Photosynthesis

Students use the display to recall the word and symbol equations for photosynthesis and to name what goes into a leaf and what comes out of it.

Students will be able to:

• State the word equation for photosynthesis
• Name the two raw materials, the energy source and the two products
• Explain where in a plant cell photosynthesis happens and why leaves are green

Black and white prints as clean line art rather than a greyed-out copy of the colour version, so the class can colour it in. The preview above changes with this setting.

Paper

• White: 17 sheets — Everything in the print pack
• Green: 5 sheets — Title letters and card backing
• Yellow: 2 sheets — Behind the sun

What is in the pack

• Title letters — PHOTOSYNTHESIS — 4 sheets, black and white

  P · H · O · T · O · S · and 8 more

• Leaf, sun and arrows — 3 sheets, colour

  Leaf with veins, tiled across two sheets · Sun · Four labelled arrows

• Equation strips — 2 sheets, black and white

  carbon dioxide + water + light energy → glucose + oxygen · 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂

  Each equation tiles across two sheets so the text stays large.

• Input and output labels — 1 sheet, black and white

  carbon dioxide (CO₂) · water (H₂O) · light energy · glucose · oxygen (O₂) · chlorophyll

• Fact cards — 2 sheets, colour

  Photosynthesis happens in the chloroplasts, which is where chlorophyll is. · Chlorophyll reflects green light, which is why leaves look green. · Water arrives from the roots through the xylem. · Carbon dioxide enters through tiny holes on the underside of the leaf called stomata. · Glucose is used for respiration, stored as starch, or built into cellulose. · Oxygen leaves through the same stomata that let carbon dioxide in. · and 2 more

• Leaf border strip — 1 sheet, colour

  Repeating leaf-and-vein strip

• Question of the week cards — 1 sheet, black and white

  Why does a plant kept in a dark cupboard turn pale? · Where exactly does the carbon in a tree trunk come from? · A leaf is covered in petroleum jelly on its underside. What happens, and why? · Two plants, same light, one in a sealed jar. Which grows more, and why?

Change the title and the printable letters regenerate to match it.

1. 1

   Step 1 — Prepare the background

   Cover the board in pale blue or white backing paper. A pale background keeps the green leaf readable from a distance.

2. 2

   Step 2 — Add the title

   Cut out PHOTOSYNTHESIS and run it across the top. Fourteen letters is a long title — check it fits before you staple the first one.

3. 3

   Step 3 — Fix the leaf in the centre

   Tape the two leaf sheets together at the back and centre the leaf, leaving room either side for the arrows.

4. 4

   Step 4 — Add the sun and the light arrow

   Put the sun above and to the left of the leaf and run the light-energy arrow down towards it.

5. 5

   Step 5 — Add the inputs and outputs

   Carbon dioxide and water arrows point into the leaf from the left. Oxygen and glucose arrows point out to the right. Keep all four arrows the same length.

6. 6

   Step 6 — Lay the equation strip

   Tape the word equation across the bottom, and the symbol equation directly beneath it, aligned at the arrow.

7. 7

   Step 7 — Finish the border

   Run the leaf border around the outside and pin the fact cards down one side.
