Solar System Project
![Picture](/uploads/2/3/4/3/23434724/9547085.jpeg)
This is my solar system project and we got to chose a planet to create. We chose Uranus and made this model comparing it to Earth, and then made a power point. I learned many things, like how Uranus is the 7th planet from the sun and there could not be life on Uranus. This project was interesting because we got to add art into it and because we used math also. It was just really fun how these subjects were incorporated. What planet would you have chosen and why? This connects to me because I now know how far we are from the sun and Uranus.
Planetary Explorer

This is our planetary explorer race car. We bought race cars, and had to try to get them up a hill, push a box, go through an obstacle and battle. Our car did not do so good compared to many others. It was an interesting way to tie in traveling on planets and definitely was fun. I learned about the different explorers in which traveled to planets and what they needed for protection. Would you have fun with this? This connects to me because I learned how only one explorer had been on the planet I did above.
Create A Lab
Statement of Problem:
In this lab we will be testing Newton’s three laws of motion. The first law states that the velocity of an object won’t change unless a force acts on it. An example of that would be if an object at rest, like a pencil, will stay at rest unless someone moves it or picks it up. The second law states that force equals mass times acceleration. An example of that would be if someone threw a rock with a big mass with the same force that they threw a rock with a small mass, the smaller rock will go farther. The third law is that for every action there is an equal and opposite reaction. An example would be if a rocket takes off with upward force there is an equal force going down pushing on the ground.
Hypothesis Newtons First Law:
If we throw Katie in a basket toss, then gravity will pull her down.
Hypothesis Newtons Second Law:
If we throw two people in a basket toss with the same force, then the smaller mass will go higher and come down slower.
Hypothesis Newtons Third Law:
If we all do a backhandspring, then the reaction force from the ground will push us back up.
Materials:
Action:
We threw Katie in a basket toss.
Result:
Gravity pulled her back down.
Newton’s Second Law Experiment
Action:
We threw Katie (the smaller mass) in a basket toss.
Result:
She was in the air for 1.26 seconds.
Action:
We threw Haylee (the heavier mass) in a basket toss.
Result:
She was in the air for 0.95 seconds.
Newton’s Third Law Experiment
Action:
We all did a backhandspring and jumped backwards and pushed on the ground.
Result:
We came back up when the force from the ground (reaction force) acted on us to make us stand up.
Conclusions
Newtons three laws in motion is what we tested for this lab. Newtons first law states that an object in motion will stay in motion unless acted upon, same with an object at rest. Newtons second law states that force=mass(acceleration). Newtons third law states that for every action there is an equal or opposite reaction. The problem was that we needed to prove these laws true. If we throw Katie in a basket toss, then gravity will pull her down. If we throw two people in a basket toss with the same force, then the smaller mass will go higher and come down slower. If we all do a backhandspring, then the reaction force from the ground will push us back up.
In the first experiment we threw Katie in the basket toss, she came down because of gravity. In the second experiment the smaller mass ended up going higher than the bigger mass when thrown with the same force. This is because the more mass you have, the less acceleration you will receive. In the third experiment we all came back up when the reaction force from the ground pushed us back up.This shows the equal but opposite reaction we had. All of our hypotheses were true, therefore we proved all of Newtons laws.

Octogirl

This is my octogirl, which we created in class. This is something I am proud of and it was really fun. I learned about gravity and balanced and unbalanced forces. This was interesting because we did something creative and used motion and thrusts to add science. What would you have drawn to show different forces? This connects to me because gravity is what keeps me on the ground and moving my body around shows different thrusts.
Atom Project
![Picture](/uploads/2/3/4/3/23434724/1401904002.png)
This is my carbon atom project in which I created a model of the actual atom. I found it interesting how we made an exact diagram of the atom and how we used the materials to get it like it is. I learned how to read the atomic number and how to find out the number of protons, neutrons and electrons. What materials would you use to create something like this? This connects to me because I use carbon daily, by breathing, "carbon dioxide" and also carbon is in most of the food we eat.
