Study the image below carefully. What can you infer from the information?

Living things need energy to carry out life processes
The sun is the primary source of energy for plants and animals
Plants make food from carbon dioxide and water
All living things need air, food and water to survive

Right on the money!

Hmm, I don't think so. 😔

Fossil fuels and batteries are two sources of potential energy. How are they different?

The chemical energy in fossil fuels is changed to electrical energy when burnt while that in batteries is changed to light energy only in a closed circuit
Fossil fuels are formed from the remains of dead plants and animals while batteries are man-made
Fossil fuels have chemical energy while batteries have electrical energy
The energy of fossil fuels can be destroyed while the energy in the batteries cannot

Perfect! 👊

Uh-oh. That was incorrect. 😔

Which of the following are examples that show a force that can change both the direction and speed of a moving object?

C only
A, B and C
A and C only
B and C only

Way to go!

Doh! 🤬

Beautiful! 👍

Doh! 🤬

Which statement is true?

When switch B is closed only, Bulb Z will light up
When switches B and C are closed, Bulbs Y and Z will light up
When switches A and B are closed, Bulbs W, X and Y will light up
When switch A is closed, Bulbs W and X will light up

Fantastic! 🥳

Doh! 🤬

What is the energy change that occurs when John throws a stone which then hits a glass window?

Kinetic energy --► Potential energy + Sound Energy + Heat Energy
Potential energy --► Sound Energy + Heat Energy
Kinetic energy --► Potential Energy --► Sound Energy + Heat Energy
Potential energy --► Kinetic Energy --► Sound Energy + Heat Energy

Fantastic! 🥳

Not quite.

The diagram below shows the length of the spring when different weights were hung from it. What is the original length of the spring most likely to be?

19 cm
4 cm
16 cm
5 cm
21 cm
12 cm

That's great!

Nope, sorry. 😢

The following diagram shows three wooden blocks, X, Y and Z, of the same base area but different heights. They are tilted slowly until the boxes fall in the direction as indicated by the arrows. The angles at which the tilted boxes topple over are marked as shown in the diagram. What can you conclude from the observations?

The wooden block of shorter height will topple more easily
The base area of the wooden block affects the angle at which it topples
The greater the height of the wooden block, the smaller the angle at which it topples
The greater the height of the wooden block, the bigger the angle at which it topples

Right on! 👊

That was incorrect.
