Introduction: Trying to find a good‚ quantitative procedure that students can use for exploring photosynthesis is a challenge. The standard procedures such as counting oxygen bubbles generated by an elodea stem tend to not be “student” proof or reliable. This is a particular problem if your laboratory instruction emphasizes student-generated questions. Over the years‚ I have found the floating leaf disk assay technique to be reliable and understandable to students. Once the students are familiar

It has recently been found that material hardship impacts the development of a child. Specifically‚ authors Huang and Sherraden (2016) found that material hardship has a negative association with the social-emotional development of young children. Although it is generally known that different aspects impact the physical and emotional development of children‚ it is unclear as to which have a direct effect on a child’s brain development. To be successful in life‚ the development of all areas in the

Aim To work out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is‚ the more photosynthesis‚ the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because

PSY 225 Research Methods Spring 2013 Review Sheet Exam 1 CHAPTER 1 Why is the methods course believed to provide a “foundation” for other psychology courses? Hint: process vs. content. A methods course teaches a process (of doing research) that applies to other content courses. How do research psychologists use the terms determinism and objectivity? +Determinism= the idea that events‚ including psychological ones‚ have causes statistical determinism= events can be predicted‚ but only

Segregation is caused by * Too wet mix‚ extremely high workability or less cohesive mixture causes the mixture unable to hold heavy aggregate * Dropping from excessive height * Over compaction of fresh concrete. Two methods to minimize segregation in fresh concrete: * Adequate workability is enough. * Don’t over

GLIGORIJEVIĆ Jeremija JEVTIĆ Djuro BORAK Abstract. Materials and process selection are key issues in optimal design of industrial products. Substituting and selecting materials for different machining parts is relatively common and often. Material selection is a difficult and subtle task‚ due to the immense number of different available materials. From this point of view paper deal with a set of major gear design criteria which are used for gear material selection. The main gear design criteria are:

ESL Methods - English Language Teaching The field of linguistics and teaching in the 20th century is marked by the development of different foreign language teaching methods and approaches. Some have no or small following and others are widely used Although modern foreign language teaching has adopted completely new methods‚ the work of language professionals in the period between 1950 and 1980 contributed significantly to scientific views in the field of second language teaching and learning.
