Fourth graders collaborated to create plant and seed models to demonstrate how adaptations promote seed dispersal. Presentations demonstrated how seeds are carried by wind, water and animals. The ingenuity and creativity shared by the groups showed their deep learning.
Third graders designed a working system with Dacta that included as least one simple machine. Featured are some excited engineers!
Fourth graders explained how a microscope enlarges objects.
Systems of Inclined Planes
Third graders designed and built systems with inclined planes. They used protractors to measure the angle of the ramp and centimeters to measure the distance various toy cars traveled.
Eggs, Eggs Everywhere
Kindergartens investigated how habitats meet the needs of organisms and drew likenesses of the observed habitats.
Effects of Heat
Second graders observed and recorded the effects of heat with the three states of matter: solids, liquids and gases. They were great at sharing and encouraging one another in their findings.
Heat Energy: Second graders made predictions and gathered evidence of heat's effect on objects such as marshmallows, chocolate, candles and toothpicks. They compared and recorded temperatures in Celsius and Fahrenheit and observed the effects of cold water and heat on special straws. They watched as "air holes" developed in steaming pancakes, tested thermal paper by touching it and saw how heat affects the surrounding air by dangling "paper spirals".
Fourth graders created a prototype of a boat with aluminum foil from their knowledge of buoyancy, density and displacement to explain how an ocean boat floats.
Fourth graders eagerly accepted the challenge of building a boat using only aluminum foil that would float and carry as much weight, measured with gram stackers, washers and gram bears, as possible. There were many smiles and a lot of sharing of new learning among these budding engineers.
Patterns of Movement - Second Grade
How do simple machines make work easier? Second graders described, drew examples and explained how the wheel and axle, lever, screw, inclined plane, pulley and wedge make work easier. They built many of these in lab.
To view some of the photos for Science Fair - 2017, select the Photo Album link on the side of this page.
Armstrong's Science Fair boasted over 100 exhibits, each one teeming with the scientific method, authenticity, aesthetic appeal, current scientific procedures, graphs, data, photos and actual materials. Congratulations to each participant! Keep "sciencing" !!
Third graders investigated Earth's landforms and how communities/civilizations are affected by them. In stations they worked together to form communities in mountain areas, hillsides, plateaus and plains.
