Launch #2 Reflection

Launch 2 = Check! We made it, we had our second launch a few weeks ago and it went really well. Our rocket went 28.5 meters high our first launch and on our second launch it went 27.5 meters high. When we launched for the second time the rocket went a little lower, but it was okay. On our first launch the weather conditions were sunny and beautiful but launch 2 weather conditions were wet and windy. I think that the wind really affected the launch because most of the rockets went lower than they did on launch 1. After launch 1 we decided to change our nose cone because ours got damaged in launch 1. My  observation is that our goal was to launch higher than launch 1, but that did not work. We think the wind affected the launch because almost all the rockets went lower.

 

Blog Post #2

In class we are planting plants. This is week 2 .

 

Our controlled has grown very well. The tallest is 17cm and the shortest is 14cm. It has 16 flowers and no buds. The color is light green.

 

Our manipulated has not grown well at all. The tallest one is 4cm and the shortest one is ½ cm. It has 4 buds and the color is light green.

 

I think the controlled is perfect because we gave it everything it needs. And the manipulated came out like that because the rocks did not give the plant the water it needs so it did not grow.

 

 

Plant Blog Post 1

Our class is studying plants. We grew them in pods with 4 holes. I had 2 pods one was my manipulated which we would mess up and my other one was my controlled which had the perfect amount of everything. My group had a question, what will happen if we change the soil to rocks?My hypothesis was if I change the the soil to rocks than the root will not absorb the water because  since the rocks are so heavy the roots can’t go down all the way, and the water goes down to the bottom and normally the roots would suck up the water but the roots can’t go down.

 

Our control plant has everything it needs It has perfect water, light, air and food.

 

We manipulated the soil by changing it to rocks.

 

Controlled: On the first day they sprouted. The tallest was 2 cm and the smallest was ½ a cm. They were green and had 2 to 3 leaves per plant and had heart shaped leaves.

Manipulated: The tallest was 2 cm and the smallest was 1/2 cm. It had 2 leaves per plant and the leaves were heart shaped.

 

The controlled grew much better than the manipulated the manipulated grew down and the controlled grew very well and bloomed flowers but the manipulated does not have any buds or flowers.

 

I wonder how tall they will be!

 

 

 

Maglev Day One

A Maglev train is a train is a train that moves by the levitation of magnets.
My groups idea was to put 2 strip magnet on the track with the north side up. Then 5 discs magnets on the car with north side up.
Nothing worked on Friday. The thing that we we did wrong was we put disc magnets on the car and strip magnets on the track what we needed to do was have strip magnets on the car and the track.
Greta was such a good partner she listened to my ideas and had such good ideas. That was my maglev day one experience.

Technology is…

I think technology is something that was man/woman made that solves a problem.

Sticky notes are technology because instead  of taping or gluing something to the wall you can just SLAP it on the wall.

The problem sticky notes solves is when you tape something to the wall and try to take the tape of the tape can  rip some writing of and you won’t be able to read it . And when you glue something it might not come off.
