 - Lesson 02 - How do organisms get energy? Lesson Plan Lesson Title
 - Plants making carbohydrates in their leaves by photosynthesis - KS3.B.15

 - Green plants get their energy from the sun through photosynthesis. (FROM 2B) - KS3.B.30
 - 'Photo' is from the Greek for 'light'. - KS3.B.30
 - 'Synthesis' is from the Greek for 'put together or combine'. - KS3.B.30
 - Suggested Activity:
 Synthesis spelling can be remembered by having a sister called cynthia:
 
 syn - the - sis
 - Synthesis is the bonding together of small particles to form bigger particles. - KS3.B.30
 - Decomposition is the splitting of large particles in smaller particles. - KS3.B.30
 - T: Most photosynthesis takes place in palisade cells. - KS3.B.02
 - W: Palisade cells are adapted for photosynthesis by having lots of chloroplasts.
 
 NB: Main thrust of lessons should be looking at cells. - KS3.B.02
 - D: Cover leaves to later test for starch.
 - Lesson 03 - What does the word equation for photosynthesis mean? Lesson Plan Lesson Title
 - T: The word summary for photosynthesis is:
 
 Carbon Dioxide plus Water becomes Glucose plus Oxygen using light energy. - KS3.B.23
 - W: The reactants of photosynthesis are:
 Carbon Dioxide and Water - KS3.B.23
 - W: Carbon Dioxide is absorbed from the air. - KS3.B.23
 - W: Water is absorbed from the ground through the roots. - KS3.B.23
 - T: Carbon dioxide is absorbed through the leaves. - KS3.B.23
 - W: The products of photosynthesis are:
 Glucose and Oxygen - KS3.B.23
 - W: Glucose is used or stored in the plant. - KS3.B.23
 - W: Oxygen is released through the leaves into the air. - KS3.B.23
 - T: Glucose is converted into starch for storage. - KS3.B.23
 - T: The word summary for respiration is:
 
 Glucose plus Oxygen becomes Carbon Dioxide plus Water releasing energy. - KS3.B.23
 - Lesson 04 - What does the symbol equation for photosynthesis mean? Lesson Plan Lesson Title
 - T: The symbol equation for photosynthesis is:
 
 CO2 plus H2O -> C6H12O6
 
 With a wavy arrow showing the light energy. - KS3.B.23
 - Suggested Activity:
 The wavy arrow distinguishes between the Big Ideas of Particles and Energy.
 - A: Students can identify the number of elements in a compound from its formulae. -
 
 Students can identify the number of atoms in a compound from its formulae - KS3.C.05
 - Suggested Activity:
 For each chemical in photosynthesis eg:
 
 Carbon dioxide is made up of the elements of Carbon and Oxygen.
 
 The molecule consists of three atoms.
 - A: Chemical reactions result from the rearrangement of atoms. - KS3.C.12
 - Suggested Activity:
 Use the chant and Particles -
 Chemical writing frame to explain what is happening:
 
 - Molecules (Hands make fists)
 - Collide (Bag fists together twice, sticking together the second time)
 - Split (Spread fingers out)
 - Rearrange (Slide hands one in front of the other, then the other way round
 - Bond (interlock fingers)
 - Become a new substance (roll hands to 'present' new substance)
 - A: DESIRABLE:
 No particles are created or destroyed in a chemical reaction.
 
 Therefore the equation needs to be balanced. - KS3.C.06
 - A: Photosynthesis is an endothermic chemical reactions because it takes energy to build bigger molecules. - KS3.C.21
 - Suggested Activity:
 Energy ENters in ENdothermic reactions
 - T: The symbol equation for respiration is:
 
 C6H12O6 -> CO2 plus H2O
 
 With a wavy arrow showing the energy leaving the reaction. - KS3.B.23
 - A: Respiration is an exothermic chemical reactions because it releases energy when bigger molecules are split. - KS3.C.21
 - Suggested Activity:
 Energy EXits in EXothermic reactions
 - D: Measure cress seedlings
 - Lesson 05 - How are leaves adapted for photosynthesis? Lesson Plan Lesson Title
 - Leaves are flat and so have a large surface area to collect the sunlight. - KS3.B.25
 - Suggested Activity:
 observe stomata using slides of cells and microscopes
 Equipment Required:
 Nail varnish, leaves, slides, microscopes, prepared slides of cells, sellotape
 - The palisade cells, found towards the top of the leaves, have lots of chloroplast which perform photosynthesis. - KS3.B.25
 - D: Measure cress seedlings
 - Lesson 06 - How can we prove that light is needed for photosynthesis Lesson Plan Lesson Title
 - A: Glucose is converted into starch for storage. - KS3.B.23
 - The test for starch is it reacts with iodine, turning black.
 - D: Test half covered leaves for starch.
 - EW: Write a conclusion and then explain it using big ideas
 - Suggested Activity:
 Extended Writing (TOWER)
 
 T - Talk in groups
 O - Organise visually (Flow map)
