The deepest parts of the Grand Canyon are 1.6 kilometers deep.

Freezing water expands, breaking apart rocks.

Zinc oxide blocks sunlight effectively in sunscreens.

A high SPF indicates longer-lasting sunscreen protection.

Used in sunscreen experiments to allow most sunlight to pass through.

SPF measures how well a sunscreen absorbs UV radiation.

Titanium dioxide was not listed as a sunscreen ingredient in the experiment.

The Colorado River flows through the Grand Canyon.

Their northward and southward migratory routes differ.

Golden plovers winter south and southwest of their breeding grounds.

Golden Plover migratory routes have shifted away from coastal areas in the past decade.

Student 1 attributed differences in soil moisture on slopes to differences in solar radiation.

Student 2 thought that rainfall caused the differences in soil moisture.

The students measured soil moisture, solar radiation and rainfall for their investigation.

Rainfall affects soil moisture levels as per findings of the students.

The students calculated average measurements and uncertainties associated with the recorded data.

Normal rain is slightly acidic due to absorbed carbon dioxide.

Sulfur oxides and nitrogen oxides are partly responsible for the acidity of acid rain.

A marble chip immersed in vinegar overnight will lose mass and weight less than 2.0 grams.

A large number of visitors to the Grand Canyon cause erosion from walking trails.

Earth's crust movements contributed to the formation of the Grand Canyon.

Scientific investigation can study the erosion caused by walking tracks on the Grand Canyon.

A concern is whether the Grand Canyon is as beautiful as it was 100 years ago.

To compare sunscreens for effectiveness of protection.

High SPF sunscreens protect for longer periods compared with low SPF ones.

Zinc oxide effectively blocks sunlight.

Mineral oil in sunscreen experiments allows most sunlight through to compare against other sunscreens.

Mimi and Dean put drops of each sunscreen on light-sensitive paper to evaluate their effectiveness.

Light-sensitive paper changes color based on exposure to sunlight, indicating protection levels of sunscreens.
