Science Bottle Rockets

For the last couple of days in science we have been making bottle rockets. First we got a bottle and painted it. We then cut out some wings to put on the side. We then used the hot glue gun to stick it to the side. Then the other day we took them outside and we tested them to see how well they flew. We had to put a little bit of water int he bottom and then we used a pump to build up pressure then when there was lots of it it would launch into the sky. Then yesterday we cut the bottles in half and then we turned them into plastic bottle planters. To make them we had to get some of the felt fabric and make sure it can touch the bottom of the bottle we then got some dirt and little stones and put them in there. Then we put the seeds into the dirt and then sat the top half of the bottle into the bottom so that when we put water into the bottom half the water will go up the fabric and water the seeds.

It has been about a week since we platted the radish seeds into the bottles. We took one out of each bottle to see if any of them had grown but none of them had changed. It is now about 3-4 weeks since we planted the radishes in the bottles and they have grown a little bit but there is not really any change. We are most likely going to wait another 1-2 weeks to see if there is any change.
