Submitted: December 12, 2005
Grade
Levels: PreK,K,1,2,3,4,5,6,7,8.
Essential questions:
Do leaves effect how we feel? What do leaves tell us? What ways
can we sort all the common leaves? How do leaves change color? Do
leaves tell the birds or squirrels anything? What is happening when
they fall off the trees? What is the same about leaves? What is
different? What does their shape tell us? What do we learn from
the leaves?
Goal: Students
will be able to sort leaves as either Palmate, Pinnate, Parallel
or Singles.
Objectives:
Students will be able to recognize the difference between the four
types of common leaf shapes. They will gain an understanding of
the order of nature and changes in form of matter.. They will demonstrate
using technology and working in collaboration to compare size similarities
and differences. They will see how nature inspires humans to create
works of art and build careers.
Aim: is to recognize the four shapes of common leaves.
Activities:
for Pre K, K,1,2,3,4,5,6,7,8 and Special Ed
1. Teacher can have students sit in a circle. Discuss how things
change over time and use the appropriate Essential questions to
motivate students. Teacher could read a book, poem or song to spark
interest and awareness of the importance of leaves.
2. The teacher
will hold up one type of leaf and pass it around. A magnifying glass
can be used. (Social Skills) Each student will take a turn observing
and then pass to their neighbor. After all four types are passes
around, the teacher will give a stacks of worksheets. *Instruction
could be differentiated if student can’t write their own name.
Their names could be pre-printed on them and put in proper order
or they could handed out by teacher calling their name.
3. The teacher
holds up and identifies the shape and students have to tell what
shape it is or point to it on the worksheet. Teacher assesses as
lesson progresses.
4. The teacher
shares the name given to each shape and discusses the special properties.
The teacher does this with all the shapes. Upper grades will do
more of an inquiry of how the leaf falls off and why the singles
stay on all year round.
Pinnate (Oak)is skinny like a feather with lobes. Palmate(Maple)
is fat like a palm spread open with lobes. Parallel (Cherry Blossom)
is rounded with no lobes and the veins are symmetrical or parallel
to each other. Singles(Hemp) are one single vein. Like a needle.
*Upper grades can go discover chloroplasts in the leaf which from
the Sun’s electromagnetic radiation convert carbon dioxide
from the atmosphere and water into carbohydrates as glucose. Glucose
is an energy rich sugar which all cellulose and polymers are made.
Energy +CO2 + H20 change to carbohydrate + 02) Hence why the leaves
change colors when the sap stops and the spore drys. Singles spores
keep producing sap.
5. The students are asked to chose one shape and reproduce the leaf
on drawing paper and label the shape. An Inquiry can be done why
the shape was chosen. Upper grades can create a song, poem or simple
write how they would feel if they were that shape of leaf in autumn.
Lower grades can dance to music pretending they are a leaf about
to fall. .
6. Capable students
can do a web quest to find a poem, song or painting which has the
subjects of leaves and then come back and share with the group.
: .
Strategies: questioning, creating and using cooperative learning,
wait time-think-time, and active-listening.
Materials: Specimens of the four types of common leaves. Drawing
paper, crayons, pencils, markers, worksheets, magnifying glass,
ruler, Lists of other activities, website, book lists, songs and
poems.
Assessments:
: Quiz, class participation, work samples, group work, web quest
results,and oral presentation. ( See rubric).
