This video discusses the required practical activity from the biology specification which involves investigating the effects of different concentrations of sugar solutions on the mass of plant material. The video uses the definition of...

What research is being conducted currently? How does it work? If successful, how can it help society? What careers deal with science and water?<br/>
Properties Of Water, Part 5

Whether fish get thirsty depends on the fish you look at. Fish that live in freshwater have different physiology to deal with their environment than fish in salty seawater. These physiological differences dictate whether fish need to...

Explain the process of digestion of each food component. Describe how and where various components of food are absorbed.

Have you ever wondered how plants take up water from the soil? Water uptake in plants is quite complex and involves a process called osmosis. Osmosis makes the water from the soil move into the roots of the plant. But what drives the...

What are the unique properties of water? What are the freezing and boiling points of water? Properties Of Water, Part 2

Transpiration is the evaporation of water from the aerial parts of a plant (so the leaves and stems). By water evaporating out of these parts - mostly the leaves, a suction pressure is created which draws water up through the plant. This...

Functions of graphs can be shifted and reflected. In this 2 part video we will look at horizontal and vertical, reflections and translations. Translations shift the functions. For vertical transformations, the transformation is applied...

Why is desalinated water important? How can graphene help with desalination?<br/>
Properties Of Water, Part 4

In this video, we discuss osmotic pressure by working an example.

Plant Structure and Function Set: 1. This clip examines the stomata of leaves. It discusses their structure, how they work and the important role stomata play in regulating the exchange of gases and water between the plant and...

In addition to learning about the structure and characteristics of seeds and plants, this program takes viewers to different locations around the world world. They'll learn about the diversity of plants throughout the various land...

The video is about osmosis, a type of diffusion in which water molecules move from a dilute solution to a concentrated solution through a partially permeable membrane. The video explains what a partially permeable membrane is and how it...

What are the characteristics of water? Explain the water cycle?<br/>
Properties Of Water, Part 1

In the first part of this video we looked at diffusion to move gases and osmosis for the movement of water, from high concentration to low concentration down their concentration gradient. Active transport works in the opposite...

Osmosis Set: 2. This clip examines tonicity: the effect of various concentrations of solute molecules and plant cells.

In this video, we explore the basics of osmosis, solute-driven water movement. We also discuss the meaning of hypotonic, hypertonic, and isotonic solutions.

Over 2/3rds of the earth is covered in water, but only 2% of that water is pure. As clean drinking water becomes more scarce, you maybe wondering What happens if I drink seawater? Let's first examine how our bodies absorb water. You may...

Osmosis Set: 3. This clip looks at some of the ways osmosis affects the lives of plants and animals.

Osmosis Set: 1. This clip offers an overview of diffusion and osmosis.

Friendly and fun host, Max Orbit, asks questions about the world and searches for answers. This DVD series is designed to engage students while introducing scientific principles and concepts in a fun and entertaining way. In this program...
