Answer:
Because students were taught through the use of demonstrations, they were able to successfully conduct their own science experiments,
Explanation:
This is the likely answer to the question on What cause and effect relationship is described in the article.
Answer:
Salt is the variables being tested.
Explanation:
Solubility of salts are the variables being tested in the experiment by changing temperature. Variables are those factors or elements whose values are changing. Salts are put in the two test tube which has the same temperature i. e. 25°C. Then the temperature of the test tube will be increases and due to increase in temperature, the solubility of salts in water increases and the whole solution will be uniform while salts remain at the bottom due to no increase in temperature.
Answer:
thermal energy
Explanation:
because that is how chemical reaction is formed
4. All of the Above. A good summary should have details.
