What advantage does NISAR have over a single-band radar system? - ANSWER
✓ NISAR can gather twice the data because it uses two different radar
frequencies.
Why two radar bands matter - ANSWER ✓ L-band penetrates deeper into
vegetation and soil, while S-band is better for surface details.
What advantage does using L-band and S-band give NISAR? - ANSWER ✓
Different frequencies interact with Earth's surface differently, helping scientists
study vegetation, soil moisture, land movement, and ice more accurately.
Objectives of the Lesson Plan - ANSWER ✓ Discuss the roles of NASA and
ISRO in the NISAR mission. Investigate how radar bands capture data about the
planet.
Practice transforming numerical data into visual information.
Materials (lesson plan) - ANSWER ✓ NiSAR Slides, Shoebox, 2 Different sized
skeweres or straws, Thin Fabric, Assorted Items to create simulated Earth terrain,
hot glue, earth mapping handout
- ANSWER ✓ NISAR uses 2 different types of electromagnetic waves to gather
different types of data. The 2 kinds of waves NISAR use are in the microwave part
of the electromagnetic spectrum.
Where on the electromagnetic spectrum are the waves NISAR uses located? -
ANSWER ✓ They are in the microwave part of the electromagnetic spectrum.
, How many types of electromagnetic waves does NISAR use? - ANSWER ✓
NISAR uses two different types of electromagnetic waves.
L-Bands - ANSWER ✓ transmit all the way to the ground and will be used for
surface imaging and soil moisture
What type of waves are also used in GPS Satellites? - ANSWER ✓ L-Bands
Which instruments were provided by NASA? - ANSWER ✓ L-Bands
S-Bands - ANSWER ✓ do not transmit as far and will be used to measure
vegetation.
What types of waves are typically used for communication? - ANSWER ✓ S-
Bands
Which instruments were provided by ISRO? - ANSWER ✓ S-Bands
What do the instruments on NISAR measure? - ANSWER ✓ The time it takes for
a wave to bounce back & any changes that occured between the wave that was
emitted & the one that was recieved. That data is translated into surface &
vegetation images.
Tangible Examples - ANSWER ✓ If you played a game of telphone blindfolded,
you could estimate the number & ages of participants by the clarity of the message
& the rate it returned to you. If the message cam back exactly as you sent it, it
likely was passed through 1 or 2 adults. If the message took several minutes to
return, it likely was passed through many people.
You can bounce a ball off the floor, & it returns toyour hand. If you bounce the
ball off a table, it returns to your hand more quickly. Even if you did this in the
dark, you would be able to tell that the second object was taller than the first.
What will be used to represent the 2 bands of waves in the activity? - ANSWER
✓ Skewers
What will we measure instead of the time it takes waves to bounce back? -
ANSWER ✓ The height of the skewers protruding above the thin fabric
