In my personal opinion, all we have learned is this transdisciplinary theme. So, I will do a summary of all we did :
1. Types of energy: There are different types of energy for example:
- Chemical energy.
-Heat energy.
-Physical energy.
-Gravitational energy.
- Kinetic energy.
-Sound energy.
-Electrical energy.
-Light energy.
-Elastic potential energy.
2. Sources of energy: There are two types of sources of energy. Renewable and Non-renewable.
3. Knowing the difference between a simple, and a compound machine:
a) Simple machines: These are the fundamental ones, for example, a crowbar, the lever, a scissor, a pulley, a screw, a ramp, wedges, a knife, an axe, chisels, a hammer, and the wheel an axle, and more.
b)Compound machines: Two or more simple machines make a compound machine. For example, a stapler, a wheelbarrow, a hand drill, a can opener, and more.
4. Physical and chemical changes:
A physical change is something that changes but it has the same identity. For example, when you make origami your paper is still a paper. It changes but it has the same identity.
A chemical change is when something changes and it changes its identity. For example, when an orange rots, the orange has a new identity because it would never be the same.
