it is called the control of the experiment

Get your bulb, it should be a very small wattage (weak) one, get your battery and wires, connect one wire to plus side of abttery and other wire to minus side of battery, then connect to the bulb, you may have to play around a bit to find a connection that produces light.

A volleyball is softer than a soccer ball.

Dry garbage is manufactured goods that do not decompose easily such as metal, glass, and plastic.

While recycling is available for most forms of dry garbage, and composting of wet garbage can be done quite easily at home, most garbage, wet and dry, are disposed of via municipal and private waste contractors. It is typically buried in landfills, incinerated in large furnaces, or dumped at sea

It dies because it does not have any salt to breath in making it too weak and leave it at its corpse.

Yes you can plastic. Many "plastic" shopping bags are now made from rice. Their life is fairly short and they disintegrate completely, so saving real plastic bags from polluting our world.

With 10-speed I assume you have two chainwheels up front and five sprockets at the rear, although today you could have one chainwheel at the front and 10 sprockets at the rear as well.

There's really no way of telling how many teeth you have short of actually counting them, but probably between 48-53 on the big ring and about 10 less on the small ring. Chainwheels are available in just about any number of teeth counts.

If your a student just talk to a teacher or head teacher theyd be happy to answer your questions.

Well, I do not know what the criteria is for your science fair project but you could do something like:

# Does gender affect the ability to do a good cartwheel? # Does age affect the ability to do a good cartwheel? # Does height affect the ability to do a good cartwheel?

yes it will because it is not heavy it is light

try testing serving ways....try at least 10 people and that should help!

Tennis balls bounce because the air pressure inside is higher than the outside pressure. They begin to lose bounce as soon as removed from their pressure can. The alititude where the ball is played will affect the bounce. As they are played, they lose more bounce. Typically, they lose too much bounce to play after about 3 sets of recreational (amateur) tennis, or 8 games of professional tennis.

The average player can hit a ball to anywhere between 80 and 100 km/h, and flick to between 60 and 80lm/h. Most internationals can hit much faster than that (~110- 120km/h), and some dragflick faster e.g. Taeke Taekema can dragflick at about 120-125km/h on a good day.

The Earth has been facing immense pollution from our garbage and consumption. The latest deadly pollution is plastic bags that fill up the landfills. With plastic bags becoming a growing concern, cotton bag has become the new way to help stop the pollution. With plastic bag pollution being a rising concern, many shoppers need to start using reusable cotton bags in order to stop the pollution. Plastic bag pollution is very deadly and takes hundreds of years to break down. Even if the component is broken done, the deadly chemicals will go into the ground and water system. By reducing the usage of plastic bag, Earth can recuperate. That's why cotton bags should be used world wide to help reduce the pollution. It is our generation to stop the pollution and start using cotton bags as the solution. With global warming going out of hand from gas exhaustion, we don't need any more problems especially plastic bags that are harmful when broken down naturally. These broken down elements cause sickness and destruction to the air, soil and water system. Use cotton canvas bags starting today as a way to stop the plastic pollution that is becoming a major threat to the environment. Our lives are threatened ever more from the growing usage of plastic bags. It is time you bring a canvas bag to shopping the next time you go to a supermarket.

Non-biodegradable materials are things that can't be broken down easily by natural processes. For example, plastic shopping bags would take thousands of years to be degraded (broken down).

Some examples of non-biodegradable materials are:

plastic

polystyrene (styrofoam)

metals

foams

glasses

silicon-based materials/circuit boards

oil

ashes

It depends on what form of racing, the restriction is the rules.

limiting displacement, boost (if even allowed), type of fuel allowed.

The down force package the engineers/crew want to run(depending on the curcuit ). If they require a restrictor plate manditory like super speedways in Nascar. FYI they would easily be running 240-250mph if unrestricted.

I have used regular laundry bleach to whiten deer sculls. if you have acess to a beauty shop buy some 40% volume bleach gel.boil the skull/bones until all flesh is removed.now apply the gel to skull/bones with a light brush(like a tooth brush but larger) let sit for a few hours, keeping it moist with gel,until desired color is achieved.

yes

conclusion

The group that is not exposed to the tested variable is called the control group. This group serves as a baseline for comparison, allowing researchers to determine the effects of the variable being tested. By comparing outcomes between the control group and the experimental group (which is exposed to the variable), researchers can better understand the variable's impact.

Scientists make observations to help them make a hypothesis or collect data during an experiment. Observations involve using the senses to gather information about the natural world. These observations serve as the foundation for formulating a hypothesis, which is a testable explanation for a phenomenon. By carefully observing and recording data, scientists can analyze and draw conclusions based on evidence.
