The purpose of this experiment is to test different types of water to see whether in affects the growth on plants.
Hypothesis - I believe that rainwater and bore water will cause the plants to grow most effectively as these types of water are natural (with no added chemicals) of which the plants are used to.
The independentvariable is the water. The water will be changed weekly in order to give the plant fresh water (of the same type). For example: if I was using Bore water for this experiment, I would empty out the water in the container weekly and put fresh Bore water in weekly. If I keep this consistency, I should end up with reasonable results.
The Dependantvariable is the plant. The plant will be measured every science lesson (in centimetres) to see how healthy and quickly the plant is growing, compared with other water types (such as rainwater, distilled water etc).
My suitable control(of a type of water) will be Bore water. I will be able to compare the results that I end up with, with the other members in my group that are using rainwater (Renee), Tap water (Molly) and Distilled water (Caitlin). I believe that my suitable control will best be compared with these types of water due to the differences of chemicals or natural vitamins and nutrients.
The following factors will remain constant:
· Soil - The same soil will be used throughout the whole experiment and will not be changed.
· Water type - Although the water will be changed weekly, the same type of water will be kept constant throughout the whole experiment and will not be changed.
· Container - The container used for the experiment will be kept constant throughout the whole experiment and will not be changed.
· Plant - Although the plant will grow in size, the type of plant (Vinca) will remain the same throughout the whole practical experiment and will not be changed.
Method of Practical Experiment
1. Find four two litre bottles (one per group member) and cut each bottle in half.
2. Get a rubber cork (that contains a hole) and thread a small piece of string through the hole.
3. Tightly push the cork into the spout of the bottle.
4. Turn the top half of the bottle upside-down and fill it with soil.
5. Plant a small 'Vinca' plant into the soil.
6. Repeat this process with the three other bottles.
7. Fill the bottom half of each bottle with the suitable control/specified type of water (Bore water, rainwater, tap water and distilled water).
8. Place the top half of the bottle (which contains the plant) into the bottom half of the bottle (which contains the specified type of water) of each bottle.
9. Each group member must label their plant with their name and the type of water contained so that everyone may tell them apart.
10. The setup process is complete and the plants will now have to be measured each science lesson (to see how healthy, fast and well the plants are growing depending on the specified type of water) and recorded in a table of results.
11. Empty and refill the water (of the correct type) in each container weekly.

Over time, the plants grew and the size sand amount of leaves increased. There were no real obvious patterns, trends or relationships between in the results.
The results show that the hypothesis was correct. The Bore Water experiment grew the healthiest at the fastest rate with many flowers fully formed. Although the rainwater experiment did not grow as many flowers, it still managed to get up to the same height as the Bore Water experiment. The healthy and fast rates of growth was firstly the Bore Water plant which grew from 9 ½ cm up to 18cm. Secondly the rainwater plant which grew from 8 ½ cm up to 18cm (but did not form as many leaves or flowers at the Bore water experiment). Both the Tap Water and Distilled water experiments started at 6cm and grew up to 15cm, but the Tap water experiment grew 2 more flower buds than the Distilled water experiment.
The type of water does affect plant growth, although this experiment was not completely reliable. Certain aspects of the experiments were not measured. The method is reliable but needs to be made sure that it is followed correctly. Also, the controls of variables were valid, so the unreliability of this experiment does not depend on the variables. The data and table of results are missing particular measurements, which makes it difficult to get reliable results.
The design of the experiment was accurate and reliable.

Does different dirt affect the growth of a plant?
Yes, different types of soil can affect the growth of a plant. Factors such as nutrient content, pH levels, drainage, and texture of the soil can impact a plant's ability to absorb water and nutrients. It's important to choose soil that is suitable for the specific needs of the plant species you are growing.

Which influences the rate of a plant growth in different types of plants?
Factors such as light intensity, temperature, water availability, soil nutrients, and genetic makeup can influence the rate of plant growth in different types of plants. Different plants may have different requirements for optimal growth, so it is important to provide the right conditions for each specific plant species.

They do not, but the more light, the more photosynthesis
What is the question that Maria and Elena want to answer by perfoming an experiment?
Maria and Elena want to determine how different soil types affect plant growth. Their experiment aims to compare the growth rates of plants in various soil conditions to see which type promotes the healthiest and fastest growth. By systematically varying the soil types, they hope to identify the optimal conditions for plant development.
What are some good science project questions?
How does the type of soil affect plant growth? Does the angle of sunlight affect the rate of photosynthesis in plants? How does the pH level of water affect the growth of aquatic plants? What is the effect of different types of music on human heart rate? How does the temperature of water affect the rate of ice melting?
How do different types of liquids affect fruit- fly growth?
Different types of liquids can affect fruit fly growth differently, depending on their nutrient content and pH levels. Sugary liquids like fruit juice can promote fruit fly growth due to the high sugar content, while acidic liquids like vinegar may discourage growth. It is important to provide a balanced diet for fruit flies to ensure optimal growth and reproduction.
