Wasps

In Aotearoa New Zealand we have several types of wasp. We can identify them by looking carefully at their features.

 

German wasps:

• are yellow and black
• have black spots running down their back
• have black antennae (feelers).

Lupins

In some parts of New Zealand lupins are a weed. When they grow along rivers, lupins change the water flow and cause flooding and erosion. They alter the environment for native birds and plants that live and grow there.

Fact file Kākāpō are the only parrots in the world that can't fly. They have strong legs for climbing. They are nocturnal. They are the heaviest parrots in the world, reaching up to 4kg. Kākāpō have yellowish-green feathers. They live in forests, grasslands, and coastal areas. They eat very low-quality food. They have a musty, sweet smell. When kākāpō feel threatened, they freeze.

The kākāpō are an endangered bird. Before humans came to New Zealand, the only predators of the kākāpō were the eagle, harrier, and falcon. These large birds used sight to hunt for their prey.

 

Use the fact file to answer the following question.

Question

Rainwater runoff

When rain falls it either: soaks into the ground to become rainwater evaporates, or flows over the surface of the land. In some places the surface of the land is permeable and the water soaks through and goes into the groundwater. In other places the surface is impermeable and the water flows over the land into rivers, lakes, and the sea. This is called runoff or storm water.

14)  Which of the following surfaces do you think are permeable? (Choose as many as you like.)

• • gardens

  • bush areas

  • concrete paths

  • grassed areas

  • sand dunes

  • roads

Question

When rain falls it either:

• soaks into the ground to become rainwater
• evaporates, or
• flows over the surface of the land.

In some places the surface of the land is permeable and the water soaks through and goes into the groundwater.

 

In other places the surface is impermeable and the water flows over the land into rivers, lakes, and the sea. This is called runoff or storm water.

 

15) Where do you think there would be more runoff - in towns or rural (country) areas?

• • Town areas

  • Rural (country) areas

Explain your answer

Question Change answer

16)  Runoff can cause damage. Drag each reason to the box with the matching idea.

16)  Runoff can cause damage. Drag each reason to the box with the matching idea.

Waste-water seeps into the ground rather than flowing over the surface.

Allows runoff to be carried out to the sea rather than flowing over the surface.

Limits the amount of plastic carried to the sea by runoff.

Don't leave rubbish lying around.

Wash your car on the grass.

Keep storm water gutters free of leaves and debris.

Question

Dissolving sugar

Some students dissolved sugar in water at different temperatures. Each time, they measured the temperature of 100 mls of water, put 1 teaspoon of sugar in the water, and stirred until all the sugar was dissolved. Here is a graph of their results.

33)  What does the graph show?

• • Sugar dissolves more quickly in hot water than cold water.

  • Sugar needs to be left in water for a long time to dissolve.

  • The less sugar there is, the more quickly it dissolves.

  • Sugar dissolves more quickly in cold water than hot water.

Sam put some sugar and water in a jar. He weighed the jar of sugar and water straight away and again when the sugar had dissolved. Here are his results.

 

35)  Which statement is backed up by Sam's evidence?

• • The sugar has gone because you can’t see it in the water.

  • The sugar is still there because the water will taste sweet.

  • The sugar is still there because the jars are the same weight.

  • The sugar could be gone because there is no evidence it is there.

Question

Cooling drinks

Alice wanted to find out if some drinks cooled faster than others. She put 250 ml of  water, tea, coffee, and milk into 4 cups.   She heated each cup in the microwave for 90 seconds. Then she timed how long it was before she could put her finger in the liquid. From her investigation she decided that milk cooled more quickly than water, tea, or coffee.

36)  Maya said the results could not be trusted. Choose three reasons she might think this.

• • The amount of drink in each cup is different.

  • The cups are different shapes.

  • She didn't time the heating of the drinks carefully.

  • She didn't measure how hot each drink got.

  • She didn't measure the temperatures accurately.

  • She didn't time how long the drinks took to cool.
