Worksheet on temperature control in space for students to find supporting evidence.

Problem Analysis:

The task requires identifying and summarizing evidence from the provided text that supports the importance of controlling temperatures for astronauts while in space. The goal is to extract key points from the passage and explain how they support the inference.

Solution:

#### Step 1: Understand the Passage
The passage discusses why temperature control is crucial for astronauts in space. Key points include:
1. Earth's Atmosphere vs. Space: Earth's atmosphere regulates temperature, making it suitable for life. In space, there is no such regulation.
2. Thermal Challenges in Space: Temperatures can vary drastically in space, which poses a significant challenge for astronauts.
3. NASA's Role: NASA developed thermal technology (e.g., suits and blankets) to protect astronauts from extreme temperatures.
4. Applications: This technology is used in spacesuits, the International Space Station, and the entire space capsule to ensure astronauts' comfort and safety.

#### Step 2: Identify Evidence
The following pieces of evidence from the passage support the importance of temperature control for astronauts:
- Extreme Temperature Variations: "astronauts leave the International Space Station and float along the outside. There, they face very different temperatures."
- NASA's Development of Thermal Technology: "Special technology like Mylar has been made into suits and blankets to keep astronauts from freezing."
- Use of Heating Elements: "Heating elements throughout the astronaut’s suit make it possible to stay warm while the scientists do their space walks."
- Protection in the Entire Space Capsule: "That same technology is used to insulate the entire space capsule to protect everyone on board."

#### Step 3: Summarize the Evidence
The evidence highlights that:
1. Space lacks a stable temperature environment, unlike Earth, where the atmosphere regulates temperatures.
2. Astronauts face extreme temperature variations both inside and outside the spacecraft, which can be life-threatening.
3. NASA has developed advanced thermal technologies (e.g., Mylar-based suits and blankets, heating elements) to protect astronauts from these extremes.
4. Temperature control is essential not only for spacesuits but also for the entire space capsule, ensuring the safety and comfort of all crew members.

#### Step 4: Explain the Importance
The evidence collectively shows that without effective temperature control:
- Astronauts would be exposed to dangerously cold or hot conditions, risking hypothermia or heatstroke.
- Missions could fail due to equipment malfunctions caused by extreme temperatures.
- The survival and well-being of astronauts depend on maintaining a controlled thermal environment.

Thus, temperature control is critical for enabling safe and successful space exploration.

Final Answer:

The evidence supporting the importance of controlling temperatures for astronauts in space includes:
1. Extreme temperature variations in space pose significant risks to astronauts.
2. NASA has developed specialized thermal technologies (e.g., Mylar suits, heating elements) to protect astronauts.
3. These technologies are used not only in spacesuits but also in the entire space capsule to ensure safety and comfort.

Boxed Final Answer:
\boxed{
\text{Evidence: Extreme temperature variations in space, NASA's development of thermal technologies, use of heating elements, insulation of the entire space capsule.}
