## Young Architects

This year I am offering a new Nurture Learning course called Young Architects.

Previously I have shied away from the Technology part of the NSW syllabus, but last year I trialed this course with my own children, plus doing a few extra excursions with an architect friend of mine. The course and the excursions were a big hit and so I decided to offer the course to homeschooling children in the Sydney area.

It’s a shorter course than I usually offer: just six one-hour classes plus two optional two-hour excursions. The classes will largely be delivered by walking around areas of the Northern Beaches. In this way we can look at the purpose of different buildings and spaces, how purpose informs design, how people interact in spaces, systems in the built environment, how buildings have changed over time and how they might change in the future. We will finish off by doing a site survey in the local area and then the children can build models of their ideas for that site.

Following from the success of the Young Scientists course I am really excited to share this new course with my regular students and see what wonderful ideas they come up with. I hope that some new children come along too.

## Forces and Motion

We had two classes this term on Forces and Motion. These were fun classes, largely outdoors, and we went beyond what is expected in the NSW syllabus or the Australian Curriculum. The classes varied due to the different student groups, and the weather, but we all managed to think about:

Gravity . In one class this included a discussion about acceleration due to gravity being lower on the moon;

Inertia and Newton’s First Law of Motion (the children brought their skateboards and scooters to the playground and thought about how they needed to exert a force in order to start off motion).

Newton’s Second Law of Motion (often expressed as F=ma where F is the force, m the mass and a the acceleration). In one class this worked well. We had a heavy child and a lighter child each on scooters and another child pushed them with roughly the same force each time. The heavier child travelled a shorter distance. Hooray! In the other class this didn’t work out so well and I was left trying to think of a better way to illustrate Newton’s Second Law.

Newton’s Third Law (Action and reaction). The demonstrations of this included using your foot to push off when you ride a scooter, balloon cars, and two toy cars crashing into each other so that they rebound. The balloon cars we used were commercial ones, but you can make some with Lego and everyday objects following the instructions here.

We looked at a BBC worksheet(pdf) about balanced and unbalanced forces, including the forces on a plane while in flight.

In one class the rain was tipping down outside and so we stayed in the sports hall to talk about magnetism and then I asked the children to demonstrate all three of Newton’s Laws using either a marble run or toy cars and a HotWheels track.

In the other class we were outside for some of the time and used playground equipment to demonstrate simple machines. Hauling a heavy bag up a slide is a good example of how an inclined plane can be used to lessen the force needed.
