Scenario 2 biology students prepared five 2-liter beakers of water at the following temperatures: 18 °c, 22 °c, 26 °c, 30 °c, and 34 °c. the temperature of the aquarium in their classroom was 22 °c so they used that temperature as their control. they removed goldfish from their aquarium and placed three in each beaker. for five minutes, they counted and recorded number of times the gill covers opened and closed for every goldfish. constant

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.
