To solve this problem, we need to calculate the new amount of electricity Dr. Frankenstein plans to use after increasing the initial amount by 5%.

### Solution Steps:

1. **Identify the initial amount**: The initial amount of electricity is 30 watts.
2. **Calculate the increase**: We need to increase this amount by 5%.
   - \( 5\% \) of 30 watts is calculated as:
     \[
     \text{Increase} = 30 \times \frac{5}{100} = 1.5 \text{ watts}
     \]
3. **Find the new total**: Add this increase to the original amount.
   - New amount of electricity = \( 30 + 1.5 = 31.5 \) watts.

### Answer:
Dr. Frankenstein will need to use **31.5 watts** of electricity.

Here are some related questions to explore:

1. What would the new electricity amount be if he increased it by 10% instead?
2. How much electricity would he need if he started with 50 watts and increased it by 5%?
3. If Dr. Frankenstein used only 25 watts, what would a 5% increase look like?
4. How would you calculate a 15% increase on 30 watts?
5. Can you convert 5% to a decimal and use it directly in calculations?

**Tip**: When calculating percentages, converting the percent to a decimal (e.g., 5% to 0.05) makes multiplication straightforward.

Dr. Frankenstein tried using 30 watts of electricity to power his monster to life. It didn't work. The doctor now wants to increase the electricity by 5% to see if he can get his monster to come alive. How much electricity is Dr. Frankenstein going to use?

Learn how to calculate a 5% increase on 30 watts of electricity, as Dr. Frankenstein attempts to power his monster. This problem introduces basic percentage calculations, ideal for students in Grades 5-6.
