In this experiment, we used a potato, an orange and a lemon to try to light a led light bulb.

  • To produce electron flow, a complete will light the bulb.
  • To find out if electrons are flowing, you could use a volt meter to measure it.
  • Our light bulb had too high of a voltage, and our fruits/vegetables didn’t produce enough voltage.
  • To improve our results, we could use bigger vegetables/fruits or light bulbs with lower voltage levels.
  • In this experiment, the transition metals and the crocodile clips cause the electrons to flow.
  • If you were camping, or there was power outage or any situation where you were without electricity, you could use these foods are sources of electricity.
  • No, because this was discovered a while ago. There are not fruits/vegetables big enough to power a 60 watt light bulb let alone a city or a computer.20151113_092019                    20151113_092858

My classmate and I will be using a citric fruit (lemon or orange) for this experiment because we believe that due to the high levels of acidity in the fruit will result in a good conduction of electricity.

Reviewing the app:            Chemistry Lab: For Windows

 

How will this app help me in science?

This app takes you through the periodic table. It labels and gives a large amount of information about the element as well as various sources online.

What grade would find this app the most useful?

Anywhere from grade 8-12. Around the age from where you would use the periodic table.

How does the app work?

When you open the app, a periodic table will appear. To view a certain element, all you need to do is click on it. Scroll through the information and at the bottom there is a key that helps you identify the family. You can also browse through the families by themselves as opposed to viewing the rest of the elements at the same time.

Why should I get this app?

This app is very handy for study or learning about elements. The information is very useful and accessible. As opposed to doing research on each element, the information is all put in one simple place. It also organizes the elements by over 20 categories. Ex: Boiling point, period, family etc.

When would I use this app?

Most likely in chemistry. For studying, learning or researching.

How easy is the app to understand?

It is quite simple. You have a periodic table are large buttons indicating where to click to change something.

How does the app help you learn?

It gives you plenty of knowledge about the periodic table and shows you how the elements are organized. It gives you facts you would have had to spend time on the internet researching at your fingertips.

Here is a screenshot of the app.
