I can use Phet Simulations to help me learn about Science
You can play, observe and do some experiments with this app and you can also have some fun
while your playing.
Here is an example of an app in the Phet Simulator
Balloons and Static Electricity
When you rub the balloon to the sweater you will see the electrons stick to the balloon
AND
When you move the balloon to the wall the balloon will stick to the wall and the electrons in the wall will move away from the balloon because like charges repel and opposite charges attract.
The opposites attract and the same repels
There are also some other apps that can help you on understanding some other lessons about science in Phet Simulator
I can’t find any problems in this website the only problem that there could be are your internet connection or your adobe flash player. I found that some of the games can’t be played if your adobe flash player is not installed or outdated. You can connect to a better internet and update your adobe flash player so you can enjoy the games and you can understand the lesson without experiencing any internet interruptions. I wasn’t able to find any apps because I am only using a Chromebook and I can only use the one that is a website.
Hope it helps
