• Researching energy from the Sun

Sophie, a young scientist, noticed that her plant wasn't growing as well as it should. Match her actions that she took with the appropriate 4-steps of problem solving:

• Execute the Plan

• First, she took a close look at the plant and identified that its leaves were turning yellow.

• Identify the Problem

• She found out that yellow leaves might indicate a lack of sunlight or overwatering, and decided to try giving the plant more sunlight and less amount of water.

• Analyze the Results

• Sophie placed the plant closer to the window, and reduced the number of times she watered to once a week.

• Make a Plan

• After two weeks, she observed that the plant's leaves were becoming green again and the plant was growing taller, so she is happy with her results.

Match the following terms with the correct example

• Theory

• Albert Einstein explained "how" mass bends space-time to cause gravity.

• Hypothesis

• If you water plants with green tea, then they will grow taller than plants with plain water

• Law

• Isaac Newton describes "what" happens to objects in motion and objects at rest unless acted on by a Net Force

Scientists are conducting an experiment to understand the effect of different amounts of sunlight on the growth of bean plants. They set up four groups of bean plants: one group is exposed to sunlight for 3 hours a day, the second group for 6 hours, the third group for 9 hours, and the last group is kept in the dark. All plants are watered with the same amount of water, kept in the same type of soil, and placed in the same type of pots.
Match each term with its corresponding aspect from the experimental scenario:

• Dependent Variable

• The group of bean plants kept in the dark.

• Control

• The height of the bean plants after 3 weeks.

• Independent Variable

• The number of hours of sunlight each group of plants receives daily.

• Constant

• The type of soil used for planting the bean plants.

• Scatter Chart

Which of the following is NOT a standard SI Base unit?

• Mass = kilogram = kg

• Time = second = s

• Temp. = Kelvin = K

What is 2,560,000 in Scientific Notation?

• 2.56x10^(-6)
• 2.56x10^(6)
• 2.560000x10^6
• 256x10^(-4)

Convert 2,335 cm to km. Include units! Note* 1 cm = 10^-2 m & 1km = 10^3

We have a piece of metal copper that we measured to have a mass, m = 43.211 g. We know that copper has a density, D = 9.0 g/mL. Knowing that D=M/V, Calculate the Volume, V of our copper. Round your answer with correct number of Significant Figures, and in correct units.
