This simulation software uses a constructivist approach. It allows students to learn and explore information on agriculture. It is a fun, colorful, and makes sounds on the links to engage kids on the site itself. There are plenty of areas that teach new things about agriculture. Teachers can also use it to create lessons, use pictures on the unit to show the students, have crafts/activities that go with the lesson, and much more! They upload new information often and new topics weekly. It is a great way to make agriculture more intriguing for those who may not be that interested. It can also be used for engineering because it talks about the machinery and chemicals used on plants as well!

This tutorial weebly offers many different topics for all subjects. I chose science because it is hard to find software that covers so much in science. Even though it is a weebly, it has so much to offer. It is mainly uses a constructivist strategy but also can be viewed as directed because some of the specific topics and they way the weebly teaches the information. It is very easy to pick topics and follow the games through the instructions. It is a great for students to use on their own too! (Idea: homework?)
