The tasks included in this booklet reinforce the key ideas and skills taught in the science classroom. This booklet can be used to support your learning and to provide you feedback that enables you to actively monitor and evaluate your own learning.

All learning activities completed throughout the year, including your revision booklet, contribute towards your grading in the Science course.

Instructions

Students:

You are expected to complete all revision tasks in this booklet by the end of the term. You are to write all of your answers in this booklet. The answers completed in this booklet should be your own work. You are to complete the 1 task allocated per week, ready to hand in the booklet by the end

of that week. It is your responsibility to make sure your parents CHECK and SIGN your homework at the

end of each week. You must then bring your revision booklet to school for your teacher to CHECK and SIGN at

the end of each week. This booklet is my responsibility. If I lose this booklet I will need to ask my teacher for a

copy to be email to my student email. I am then responsible for the printing of this booklet. Incompletion of revision tasks or a non-genuine attempt will result in you completing this

work during lunch supervision. Some of the skills in this booklet will be used in the half yearly and yearly examinations,

so you are helping yourself succeed by completing the booklet!

I have read the above information and am aware of what is required from me and the consequences of not completing my revision tasks.

Parents:

All learning activities contribute towards your child’s academic achievement. Tasks including this revision booklet are used as a regular part of the teaching and learning process to clarify your child’s understanding of concepts, to remedy their misconceptions, and to support their further learning and the development of deeper understanding.

You can assist by asking your child to show you the revision tasks for each week. When the 1 weekly tasks has been completed, please sign the bottom of the activity sheet

for that week. You child will ALWAYS have Science revision.

When ice turns into liquid water, it

undergoes a change in state.

more than waters.

Less dense objects like oil, float on water, as their density is

less than waters.

5. When measuring the temperature of the ice water, the bulb of the thermometer is held above the bottom of the container.This is because the thermometer's bulb:

A. must be surrounded by the ice and water must not touch the container or it will breakB. has to be held against the ice to measure its temperatureC. has to be raised so it can be used to stir the ice and water

Task: Desalination in the Laboratory

Read the passage below to answer Questions 1-7

Circle the correct answer for Questions 1-61. In the diagram, the piece of laboratory equipment labelled B is a:

EHS Year 7 Science Revision Booklet 2016 Term2 Page 7

Various governments have considered constructing desalination plants to convert sea water into fresh water. Desalination is a process that removes dissolved minerals (including salt) from sea water.

Some Year 8 students investigated a desalination process and decided to desalinate sea water in the laboratory. They set up the following apparatus.

The students wrote some statements in their science workbooks.

• The particles of salt cannot be seen in sea water.• As the sea water is heated, bubbles appear in the solution.• The water in C evaporates.• A white substance is left in the conical flask.• The white substance in the conical flask is salt, which is a

solute.• A clear liquid collects in the test tube.• The clear liquid in the test tube is pure water.• The water condenses in B.• The sea water can be desalinated by the process of

distillation.

A. flaskB. beakerC. test tubeD. measuring cylinder

2. The process of changing liquid water to water vapour is called:A. condensationB. evaporationC. sublimation

4. In the diagram, the piece of laboratory equipment that is used to spread the heat of the gas flame is the:

A. gauze matB. tripod standC. conical flaskD. Bunsen burner

5. The name of the physical process occurring at B is:A. condensationB. evaporationC. sublimation

6. In the sea water, the salt is called the:A. soluteB. solventC. solutionD. suspension

7. Sequence the observations below in the order the students would see them in their investigation.Place a number inside each box to show the order.

Liquid collects at B.

Bubbles appear in liquid C.

A white solid appears at C.

Tiny droplets of liquid appear in A.

Task: INVESTIGATING THE GROWTH OF SEEDS Read the passage below and answer Q 1-6

Daniel’s results are shown in the table below.

Circle the correct answer for Q1-5.1. Which variable in Daniel’s investigation did he purposely change?

EHS Year 7 Science Revision Booklet 2016 Term2 Page 10

Daniel designed an investigation to test this idea.

• He selected 24 seeds and divided them into six groups of four seeds.

• He did not put one group of four seeds into the microwave oven. He placed the

other groups into a microwave oven for different amounts of time.

• Then he placed all the seeds into a plastic tray on top of wet cotton wool.

• He placed the tray onto the window sill and made observations every day. He

made sure that the cotton wool stayed damp.

Daniel was investigating factors that affect the growth of seeds. He used the Internet and found out that beans grow better if the bean seeds are placed inside a microwave oven that is switched on for 10 seconds.

A. type of seedsB. amount of waterC. amount of growthD. time in microwave oven

2. Identify one trend shown by Daniel’s results.

A. Microwaving seeds for 10 seconds will kill them.B. Microwaving seeds for more than 10 seconds will increase their growth rate.C. Microwaving seeds up to 5 seconds will increase the amount of growth over 10 days.D. Microwaving seeds up to 5 seconds will decrease the amount of growth over 10 days.

3. To measure average growth, Daniel probably made measurements of the:

A. width of plant stemsB. length of plant stemsC. number of plant rootsD. number of plant leaves

4. Daniel did not place one group of seeds in the microwave oven because:

A. he did not have enough timeB. he was using the leftover seedsC. he needed to make sure he had enough seeds growingD. he wanted to see if the seeds grow without microwaving

5. Why did Daniel use four seeds in each group rather than just one?

A. To make the experiment safer.B. To make the experiment more reliable.C. To make the experiment more accurate.D. To make the experiment more fun.

6. Complete the Safety Risk Assessment Table for this experiment. (The first one has been done for you.)

What are the potential hazards?

What could be the consequences?

What is the likelihood of that occurring?

What methods can be used to reduce both the consequences and the likelihood?

Water spill Slip over, resulting in possible bruises or broken bones

moderate - Have paper towel available to wipe up spills
