1. Question?
How does science affect you in your daily life?

2. Some different types of science
Biology
Astronomy
Meteorology
Chemistry
Geology
Hydrology

3. So, how does science impact me?

4. Bell Ringer
What does science mean to you?

5. What is Science?
An organized way of using evidence to learn about the natural world
Concepts cannot be made up

6. How do scientists think?
Start with observations
A process of gathering information in an orderly way
Example – my computer won’t start.
WHAT WOULD YOU DO?
Information collected is called data

7. 2 categories of data Quantitative – based on numbers
Ex) there are 5 eggs in the nest
she owns 75 pairs of shoes
Qualitative – descriptive information that involves characteristics and cannot be counted
Ex) the group appears to be happy
they must be hungry

8. What do we do with data Use it to make an inference
A logical interpretation based on prior knowledge or experience
Ex) OK drinking water?

9. Explaining and interpreting evidence
PROBLEM
What is the ball made out of? What would be your plan of action to try to answer the question?

10. What’s the ball made out of?
Compare and Contrast
Smell
Feel
Sound
(black box)
(scientific method graphic organizer)

11. Scientific Method State a problem and research it Form a hypothesis
“if _______, then ________” statements
A proposed scientific explanation
Done using prior knowledge, logical inference and informed/creative imagination

12. Scientific method Setting/Performing a controlled experiment
Write out detailed procedure and conduct
Only 1 variable changed at a time
3 variable types
Controlled – stays the same
Manipulated – deliberately changed
Responding –happens as a result of the manipulation
Observe, recording and interpret results
Drawing a conclusion
What happened?

13. LEGO Procedure Lab Can your procedure be replicated?
Behind a screen, assemble 10 blocks into an unusual structure. Write directions that others can use to replicate that structure without seeing it.
Exchange directions with another team. Replicate the team’s structure by using its directions.
Compare each replicated and original structure. Identify which parts of the directions were clear and accurate, and which were unclear or misleading.

14. Post LEGO lab questions
How could you have written better directions?
Why is it important that scientists write procedures that can be replicated?

15. LEGO Experiment (repeating experiments)
TB pg 2 inquiry question
What is your group going to have to do, in order for another group to replicate your LEGO structure correctly?

16. When you cannot experiment
Sometime need to observe in natural setting (field studies)
Sometimes experiments are not ethical
human/animal right controversies
So, they may try larger investigations
Ex) use a group already exposed to a substance

17. Result of many investigations
Theory – a well tested explanation that unifies a broad range of observations
a particular hypothesis that has evidence support from many investigations
May be dominant view, but not absolutely true

18. Biology The study of life What makes something live?
Needs to have the characteristics possessed by living things

20. Characteristics of Life - Video
Reproduce
Grow/Develop
Respond to Environment/ Move
Obtain & Utilize Energy

21. More Characteristics of Life
Adaptations
Made of Cells
Contain DNA
Maintain Homeostasis

22. Important Qualities of Biology
As organisms grow, they are able to evolve
Allows the living world to be very diverse
Among different organisms and similar organisms

23. Reinforcement. name the characteristic of life
Reinforcement name the characteristic of life described in each example.
That boy shot up five inches in only one year.
Our cat had a litter of kittens yesterday.
Eat a good breakfast and you will run longer.
When that car moved, our cat ran under the porch.
The owls night vision allows it to see mice on the darkest of night.
Single celled organisms live in that pond.
Your body normally maintains a temperature of 98.6 F.
Scientists can prove if 2 organisms are similar by looking at their chemical make-up.

24. Reinforcement. determine if the following
Reinforcement determine if the following describes a living or non-living thing.
Rust on a car
An apple on a tree
Bacteria
Lightning
Dinosaur Fossil
A wasp

25. How do we know all this stuff?
Remember…
Science is a collection of facts that are proven to be true through the use of research
Scientists use a series of steps to investigate answers to questions they may have
Scientific Method

26. Tools and Procedures
Use same standards in order to replicate procedures
Measuring – metric system (meter, liter, gram, Celsius)
Analyzing – tables and graphs
Microscopes – magnify images not seen by naked eye

27. Techniques Cell cultures – making many cells from 1 cell
Cell fractionation – separating 1 part of a cell from another
Safety – remember to always be SAFE!
