Building an electromagnet

This online resource looks at electromagetism.

The resource gives instructions for a hands-on activity where students learn about electromagnets through designing their own to achieve a set goal.

The students begin with only minimal guidance, and after the basic concept is understood, are informed of the properties that affect the strength of that magnet. They conclude by designing their own electromagnets to complete the challenge of separating scrap steel from scrap aluminium for recycling, and then share their findings with the class.

Build an anemometer

This online resource gives details on how students can create their own anemometers—instruments for measuring wind speed.

The students can then see how an anemometer measures wind speed by taking measurements at various school locations. They can also learn about different types of anemometers, real-world applications for anemometers, and how wind speed information helps engineers decide where to place wind turbines.

Breathing cells - cellular respiration

This online resource shows how pH levels can be used to measure the respiration of cells.

In this activity, students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the colour change of the indicator. They then review the concepts of pH and respiration and extend their knowledge to measuring the effectiveness of bioremediation in the environment.

Blow-and-go parachute

This online resource gives instructions for a student activity which explores the concept of unbalanced forces through the creation of a model skydiver.

Students make a skydiver and parachute contraption to demonstrate how drag caused by air resistance slows the descent of skydivers as they travel back to Earth. Gravity pulls the skydiver toward the Earth, while the air trapped by the parachute provides an upward resisting force (drag) on the skydiver.

All caught up

In this online resource, students learn of the difficulties fishermen experience while trying to target individual species.

Commercial fishing nets often trap "unprofitable" animals in the process of catching target species. In this activity, students experience the difficulty that fishermen experience while trying to isolate a target species when a variety of sea animals are found in the area of interest.

Air—Is it really there?

This online resource helps develop an understanding of the properties of gases.

The resource details some simple experiments to help students develop an understanding of the properties of the mixture of gases they are most familiar with: the air around us.

By watching and performing these several simple experiments, students gain an understanding of the following properties of air: it has mass, it takes up space, it can move, it exerts pressure, it can do work.
