Preparing for Science Experiments


When preparing to do science experiments, there are some basic rules that you need to follow if you want to get accurate results. Here are some of the things you need to consider when setting up your experiments.


Whether you are working with an absorptive filter or ingredients from the fridge, weighing solid samples is crucial. Even the smallest allowances in weight differences can lead to errors in the experiment. If you’re seeking to prove the absorption filter method or make snow in the kitchen, you must ensure that your samples are weighed properly.

Volumetric Dilutions

Always use top-notch measuring cups when dealing with fluids. These have been checked and can be trusted as accurate. Cheaper measuring cups can introduce errors in your experiment. Similarly, make sure any pipettes you use are also accurate.

Purity of Added Reagents

Always use reagent-grade chemicals to ensure purity and reduce other materials being introduced by mistake. You may also want to use ultra-pure chemicals if your experiment is crucial.

Control of Interferences

Make sure you research your chemicals before beginning your experiment and identify what could interfere with your results. Then, take any necessary precautions to control the possibility of interferences.


Plan out the standards for your experiment ahead of time. Take into consideration how any ingredients can degrade over time. Then, make sure that you follow these standards strictly to ensure accurate results.


Calibrate all of your equipment before you start experimenting. This ensures that your analysis will be accurate and you are following your standards.

Validity of the Blank

Whether you call it a blank or control, you need to make sure that it is actually something neutral. This can tell you whether your experiment is working or failing.


Clean all of your equipment before you start any experiment. This ensures that nothing can interfere with your experiment.


Sometimes experiments require the use of a corrosive solution. If you find yourself in this situation, you need to have a corrosive-resistant nebulizer nearby to prevent contamination.


While experimenting, remember to be as precise as possible. This means following your standard and any instructions you are given as closely as possible. Deviating from this plan can have disastrous consequences that will ruin your experiment.

There are several things you can do to ensure your science experiments go according to plan. Take these precautions if you want the greatest chance of success.
