How would you define energy?

• the capacity to do work

• the ability to cause a change

• energy makes stuff happen

• all of the above

A particle is thrown upward with some kinetic energy. What happened to its kinetic energy at the highest point or height it reaches?

• Its kinetic energy is lost

• Its all kinetic energy is absorbed by the air

• Its kinetic energy is converted to potential energy

• Its kinetic energy has remained same

A variation on kinetic energy is mechanical energy, which is movement energy when something turns around a pivot like a bending arm, so in bending arm which class of lever apply?

• First class lever

• Second class lever

• Third class lever

• Fourth class lever

How does your body turn food into energy? Build a concept map from the given outline.

- Inside the body, food helps us get energy and also to grow and repair ;

- their digestive system breaks it down into small pieces. ;

- When a person eats food, ;

- Those small pieces are digested and absorbed by the body.

Choose the best order that show energy transfer for an ocean food chain: seal, plankton, shark, fish, sun.

• seal, plankton, shark, fish, sun

• sun, plankton, fish, seal, shark

What is photosynthesis?

• Photosynthesis is the process by which plants convert energy from the sun into a food source using carbon dioxide and water.

• Photosynthesis is the process by which plants are able to grow.

• Photosynthesis is the process by which plants gives us food.

The food we eat contains stored ___________.

As the bonds between the atoms in food loosen or break, a chemical reaction takes place, and new compounds are created. Fill in the blank.

• On the left

• In the middle

• On the right
