Lesson Topics
What lesson topics are available with Science in a Tree?
Science in a Tree features lesson topics & science experiments that can
only be fully explored in the great outdoors. Each lesson integrates a range of
activities including elements of physics, chemistry, biology, and mathematics.
The science experiments are done under the direction of our education
specialist,
Dean Eckhoff,
who is a PhD physicist with 12 years of classroom teaching experience. We're
happy to work directly with the teachers to customize the program to further
enhance your core curriculum & learning objectives.
We are excited to announce that a greatly expanded series of science
lessons are now available. The lessons are broken up into four general
subject areas:
 Falling Objects
 Photosynthesis
 Simple Machines
 Seed Dispersal
Within each area, there are two different levels of lessons that cover a wide
range of student backgrounds and learning styles. Each of the eight lessons is
described below including pictures taken at previous events. More detailed
lesson plans are available upon request.
FALLING OBJECTS  Race to the Ground!
Gravity & Air Resistance [Gr. 38]
 Drop objects from high in the tree in a series of headtohead races
 Study how the object's properties affect the amount of air resistance
 Develop a simple method to accurately predict the winners & losers
Drag Forces & Terminal Speed [Gr. 712]
 Drop objects from a series of heights and measure their flight times
 Learn about acceleration, terminal speed, and balancing forces
 Show graphically that the objects reach a constant speed as they fall


PHOTOSYNTHESIS  Capture the Sun!
Ground Survey of Campus Trees [Gr. 38]
 Measure the height & circumference of various trees around campus
 Learn about photosynthesis, carbon sequestration, and tree growth
 Model the data to calculate the amount of carbon stored in the trees
Tree Dimensions & Volumetric Modeling [Gr. 712]
 Measure the dimensions of the tree you're climbing in glorious detail
 Model the tree as a series of cones & cylinders to calculate its volume
 Use a spreadsheet to determine the tree's weight & carbon content


SIMPLE MACHINES  Use the Force!
Pendulums & Oscillations [Gr. 38]
 Be part of a giant pendulum as you swing sidetoside in the tree
 Study the effects of mass, length, and amplitude on pendulum motion
 Measure the oscillation time as a function of rope length / height
Pulleys & Mechanical Advantage [Gr. 510]
 Create pulley systems to multiply your strength by 4 times or more
 Measure the force and find out how it relates to distance
 You are the laboratory weight  lift your teacher off the ground


SEED DISPERSAL  Ride the Wind!
Origami Models of Flying Seeds [Gr. 38]
 Create models of dandelion & maple seeds (parachutes & helicopters)
 Drop them from the tree, measure flight time & average speed
 Study seed dispersal mechanisms using common examples of seeds
Dropping Real Seeds: Flyers vs. Rollers [Gr. 510]
 Drop real seeds from the tree and see how far they fly and/or roll
 Learn about properties of seeds that affect how far they are spread
 Measure flight time and distance to quantify the dispersal mechanisms
