What do you think the key words are for todays lesson?

Lesson Objectives Lesson Competency (Level 1-3) Proficiency Mastery (Level 7-9) 1 Write the word and symbol equation for photosynthesis Explain why photosynthesis is important for the survival of other organisms. Explain why the leaves are tested for starch and not for sugar.

What organ does what? To pump blood To break up food and absorb it To clean blood and make urine To control the body To break up food For protection and feeling To remove water from unwanted food For breathing To make and destroy substances

Plants have organs too! What are the four main organs of a plant?

Organ Function Drawing Stem Leaf Flower Root Use the information cards to fill in the table below; Organ Function Drawing Stem Leaf Flower Root

The stem helps to support the plant. What is the function of the stem? The stem helps to support the plant. stem It also carries water and food around the plant.

What is the function of the leaves? The leaves use sunlight to provide the plant with energy. leaf

What is the function of the flower? The flower helps the plant to reproduce. flower

What is the function of the roots? The roots absorb water, nutrients from the soil. root They also keep the plant in the soil!

Who’s going to photosynthesize more?

What factors affect photosynthesis? Temperature Light Intensity CO2 Concentration

What do all leaves have in common?

Stomata is where the carbon dioxide enters and oxygen exits the leaf

How are leaves adapted for photosynthesis?

What is the function of the root? What is produced in photosynthesis? What is the function of the flower? How do leaves get water? What is the equation for photosynthesis? What are the holes under the leaves called? What is the function of chlorophyll? Why are leaves thin? Why are leaves broad?

Stomata is where the carbon dioxide enters and oxygen exits the leaf

Work in progress The thing I have found most difficult in this lesson so far… So far I have been successful in my learning because… I can now make links to… The most important thing I’ve learned so far… New science key words I have learned… I did not know… but now I know… and I know this because… I feel confident about my progress in this lesson because… Two new facts about what I have learnt so far which I will tell someone are... I have learned several new things about this topic. Firstly… Furthermore… A golden rule that I will remember… A question that I have about today’s lesson so far… One thing I need to remember from the work I have completed so far… So far in this lesson I have tried…
