Some class: "Porky is a pig. He lives on a farm. He loves to roll in the mud. Porky really likes to eat. One day porky heard the farmer was going to kill Porky and all the other pigs, so Porky decided it was time to go on a diet. No more junk food. Fresh fruits and green leafy vegetables were all he ate. By the end of the month Porky was the skinniest pig on the farm. All the other pigs thought that Porky was crazy. They all laughed. Porky said “You won’t be laughing when you get turned to bacon and ham”. The pigs got scared. They decided to go on a diet too. All the pigs got so skinny the farmer decided not to kill them. From now on, all the pigs on the farm ate a heathy diet and did yoga. The End"
So that's what Babe did wrong...
Some class: "3. An important gas that is released during photosynthesis is photosynthesis.
4. The Contrast between photosynthesis and respiration is photosynthesis."
