Have you ever wondered how those colored carnations got their hues? You can make different colored flowers that are unique from all others. All you need to do is purchase the flower you want.
What you need:
• White colored flowers (rose or carnation)
• Water
• Pair of scissors
• Food coloring
• Small cups
How you do it:
1. Pick the colors you want for your flowers.
2. Get your cups and pour water in them.
3. Drop your chosen colors into each cup or water. Just a few drops will not do. Make sure that the water becomes dark. This will give you the desired effect.4. Get your pair of scissors and cut a centimeter off the bottom of the stem.
5. Immerse the stem into one of the cups, which you filled with colored water.6. Wait about twenty-four hours. [Sometimes the colors appear after just a few hours. Others take at least one to two days.
*** If you want to create multicolored flowers, ask an adult to split the stem with a sharp razor. Dip the two or three divisions into different colors. This will produce a multicolored flower.The process behind this coloring effect in flowers is called transpiration. Transpiration is a process through which a plant absorbs water through its stem. When the water reaches the flowers and leaves, it evaporates through certain openings calls stomata. During evaporation, a pressure forms. This pressure pulls in more water into the plant. It is like a tree sips through a straw. On a hot day, some trees can transpire gallons of water. Light, wind, temperature, and humidity are the factors that affect the rate at which a plant transpires.
A plant transpires faster when there is a bright light. This happens because the stomata open much wider, allowing more carbon dioxide into every leaf. Carbon dioxide is one of the ingredients in photosynthesis.
In higher temperatures, transpiration is quicker. This is brought about by faster diffusion and evaporation.
When the environment is windy, the diffusion of water vapor from the leaves is also quicker. This results in faster transpiration.
In humid conditions, transpiration is slower. Once the leaves are surrounded by moist air, the diffusion of water vapor from the leaves slows down. -
When you have too many seasonal fruits in your kitchen, you often want to taste them all at the same time. There are times when you pick a bunch of them and peel them all at the same time for convenient eating. Yet, have you ever thought that peeling the fruit removes its first layer of protection?
Like other organic substances, fruits need protection, even if they are still up in their trees. Once they are a picked, they start to deteriorate because they lose their living connection of nutrients. Their skin delays their deterioration.
Before you start this experiment, consider the many factors that contribute to the deterioration of fruits:
• Microorganisms
• Excess moisture
• Exposure to oxygen
• Extreme temperaturesWhen a fruit starts to rot, it breaks down into simpler substances. This is the process of decomposition. It is nature’s way of recycling, which is imperative to keep matter in biome. In the natural world, the faster something decomposes, the better. This is because all the raw materials are returned to the soil much quicker. Once in the soil, other organisms can start using them immediately.
The Question stated:
Does peeling a fruit make it rot more quickly?
What you need:
• Two each of the following
o Oranges
o Apples
o Strawberries
o Peaches
• Pen and paper for your notes
• Knife
• Small plastic bagsHow you do it:
*** Note that this experiment yields the best results during winter. There are usually no bugs during this time of year.
1. Take one of each fruit and cut it in two. Place them in small plastic bags.
2. Take each of the whole fruit and place them in separate plastic bags.
3. Observe the process of decomposition that happens daily.
4. Note which of the fruits starts to rot first.
5. Make a record of your observations with the use of a chart.REFERENCE LINK: https://www.education.com/science-fair/article/does-opening-fruit-up-cause-it-to-rot-faster/

[wp_ad_camp_2]As a parent it’s imperative that your child has fun at school and develops a love for learning that lasts a lifetime. The best way to do this is by getting your child involved in science from a young age with the help of a few easy science projects for kids.
Not only will kids love the hands-on experience it offers them, but they will also love how the projects get their creative juices flowing and soon desire to explore more about the world of science! Here are a few such science projects for your kids to do that are simple, but will get them hooked on the beautiful world of science!
- 1. Create Salt Crystals
Crystals exist everywhere. They are in your salt, pencils and even your jewelry. So what can be more exciting to a child than growing their own crystals? There’s not much you need to grow crystals besides water, salt, a little patience and some time!
Make a salt solution by filling a cup with warm water and adding salt to it until the water will not dissolve any more salt. You will know you reached that limit when the salt just drops to the bottom and sits there. Now pour some of this solution on a saucer and let it sit for a while. The salt crystals form as the water evaporates and keep growing as you pour saltwater onto the saucer.
- 2. Grow Sugar Crystals
Another fun Crystal growing technique is to do exactly the same as above, except use sugar. Once you have a super saturated solution of water and sugar (same thing as saying the hot water you used to dissolve the sugar will not dissolve anymore of it and the sugar just sits on the bottom). Now tie a string to a pencil and make the string just long enough to almost reach the bottom of the cup or glass. Set the pencil on the top of the cup and make sure the string hangs down into the sugary liquid. Set it aside and look at it every couple of hours. You will see the sugar crystals begin to form on that string. After a day or two, you should be able to pull the string out and look more closely at the crystal formations. And what’s cool about this project is you can eat that crystal when you’re done!
And if you want to do even more on crystals, here are two other projects. But you will have to help a bit more on these … Make a crystal geode, and more home made crystals.
- 3. Understanding Water Tension
Small insects can walk on water because of water tension, which you can show to your child through experiments using a glass, some water, a paperclip and some pennies. Fill a glass with water and drop the clip into it. Let it drop to the bottom, pull it out and gently lay it on the water. If done correctly, the paperclip floats on top of the water.
The second experiment involves filling the glass with water and then carefully adding a few pennies to the glass, one at a time. The water starts rising over the glass in a dome shape, without spilling out. You can teach your child how a drop of dish soap can disrupt water tension when the water tension ‘breaks’ on adding the dish soap, and water starts spilling over the glass edges.
See! These experiments are not only easy to conduct; they are preformed using everyday things any child can find and use at home!
