8.B.1. Describe and cite evidence that heat can be transferred by conduction, convection and
Conduction : a pot is heated by the stove which then heats the water inside it. The direct transfer of
heat by substances touching.
Recognize and explain that energy can neither be created or destroyed; rather it changes
form or is transferred through the action of forces
Newton’s Law of conservation.When cooking we use the same energy in the beginning as in the end
8.A.2. Laws of Motion
8.B.1. Transfer of Heat
Recognize and explain how human activities can accelerate or magnify many naturally occurring changes.
Human interactions can change the different elements of the Earth such as the land. be We use
machines and technology to help cook our food instead of old ways. We use microwaves, electric can
openers , blenders, and etc.
Recognize and explain that fossils found in layers of sedimentary rock
provide evidence of changing life forms.
The fossils found in different levels of rock tells us how the species was back then and how it has
became more complex of the years.There’s a lot of diversity in the field such as the population and
the different foods and techniques.
Recognize and explain the effects of the tilt of the Earth’s axis.
The earth’s tilt causes seasons .Regular motion can be stirring a mix at a constant rate in the same
8.D.3. Effects of Tilt
8.B.2. Evidence of Change
8.B.1. Environmental Impact
Recognize and describe that evolutionary change in species over time occurs as a result of genetic
variation in organisms and environmental changes.
As environments change so does the ability of the animal to adapt to it. We use more of the animals
parts in recipes and foods than back then where we used pieces on the animals and throw the rest
Provide evidence to support the fact that common substances have the ability to change into
Reactants mix together chemically to form new substances.When cooking we use sauces and foods
that we can’t get back once we mix them. So the elements change into a new substance
