Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity,...

Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...

Students examine the process of photosynthesis; its products and reactants, and the sequence of the process. They diagram the light reactions, record observations of plants, and discuss how difficult it is to measure plant growth as it...

Learners support the law of conservation of matter with evidence. They discuss the changes observed from the burning of the candle, and the differences in mass which are observed when the same reaction is carried out in an open or...

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass...

Students examine how nuclear reactions differ from other chemical reactions they have studied. They add up atomic masses of both the product and reactant side of an example of uranium decomposition, demonstrating mass loss involved.
