5 Basic Steps on How Humans Hear

1.Sound waves travel through the air, reach the pinna and are funneled down to the ear drum.
2. Sound waves hit the eardrum and cause it to vibrate

3. The vibrations continue through the three tiny bones in your middle ear (the ossicles).

4.The vibrations continue through the three tiny bones in your middle ear (the ossicles) to the cochlea.

5. These hair cells turn vibrations into electrical signals that are sent to the brain, and the brain interprets the source of the sound (piano vs. a guitar).

Design Challenge Expectations

“Providing students a foundation in engineering design allows them to better engage in and aspire to solve the major societal and environmental challenges they will face in the decades ahead!” (nextgenerationscience.org)   

UAS middle school students will be using their critical thinking, team building, communication, design and engineering skills to create musical instruments out of recycled material.

After creating and improving their instruments, each small group of students will perform a song about science.

It is essential for each student to participate in the design and creation process.  If performing during Ramadan is in conflict with your family’s religious beliefs please let your science teacher know.  We will be happy to make accommodations for the performance aspect of this assignment.

Parents, you can support your child by reminding them to bring in materials and assist them in researching how various instruments work.  You are welcome to join us for the middle school assembly on the morning of the 18th to celebrate the process students went through to achieve their instrument creations.

Please note students will be using various tools to build their instruments.  Students need to follow all directions and procedures when using the equipment.  If a child can not use the tools responsibly, they will lose the privilege of using them.  For the safety of themselves and their classmates, students who are not responsible when using the tools will no longer be able to use them.  These students will need to write a paper instead of creating an instrument.

Thank you for your support and understanding.

We are looking forward to an engaging and innovative end to the year.

Study Tips for the Upcoming Exam

If I was a sixth grade science student this is how I would study for this exam:


Review the vocabulary in your science notebook.  These terms will be fill in the blank – with NO word bank


Watch the Bill Nye video – pay attention to atoms and molecules comparison


Look at the link about how water molecules work


Review your atoms family paper

  • You may be asked to label the atom including the proton, neutron, electron, nucleus and energy level


Know the difference between mass and weight

  • Be able to give specific examples


Review the information on the previously posted study guide

Quiz Next Wednesday and Thursday

Quiz Study Guide


You will need to know the definition of:

  • Mass
  • Matter
  • Weight
  • Atoms
  • Molecules


Accurately draw and label a water molecule and an ammonia molecule

*points will be deducted if it is not drawn to scale

*you will need to know their chemical formula


Explain how water molecules work
