You seed should be growing.

Please transfer the seed to a pot and start collecting data.

At this point in time, you need to keep your watering to just twice a week. Keep a record of this.

Look at new features of your plant and start to make quantitative and qualitative observations.

Begin to decide how to experiment with your plant (see ideas below)

Number One

Sheet Number 19 and 20

What makes a hypothesis?

Note not just a guess but a testable prediction

A formal hypothesis must include “If” and “then”

A hypothesis should be a testable idea.

“If” is the independent variable

“then” is the dependent variable

When graphing data that evolves from this hypothesis, the independent variable is the Y axis and the dependent variable .

For example :

If plant x is given nutrient then it will grow.

Data for this experiment would be a measurement of height (on the y axis) and the time you made the measurement would be on the x axis. Now you would a graph that could show change of length of stem, leaf or even width of stem and link that to time.

activities of life

https://courses.lumenlearning.com/boundless-biology/chapter/themes-and-concepts-of-biology/

From our first look at the history of biology, you will note that living things were often classified by their observable structures, like feather or leaves. Prior to more information on atoms and biomolecules, classifying living things was easier.

Yes what happens when you focus on a specific level of organization? Now you have more properties to compare.

As a hypothesis ..if you see similar traits then that organism may be related to the other..and this is the challenge of taxonomy.

In chapter 7 and in you timeline, notice how biology changes from no classification to the ideas of Linneaus.

What happens when we introducte metabolism?

Realize that all activities of life are linked to this one specific activity of life.

Also realize that proteins help regulate all living things to maintain some sense of “balance” or homeostasis.

So how are living things related not only by their shape but also their bio chemistry

Number Two

Seed experiment.

If you give a seed water, then it will grow

Yet, we have noticed that other life grows too. To compare results, we need to make sure that all procedures are the same.

Type of seeds need to be greater than 20 to insure more data.

We need to make sure that each plant is the same species. Why?

What is the independent variable in this experiment.

How are you going to graph the data?

Now ..phase two..what if we gave a growing seed a chemical to help it grow, how could we design an experiment?

Number Three

Lets suppose that living things can be related to their genetic material and proteins.

Biological Molecules ( chapter one)

https://www.youtube.com/watch?v=H8WJ2KENlK0

In all living things are structures call proteins.

Proteins are made of amino acids.

Amino acids can be grouped in a specific order.

You can estimate how similar proteins are by:

Calculating the percentage of each amino acid

Calculating the similarity in order of amino acids.

This is the foundation of case study

You home work is to read and begin the case study.

Important points:

The similarities of amino acids and proteins is a measurement of “degree of relativeness”.

Just because you have a similar protein as a moth does no mean you are directly related to that moth.

Protein makes structures. The study of structures in living things can be linked to “morphology”. For example if we look at the shape of different types of beaks in birds, we may get a clue as to designing a family tree.
