Ensure that measurements are taken carefully and consistently, minimize sources of error by controlling variables, use appropriate equipment calibrated regularly, and take multiple trials to calculate an average for more accurate results.
A plastic soda bottle is a good choice for an air pressure experiment with hardboiled eggs. It is durable, clear for observation, and easy to manipulate for creating changes in air pressure within the bottle. Make sure to use a bottle with a cap that can be sealed tightly to control the air pressure effectively.
Depending on the size/importance of the experiment, they can either simply repeat as normal or if needed gather more resources for the experiments. Scientists always perform experiments at least three times, to make sure nothing is abnormal in an experiment.
Without the data or the requirements nothing can be done
To measure mass accurately in a scientific experiment, you can use a balance or a scale. Place the object you want to measure on the balance or scale and wait for it to stabilize. Record the reading displayed on the balance or scale as the mass of the object. Make sure to calibrate the balance or scale before taking measurements for accuracy.
To ensure the accuracy of experiment results, one must carefully design the experiment, control for variables, replicate the experiment, use appropriate measurement tools, and analyze the data correctly. It is also important to consider sources of bias or errors and eliminate them as much as possible. Peer review and verification by other scientists can further validate the accuracy of the results.
firstly, you have to make sure the only variables are the ones you are monitoring. secondly, you could make sure that the equipment you are using are precise. thirdly, you could try repeating your experiment, and/or comparing results with others, to make sure your results are valid, and you could try omitting anomalous results
Repeat the experiment and make sure it is fair.
When baking a cake, make sure you have the precise amount of ingredients.
that you'll have to do the experiment twice to make completely sure is right
That's highly dependent on the experiment, and there are right and wrong answers for such a vague question. Keep your answer in the right zone and hope for the best.
make sure everything is the same
Precise: Meridith was very PRECISE with her measuring: she'd make sure the sugar was EXACTLY a cup, no more and no less.
To make an experiment more accurate you would have to repeat the experiment 3-5 more times to make it reliable and also you would do what Liverpool college do and compare the answers with other people in the class, community or teacher.
make sure everything is the same
to make sure its correct
I wasn't there
An experiment which can be repeated and will yield the same results. Ex. If x+y=z in the experiement if you try the experiment again you should get the same result "z".
