Welcome to the LeConte Science blog. This blog is to serve several purposes. First, to provide a means of communication and increase awareness with respect to 4th and 5th grade Science at LeConte.
Second to provide another vehicle for students to notebook and share knowledge gained.
In general, it is also intended to serve as an information resource, a means of communication, and an archive of student work.

Balloon Powered Boat How and fast can a balloon powered boat travel?
Materials wooden boat straw tub of water timer balloon rubber band drill Procedure 1. Drill a hole in the aft of the boar and stick the straw through the the hole. Use tape to make sure the straw won’t stick down the hole. Blow up a balloon and put the end over the straw. Use the rubber band to hold it on securely. Pinch the bottom of the balloon do air doesn’t come out. 2. Place the boat in the basin of water. Start the timer as you let go of the balloon. Stop the timer when the boat stops moving.
Hypothesis My hypothesis is that the boat will keep moving for a minute and 25 seconds.
Data/Observations The boat was in motion for:1 min. 11 sec. I observed after timing the boat I could steer the boat by changing the straws direction.
Conclusion I learned that the balloon did not have enough pressure to make the boat go very fast, but it still moved. It was in motion for 14 sec. shorter than I predicted.
