Summary: This week we learned more about sound and we reviewed what we learned previously. This week we learned about how sound travels through the ear. When sound enters your ear it goes in through the outer ear and into the ear canal which leads to the eardrum. After it goes into the middle ear and into the inner ear. Lastly the sound goes to the cochlea which allows your brain to figure out what you’re hearing. What we reviewed is about how sound travels through gases, liquids, and solids. Sound travels through solids the fastest, then liquids, and lastly gases.
SP3: Planning and carrying out investigations
A major practice of scientists is planning and carrying out systematic investigations that require clarifying what counts as data and in experiments identifying variables.
Did you plan and carry out an investigation?
(Mostly when we do a investigation, lab, or experiment)
Yes we did another lab in class which helped us understand how sound looks while traveling to a solid, liquid, and gas.
