Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. The equation for photosynthesis: Carbon Dioxide + Water (+ Light Energy) → Glucose + Oxygen Symbol equation: 6CO2 + 6H2O ------> C6H12O6 + 6O2 (http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/plants/plants1

Chapter 12 section 1 review 1) what characteristics of gases makes them different from liquids or solids? Gases have particles that are have a greater distance apart from each other than the particles between a solids and a liquid 2) why are gasses considered fluids? Gasses are fluids because they are able to flow 3) what’s happens to gas particles when a gas is compressed? When a gas is compressed it will move gas particles closer and make the volume smaller. 4) what is the

October 13‚ 2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden

Chemistry SCH3U-B‚ Unit 2‚ Lesson 6: Key Questions 19. Based on the observations provided in the kitchen lab‚ “Developing an Activity Series”‚ the order of the four metals from most reactive to least reactive is: zinc‚ iron‚ nickel‚ copper. Zinc is the most reactive. The reaction occurred quickly… small bubbles (hydrogen) appeared straight away. As the reaction continued‚ larger bubbles (more hydrogen) appeared. At the end of the experiment‚ the nail was completely rusted. Hydrogen displaced the
