This is an android app, there is a free trial but then you do have to pay about $3 for the rest of the experiments. The app opens with an experiment using batteries, tape, paper, two alligator clips, and a pencil led. The isea is to build a simple circuit. The whole experiment is guided on what ever device you use. After the experiment is conducted it is even explained. The guide even tells you why pencil led was used, graphite contains carbon and carbon can carry electricity. I would use this app in a young classroom to introduce electricity, or the flow of energy. I might even use this as an opener so everyone can do it. Then we might discuss what exactly we learned, or what else we would like to know. I would also set up at least one real experiment to show the students up close. I wouldn't let them do a real one on their own unless they were 3rd grade and up. I think this is an amassing way to introduce electricity and show students how circuits work. Electricity is a real world thing that they use every day.

Composting is the oldest form of recycling. It provides an opportunity for students to observe the decomposition process and energy cycle at work; produces a valuable soil supplement; and reduces the amount of organic material requiring a landfill or incineration. This is a neat hands on lesson that can last up to the whole year! The students get to understand the process of composting and will learn that there we can use other methods of eliminating our trash. My favorite part is that they get to physically see what is happening in the soil. I would start this activity towards the beginning of the year. The students can volunteer to bring in items from the materials list to help feel involved in the prep. I would have the students keep a journal about the chances they see when we check on the compost bin.

SC.E.1.2.3 Students know that our Sun is a star and that the energy of the Sun can be captured as a source of heat and light on Earth (e.g. plants, solar panels) Students will have a basic understanding of the vocabulary words sun, solar system, star, planet, asteroid, comet, orbit, axis.
