In an activity, students create models of landscapes by cutting two-liter plastic bottles
in half lengthwise and filling them with different combinations of soil, sand, pebbles,
and small plants. After positioning the models at an angle, the students pour equal
amounts of water onto each mode;l's raised end and collection the runoff in beakers
placed under each model's lower end. The students then determine the dry mass of
the sediment contained in the runoff from each model. Which of the following
scientific questions can the students investigate more directly in the activity
described? A. How can growing plants break apart rocks? B. Do earthworms improve
soil fertility? C What are some factors that affect erosion ? D. Does temperature affect
weathering rates?

Researchers are measuring surface salinity in different areas of an ocean. In which of
the following areas will the researchers most likely find the highest surface salinity? A.
An area in which cooler temperatures are causing heavy rainfall. B. An area in which
warmer temperatures are causing icebergs to melt. C. An area in which river flow is
causing a mixture of freshwater with seawater. D. An area in which warm, dry winds are
causing a high rate of evaporation .

Transfer and conservation of energy
Give this one a try later!
Conservation of Energy: The total change of energy in any system is always
equal to its total energy transferred into or out of a system. Energy cannot
be created or destroyed, but it can be transported from one place to
another and transferred between systems. Four ways energy can be
transferred: 1. Mechanically- by action of a force. 2. Electrically- by a
current. 3. Radiation- light waves or sound waves. 4. Heating- conduction,
convection or radiation.
Genetic engineering agriculture

A type of modern biotechnology used to modify the genome or genetic
material of living organisms. Can increase crop yields, reduce costs for
food and drug production, reduce need for pesticides, enhance nutrient
composition and food quality, resistance to pests and disease, greater food
security, medical benefits to the world's population.

As you dive down the light starts to fade, temperature drops, water
pressure feels crushing. Wavelength decreases and is refracted.
