Not a instructional activity in the traditional sense, this is a collection of resources with which you can craft a instructional activity on metabolic processes. It includes an outline of topics, some brief discussion, and a large array...

Students apply the science of chemistry to soil and plant relationships. They define diffusion and indicate for which of these nutrient(s) would you expect diffusion to be the most important for movement to the plant root? Pupils...

Learners participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

The need for a respiratory system in humans versus being reliant on gas exchange structures is demonstrated. There are many details about the advantages and disadvantages of each mechanism.  Students are able to learn about the...

Explore structures within the realm of gas exchange in terrestrial and aquatic life.  The excellent, labelled diagrams and clear descriptions help your students view the different structures and adaptations that have...

In this chemiosmosis instructional activity, students trace the flow of protons and electrons through the thylakoid. Students also explain several key terms including in the reading passage provided.

Access vocabulary knowledge with this online exercise. For this activity, learners match words to their definitions by choosing a letter from the drop-down menu provided for each word. This series of vocabulary exercises focuses in...

In this active transport worksheet, students review the cellular process of active transport including the structures and functions of the cell organelles involved. This worksheet has 28 fill in the blank statements.

Pupils explore the characteristics of topographical maps. They examine the relationship of contour lines and vertical elevation. Students create a three-dimensional model of a landscape represented by a topographic contour map.

For this electron transport worksheet, students review the steps involved in the electron transport system and how the synthesis of ATP happens. This worksheet has 30 fill in the blank statements.

The constant motion of our oceans represents a vast and complicated system involving many different drivers. Sasha Wright explains the physics behind one of those drivers- the concentration gradient- and illustrates how our oceans are...
