Lab Design “Investigate the effect of a factor on the number of stomata of a leaf.” Research Question: How do differing leaf heights affect the number/density of stomata of a leaf? Hypothesis Stomata are pores‚ typically found under the leaf (lower epidermis)‚ that control the gas exchange of transpiration‚ where water vapor leaves the plants‚ and carbon dioxide enters. I predict that the stomatal density on high leafs is higher than on low leafs. During photosynthesis the chloroplasts

Mechanical Waves Background Mechanical waves are waves which require a medium for propagation since energy is transferred via the motion of the medium. An example of a mechanical wave is sound. Transverse waves are waves which vibrate perpendicular to their direction of propagation. Surface water waves can be classified as a transverse wave. All electromagnetic waves are also examples of transverse waves. A longitudinal wave is a wave in which its particles vibrate parallel to their direction of

Investigating the resistance of a wire. Planning For this investigation there are a number of variables that can be chosen to change or keep the same‚ these are: · Length of the wire. · Diameter of the wire. · Type of the wire. · Temperature of the wire. Scientific explanation. All electrical conductors resist current through them to some extent. This is resistance and this affects the size of the current flow. The main dependence of resistance are: § It’s Length. § It’s Thickness

Waves effect our everyday life in many ways. Waves are very interesting ways to travel‚ and we don’t mean surfing! Many things we use every day involve waves.

During each wave of immigration into the United States‚ immigrants have faced many different injustices. Each successive wave of immigrants‚ however‚ discovered a better America. Immigrants in the second (Pre-Civil War) and the third wave (1880-1920) faced an America that focused on “Americanizing” them. This desire to strip immigrants of their culture did not exist on the same level after World War II and so the fourth wave of immigrants discovered an America more likely to accept them and their
