.325 as a Fraction

 

Summary

• Converting a Decimal to a Fraction: The process involves placing the decimal value over one and then multiplying both the numerator and the denominator by a power of 10 to eliminate the decimal. This is determined by the number of places the decimal point needs to be moved to the right. • Simplifying the Fraction: The resulting fraction is then simplified by dividing both the numerator and the denominator by their common factors until the fraction is in its simplest form. • Final Result: The conversion of 0.325 to a fraction results in 13/40 after simplification.

Independent Variable Summary and Worksheet

 

The video from MooMooMath and Science explains the difference between independent and dependent variables in a science experiment:

Independent Variable (Manipulated Variable):The variable you change in an experiment.

It can stand alone and is manipulated to observe its effect.

Example: In an experiment testing if car color affects inside temperature, the color of the car is the independent variable.

Dependent Variable (Responding Variable):

The variable you measure; it depends on the independent variable

Example: In the car color experiment, the temperature inside the car is the dependent variable.

Examples from the video:

Tree height and water: Water amount = independent; Tree height = dependent.

Bananas and blood pressure: Number of bananas = independent; Blood pressure = dependent.

Graphing Tip: Use "DRY MIX":

DRY = Dependent, Responding, Y-axis.

MIX = Manipulated, Independent, X-axis.

Making Change - Counting Up

 

This video teaches how to make change using the counting up method instead of subtraction. The idea is to count from the cost of an item up to the amount paid, which helps in calculating change more intuitively.

Example 1:

Item cost: $18.76

Amount paid: $20.00

Counting up:

Add $0.04 → $18.80

Add $0.20 (two dimes) → $19.00

Add $1.00 → $20.00

Total change: $0.04 + $0.20 + $1.00 = $1.24

Example 2:

Meal cost: $11.13

Amount paid: $15.00

Counting up:

Add $0.02 → $11.15

Add $0.10 → $11.25

Add $0.75 (three quarters) → $12.00

Add $3.00 → $15.00

Total change: $0.02 + $0.10 + $0.75 + $3.00 = $3.87

Conclusion:

Using the counting-up method makes giving change simpler and helps avoid subtraction mistakes. The video ends with a positive message: “Kindness multiplies kindness – be kind to someone today.”

Freshwater Biome - Free Worksheet and Summary

 

This video provides an overview of freshwater biomes, which make up only 2.5% of Earth's water. Major types include ponds, lakes, rivers, streams, and wetlands. Organisms in these biomes are adapted to low salt content, as freshwater contains only about 5 parts per thousand salt compared to 30–50 in saltwater.

• Rivers and Streams: Water flows in one direction from the headwater to the mouth. Flow speed depends on the slope; faster water prevents buildup of organic materials.

• Lakes and Ponds: These are standing inland water bodies, varying in size and permanence. Some ponds may be seasonal, while lakes can be hundreds of years old.

• Wetlands: These saturated areas (marshes, swamps, bogs) support diverse aquatic plant life like cattails and willows, and host many species of amphibians, reptiles, and birds.

Grasslands Biome - Free Worksheet and Summary

 

Temperate Grasslands - Overview:

Location: Found in South Africa, Hungary, Argentina, Uruguay, Russia, and the central plains of North America.

Vegetation: Dominated by grasses; trees and large shrubs are mostly absent.

Climate: Hot summers and cold winters; seasonal droughts and occasional fires are common.

Rainfall: Moderate, mostly in late spring and early summer (20–35 inches annually).

Soil: Deep, dark, and very fertile due to the growth and decay of grass roots.

Flora and Fauna:

Some trees like oaks and willows, and various flowers.

Animals include gazelles, zebras, rhinos, wild horses, lions, prairie dogs, hawks, owls, snakes, and insects like grasshoppers.

Types:

Prairies: Tall grasses, more rainfall.

Steppes: Short grasses, less rainfall (10–20 inches annually).

Key Features:

Fertile soil ideal for agriculture.

Maintained by natural fires, droughts, and grazing, which limit tree growth.
