SO WHICH CUBE IS IT?

SOME MORE OBSERVATIONS TO MAKE…

Awareness Test Whodunnit?

WHAT IS SCIENCE?

Mini Project:Question: What is Science?

Objective: To create a interpretation of what you think science is.

Materials: 8.5 x 11 Sheet of paper (computer paper), pictures (clip art, Google images, draw), words or you may use GlogsterEDU to create your project. To use GlogsterEDU see Mrs. Vidito’s links page for directions. GlogsterEDU

Procedure: 1. Create a mini-poster to answer the question: What is Science?2. Poster needs to include ONLY 5 – 10 pictures and ONLY

5-10 wordsa Need to include the skills of a scientist, branches of science and how scientist solve questions.b. Needs to be neat and organizedc. Name, date and class color in upper right hand

WHAT ARE THE BASIC SKILLS OF A GOOD SCIENTIST?

LAB 1A: MISSION POSSIBLE

LAB 1B: MYSTERY CUBE

WHAT SKILLS DID YOU NEED TO SOLVE THESE PROBLEMS?

LAB 1A: MISSION POSSIBLE LAB 1B: MYSTERY CUBE

A. Observing: using the five senses to gather information about the world

B. Inferring: making a conclusion based on your observations

C. Predicting: using past experience or current evidence to make an inference about the future

D. Classifying: grouping together similar itemsE. Making Models: helps us to understand things we

cannot seeF. Communicating: the process of sharing ideas

and information

What do all these processes share and how are they different?

THE EXPERIMENT OR THE INVESTIGATION

WHAT DOES A GOOD EXPERIMENT CONTAIN?

•Testable hypothesis•Identify and limiting the variables•Ensuring constants within the experiment •Qualitative data – descriptive data•Quantitative data – numeric values•Using Models•Having multiple trials•Designing data tables to organize information•Eliminating bias: (to have a preference - opinion)•Using standardized units of measure•Being safe•Finding materials

Hypothesis: an educated guess that can be tested An if…then statement Will either be supported or not supported – never

right or wrong!

Shows a relationship between the independent and dependent variable.

A FEW MORE DETAILS… THE HYPOTHESIS

If a plant is talked to then the plant will grow bigger.

Variables: Independent Variable: is the variable changed

by the scientist There is always only ONE! Also known as the manipulated variable

Dependent Variable: is a measure of how the independent variable responds

Also know as the responding variable Quantifiable value (a number usually)

TESTING THE HYPOTHESIS

Measure the growth of each

plant

Talking to plants: plant A – 1minPlant B – 2 minPlant C – 3 minPlant D – 0 min

Control: within an experiment one setup will not have the independent variable applied.

This setup is used measure if the independent variable is causing change. NOT EVERY EXPERIMENT HAS A CONTROL.

Constants: quantities that will remain constant within an experiment

Question Independent Variable(What I changed)

Dependent Variable( What I observed or

measured)

Controlled Variables(What I keep the

same)

How much water flows through a faucet at different openings?

Does heating a cup of water allow it to dissolve more sugar?

Does fertilizer make a plant grow bigger?

Do different brands of candles burn faster?

Who listens to the most music: teenagers or parents?

Is the classroom noisier when the teacher leaves the room?

Do bicycle fenders keep the rider dry when riding through a puddle?
