Nanotechnology What is nanotechnology? A short introduction to nanotechnology, and why you should care about it - from author of Films from the Future and ASU professor Andrew Maynard. The video dives into materials science and advanced materials, and looks at how designing and engineering substances from the atoms they're made of upward allows novel properties to be developed and used. It also looks at responsible innovation when it comes to grappling with the benefits as well as the health and environmental risks of nanoparticles and nanomaterials.

Introduction Why is it you wash your hands before you eating and after using the bathroom? How many times do you think you have you touched your face today? Is there anything on the table in front of you? Is there bacteria in front of you on the table??
Synopsis Children are getting sick on a regular basis even though we could prevent many of these incidents. They need to know what is around them and how to handle the things around them they cannot see.
Making Agar Dishes 15 minutes to set: On the bottom of the petri dish, draw a line dividing it in half and label the sides for each partner
Nanoparticles What are nanoparticles ? This science video explains about nanoparticles. You will find the answers for; what are nanoparticles? how small they are ? can we see nanoparticles by our naked eyes? what are the differences between bulk materials and nanomaterials? why different nanoparticles of the same material have different colors? what is melting point depression? Please subscribe to "Science YOUniversity" for more science videos.
Our Nanoparticles! Titanium Dioxide - Absorbs ultraviolet light Places you can find titanium dioxide: sunscreen, paper, makeup, food, plastics, and rubber. Zinc Oxide - Pain relief Places you will find zinc oxide: rubbers, plastics, ceramics, glass, cement, lubricants,paints, ointments, adhesives, sealants, pigment, food, batteries, ferrites, and bandages.
Acquiring your sample: 1. Flip petri dish over and draw a line cutting the dish into fourths and label each side with initials. 2. Students will use their swab to take a sample of one item in the classroom. Each partner will then streak their half the dish. 3. Divide the dish into quarters. Apply a pinch of titanium dioxide to one quarter. On the other side put zinc oxide. 4. Close the petri dish and apply parafilm to seal the dish. 5. Place dish in incubator.
Making Observations 1. Create a data table in your notebooks. 2. Record observations of your petri dish. 3. 4. - Observations should include color, shape, size, and any other interesting characteristics 5. Use the image to the right to assist with descriptions. 6. Compare your quarters with and without titanium dioxide/zinc oxide.
Discuss your Bacteria! 1. Compare your bacteria to your partners, including how are they alike, how are they different, and how the titanium dioxide affected their samples. 2. Find another pair oto share and discuss their results. 3. Complete the Exit Ticket! 4. Extension: Utilizing the internet discover what type of bacteria is on your petri dish along with what its purpose is.
