What are the units of length?

Meters

What are the unit for mass?

Grams

What are the units for the volume of a liquid?

Liters

What are the units for the volume of a solid?

Cubic centimeters (cm 3 )

What are the units of Density?

g/mL or g/cm 3

What are beakers?

What is a triple beam balance?

What is an Erlenmeyer flask?

What is a graduated cylinder?

What is a Bunsen burner?

Mass/volume

What is the formula for density?

Accepted-Experimental Accepted X 100

What is the formula for percent error?

King Henry Died By Drinking Chocolate Milk

What is the mnemonic for the order of the metric prefixes?

L x W x H

What is the formula for volume of a regualar shaped object?

Water displacement (describe it)

What is the technique used for determining the volume of an irregular shaped object? Volume of water + object Minus Volume of water Volume of object

Accuracy

What is getting results that equal the “true” or “accepted” results

Precision

What is getting results that are repeatable or close together

To increase the accuracy of the data, you can gather precise measurements by reporting……

Your results with all marked (known) digits plus 1 estimated digit

SI Units

What are the standard units used in Science?

What MUST be included in a measurement

Value and a standard it is measured against (number and units)?

No matter what version of the scientific method you use, they all start with this

What is a Problem or question?

If… Then… because statement that predicts what will happen in an experiment

What is a hypothesis?

The difference between a scientific law and a scientific theory

Laws explain natural events without data. Theories are explanations of that result from years or research.

Data on the x axis of a graph

What is the independent variable (The variable “I” change)

Data on the y axis of a graph

What is the dependent variable (The variable I am measuring)

Final Jeopardy How many points are you going to risk? Scientific Notation

Complete the following chart Standard NotationScientific Notation x x

Standard Notation Scientific Notation Rule x Number less than 1 exponent is negative 1, x 10 2 Positive exponent number is greater than x Negative exponent number less than one x 10 4 Number greater than 1 exponent is positive
