Do Plants Eat?
Learners explain that photosynthesis is a process that plants use to convert light energy into glucose. They summarize photosynthesis as a chemical process in which the plant uses carbon dioxide and water to form glucose and oxygen.

Move Your Muscles!
Students, through teacher lecture and class discussion, explore the three different types of muscles in the human body and the effects of microgravity on these muscles. They explain what happens to muscles in outer space and describe the...

Kepler's 3rd Law
Students derive the velocity in a circular orbit of any radius. They derive the Earth escape velocity and prove Kepler's 3rd law for circular orbits # A simple formula for the orbital period in a circular Earth orbit of given radius.

What a Drag!
Stop and drop what is in your hand! Pupils investigate how form effects drag in the 12th part of a 22-part unit on aviation. Groups create equally weighted objects and determine which one falls the fastest by collecting data.

Fun with Bernoulli
Reduce the pressure in the classroom. The second instructional activity in an Airplanes unit of 22 introduces the class to Bernoulli's Principle. Pupils demonstrate the principle by blowing between different objects causing a reduction...

Light Intensity Lab
Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.
Curated OER
Density
Students, in groups, design a procedure to calculate the mass of gas molecules in the classroom by measuring the volume of the classroom and researching the density of air. They apply changes in air density with altitude and effects on a...
Curated OER
An Arm and A Leg
Students examine how the movements of bones are dependent on the interaction of pairs of muscles. They design and construct a prototype of an artificial limb using a syringe system, and determine whether water or air makes the appendage...
Curated OER
Aruba Cloud Cover Measured by Satellite
Students analyze cloud cover over Aruba. They compose and submit written conclusions which include data, analysis, errors in data collection, and references.
Curated OER
Cloud Observation and Graphing
Students identify the three major cloud groups. They are introduced to the three main cloud types and spend a week making and recording observations of clouds. Students produce a graph that presents their findings and conduct research...
Curated OER
Cloud Shadows
Students classify clouds as transparent, translucent or opaque. They conduct an experiment to determine the visual opacity of several classroom objects and then conduct further observations of clouds.
Curated OER
Environment: Battling for Oxygen
Students construct an interactive ozone depletion model using gumdrops and toothpicks. After analyzing the data obtained from the model, they record it on butcher paper and complete worksheets about oxygen.
Curated OER
TE Activity: Muscles, Muscles Everywhere
Students study three different muscle types and investigate the affect of space travel on astronauts' muscles. They examine how exercise has a positive affect on muscle both on Earth and in space while looking at engineers' roles in...
Curated OER
TE Activity: The Beat Goes On
Students determine what the pulse is before examining how to measure the heart rate in different situations. They build a simple device that measures the heart rate, take heart rates, and record them on a worksheet. They discuss how...
Curated OER
Walk, Run, Jump!
Students participate in a series of timed relay races using their skeletal muscles. They compare the movement of skeletal muscle and relate how engineers help astronauts exercise skeletal muscles in space. They list the three types of...
Curated OER
SALLY RIDE
Students express what it would be like to launch off into outer space in a space shuttle. They include what it might feel like, look like, sound like, and any thoughts that go through their mind as they dart away from the Earth's...
Curated OER
Dayna Lykins, Leanna Prater
Fourth graders compare and contrast gliding flight and true flight. They investigate the basic principles of aeronautics. The class participates in activities to observe lift and the effect of air. Students design and fly their own...

How Big is the Sun? Exploring the Size and Scale of the Sun, Earth and Moon
Students explore the relative sizes of the Sun, Earth and Moon as they make an impressive large-scale model for classroom use throughout the unit.
Curated OER
TE Activity: Testing the Caverns
Students make model caverns out of paper mache or clay. They bury them in a tray of sand, and test the models by dropping balls into them simulating as asteroid hitting the earth. They discuss the results of the activity in a whole class...
