Use easily obtainable materials for your classroom science experiments. If you plan experiments that involve scarce resources or hard-to-obtain equipment and supplies, your experiments will become troublesome and you might lose your motivation to conduct the experiments. Plan your experiments to include supplies that you can find with little effort and give yourself the opportunity to enjoy doing the experiments as much as the students enjoy the procedure.
Conduct science experiments with clear and easy directions. Ensure that you understand the directions before you conduct the experiment in your classroom. Do a dry run of the experiment at home before you do it for your class. The principles and concepts that your experiment demonstrates will have the desired effect if you check all procedures before you do the project in the classroom.
Provide the students with activities that prepare them for the science experiment before you conduct the experiment and other activities that sum up the experiment at its finish. A successful lesson plan includes an introduction, a middle and a concluding activity. The actual experiment should sandwich in between a preceding activity that introduces the experiment and a concluding activity.
Prepare for a mess. Some of the most successful science experiments involve explosions and lots of mess. Assign the students clean-up tasks before you begin the experiment to reduce the stress of cleaning up afterward. If the experiment involves loud noises, tell the students what to expect so they will know what to expect.
