How does the absence of gravity affect the human body? The skeletal system, circulatory system, and the sense of balance are all impacted. With a very casual tone, an astronaut explains the changes to these body systems and also an experiment done by neuroscientists on underuse of organs. The video is presented as if you are in a spacecraft viewing each topic within a window. Although it doesn't directly meet science standards, it would be an interesting addition to a unit on space exploration. Follow it with a discussion about why astronauts need to be in top physical condition before embarking on a mission.
Seventh graders determine the center of gravity of an object. They get card stock objects to balance on pencil eraser and a meter stick to balance with same # of weighted string(s) on each side. They get meter stick to balance with 2 weighted strings on 1 side and 1 weighted string on the other.
What goes up must come down, but there is more to the phenomenon than meets the eye! As it turns out, any two objects attract to each other. The formula for Newton's law of universal gravitation is introduced in the explanation. A touch of humor in this video makes it entertaining to most middle schoolers, so consider showing it in your earth science, astronomy, or physical science class.
Third graders discover the effects upon gravity caused by mass and distance of the gravitational force between two objects. Using toy cars and a ramp, they add more weight to their cars and measure the distance they travel from the top of the ramp to the stopping point. Once they have experimented numerous times, 3rd graders compile their information into a bar graph.
Fifth graders explore the basic concepts of gravity in relation to Newton's law of gravity. They collect data about their experiments and include the gravitational influence on movement. They search the Internet to get a historical perspective of Newton, his discoveries and the physics involved with NASA and the space shuttle flights.
Middle schoolers investigate the force of gravity and how it effects different objects that are put into acceleration when applied the experiment of free falling. They drop different objects that have a variety of masses and some that cause air resistance. They make observations and record the findings.
Learn how to measure weight with newtons in a science experiment about gravity. After they read a short paragraph about force, fifth graders draw an arrow to indicate which way a spring is being pulled. Next, they survey their family members to see which of them has the greatest response to gravity.
Students use the graphing calculator and the core equation: y=Ax^2+Bx+C where A = the acceleration of gravity/2, B = the initial velocity, and C = initial height above ground to graph parabolas for Earth and Mars. They experiment with holding different co-efficients constant and viewing the results.
Students investigate the concept of gravity. In this physics lesson, students view a demonstration of the concept of gravity by using glue. Students identify why the glue won't go up into the air when the bottle is squeezed. Students draw a picture of something that will fall to the ground and another picture of an object that stays up.
