Have a great weekend!

Tuesday

Scientific method:

Make an observation

Ask a question

Make a hypothesis

design and conduct an experiment

Draw a conclusion

Remember to understand the difference between DEPENDENT and INDEPENDENT variables

Example-An experiment to determine how length of day effects plant growth.

Independent-Length of day
Dependent -Plant growth.

This too will be on the quiz this Friday

Monday!

Welcome back for week 2

This week we'll be focusing on three things:  The scientific method, sources of sampling error, and the metric sysytem.

There will be a quiz on this material on Friday!

Remember that everywhere in the world uses the metric system in science even here in the US, it is important to know the basic conversions because we too will using the metric system all year.

Tomorrow we're doing a lesson on sampling error, and a demonstration.

The four main reasons for sampling error are the following (this is what you should know for the quiz)

1) Rounding, Precision, and Accuracy
2)Sampling (when was the sample taken)
3) Technical and human error (nothing is perfect)
4) Unintentional bias
Tomorrow



The tving a bias

Tomorrow we get our books, make sure to bring your ID cards and leave the book at home ( we have class sets). 

The field of microscope work is called "Microscopy"

Today many of you were able to properly focus in on a specimen at 40 magnification, some even up to 400!  If you haven't been checked off yet be sure to get it done tomorrow in class.

The Scanning Electron Microscope is the most powerful microscope.
Here's a video of some amazing images into the micro world.

There will be a short quiz this Friday on the seven properties of life, this is what you need to know

 

Chpt.1-4: Properties of Life Notes

 

What is biology?

Biology is…………………

 

The study of life

 

There are many branches of biology that scientists study because life is so diverse!

 

 

Properties of Life

1. CELLULAR ORGANIZATION

Living things are made up of units called cells

The basic structure of cells is the same in all organisms

Examples: People, plants, animals

 

2. HOMEOSTASIS

 Living things maintain a stable internal environment. A stable internal environment is needed or organisms to function.

 

3. METABOLISM

Living things obtain and use materials and energy.

Metabolism is the sum of all chemical reactions carried out in an organism.

 

4. RESPONSIVENESS

Living things respond to their external environment

Example: Plants bend toward sunlight

 

5. REPRODUCTION

Living things reproduce. Reproduction is when organism make more of their own kind from one generation to the next.

 

6. HEREDITY

Heredity is the passing of genetic traits from parent to offspring.

This explains why children look like their parents

 

7. GROWTH

All living things grow and develop

As organisms grow, they change. This is called development.
