Ocean Currents and Atmospheric Effects

Second grade students visit Susan Shambach's science lab weekly for hands-on experiments. They learn about meteorology, specifically why the sky appears blue due to light scattering. An experiment using a beaker of water and milk demonstrates this concept, showing how light changes color similar to sunrise and sunset. Following this, students begin a unit on ocean currents, focusing on wind-driven currents and the Gulf Stream. They create drift bottles to track ocean currents, linking their studies to real-world applications.

Why does the sky appear blue to us?

• Because the sun emits blue light

• Due to the scattering of blue light by dust particles

• Because blue is the most dominant color in the spectrum

• Due to the reflection of the ocean

What is the educational benefit of the hands-on experiments in Susan's lab?

• They prepare students for exams

• They provide entertainment

• They offer practical understanding of scientific concepts

• They help students memorize facts

What does the addition of milk to the beaker of water represent in Susan's experiment?

• The earth's surface

• The sun

• The atmosphere

• The ocean

What colors are typically seen during sunrise and sunset?

• Black and white

• Purple and brown

• Red and yellow

• Blue and green

Why do we see red and yellow colors during sunset?

• Because the sun is closer to the earth

• Due to the reflection of the ocean

• Due to the scattering of shorter wavelengths

• Because the sun is setting through more atmosphere and dust

What is the primary focus of the ocean currents unit?

• Marine life

• Ocean pollution

• Wind-driven currents and the Gulf Stream

• Tides and waves

What is the significance of the Gulf Stream in the ocean currents unit?

• It controls the tides

• It causes ocean pollution

• It is a major source of marine life

• It is a significant wind-driven current

What is the purpose of the drift bottle activity?

• To observe marine life

• To collect ocean water samples

• To track the distance traveled by ocean currents

• To measure the temperature of the ocean

What do students use to seal the drift bottles?

• A cork

• A metal lid

• A plastic cap

• A message

Where will the drift bottles be released?

• In a local river

• At the coast

• In a swimming pool

• In a lake
