Where do you think the items came from originally?
Do you think the items look the same today as they did a month ago?
What happened to the matter in each item over the past month?
Do you think the items will be the same forever? Why or why not?
What do all of the items in the bag have in common?
Do you notice any relationships between the items in the bags? They all...
What evidence do you have that the items were all once part of a living thing?
Another name for "nature's waste" is "organic remains." These are all organisms that are no longer living, or parts of organisms that are discarded, excreted, or no longer needed. What other examples of organic remains can you think of?
What would happen to each item from your bag if it were left outside? What might it look like in 6 months? What would cause it to change?
What would eventually happen to the waste MATTER in each type of organic remain?
Why isn't the earth just piled up with all the matter from nature's waste?
Why could all of the items in the mystery bags be classified as nature's waste?
Do you think that all living things generate waste? What makes you think that?
I think they came from trees and plants because there leafs and sticks.
No, because they are less healthy and are not as as green and they are not getting food.
It decayed and died because it wasn't getting any nutrients.
No, because they are decaying and turning black and becoming soil.
They all are from trees and plants and they will all eventually become soil for other plants.
The grass and the plants both use photosynthesis to get nutrients. All the things will become soil.
They all have energy and when they brake down other plants get nutrients from them.
Sticks, Dog hair, and animal manure.
It might start looking like soil and it would look like this because it has no nutrients and it is dead or dying.
The waste matter would start to turn into soil and nutrients for the other plants.
It sort of is piled up with natures waste in soil ( because soil is plant waste) but other plants that are still alive take up and use some of the decayed plants energy.
It can all be classified as natures waste because it is all something that was part of nature but eventually it was not needed so nature got rid of it.
All living things generate waste because nothing can keep everything and still be healthy. If we did humans would be thousands of pounds.
Right when I took of I felt a blast of excitement and I knew I was about to experience an out of this world adventure! I was really nervous, yet excited at. I was with the rest of my class and we all were saying our goodbyes to Earth. I felt sad because I knew I might not see Earth again, but also happy because I knew we we’re about to shape the future of mankind! At blast off it was nothing like i’ve seen before. The rocket was shaking like a roller coaster and I was in a state of panic and fear, but then it felt like an awesome roller coaster. Things were falling off the rocket as we left Earth and the rocket was getting even more shaky and more things were falling off it. Then once we left Earth’s atmosphere we went around the spaceship to explore. We had an awesome time in zero gravity. One of the really interesting things was that we slept with sleeping bags with velcro to keep it on the the wall and they were on the bottom of the spaceship, the sides of it, and even the top of it because there is no up down left or right in space so there is technically no ceilings, walls, and floors.
. Practically everywhere in the spaceship there was places for sleeping. All around the spaceship there we're feeling of nervousness and excitement. After the first day everyone got used to the rocket and space and everyone was a bit more used to space, but a few people were really freaking out like Léa and Sophia they were kinda crazy at first. I really liked to look at Earth and see how much smaller it got from my view after each of the hours. My favorite thing to do was float around and do things I could only do in space. Everybody did trick competitions doing quadruple back flips and other thing in zero gravity. It was cool to watch, but even cooler to do! I played with my putty and spinners all the time and watched TV on my computer when I was bored. We ate foods that are kind of strange, but really interesting to try. In space we played cards with no gravity and just let our cards float around and we played war, but instead of picking random card each person started touching a wall and then flew in looking for the best cards, and then after they finished with their cards they would mix them all up again. It was really hard because all the cards where going in every direction and you really just had to randomly grab a card (if you even could!) and see if it was a good card. At the end of the third day we all compared how big the earth looked when we took off, to how big it looked right then. At the end of each day we celebrated our small success and played games and had lots of fun until we all got to tired, and went to sleep. We saw all kinds of really cool and interesting things. We got to see constellations from a much closer and better angle, and we saw the space stations that have been there for many years. We even said hi to the people in the space stations! We video chatted with our families and we told them all about our experiences and showed them tricks in zero gravity. We saw the sun from the spaceship and it looked much smaller because we were going away from it. We could see other planets and their moons and thing no naked human eye has ever seen before! It was weird to think that anywhere and everywhere we went we were the first! Then in the fourth day a big part of the rocket fell of and I was really scared until I learned that we only needed that part for take off on Earth. We looked through telescopes in the spaceship and saw a really clear view of Mars. We started looking at lots of nearby stars and mapping and studying them so we could send that new information to Nasa. We observed lots of stars just for fun as well. Then on the sixth day we saw an asteroid field about 10 mile away and got scared but then we calculated the velocities of all the asteroids but then learned that we were safe. During the sixth day I felt really sad and homesick because I haven’t seen my family in real life in a somewhat long time, and I knew I could possibly never truly see them again. Then at the end of the seventh day we had a big party and that reminded me what our trip to Mars was all about: Making Mars better for the future, having fun exploring, and colonizing Mars. Then I video chatted with my family again and then went to bed feeling happy and proud that I survived a week in space!
What do you know about NASA's plans to visit Mars?
How long will the trip take?
What supplies and equipment will the astronauts need to survive there?
What do you think are the risks of traveling to such a distant planet?
What would you want to bring with you?
They plan to use plants to get oxegen. They are tring to use the least energy and make the plants grow as best as possible using waste. They also have made a machine that turns urine into drinking water.They plan to use centrifical force to make gravity to keep the astronuats healthy.
The trip will take about 6 months.
They will need a source of oxegen, food and a way home. They need to be able to have all there basic needs.
You might run out of oxegen and you might run out of food. You can also have bone and muscle loss when in zero gravity.
I would bring food water and plants (for oxegen) and things for me to do.
