People drop their phones all the time! It’s estimated that 95 million people drop their phones every year. To protect a phone, a cost-effective case that meets certain criteria is needed.

Your Task

In the following questions, you will design a solution that protects a phone from colliding with the ground and is inexpensive based on Newton’s Third Law.

Question 4
Use the table to answer the following questions.

Table 1: Features of Cell Phones Cases and Drop Distance Rating and Price of Phone Case Models

Question 3:

Based on the information in Table 1 about the structure and function of each phone case. Write a claim about the case that you believe is the most protective. Provide reasoning and support with evidence from the table to support your claim. answer the question using the Claim, Evidence, and Reasoning model.

(3 points)
Claim: The most protective phone case is
C
.

Evidence (use the information from the table to tell me about your evidence): According to the table, this brand case is/has
.

Reasoning: This evidence supports the claim because a phone case with
is more likely to protect the phone from falls.

Question 5
Question 4:

Compare and contrast the Price and Drop Distance data of the different phone cases found in Table 1.

Part A: Rank each brand from the best protection to the worst protection, where the best protection is at the top of the list and the worst protection is at the bottom of the list.

Arrange responses in the correct order to answer the question. Select a response, navigate to the desired position and insert response at that position. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can be moved using the up and down arrow keys or by dragging with a mouse.
Question 6
Part B: Rank each brand from the best price to the worst price by putting, where the lowest price is at the top and the highest price is at the bottom.(4 points)

Question 7
Question 5
You are looking for a phone case that is inexpensive and provides a significant amount of protection. Based on the information in Question 4, write a claim stating which phone case is the best for your budget. Use the Claim, Evidence, and Reasoning model to answer the question. Include your rationale on screen protectors, weight, special features, drop distance, and price.(3 points)
Claim: The phone case that best meets my budget and protection needs is
.

Evidence: According to the evidence in Table 1, this brand will protect my phone because it
and will be the best for my budget because it costs
.

Reasoning. This evidence supports the claim because the phone case will protect my phone and the cost is reasonable.

Question 8
Question 6

You have been given access to a science lab that creates and tests phone protectors. Redesign the case you choose in Question 5 to make it more protective and/or a lower price. You can take two cases and combine features to make a new, updated case, or suggest new modifications that are not included.

A: Describe your new smartphone case.

1 answer

Sure! Here’s a structured approach to each question based on the content provided.

Question 1

Part A: List all forces acting on each other when we drop a smartphone on the ground.

  • Gravity
  • Air Resistance
  • Normal Force

Question 2

Part B: Fill in the blanks to complete the model illustrating all the forces acting on the phone and the ground.

  • Phone: Gravity
  • Ground: Normal Force
  • Interaction: Air Resistance

Question 3

What percentage increase occurred in cases where individuals accidentally dropped their phones into toilets compared to incidents of phones being dropped on the ground?

  • 15%

Question 4

Question 3: Claim about the most protective phone case using Claim, Evidence, and Reasoning model.

  • Claim: The most protective phone case is C.
  • Evidence: According to the table, this brand case is/has a 12 ft drop distance rating and reinforced corners.
  • Reasoning: This evidence supports the claim because a phone case with greater drop distance protection is more likely to protect the phone from falls.

Question 5

Part A: Rank each brand from best protection to worst protection based on Drop Distance data.

  1. Brand A
  2. Brand C
  3. Brand B
  4. Brand D

Question 6

Part B: Rank each brand from best price to worst price.

  1. Brand D
  2. Brand B
  3. Brand A
  4. Brand C

Question 7

Claim about the best phone case for budget and protection needs.

  • Claim: The phone case that best meets my budget and protection needs is Brand B.
  • Evidence: According to the evidence in Table 1, this brand will protect my phone because it has a high drop distance rating of 8 feet and will be the best for my budget because it costs $20.
  • Reasoning: This evidence supports the claim because the phone case will protect my phone and the cost is reasonable.

Question 8

A: Describe your new smartphone case. The new smartphone case will combine the shock-absorbing materials from Brand A with the lightweight design of Brand D. It will feature reinforced corners, a silicone exterior, and an inner layer of gel padding to absorb impacts. Additionally, it will include a built-in screen protector that is scratch-resistant and will cost approximately $25.

Question 9

B: Explain how your updated design optimizes phone protection and applies knowledge about Newton's Third Law. The updated design optimizes phone protection by using materials that absorb and distribute the force of impact, consistent with Newton's Third Law which states that for every action, there is an equal and opposite reaction. When the phone hits the ground, the case absorbs the shock, reducing the force experienced by the phone itself.

Question 10

Identify the Independent, Dependent, and Control Variables.

  • Independent Variable: Height dropped
  • Dependent Variable: Damage to the phone on impact
  • Control Variables: Type of flooring, type of phone in the case, and environmental conditions during the drop test
