil till the pots are around three-quarters full.Water and place all plants alongside a window, where they deserve to get sufficient light.Seeds will certainly germinate in around 5 days.Get one cup of water and include one spoon complete sugar and also stir till sugar completely dissolves. Brand it low sugar water.Get one more cup that water and add two spoon complete sugar and also stir till sugar fully dissolves. Label it high sugar water.Get another cup that water through no street on that. Label it just water.When your young plant is prepared (this takes around 2 to 4 weeks depending upon weather, light and also water) climate you can start your last stage of your experiment as follows.Label her plants v “Control”, “low sugar” and also “High sugar”. This labels represent the street water the you room going to usage for that plant. You will use just water for control.Water her plants with water and also sugar water in cups as neededObserve the transforms on plants every day, measure the elevation of plant and also record the results. In your observation look for any type of signs of expansion or any signs of defect in plant.Repeat this if necessary for around 15 days or until you watch a change.Record the outcomes in a table showing the height of each plant.

Plant elevation table:

Start dateAfter 7 daysAfter 14 daysAfter 21 days
Control Plant
Low sugar plant
High street plant

Make a graph:

You may make a bar graph come visually existing your results. Do 3 vertical bars and also name them “Control Plant”, “Low street plant”, and also “High sugar plant”. The height of each bar need to represent the plant development in the length of her experiment (21 days).

Experiment 2:

Procedure:Find or purchase 5 same size green plants of any kind.Label your plants v “Control”, “low sugar” and also “High sugar”. These labels stand for the concentration street water that you space going to usage for that plant. Girlfriend will use water instead of street water for control.water the plants v water, low sugar water and high street water (prepare lock as explained in vault experiment)Observe the alters on plants every day and also record the results.Repeat this if needed for approximately 21 days.Record the outcomes in a table reflecting the elevation of plant after certain number of days.

Take photo from her experiments and also make illustrations if needed. Usage your plants and pictures together a part of your display.

Results of Experiment (Observation):

Record the results of her experiment 1 in tables choose this for each experiment:

Start dateAfter 7 daysAfter 14 daysAfter 21 days
Control Plant
Low street plant
High street plant

If you are using reduced flowers, make everyday observations.

Summary the Results:

Summarize what happened. This deserve to be in the kind of a table of processed numerical data, or graphs. It could additionally be a composed statement that what arisen during experiments.

It is indigenous calculations using videotaped data that tables and graphs space made. Studying tables and graphs, we deserve to see trends that tell us how different variables reason our observations. Based on these trends, us can attract conclusions about the mechanism under study. This conclusions assist us check or refuse our original hypothesis. Often, mathematical equations deserve to be made from graphs. These equations enable us come predict how a readjust will impact the system without the should do added experiments. Progressed levels of experimental science rely heavily on graphical and mathematical analysis of data. In ~ this level, science becomes even more interesting and powerful.


Using the trends in your speculative data and your speculative observations, try to price your initial questions. Is your hypothesis correct? now is the moment to pull with each other what happened, and also assess the experiment you did.

Related inquiries & Answers:

What you have learned may enable you to answer other questions. Many questions are related. Several brand-new questions may have emerged to you while law experiments. You may now have the ability to understand or verify points that you discovered when gathering information for the project. Concerns lead to more questions, which lead to extr hypothesis that need to be tested.

Possible Errors:

If friend did no observe anything different than what taken place with her control, the variable you readjusted may not affect the system you space investigating. If friend did no observe a consistent, reproducible trend in your collection of speculative runs there might be speculative errors affecting her results. The an initial thing to examine is how you are making her measurements. Is the measurement an approach questionable or unreliable? perhaps you are analysis a range incorrectly, or perhaps the measuring instrument is functioning erratically.

If you determine that experimental errors are influencing your results, closely rethink the design of your experiments. Review each action of the procedure to find sources of potential errors. If possible, have actually a scientist testimonial the procedure with you. Occasionally the designer of one experiment deserve to miss the obvious.
