Soil type (use one type of soil buy same type and make sure you have enough) IV. Sunlight (make sure plants are getting same amount of light put them in same spot same position) V. The pot (use same size pots same color pots) Part II: Designing an Experiment For the second part of your assignment, you get to apply the scientific method to a real life situation. Just as you saw within the lesson, the steps of the scientific method can be used to address the problem of finding the best directions to the movie theater, figuring out how to get grass to grow in your lawn, determining what color light helps plants grow fastest, or answering a variety of other questions. Think about a scenario or problem that could occur in your life in which you can apply the scientific method to answer the question or solve the problem. Explain how you would follow each step of the scientific method and design an experiment.
The type of soil- using the same type of soil will allow the plants to have no other reason to grow differently iv. How much light reaches the plant- keeping the plants in relatively the same area so that they can get approximately the same amount of light allows for accuracy as well v. Type of light- putting the plants under the same type of light, whether it be sunlight or artificial, will promote accuracy Part 2: Purpose: I want to investigate the way to keep fresh cut flowers last the longest. Research: I would research other ways that people have found out about flowers. You could find a florist's website with how to take care of fresh flowers and compare in your experiment to how a blogger says that the flowers stay fresh the longest. Hypothesis: “I believe that the florist's suggestion of using their floral conditioner will cause the flowers to last longer
Brief Explanation This experiment will test the effect of caffeine on the growth of mung bean plants. By testing this, I can also prove the effect of caffeine on all other organisms. The experiment could go either way: the plants with caffeine could grow more or they could stop growing once I add the caffeine in to the equation. * Independent and Dependent Variables * The independent variables are the watering solutions which are water, caffeine solution, and coffee mixture. The constants are the size of the pot, the concentration of caffeine and coffee, the amount of sunlight, the temperature of the environment (which will remain at room temperature) and the amount of water added daily.
What tools you will need? 3. What are the benefits of gardening? D.

Most people enjoy fresh foods, so how can you not benefit from planting your own garden? I’m aware that not everyone enjoys eating vegetables, but most people can appreciate flavor.
T. Aestivum Growth with Environmental Contaminate Ammonium Hydroxide INTRODUCTION People use household cleaners such as ammonia hydroxide every day and are told that they are safe and diluted to a point that it will not cause any harm when exposed to these chemical. These household cleaners are disposed like water down drains which end up in the city’s rivers and lakes. The purpose of this experiment is to determine if the contaminate ammonium hydroxide has any environmental impact. Our hypothesis was that seeds subjected with more than .5ml of the environmental contaminate ammonium hydroxide will not show growth of the plant T. aestivum. MATERIALS AND METHODS In order to determine if seeds subjected with more then .5ml of the environmental contaminate ammonium hydroxide will not show growth of the plant T.aestivum, some items are needed.
Place the petri dishes in a sealed plastic bag, taking care to not shift the seeds too much. 6. Check on the seeds daily to see if the seeds need more water. If so, spray each dish with its appropriate salt water concentration. 7.
1. Type of plant- use all the same seed type 2. How much water is used on each plant- give each plant the same amount of water; measure it 3. How much sunlight- place each plant in an open area with no shady spots that could skew the experiment 4. Type of soil- use the same soil and don’t add anything to it 5.
You can also clearly see the sepals on the new buds. The African violet can be propagated by placing a whole leaf in soil covering the leaf only about one third of the way up. Once planted treat it the same as the parent plant by keeping it watered and in indirect sunlight. Works Cited "African violet". Encyclopædia Britannica.
Label boiling tubes with concentration of sucrose solution Take measurements of each potato tube (mass) on the balance and record in a suitable table. Always use the same balance to weigh the mass of the each tube as measurements may differ slightly between scales. The surface area of the potato tubes will be kept the same by having all the tubes the same size. They must be kept the same because the amount of surface area exposed to the solution may affect the rate of osmosis. Be sure to note which strength solution is put in each.
Let me tell you how inorganic food starts. As many people know about organic food is that it is natural and free of toxins. Let us take fruits and vegetables for instance, they start from a seed unless it has been genetically modified for better quality and taste. This seed is planted and watered until the seed has reached to the surface and that is when it is feed with nutrients that are comprised of chemicals, which means the plant is no longer organic. This inorganic fertilizer gives all the nutrients the plant needs to grow which causes the plant to grow more rapidly and produces the fruits and vegetables quickly.
