The objective of this article is to evaluate how the use of low-cost experiments affects the learning of the topic Aliphatic hydrocarbons. The methodology responds to a quasi-experimental type of research with a mixed approach, in addition to a control group and an experimental group. The participants are the students of the 3rd year of high school of the Luis Cordero Educational Unit of parallel B and D in the academic period 2022-2023. On the other hand, the instruments used are a survey, a pretest and posttest questionnaire, which allowed to identify the initial and final state of the two sample groups, as well as to determine the impact of the low-cost experiments on learning. To this end, the research was approached in three phases: diagnosis, planning and implementation, and evaluation. The results indicate that the use of low-cost experiments promotes collaborative work and class participation. It also contributes to better grades and active student-teacher interaction.
