Seventh Grade Talking Points
- "Did you know that the tradition of using evergreen trees as Christmas trees dates back to ancient times? People believed that evergreen trees symbolized life and rebirth because they stayed green throughout the year, even during the cold winter months."
- "Mistletoe is a fascinating plant that grows on the branches of other trees. It doesn't have roots in the ground like most plants, but instead, it obtains water and nutrients from its host tree. This unique adaptation allows mistletoe to survive in various environments."
- "Poinsettias are known for their vibrant red leaves, which are actually modified leaves called bracts. The flowers of poinsettias are small and yellow. It's interesting to note that poinsettias are native to Mexico, where they are associated with Christmas celebrations."
