A Hummingbird's Delight: Calculating the Weight Difference Between Two Eggs

Hummingbirds are known for their remarkable abilities, including their impressive flying skills and their unique nesting habits. One fascinating aspect of hummingbird biology is their nesting behavior, where they carefully construct intricate nests to lay their eggs. In this article, we will delve into the world of hummingbird nests and explore a mathematical problem related to the weight of two eggs found in a hummingbird nest.

A hummingbird nest has two eggs. Egg A has a weight of $8.8 \times 10^{-3}$ pounds, and Egg B has a weight of $2.2 \times 10^{-3}$ pounds. How many pounds greater is the weight of Egg A than the weight of Egg B?

Step 1: Understand the Problem

To solve this problem, we need to understand the concept of weight difference. The weight difference between two objects is the absolute value of the difference between their weights. In this case, we need to find the weight difference between Egg A and Egg B.

Step 2: Calculate the Weight Difference

To calculate the weight difference, we need to subtract the weight of Egg B from the weight of Egg A. This can be represented mathematically as:

Weight difference = Weight of Egg A - Weight of Egg B

Substituting the given values, we get:

Weight difference = $8.8 \times 10^{-3}$ - $2.2 \times 10^{-3}$

Step 3: Perform the Calculation

To perform the calculation, we need to subtract the two values. Since both values are in scientific notation, we can subtract the coefficients and keep the exponent the same.

Weight difference = $8.8 - 2.2 = 6.6 \times 10^{-3}$

In conclusion, the weight of Egg A is $6.6 \times 10^{-3}$ pounds greater than the weight of Egg B. This problem demonstrates the importance of understanding scientific notation and performing calculations with precision.

This problem may seem trivial, but it has real-world applications in various fields, such as:

Biology: Understanding the weight difference between eggs can help biologists study the reproductive habits of hummingbirds and other birds.
