Year 8 STEM Extended Study

You have two pieces of extended study to complete over the Easter break:
1. Complete your lab right up for the Water Purification experiment. See the attached photo which tells you the sections you need to have completed.
In your discussion you must explain what you found after we evaporated the sea water before and after we distilled the water by boiling it in the conical flask and condensing it in the test tube. What was the difference in the amount of dissolved solids before and after? What was there a difference? What happened? What was the pH change? Why did this happen? After the distillation, do you think the water was potable? If so, why? If not, why? Was your hypothesis correct or incorrect? Was it specific enough?
Make sure that you use correct scientific language and key words in your write up. Your work should be of high quality and be detailed. If you need help, please email me in good time.

2. Follow the links on Google Classroom. Read the texts and watch the videos on Enzymes to prepare yourselves by building your background knowledge for our next experiment; Enzymes- Investigation into the effects of pH on enzyme action.

3. Email Mr Voltaire with your answers to the following questions: 1. What is an enzyme? 2. What is the function of enzymes? Give examples 3. What is the lock and key theory? 4. What can affect the function of enzymes?

Guns, Germs and Steel Final Product

Here are some of the final products…
