Science Experiments
Experiments often conducted by students to test different scientific theories and hypotheses
11,111 Questions
An experiment is when you find an answer to a question that you asked. You need some materals and steps that you have to follow. For example, maybe you asked,"How do you make an egg float in water?" The answer is simple.
First gather these materials-
- 2 eggs
- Two clear drinking glasses
- Salt
- A tablespoon
Steps-
- Fill two drinking glasses with the same amount of water.
- Next put 8 tablespoons of salt in one of the glasses, not both.
- Put one of the egg in salt water and one egg in fresh water.
- Now one egg floats and one doesn't!
An experiment can be really fun.You get to have fun and know the answers to your science questions.Sometimes you can even make up your own experiments at home if you want to or if you don't have an computer or a science experiment book.You can even do your experiment now if you like
Have Fun!!!!
What does inquiry mean for a science project?
just go to an online dictionary, and you'll find the definition.
What is an example of manipulated variable?
One example:
Janet makes a parachute. She recorded her information on this chart:
Trial #: Descending Time: Weight:
1 5 seconds 7g
2 3 seconds 9g
3 2 seconds 10g
4 9 seconds 3g
The manipulated variable is the weight. A manipulated variable is something you change.
What happens when other scientists achieve different results when repeating an investigation?
They will need to keep redoing it until everyone has the same answer
Why does the vinyl record lift the breakfast cereal right off the table?
Static. Vinyl records lift everything. Just like a rubber balloon rubbed on a kids head.
Is electric car an internal combustion engine or is the a different type of engine?
An electric car is powered by a large electric motor. This motor is powered by the use of magnets in a coil inside the motor. When electric current is run through the motor, the drive shaft spins. This type of motor has an advantage over internal combustion engines because it offers all its torque at 0 rpm, thousands less than internal combustion engines. This makes the car quicker to start and accelerate.
A simple Grade 7 Science Fair Project that is GOOD?
Well the easiest thing you can do is to
- Briantstorm a list of ideas that interest you...
- Choose your top 3 favorite
- ask yourself "what can i measure about this topic" for each question
- Ask your self "how would i measure these things about my topic" for each
- Remember your project should
- Test only 1 variable
- Clearly measurable
- Not use potentionally harmful chemicals, materials, or animals
Hope this helps! ~ Angy
What objects reflect lots of light?
Objects that reflect lots of light include mirrors, polished metal surfaces, glass, and water. These surfaces have smooth and even textures that allow light to bounce off them easily, creating a bright and reflective appearance.
What is a controlled variable in a science fair project?
It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.
Does saltwater prove to retain heat the best or freshwater?
Answer: Pure water has the best capacity for heat of any material known to man, so any impurity must reduce its ability.
Give an advantage and a disadvantage of using online or virtual microscopes?
Advantages of virtual microscopes include the fact that they're a great learning tool, and they require no maintenance. Disadvantages include the fact that the samples are not able to be rescanned, and the ability to manipulate images is limited.
How do you perform planaria regeneration experiment?
Usually a planaria regeneration experiment involves cutting the planaria into different parts. The head can be separated from the tail or the planaria can be cut lengthwise, etc. After cutting the planaria, it will be observed for few days noting how the organism regenerate its lost body parts. Read more on planaria regeneration on t he link provided below.
Why is it bad to use fossil fuels and biomass?
It is bad to use fossil fuels for many reasons:
1) They release CO2 which cause global warming.
2)They won't last forever.
3) Global warming can make some animals extinct.
What are some great 4th grade science fair projects that aredue tomorrow?
Well I'm guessing I'm to late, but baking soda volcanoes are great or you could go to youtube and look up home made science fair projects.
What are the advantages and disadvantages of petroleum for your planet?
Well, for my planet (Zenus 117), petroleum is a major food source, so....
If I exersize it will increase/decrease my breathing rate because....(why you think it will increase or decrease your breathing rate)
What conclusions can be drawn based upon too few facts or observations?
Faulty conclusions may be drawn when they're based upon too few facts or observations. In science, a conclusion is arrived at after a careful search for available, reliable information. That information is dependable when it's based on the careful trial and error recording of experiments, interviews and observations.
