Science activities and experiments for Std 6 to 8
When a hypothesis is supported, refuted, or proved, an experiment is conducted। Experiments give information on cause and effect by showing what happens when a particular factor is changed। Objectives and scope of experiments vary greatly, but they are always based on a repeatable process and logical analysis of the results।

Std 6 to 8 Science activities and experiments
There are also natural experiments। A child may do simple experiments to learn about gravity, but teams of scientists may need years of systematic investigation to understand a phenomenon।

Experiments and other hands-on activities are critical to student learning in science classrooms। Experiments, especially when done over time, have the potential to improve test scores and help a student become more interested and engaged in what they are learning।
Experiments can vary from informal and personal natural comparisons to highly controlled (for example, tasting a variety of chocolates to find a favorite one) to complex apparatus required (for example, tests conducted by many scientists hoping to find information about subatomic particles)। Experiments are used in different ways in the natural and human sciences।

controls are usually included in experiments to minimize the impact of other variables than the single independent variable। This makes the results more reliable by comparing the control measurements with the other measurements। Scientific method includes scientific controls।
Ideally, every variable in an experiment is controlled (by the control measures) and none is uncontrolled। If all the controls in such an experiment work as expected, it is possible to conclude that the experiment works as expected and that the results are due to the variable that was tested। An experiment is an empirical procedure that arbitrates competing models or hypotheses in the scientific method। Also, researchers use experimentation to verify or disprove new hypotheses or established theories।

An experiment generally tests a hypothesis, which is an expectation about how a particular process or phenomenon works. However, an experiment may also aim to answer a “what if” question, without a specific expectation about what the experiment reveals, or to confirm previous results. If an experiment is done carefully, the results generally support or disprove the hypothesis.
According to some philosophies of science, an experiment can never “test” a hypothesis, it can only add support. On the other hand, an experiment that provides a counterexample may disprove a theory or hypothesis, but a theory can always be salvaged by appropriate ad hoc modifications at the expense of simplicity. An experiment must also control for potential confounders – any factor that could spoil the precision or repeatability of the experiment or the ability to interpret the results. Confusion is commonly removed by scientific controls and / or, in randomized experiments, by random assignment.
In engineering and physical sciences, experiments are a major component of the scientific method. They are used to test theories and hypotheses about how physical processes work under particular conditions (for example, whether a particular engineering process can produce a desired chemical compound). Typically, experiments in these fields focus on replicating identical procedures in the hope of producing identical results at each replication. Random assignment is rare.

In medicine and the social sciences, the prevalence of experimental research varies widely between disciplines. However, when used, experiments usually follow the form of the clinical trial, where experimental units (usually individual humans) are randomly assigned to a treatment or control condition where one or more outcomes are evaluated.
In contrast to the norms of the physical sciences, the focus is usually on the average treatment effect (the difference in results between the treatment and control groups) or other test statistic produced by the experiment. Usually a single study does not involve replicates of the experiment, but separate studies can be added through a systematic review and meta-analysis.
There are several differences in experimental practice in each of the branches of science. For example, agricultural research often uses randomized experiments (for example, to test the comparative effectiveness of different fertilizers), while experimental economics often involves experimental testing of theorized human behaviors without relying on the random assignment of individuals to conditions. treatment and control.
