STEM videos for Elementary School students
Students will learn about
stress, strain, tension, compression, and how these concepts are important
during the designing and building processes. By utilizing spaghetti as their
building material, students will explore the forces at work on a bridge and
will test the strength of their own spaghetti bridge
involves testing how five different substances behave when treated with water
and observing and recording their physical and chemical properties. This will
facilitate discussions on the different states of matter and how to compare,
contrast, and categorize different substances. The concepts of conservation of
mass and that all matter is made of particles too small to be seen will be discussed. Continued observations over a
week will enhance and reinforce these concepts.
into the process of erosion and environmental factors that influence the degree of erosion will be conducted.
Students will complete several experiments exploring the factors that slow down
or speed up the process of erosion. The effects of erosion on our environment
will also be discussed.
This lab investigates the force of gravity by
carrying out “speed sinking” races using beans of different size and shape. The
beans will be dropped into containers of water. Students will investigate the
effects of resistance on the speed of sinking. A final, classic demonstration
of objects falling in a vacuum will be used to illustrate this effect.
This experiment serves as an introduction to or
reinforcement of concepts relating to measurements. Through a series of
investigations, students will become more familiar with different tools that
are used by scientists, as well as everyday household items that are designed
specifically for measuring. Some concepts that will briefly be discussed are
scale, uncertainty, and accuracy in measurements.
