You can conduct an experiment using different materials (e.g. metal, wood, plastic) exposed to sunlight and measure their temperature increase over time. The material that shows the highest temperature rise is a better absorber of heat. Alternatively, you can use a heat lamp and measure the temperature increase on different surfaces to determine which one absorbs heat more efficiently.
Requirements: 2 thermometers, black paint Procedure: Paint 1 of the thermometers black and do not do anything with the 2nd one. Keep both thermometers in sun for an hour or two. After an hour record the temperature of both thermometers you will find that the one painted black shows more temperature as compared to the second. Conclusion: Dull colours are good absorbers of heat.
A more definitive answer: If you look at a dull surface under a microscope you'll find that is is not smooth, even if it appears so to the naked eye. There are may microscopic bumps and depressions. This means that rather than a single, consistent surface there are many tiny surfaces facing in random directions. Light is subsequently reflected in random directions. In other words, there is no consistent reflection. Conversely, a shiny surface will appear much smoother. The irregularities on such a surface are generally too small to affect light in the visible spectrum. This means there is a single consistent surface for light to reflect from.
The conclusions of a force table experiment typically involve analyzing the equilibrium of forces acting on an object placed on the force table. By adjusting the magnitudes and angles of the forces, one can observe the conditions necessary for equilibrium to be achieved. This experiment allows students to understand the concept of vector addition and how to find the equilibrant force.
To find the coefficient of dynamic friction, conduct an experiment by placing a block on a flat surface connected to a force sensor. Apply a horizontal force gradually to the block until it starts to slide, and note the force required for motion to begin. Use the formula: coefficient of dynamic friction = (force to start motion) / (weight of the block) to calculate the coefficient. Repeat the experiment multiple times to get an average value.
A test performed to find out if a hypothesis is supported is called an experiment. This involves conducting controlled investigations to observe and measure outcomes to determine whether the hypothesis is valid.
Yes. Try them in both.

Make one with each. The baking powder will perform better.
You can find someone else to experiment...
Write an experiment to find the velocity of sound?
It is certainly possible. The conclusion from your experiment may prove to be tentative and you may need to design a better experiment to improve the reliability of the conclusion, or the experiment may suggest alternatives which you may wish to explore. Most of science is about that: an experiment leads to conclusions. Further experiments result in refinements to the conclusions and, occasionally, to the replacement of earlier theories with new models.
a expirimental television is a telivis ion that scientist experiment on to see if they can find any new information about it. since they dont have anything else better to do.
All you do is count the surfaces of it. It's not like your trying to find an actual face. :) If you count the surfaces you are sure to succeed.
Sample size greatly reduces any error to randomness in a given sample. Each experiment requires a proper size of a sample. The better it is fitted to the experiment, the better is the result. For example, if you are trying to find out the study habits of students at your school of 1000 kids, a sample size of 50 would be sufficient. However, if you are trying to find out the study habits of students across the US, a sample size of at least several hundred-thousand would be required, preferably several million.

Select an experiment that has a random result rather than one that is deterministic. The result of the experiment is the outcome of the probabilistic experiment.
Yes, that is possible. It's to be expected.
