Appendix 1

Assessment

LO 1

TECHNOLOGICAL PROCESSES AND SKILLS

The learner will be able to apply technological processes and skills ethically and responsibly, using appropriate information and communication technologies.

We know this when the learner:

Investigates:

1.2 finds out about existing products relevant to a problem, need or opportunity, and identifies some design aspects (e.g. who it is for, what it looks like, what it is for, what it is made of);

  • performs, where appropriate, scientific investigations about concepts relevant to a problem, need or opportunity using science process skills:

1.3.1 planning investigations;

  • conducting investigations;

1.3.3 processing and interpreting data;

1.3.4 evaluating and communicating findings.

Makes:

1.7 outlines a plan that shows the steps for making, including drawings or sketches of main parts;

1.8 uses suitable tools and materials to make products by measuring out, cutting or separating, shaping or forming, joining or combining, and finishing the chosen material;

Evaluates:

1.10 evaluates, with assistance, the product according to the design brief and given specifications and constraints (e.g. people, purpose, environment), and suggests improvements and modifications if necessary;

1.11 evaluates the plan of action followed and suggests improvements and modifications if necessary;

Communicates:

  • produces labelled two-dimensional drawings enhanced with colour where appropriate.

LO 2

TECHNOLOGICAL KNOWLEDGE AND UNDERSTANDING

The learner will be able to understand and apply relevant technological knowledge ethically and responsibly.

We know this when the learner:

Systems and control:

  • demonstrates knowledge and understanding of how to use energy sources to power mechanical systems in order to make a product move in some way.

We know this when the learner:

3.1 recognises how products and technologies have been adapted from other times and cultures;

3.2 identifies possible positive and negative effects of scientific developments or technological products on the quality of people’s lives and/or the health environment.

Memorandum

(A)

1. A longer screwdriver provides a more efficient lever. The longer the lever, the bigger the force applied on the load.

2. The heavier person should sit as close to the fulcrum as possible so that the load will not be too heavy.

3. Yes. Little children love to do “horse riding” on an adult’s foot. The person’s leg rotates round a fulcrum (knee, hip) and this creates enough force to control the load.

Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 1 more than 3 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles is 113?
mariel Reply
Mark = x,. Don = 3x + 1 x + 3x + 1 = 113 4x = 112, x = 28 Mark = 28, Don = 85, 28 + 85 = 113

I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
