Science Experiment
The article presents an educational activity for grades 4 to 6 which will lead students through a purposely flawed investigation of popcorn. According to the author, the activity will allow the students to determine the potential sources of experimental error and describe ways to minimize these errors in an experiment which include measurement error, design error, and sampling error. The article also cites an experiment made by a fourth-grader named Becky with seed germination for the science fair to know how two types of light affect germination in peas.

    Background and Aims In arid environments many plant species are found associated with the canopies of woody perennials. Favourable conditions for establishment under canopies are likely to be associated with shade, but under canopies shade is distributed patchily and differs in quality. Diurnal...

    Error is protean, ubiquitous and crucial in scientific process. In this paper it is argued that understanding scientific process requires what is currently absent: an adaptable, context-sensitive functional role for error in science that naturally harnesses error identification and avoidance to...

    Students observe a tree bud from late winter until it sprouts. They learn to use dichotomous keys to identify their tree. The activity is inquiry-based; students predict when their bud will open and what it will become. Student drawings, quotes, and data are included to exemplify the process....

    : Background and Aims The chemical composition of green coffee and thus the final coffee quality are specifically determined by the mode of post-harvest treatment, i.e. the wet and dry processing. Recently, it was shown that metabolic processes, i.e. germination and, a slightly delayed...

    Background and Aims There is considerable confusion in the literature concerning impermeability of seeds with ‘hard’ seed coats, because the ability to take up (imbibe) water has not been tested in most of them. Seeds of Opuntia tomentosa were reported recently to have a...

    The aim of the present study was to evaluate the effect of 19 Rhizobium strains on seed germination and growth of Lycopersicon esculentum plants. The effect of Rhizobium on germination was determined by inoculating the seeds with dense suspensions of Rhizobium and germinating them in sterilized...
