What is static electricity? What is human-harnessed electricity?
Static electricity is when electric charge builds up on something, like when you rub a balloon on your hair. Human-harnessed electricity is the kind we use in homes and buildings, coming from power plants and wires.

What is a microorganism?
A microorganism is a tiny living organism that can only be seen under a microscope. Examples include bacteria, fungi, protozoa, and viruses.

Question: How are static electricity and human-harnessed electricity different?
Static electricity happens when electrons build up and make a sudden spark. Human-harnessed electricity flows in a steady way through wires to power things like lights and TVs.

Compare beneficial and harmful microorganisms.
Beneficial microorganisms help with processes like digestion, food production, and decomposition. Harmful microorganisms can cause diseases and spoil food. For example, E. coli can be harmful, while Lactobacillus is beneficial.

imagine you are designing a new way to use electricity. Would you use static or human-harnessed electricity? Why?
I would use human-harnessed electricity because it is more reliable and can power machines for a long time. Static electricity cannot provide steady energy, so it would not be good for running appliances.

Design an investigation or multimedia presentation that presents an argument, supported by scientific evidence, showing how microorganisms can be used in environmental cleanup efforts (e.g., oil spill bioremediation).
Sample project idea] Students could create a video presentation explaining how certain bacteria, like Pseudomonas putida, are used to break down oil in marine environments. The presentation would include data from case studies (e.g., the Deepwater Horizon spill) and interviews or quotes from environmental scientists, showing how these microbes reduce pollution and support ecosystem recovery.

How do people use static electricity in real life? How do people use human-harnessed electricity?
Static electricity is used in printers and air purifiers. People use human-harnessed electricity to power homes, businesses, and technology like computers and phones.

sing at least two pieces of scientific evidence, construct an argument that supports the claim that some microorganisms are beneficial to human health.
