Controlled 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

In Sherry Turkle’s essay How Computers Changed the Way We Think‚ she said “we have to ask‚ as educators and citizens‚ whether current technology is leading us in directions that server our human purpose”. She goes on to say that “these questions are not technical; but social‚ moral and political”. In this essay I will discuss these questions and what concerned her the most.

Are People too dependent on Technology? Glenda K. Walker Strayer University Critical Thinking – PHI 210 December 1‚ 2014 Professor Earle J. Fisher Abstract My question is “Are people to dependent on technology?” My answer is most definitely. Have you ever been to a restaurant and no one at the table is talking‚ they are all on their cellular devices. I can assure they are texting‚ checking emails‚ or playing a game. What has happened to the old fashion way of communication? I can tell you

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

Are We Too Dependent on Computers? We have become too dependent on computers for answers‚ personal interactions‚ and we spend way too much time on them. If we used the computers for learning and as a tool this issue wouldn’t be as big. The sad truth is that people use this great tool for an easy way to get out of face to face interactions with other people. In 10-20 years it is said that there will be a computer smarter than the whole human race alive today. That is a scary future that we don’t
