Model Secondary School for the Deaf SOAR-High2  Earth System Science class Spring Budburst Study Spring 2002 Location: 800 Florida Ave, NE, Washington  Latitude (N,38deg 53' Longitude    W 77deg'

Tree #1  Silver Maple   (Acer saccharinum)
Observers:  Krzys, Ebony, Trey

Our Tree in February! February 22, 2002 We want to know what day the buds will burst!    We want to know what causes budburst on that date.  Maybe it depends on temperature, or precipitation.	Our Tree in April! April 14, 2002 We picked this tree to study.   We wanted to know the name of the tree.  We observe the tree everyday.  We write in our journal every day about the tree. We measured the height of the tree and found out it is 12.0 meters tall.	Our Tree only 4 days later! April 18, 2002
Krzys's branch,  February 22, 2002  We think these are flowers (in February). We learned the flowers have male and female parts. There are no leaves yet.  We think there will be leaves when it becomes warm.	April 14, 2002 We learned the tree's name is Silver Maple (Acer saccharinum)	May 21, 2002
February 22, 2002 Ebony observes the Maple buds. The tiny Maple Flowers cover the branch. We tied a pink marker to the branch so we can find it later.	Ebony's April 8, 2002 The buds appeared swollen on the tree. They don't show budburst yet. The reason for that is it is still cold outside.	Ebony's branch, May 21, 2002
Trey's branch, April 14, 2002	Trey measures new leaves, April 14, 2002	Trey's branch,  April 18, 2002

 

Tree #2 Crab Apple  (Pyrus coronaria)
Observers:  Nicole, Les, Tina

Our Tree in February! February 15, 2002 We wanted to know what day the buds will burst for this tree.  We observed this tree and made a drawing to show what the buds look like.   Later the buds will grow and become leaves and white flowers.	Our Tree in April! April 8, 2002 We learned this is a Crab Apple tree. ( Scientific Name: Pyrus coronaria) We measured the height of the tree.  It is 5.3 meters high	Our Tree a week later! April 18, 2002
Les's branch, February 15, 2002 This picture shows early swollen buds waiting to burst. It is still cold outside.	Les's branch, February 28, 2002	Les,  April 18, 2002
Tina's Branch, February  28, 2002 This picture shows swollen buds.	Tina's Branch, April 8, 2002 The buds have burst. Both flowers and leaves are growing.	May 21, 2002
Nicole's branch,   March 1, 2002 This picture shows leaves growing!  The buds burst on March 2.	Nicole's branch, April 8, 2002 The leaves are 3.0 cm long on April 8, 2002.	Nicole's branch, April 18, 2002

Temperature and Precipitation Record

The GLOBE  Weather Station

The weather station helps us measure air temperature and precipitation. The station is very important to us because it helps us find out how temperature and precipitation influence budburst.
