2017-18 Project
This energy project had students creating super-posters designed to bring together many components of the development of a new technology. Each one needed a visual component and a description. Teams worked in groups of two, but teams of eight to create a large, tiled poster that had to be cohesive across all groups. Example posters can be seen below.
Audience: High Tech High International and High Tech High Chula Vista 10th grade chemistry students. Requirements: Each pair was required to create a 24"x36" poster (cohesive among the entire group). |
POWER SOURCES:
Fossil fuels, lithium ion batteries, water power (dams/hydrothermal/wave), wind, solar, nuclear. Each poster must contain for each category:
Chemistry Societal Impact Financial Cost Environmental Impact Categories included: Extraction/creation, transportation, manufacturing, distribution, safety, maintenance, range of applications, waste/recycling management. |

Hydrogen Bonding Lab
Station 1: Drops on a penny
See how many drops of water you can get on a single penny before it spills! Record your observations and number of drops.
Station 2: Drops on a penny
See how many drops of denatured alcohol you can get on a single penny before it spills. Make sure the fume hood is on and you are wearing safety goggles. Record your observations and the number of drops.
Station 3: Paper clip and pepper on water.
See if you can get a paperclip to float on the water in one of the larger beakers. Metal is much more dense than water. Why does the paperclip float?
Fill a petri dish about halfway up with water. Put some pepper on the water. Write down your observations. Pepper is also much more dense than water. Now place a drop of soap on the surface of the water. What happened?
Station 4: Why do we need dish soap?
Rub some oil on the inside of the lid of the petri dish. Place a single drop of water on the oil. Describe the shape of the water drop. Now place a single drop of soap on the water drop. What happened? Record your observations.
Station 5: Electric charge and water
Rub the balloons on your hair to create a static charge. Start the sink and let a very small steady stream of water come down. Hold the balloon near the water and observe what happens. Record your observations here. Test what happens when you rub a sock on the balloon. Test what happens when you rub the plastic tubes on your hair.
Station 6: Capillary action
Take one of the small tubes and touch the end without the black line to the surface of the water. Do not submerge it. Watch what happens. Measure the amount of water that entered the tube. Record your observations here.
Now that you have experienced many demonstrations of hydrogen bonding, what are some uses for this in everyday life?
- What were the metals involved in your battery?
- If your LED requires 1.5 volts to light up, how many volts did each cell of your battery provide? (A cell is defined as a group of penny, zinc washer, and cardboard).
- How is energy being converted to electricity in this battery?
- What is a voltaic pile? How is it related to the battery you just built?
- What is an electrolyte?
- How did you know which end of the battery was positive, and which end was negative? (let’s refer to the end with the foil as the bottom)
- Determine at least two other potential uses for your battery other than lighting an LED. What else could your battery power?
