Astudent designs an experiment where she will put the same amount of air into three different balloons. one balloon will be submerged in ice water, one balloon will be carefully heated with a hair dryer, and the last balloon will be left alone. after making the changes, the student then will then measure the diameter of each balloon. the dependent variable is:

hypothesising or postulating

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
