Variables 8 th Grade Science
Does the mass of a derby car affect its speed? Scientific Question (problem):
What is being tested or compared in an experiment. It is what the experiment is all about It is the cause. It is the before
What is being tested or compared? Does the mass of a derby car affect its speed?
The outcome or the results of the experiment What is being measured. It is the effect. It is the after.
What is being measured? Does the mass of a derby car affect its speed?
How to Write a Hypothesis Describe the relationship between the IV & DV: –The more/less of the _IV_, the more/less the ___DV__.
The Hypothesis should predict… As the IV (increases or decreased), the DV (increases or decreases).
Hypothesis The more mass the car has, the faster it will go. or The less mass the car has, the faster it will go.
Constant Variables Stay the same throughout the experiment
Constants Race course (distance, steepness, etc) Wheel size Shape Same kind of wood/brand Drop time (release levers)
Control (normal) – plain wooden car Experimental Group- Different weights added to car
2 nd Daily Question: Write hypothesis & complete design chart Does the shape of the pinewood derby car, affect its speed? Hint: use word aerodynamics
LN # 1 Scientific Methods. Science The word science comes from the Latin verb meaning to know. In science observations lead to questions about the natural.
Steps of the Scientific Method. What is the scientific method? The Scientific Method involves a series of steps that are used to investigate a natural.
Scientific Method. Observations Observations are made with your five senses. (Sight, taste, touch, hearing, smell) They are measurable facts and not opinions.
The smallest shark is the tsuranagakobitozame : a Japanese name that means, “dwarf shark with a long face,” also called dwarf dog-shark. This shark can.

Activity 76 Follow-up Is there a correlation between cart speed and block movement? Did the collision at different cart speeds last for different lengths.
8/15/12 We want to see if running with weights on improves speed. Using 5, 10, 15 lb vests – be able to tell the 4 parts of the experiment that is needed.
The Scientific Method. The Scientific Method involves a series of steps that are used to investigate a natural occurrence.
What is science?. What do scientist do? Scientist observe the world around them and ask questions to understand how things work.
The Scientific Method involves a series of steps that are used to investigate a natural occurrence.

Introduction to the Scientific Method: Planning an Investigation.
Session 1. What are variables? The difference between independent, dependent and controlled variables. Examples What are variables? The difference between.
Definitions ?. The dependent variable is the variable that is being measured in an experiment.
Designing an experiment: An experiment is an organized procedure to study something under controlled conditions.
Scientific Method. Steps in the Scientific Method Observation Observation Hypothesis Hypothesis Experiment Experiment Data Collection Data Collection.
Internal Assessment Your overall IB mark (the one sent to universities after the IB test) in any IB science course is based upon two kinds of assessments.
1.3: Scientific Thinking & Process Welcome to the Scientific Method!!!!!!
The Scientific Method. Steps of the Scientific Method The Scientific Method is used by all Scientists The Scientific Method is made up of many parts called.
