Practicals

=Introduction= This Wiki page is for Year 7 & 8 students to research certain practical activities that we will be completing at different stage over the year. Please ensure that you read and understand the activity and safety aspects of each activity. If you have further questions please discuss with your teacher prior to the practical session.

The following practicals have been supplied from Science Action 1, Bason et al 1988 CollinsDove North Blackburn Vic. Australia.

Activity 1.1 Fire
The first activity will be based on the discovery of fire. Before proceeding to the file 1.1 Fires, write in your book the three essential resources required for fire. This is called the Fire Triangle and if any one of these three resources is missing there will be no Fire.

Draw a triangle ( the size of at least one third of your page) in your exercise book and along each side write each resource required for fire.



1.3 Making a model dragster
The aim of this activity is to harvest energy and use it by transferring it from one kind to another.

Think of as many ways as you can that you could power a model car and write these in you book. Then click on the link and prepare yourself for this activity.



1.4 Sorting Animals
As part of classification in Biology animals are sorted into many different classes. This activity will introduce you to sorting animals. In your book write down a few reasons why sorting and naming animals might be helpful to those who study them and also to us as scientists. Secondly write down a very brief system that you could use to sort the following animals into appropriate groups: Dog, wild cat, Lion, Jaguar, Shark, Flathead Fish, Redback Spider, Horse, Asian Elephant, African Elephant, Octopus



1.5 Heating Substances
This activity is essential to complete prior to using the laboratory. Ensure that you focus not only on the safety of using gas and flame in the lab, but also on other safety measures. Note in your workbook where the First Aid kit is found in the lab, also where is the Fire Extinguisher found. Does the Fire extinguisher show a the needle in the green or red part of the dial?. Use the picture below to locate and name all the incorrect or unsafe activities in the picture. You need to find approximately 24.





Now with your table group write out a list of rules that you and the group feel appropriate for all students to adhere to whilst in the lab.
