Week of February 18th

We had another great week of skits in the Stingray classroom!  The students were excited to tell the rest of the class about a pyramid tomb, how Romans prayed to the heads of dead men who were killed in battle, and the poisoning of a teacher who the Greeks felt lost a battle for them. 

 

 

 

 

 

 

 
We are also well on our way to being simple machine engineers.  The students are working in groups of 3 to build a set of simple machines that will achieve a task.  Here the students explain what they are doing.

Group 1: We are trying to have Nerds candies hit the heart target by using a pulley, levers, inclined planes, and a catapult. 

 

 

 

Group 2: The purpose of our simple machines is to deliver a piece of candy via an airplane which rolls into dominoes, hitting a book, which will fling the candy into a bucket. 

 

 

 

 
Group 3: The purpose of our simple machine project to to deliver candy from one point to another point where a person awaits.  We will accomplish our goal by the following series of steps:
1. Slice a clementine in half.
2. The clementine will fall into a series of books.
3. The books will fall into a train.
4. The train slides down the inclined plane, knocking a marble down a slope of tracks.
5. The marble falls into a cup.
6. The cup falls. 
 

 

 

 
Group 4: The purpose of our simple machine is to swing a piece of candy to a random location.  There are 6 steps to accomplish this mission.  One step is to knock down dominoes.
