A2: The Garden Problem Grade 6

Background: School Garden A school was built on an old lettuce farm. Plants do not grow in the school garden. Why? Did the old farm use up everything in the soil? Garden observations were made for 1 week. Noon temperature averaged 21 C = 70 F. Every day was sunny. Soil was dry and sandy. On other side of school is a watered yard with healthy green plants and different color soil.

Background: Plant Needs Almost every plant needs four things to grow: Air Sunlight Water Soil If even one is missing, the plant won’t be able to survive because it can’t make food for itself

Vocabulary Celsius: Data: Evidence: Opinion: Metric temperature scale Facts about something used for planning Evidence: Proof, facts or knowledge from observation Opinion: Strong belief but no exact support or knowledge
