Simple Machines

Click on website below for a simple machines game.  Explore the house and tool shed to identify all the simple machines we use on a daily basis to make our work easier.  Be sure to read the information following your answer choice to learn more about each type of simple machine.

Motion and Design

Welcome to Fourth Quarter!  This quarter, our unit of study will be Motion and Design.  We will be exploring the motion of objects and the engineering process.  For some background knowledge on how things move, listen to this song on simple machines.  They are not explicitly taught in fifth grade curriculum, but I feel they are important in order to have a full understanding of motion.  Enjoy!

Reason for the Seasons


In class, we read about James and Sophia.  In North America, James was experiencing winter during the month of February.  In Australia, Sophia said it was summer in February.  How is this so?  Watch the video to understand the reason for the seasons.

Convection Current


Watch the video to see a convection current.  In this example, you will observe how hot and cold water move in the fish tank.  The water moves in the same manner as air.  Since warm air is less dense than cool air, warm air rises, leaving space for the cool air to sink and take it's place.  Convection currents happen as a result of uneven heating of the Earth's surface (when it is warm in one place and cooler in another location).
