The body systems of animals work together to keep them alive.

• Research the11 human body systems. Create a table with the system name and main functions of that system. (integumentary, muscular, skeletal, nervous, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive and digestive)

Name of System with organs Main functions of each system
Integumentary - skin, hair, nails, glands, nerves Acts as a barrier to protect the body from the outside world.

• Practice with your parents quizzing each other about each of the systems, organs or parts of that system, and the functions. Keep score to see who wins the “Human Body Knowledge Game”

• Research and write about limiting reactants in a balanced chemical equation.

• Investigate stoichiometry using the virtual lab experiment with ChemCollective. In your journal, write the conclusions to the experiment.

• Review stoichiometry using the ChemCollective and clicking on Resources.

Consider the energy that you are using to perform this task:

• trace the energy and all of its transformations all of the way back to the Sun

• create a chart that shows the energy’s journey from potential to kinetic

• write a summary, explaining the chart, and describe how the energy was ultimately conserved

Topics/Terms to research:

• Simple Harmonic Motion

• Period

• Frequency

Research and define the terms above. Complete the following activities:

Activities:

1. Describe how three of your household items exhibit simple harmonic motion.

2. Build a pendulum using string, fishing line or tennis shoe string and a heavy mass- a shoe will work :) If you have a ruler or tape measure, determine the length of your pendulum in meters. ( 1 inch =2.54 cm) If you do not have a measuring device the height of 1 standard toilet paper roll = 0.095 m. Use a toilet paper roll to estimate the length of your pendulum. Release your pendulum from rest at a small angle and allow it to swing for 10 oscillations while timing. Take the total time and divide by 10 to determine your period of oscillation. Using the simple harmonic motion equation:

And solve for g, the Earth’s gravitational acceleration. Were you close to 9.8 m/s2? What are the possible sources of error? Change the mass and make a prediction about your resulting time. Be sure to keep the length the same and repeat the experiment. How do your two results compare and why?

Respiratory System

• Find a video about the biology behind the corona Virus and how it affects the respiratory system and write an essay about your findings.

• Create a model of the respiratory system and identify and define each part.

• Research Respiratory diseases and discuss issues and ways to cure or cope with the disease.
