This fun science activity for kids will teach students how deciduous trees change across the seasons. Students will then have the opportunity to track and record how an individual tree changes over the period of a year. In this activity learners will be shown how a deciduous tree changes across the seasons, then either as a class or individually recording how an individual tree changes over the school year. This activity is inspired by Greek mythology. A dryad is a mythical Greek creature, often associated with forests. They are said to be female nymphs who inhabit trees or woods and protect them from harm. Dryads have been featured in many stories throughout history, and they often symbolize the beauty and power of nature. This activity could be introduced as part of a main lesson activity at the start of the new year. It could then be followed up on a weekly (or periodic) basis over the year, with learners building up a record of how the identified tree within the school grounds changes over time. This could be used either to create a diary, a logbook, or it could form the basis for a classroom display. This is a long-term activity which can run for the duration of the school year. Following an initial introduction, individual learners or table groupings could be responsible for completing the diary on a weekly basis. If carried out by individuals, different learners could be allocated the responsibility each week, progressing through the class register. An appropriate tree within the school grounds needs to be identified. Ideally a tree visible from the classroom would be used. As applicable by local requirements, risk assessments may need to be carried out if the learners need to go outside the school building to carry out this activity. For continuity it is advantageous to have a set position from which the picture or observations are made. Tools/resources required Projector Copies of the How do deciduous trees change handout Digital cameras (if required) with access to suitable printing facilities The engineering context Environmental engineers are tasked with improving the quality of the natural environment around them. The more they understand about this, the better they can do their jobs. Suggested learning outcomes By the end of this activity students will be able to describe how a deciduous tree changes with the seasons. All activity sheets and supporting resources are free to download, and all the documents are fully editable, so you can tailor them to your students’ and your schools’ needs.
