Slide Deck

NGSA Science Sprint

Sharpening Your Science Skills for the Exam!

Objective: To practice NGSA-style science questions and identify key areas for review.

Welcome students and introduce the goal of the session.

What is the NGSA Science Exam?

The Next Generation Science Assessment evaluates your understanding of science concepts and your ability to apply scientific practices.

  • Focuses on Disciplinary Core Ideas, Science and Engineering Practices, and Crosscutting Concepts.
  • Practice helps you feel more confident and prepared!

Briefly explain what the NGSA Science Exam is and why practice is important.

Practice Problem 1: Ecosystems

A forest ecosystem experiences a sudden decrease in its deer population due to a new predator. Which of the following is the most likely immediate impact on the ecosystem?

A) An increase in primary producers (plants).
B) A decrease in the predator population.
C) An increase in the squirrel population.
D) A decrease in insect populations.

Introduce the first practice problem. Give students time to work on it.

Practice Problem 2: Chemical Reactions

When a student mixes two clear, colorless liquids, a white precipitate forms and the test tube feels warm. Which of the following best describes the evidence that a chemical reaction has occurred?

A) A change in state and a temperature change.
B) A color change and a change in volume.
C) A change in odor and a change in mass.
D) A change in shape and a change in density.

Introduce the second practice problem. Encourage students to think through the steps.

Practice Problem 3: Waves & Energy

A sound wave travels through air at a certain speed. If the frequency of the sound wave increases, but the medium remains the same, what happens to the wavelength and speed of the sound wave?

A) Wavelength decreases, speed increases.
B) Wavelength increases, speed remains the same.
C) Wavelength decreases, speed remains the same.
D) Wavelength increases, speed decreases.

Introduce the third practice problem. Remind students to consider all aspects of the question.

Time to Review!

Let's go over the practice problems together.

  • Share your answers and your reasoning.
  • Don't be afraid to ask questions!
  • We'll use the NGSA Practice Answer Key to guide our discussion.

Transition to reviewing the answers. Emphasize understanding the 'why' behind each answer.

Keep Practicing!

Consistent practice is key to success!

  • Review the NGSA Practice Answer Key for detailed explanations.
  • Identify topics where you need more practice.
  • Ask your teacher for additional resources!

You've got this!

Provide encouraging words and outline the next steps for continued preparation.

Answer Key

NGSA Practice Answer Key


Part 1: Multiple Choice Questions

Question 1: Ecosystems

Correct Answer: A) An increase in primary producers (plants).

Explanation: Deer eat plants. Fewer deer mean more plants. Option B, C, and D are less direct impacts.

Question 2: Chemical Reactions

Correct Answer: A) A change in state and a temperature change.

Explanation: A precipitate forming is a change in state (liquid to solid), and the test tube getting warm is a temperature change. Both indicate a chemical reaction.

Question 3: Waves and Energy

Correct Answer: C) Wavelength decreases, speed remains the same.

Explanation: Wave speed depends on the medium. If the medium (air) is constant, speed is constant. If frequency increases and speed is constant, wavelength must decrease (v = fλ).

Question 4: Cell Biology

Correct Answer: C) Mitochondrion

Explanation: Mitochondria are responsible for cellular respiration, which generates most of the ATP (energy) in eukaryotic cells.

Question 5: Earth Systems

Correct Answer: C) Increased runoff and sediment in rivers.

Explanation: Trees and plants help absorb rainwater and hold soil in place. Without them (deforestation), rain runs off more quickly, carrying soil into rivers. This leads to increased runoff and sediment.

Part 2: Open-Response Question

Question 6: Scientific Investigation

A scientist is investigating the effect of different fertilizers on plant growth. They set up three identical groups of plants. Group A receives fertilizer X, Group B receives fertilizer Y, and Group C receives no fertilizer. All plants are given the same amount of water and sunlight and are grown in the same type of soil.

A) Identify the independent variable and the dependent variable in this experiment.

Answer:

  • Independent Variable: The type of fertilizer used (Fertilizer X, Fertilizer Y, No fertilizer).
  • Dependent Variable: Plant growth (e.g., height, mass, number of leaves).

B) Explain why it is important to keep the amount of water and sunlight the same for all groups.

Answer: It is important to keep the amount of water and sunlight the same for all groups to ensure that these factors do not influence plant growth. If water or sunlight varied, the scientist wouldn't know if changes in plant growth were due to the fertilizer or to differences in water/sunlight. These are controlled variables that must be kept constant to isolate the effect of the independent variable on the dependent variable.
