Newtons Laws and Mechanical motions

I learned a lot about Newtons laws.
I learned that Newtons first law of motion says "An object in motion stays in  motion unless acted upon another object

I also learned that the second law of motion says "an object will accelerate in the direction of the net force, like what we did in class this week

The next thing i learned is about newtons 3rd law that says for every action, there is an equal and opposite reaction.

All of these Laws are used in the daily lives of every single person in the world.



Proving Newton's Second Law

Question: How does mass and acceleration relate to force

 



Materials used:

• wood track
• spring scale
• weights
• car

Hypothesis: The larger the mass on the car the more force it takes to move it

Steps:
1) Get supplies, stop watch, weights, spring scale, car, and wood track
2) Go over to the station you will be preforming experiment in
3) Put the wood track flat then put a weight in the car, then pull the car with a spring scale to record its force
4)Preform experiment when track and everything is set up
5) After that raise the wood track, angling track at desired angle
6)Record data throughout experiment
7)get graph paper
8) on the X-axis put force (N) on Y-axis put acceleration
9) Plot data, use a line graph
10) Get another piece of graph paper
11) On X- axis put acceleration (m/s2) on the Y-axis put mass (G)
12)Using a line graph plot the data

Museam Of Science Field trip

Audiokinetic Sculpture:

The AudioKinetic Sculpture was very interesting. When I was watching this huge sculpture I was amazed because it must of taken a lot of planning and trial and error to make. I noticed that when watching this one action moved to another, it was very interesting. Although it was cool to watch it was hard to look at because it was so tall. it was a little hard to see because it hurt your neck trying to look up and follow the ball.

Fantastic Forces:

The Fantastic Forces was cool. This presentation was a little awkward because the lady was trying to be funny, but she wasn't. Also she was seeming to kind of being over the top with her attitude or emotions. But, the presentation was cool, it was interesting to see how the balls transmitted force to each other. Also it was cool to see how she didn't get hit in the face with the ball, also it was cool when she pulled the table cloth out from under the water.

Engineering Design: Bobsled

This was really fun to do. I thought it was fun to try and beat the record for the day and try to improve how your Bobsled works. Also it was fun to go against other people to try and beat them and make your Bobsled the Best. Also it was cool watching how something's worked and some did not and how other people were thinking.

 

Lightning Show:

The lightning show was the coolest thing we did all day. It was cool when the guy made the lightning make a song, I did not know that lightning could make sound. also it was cool how that little girls hair stood up because of static electricity. When the guy was in that cage I cant believe he did not get electrocuted.

Ice Melt Lab

Ice Melt Lab:
Initial Temp
5c

8c

10c
12.5c   Ice gone

40c

50c
60c

70c

73c

80c

87c Simmer
93c
95c   Light Boil
95.5c   After 1 mins of boil

1) The water cools down because the ice melts changing it to a liquid and the liquid evaporates
2) the ice absorbs heat because when the ice melts it absorbs heat

Chemistry Of Life

1) How does protein that we eat get to the rest our body? when we digest Amino Acids the energy and extra parts that is made used to break the amino acids apart is used to form proteins. Then the blood transports the proteins to the rest of the body

 

2) How does a bowl of pasta? in a bowl of pasta there are carbohydrates. Carbohydrates are used to supply energy to the cell for cell activities.

 

3) why do we need fats? We need fats because we need Phospho Lipid Bilayer which are present in all fats. we need this because it protects the middle of the cell and it helps with homeostasis.  

Five Chemical Reactions

The five chemical reactions are

• Synthesis- is when two or more substances combine to form another more complicated substance 
• Decomposition- Opposite of synthesis, One substance breaks down into two or more simpler substances
• Single Displacement- Occurs when one element replaces another element in a compound
• Double Displacement- Two different atoms in two different compounds exchange places
• Combustion- A hydrocarbon reacts with oxygen, the products of combustion are always water + carbon dioxide 

Synthesis- when we lit the steel wool on fire
Fe+O2+-->Fe2+ O3

Displacement- nail in copper sulfate
Fe+CuSo4--> Cu + Fe2(So4)3

Trends in the Periodic Table

This week in class we talked and learned about the Periodic Table. The Periodic Table is organised by the type of metals. The most metallic metals are on the far right side, while the least metallic metals (gases) are to the far left. the middle group is called transition metals. A period is the metals going horizontal on the periodic table, a group is the metals going vertical. Electron Affinity sets a trend because the atoms above it are always larger. The trend of ionization energy is when the atomic number rapidly increases.
