Scientific Method Song- enjoy!

Einsteins, today we will create our Science Notebooks and cover Scientific Method!

 

Tardigrades

7th & 8th Grade- Hope you are enjoying your summer!!! My summer has started off great. We still have several weeks left of summer, but I would like for you all to watch this video and do a little internet surfing about these amazing creatures!!!! Yes, I said creatures. They look almost unreal, right? Well, they are not! These are Tardigrades (commonly known as waterbears or moss piglets)and they are found all over Earth, even right here in San Antonio.
Here are some interesting facts about them. They can live in geochemically extreme conditions that would be detrimental to most life on Earth.  For example, tardigrades can withstand temperatures from just above absolute zero to well above the boiling point of water, as well as pressures greater than any found in the deepest ocean trenches, ionizing radiation — at doses hundreds of times higher than would kill a person and have lived through the vacuum of outer space. They can go without food or water for nearly 120 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce.
This year I would like a research paper and project done about these little guys. I have even found a few locations where we can find some of our own to check out under a microscope. Enjoy!

8th Grade- Please review the following video so you will be prepared to create an Experimental Design Chart over an experiment of your choice.

7 Grade Genetics- Here is an interactive Fruit Fly Lab you can review before we actually anesthetize our classroom flies.

Remember atoms are composed of subatomic particles.

1. How are atoms structured?

2. What are the locations, masses and electrical charges of the subatomic particles?

3. Where are valence electrons located?

Protons determine the Atom’s identity.

1. How is the identity of an electron determined?

　

2. What is the importance of protons?

　

3. Why are protons used to determine the identity of an element?

　

4. Draw the Bohr model for the following elements:

　Chlorine                                           Sodium                                                  Iron

       Cl                                                     Na                                                         Fe
　
　
　
　
　
　
　
The periodic table is arranged by atomic number and shows many trends.

1. What are some patterns (trends) found in the periodic table of elements?

2. How are elements on the periodic table organized?

Radiant energy from the Sun drives the process of photosynthesis.

1. Why does photosynthesis need light energy from the Sun to complete the process?

　

2. What happens when light (energy) from the Sun is used for the process of photosynthesis?

　

3. Why is photosynthesis necessary to sustain life on Earth?

　

4. Where does photosynthesis take place?

　

5. What is the formula for photosynthesis?

Energy flows through living systems and is passed from one trophic level to another. It is then returned to the environment through cycles.

1. How does energy transfer in living systems?

　

2. What happens to the energy in matter that is decaying or decomposing?

　

3. How is energy returned to the enviroment through biomass’?

　

4. Create an example of a food chain

　

　

　

　

　

　

　

　

5. Create an example of a trophic level pyramid.
