Assessment ISA (PU 2.5) Light Dependent Resistors (Section 1) 1. Write down your hypothesis. Explain why you made this hypothesis. Hypothesis: When it is day there is more light hitting the LDR and so its resistance decreases and the light turns off. When it is night there is less light so the LDR has higher resistance and the light turns on. Explanation: When light shines on a Light Dependent Resistor‚ electrons are released and the current can get larger. So as the light intensity increases‚ more

The Compound Light Microscope Commonly binocular (two eyepieces)‚ the compound light microscope‚ combines the power of lenses and light to enlarge the subject being viewed. Typically‚ the eyepiece itself allows for 10X or 15X magnification and when combined with the three or four objective lenses‚ which can be rotated into the field of view‚ produce higher magnification to a maximum of around 1000X generally. The compound light microscope is popular among botanists for studying plant cells‚ in

LIGHT EMITTING DIODES Light Emitting Diodes are electronic components that use the flow of electrons to excite materials into emitting photons of light. A diode is a basic electronic component that allows electricity to flow one way only. The discovery of "light emitting" diodes we believe was an accident sometime around 1907 when a diode in an early radio transmitter was noticed to glow when in use. Incandescent bulbs use resistance in a filament to impede the flow of electricity‚ heating

Ryan Getherall November 3‚ 2014 Light/Dark Paragraphs In the novel‚ A Tale of Two Cities‚ by Charles Dickens‚ the author uses light and dark to set the tone. The tone of this novel is mysterious‚ dark‚ and depressing. At the beginning of the novel‚ Dickens says “It was the season of Light‚ it was the season of Darkness‚ it was the spring of hope‚ it was the winter of despair” (7). In this quote‚ Dickens uses paradox to explain the controversy between the light and darkness throughout. When

Rage against the Dying of the Light Death is one thing in life that can’t be avoided. It might be avoided temporarily or pray on constantly‚ but death is the way of life. In the poem "Do not go gentle into that good night." Dylan Thomas explores the weakness related to growing old and leaning toward death. The six stanzas in this poem show reveals the Thomas complicated meaning towards death. Thomas wrote this poem during the last illness of his father‚ which influences and expresses his strong

This story “Araby”‚ written by James Joyce‚ is seen showing readers variations of light. The beginning discusses childhood summer passing‚ as winter becoming current setting. It contains sentences with notion of darkness‚ such as “The space of sky above us was the colour of ever-changing violet”(p.107) and ”towards it the lamps of the street lifted their feeble lanterns”(p.107). With this setting we can anticipate that there’s something in the street of dark energy from lifting lanterns. Skies‚ also

Photosynthesis Essay During the Light Dependent Reactions‚ activity occurs within the thylakoids of the chloroplast. NADP+ accepts two high energy electrons and an H+ ion and then converts into NADPH. This process ultimately traps some of the sunlight in chemical form. Then‚ NADPH is able to carry the energy it absorbs to the rest of the cell. The reaction produces O2 gas and converts ADP to ATP and NADP+ to NADPH. First‚ pigments in Photosystem II absorb light‚ which is then absorbed by electrons
