multi colour beautiful flower colour changing expirement

I did this Experiment for my grade 5 science project. I thought it fit very nicely in with our rainbow theme. You will need glass jars/containers, food coloring and carnations. Just add food coloring to each jar and top with water. Place one carnation in each jar and let the food coloring do it's thing.

About 24 hours later you should get similar results as this:

My new camera is in the shop getting fixed. It was only 4 months old and it broke already! so sorry about the blurry pics I'm using our old, old camera until I get my new one back.


Jada loved watching the flowers change color "hey, what happen mommy?" So funny.

create a colourfull lava lamp

just like its store-bought cousins, this mesmerizing homemade lava lamp relies on a simple scientific fact: oil and water don't mix. When you pour both into a bottle, the denser water sinks to the bottom, leaving the oil on top. A store-bought lamp uses heat to propel the water up through the oil, but here the fizz from an antacid tablet triggers the frenetic action. The carbon dioxide bubbles shoot globules of colored water upward, and the globules drift back to the bottom as the bubbles disperse.

What you'll need

• Clear plastic bottle, cleaned and label removed (our is a 500-milliliter bottle)
• Vegetable oil
• Water
• Food coloring
• Pie pan
• Effervescent antacid tablets such as Alka-Seltzer

How to make it

1. Fill the bottle just over halfway with the oil, then add water, to an inch from the top. Add 10 drops of food coloring.
2. Place the bottle on the pie pan to catch potential spills. Cut or break an antacid tablet in quarters and drop one quarter into the bottle. When the bubbling slows, add another quarter-tablet to get it started again. (Adding too many tablets at once will cloud the oil with bubbles.)
3. To store the lamp, let the bottle sit until all the bubbles have completely dispersed. This prevents the buildup of gas in the bottle. Cap it and put it in a safe place to prevent spills.

water with out gravity

What goes up must come down right? Well try bending the rules a little with a cup of water that stays inside the glass when held upside down. You'll need the help of some cardboard and a little bit of air pressure.

What you'll need:

• A glass filled right to the top with water
• A piece of cardboard

Instructions:

1. Put the cardboard over the mouth of the glass, making sure that no air bubbles enter the glass as you hold onto the cardboard.
2. Turn the glass upside down (over a sink or outside until you get good).
3. Take away your hand holding the cardboard

What's happening?

If all goes to plan then the cardboard and water should stay put. Even though the cup of water is upside down the water stays in place, defying gravity! So why is this happening? With no air inside the glass, the air pressure from outside the glass is greater than the pressure of the water inside the glass. The extra air pressure manages to hold the cardboard in place, keeping you dry and your water where it should be, inside the glass.

Static electricity can be a problem whenever the humidity is low. It causes shocks and makes dust stick to surfaces, and it can literally make your hair stand on end. In this experiment, you will see that it also can move things around.
For this experiment you will need:

• a nylon comb
• a water faucet

Adjust the faucet to produce a small stream of water. The stream should be about 1.5 millimeters (1/16 inch) in diameter.

Run the comb through your hair several times. Slowly bring the teeth of the comb near the stream of water, about 8 to 10 centimeters (3 or 4 inches) below the faucet. When the teeth of the comb are about an inch or less away from the stream, the stream will bend toward the comb.

Move the comb closer to the stream. How does the distance between the stream and the comb affect how much the stream bends?

Run the comb through your hair several more times. Does the comb bend the stream more now?

Change the size of the stream by adjusting the faucet. Does the size of the stream affect how much the stream bends?

If you have other combs, you can try these to see if some bend the stream more than others.
Static electricity is the accumulation of an electrical charge in an object. The electrical charge develops when two objects are rubbed against one another. When the objects are rubbed together, some electrons (charged components of atoms) jump from one object to the other. The object that loses the electrons becomes positively charged, while the object that they jump to becomes negatively charged. The nature of the objects has a large effect on how many electrons move. This determines how large an electrical charge accumulates in the objects. Hair and nylon are particularly good at acquiring charge when they are rubbed together.

A charged object attract small particles, such as dust. The charge in the object causes a complementary charge to develop in something close to it. The complementary charge is attracted to the charged object. If the complementary charge forms on something tiny, such as dust particles, these tiny particles move to the charged object. This is why your television screen becomes dusty faster than the television cabinet. When a television operates, electrons fly from the back to the screen. These electrons cause the screen to become charged. The charge on the screen attracts dust.

The comb attracts the stream of water in the same way. The charge on the comb attracts the molecules of water in the stream. Because the molecules in the stream can be moved easily, the stream bends toward the comb.

When you comb your hair with a nylon comb, both the comb and your hair become charged. The comb and your hair acquire opposite charges. Because the individual hairs acquire the same charge, they repel each other. Perhaps you noticed that after running the nylon comb through your hair, the hairs on your head stood on end. This is a result of your hairs repelling each other because they are charged.

Static electricity is more of a problem when humidity is low. When humidity is high, most surfaces are coated with a thin film of water. When objects coated by a film of water are rubbed together, the water prevents electrons from jumping between the objects.

top 5 myths or unknown facts of science

1 Evolutionary Improvements

The Myth: Evolution causes something to go from “lower” to “higher”
While it is a fact that natural selection weeds out unhealthy genes from the gene pool, there are many cases where an imperfect organism has survived. Some examples of this are fungi, sharks, crayfish, and mosses – these have all remained essentially the same over a great period of time. These organisms are all sufficiently adapted to their environment to survive without improvement.
Other taxa have changed a lot, but not necessarily for the better. Some creatures have had their environments changed and their adaptations may not be as well suited to their new situation. Fitness is linked to their environment, not to progress.

2 Humans Pop In Space

The Myth: When exposed to the vacuum of space, the human body pops
This myth is the result of science fiction movies which use it to add excitement or drama to the plot. In fact, a human can survive for 15 – 30 seconds in outer space as long as they breathe out before the exposure (this prevents the lungs from bursting and sending air into the bloodstream). After 15 or so seconds, the lack of oxygen causes unconsciousness which eventually leads to death by asphyxiation.

3 Brightest Star

The Myth: Polaris is the brightest star in the northern hemisphere night sky
Sirius is actually brighter with a magnitude of ?1.47 compared to Polaris’ 1.97 (the lower the number the brighter the star). The importance of Polaris is that its position in the sky marks North – and for that reason it is also called the “North Star”. Polaris is the brightest star in the constellation Ursa Minor and, interestingly, is only the current North Star as pole stars change over time because stars exhibit a slow continuous drift with respect to the Earth’s axis.

4 Five Second Rule

The Myth: Food that drops on the floor is safe to eat if you pick it up within five seconds
This is utter bunkum which should be obvious to most readers. If there are germs on the floor and the food lands on them, they will immediately stick to the food. Having said that, eating germs and dirt is not always a bad thing as it helps us to develop a robust immune system. I prefer to have a “how-tasty-is-it” rule: if it is something really tasty, it can sit there for ten minutes for all I care – I will still eat it.

5 Dark side of the Moon

The Myth: There is a dark side of the moon
Actually – every part of the moon is illuminated at sometime by the sun. This misconception has come about because there is a side of the moon which is never visible to the earth. This is due to tidal locking; this is due to the fact that Earth’s gravitational pull on the moon is so immense that it can only show one face to us. Wikipedia puts it rather smartly thus: “Tidal locking occurs when the gravitational gradient makes one side of an astronomical body always face another; for example, one side of the Earth’s Moon always faces the Earth. A tidally locked body takes just as long to rotate around its own axis as it does to revolve around its partner. This synchronous rotation causes one hemisphere constantly to face the partner body.”

how to prepare flubber or jelly in 3 simple steps

Is it a solid – or a liquid? Flubber, immortalized by Disney in the 1997 Robin Williams flick and The Absent-Minded Professor back in 1961, has presented that very question to throngs of inquisitive young children, in southeast Michigan and else where, for decades. But all told, it's a very simple substance. And, with a little parent supervision, they can create it right in your family's kitchen!
For this cool craft, we flipped back to the 1999 edition of Metro Parent. In a roundup of young kids' fun called "Boredom Busters," we chatted up teacher Mary Buscemi of Webster Elementary School in Livonia, who used the stuff with her special education students.
"The kids love the sensory experience of it, the feeling, the smell," Buscemi explained. "They can be creative and make what they want." A favorite activity? Pretending to make "cookies" using cookie cutters that don't cut but leave an imprint. Kids would watch with fascination as the imprint faded and the Flubber oozes back in.
Here's her how-to!

Step 1

In a large container, such as a pail, combine:

• 1 cup warm water
• 2 cups white glue
• food coloring

Step 2

In a second smaller container, combine:

• 1 1/3 cups warm water
• 3 tsp. borax

Step 3

Mix ingredients in each container thoroughly. Pour contents of smaller container into larger container. Gently lift and turn the mixture until only about a tablespoon of liquid is left. Flubber will be sticky for a moment or two. Let excess liquid drip off. Flubber will then be ready. Store in an airtight container for about three weeks of use.
