In this science project you will create a beeswax wrap and compare it's physical properties, sustainable characteristics, and food storage capabilities to commonly used plastic wrap.

Dive into the world of consumers in the energy cycle, exploring how animals, including humans, derive their energy from plants and other animals. This video explains the process of digestion, metabolism, and the role of nutrients like...

Dive into the intricate world of ecosystems, where every element, from the smallest organism to the broadest landscapes, plays a crucial role in the circulation of matter and energy. This video unravels how producers, consumers,...

Explore how chemicals like chlorofluorocarbons (CFCs) impact the ozone layer, which acts as the Earth's natural sunscreen by absorbing harmful ultraviolet rays. Understand the environmental consequences of ozone depletion, including...

Dr. Forrester explains how all animals rely on producers, or plants, to provide a foundation for food chains and food webs.

An ecosystem is a complete community of living organisms and the nonliving materials of their surroundings. This includes plants, animals, microorganisms and their environment, such as soil, rocks, and minerals. An Ecosystem also...

Despite the extreme rarity of attacks on humans, Sharks have become perhaps the most widely feared animals on the planet. How did this happen? They're not naturally aggressive towards humans and kill fewer people each year than falling...

Now that we know about nutrient cycling, we are ready to look at food webs as a whole. These represent feeding relationships within a community.These relationships designate certain trophic levels, so let's learn about what these mean...

This video covers:

- The idea that trophic levels are just the different levels of a food
chain
- Trophic level 1 are called the
producers
- Trophic level 2 are primary consumers, trophic level 3 are called the...

This video covers:

- The idea that biomass is just the mass of living organ

- Pyramids of biomass show the amount of biomass at each trophic level of a
food chain
- Why the amount of biomass decreases as you...

For ecosystems to function they need energy; and we can see how this energy moves through ecosystems with food chains. We also explore how the populations of predators and prey vary over time with predator prey cycles.

Dr. Forester creates a water ecosystem and identifies the roles of consumer, producer, and decomposer in the water ecosystem.

“Food Webs” explains the movement of energy from producers to consumers to decomposers.

A video entitled “Ecosystems: What If Algae Were Removed from a Pond?” which examines algae as organisms and discusses how one small part of an ecosystem can play a big role.

This video explores five fun facts about wildlife conservation.

Where do plants and animals get their energy from? Explore food chains and see how energy is passed from the sun to plants and on to first, second and third order consumers.

This video explores five fun facts about food webs.

In this video, I teach you how to make inferences while you read. A lot of times, the author doesn't tell us directly what is happening so we have to make inferences. I teach a simple and easy process to help you understand what you are...

Food Fighter is the inspirational story of one woman who abandoned capitalism in favour of social activism. Ronni Kahn founded OzHarvest to wage war on food waste, and to expose an inconvenient truth: that four million tonnes of...

This video discusses the significant sources of pollution in our oceans, focusing on the impact of chemical waste and plastic pollution. It highlights the consequences of pollution on marine life, human health, and the environment. The...
