What is Science?

1. What is Science? Karen Chu, MS (Master of Science) Aka Mason’s Mom

2. What does a scientist look like? Anyone can be a scientist!

3. What do scientists do? ? They ask questions! They do experiments to find the answers!

4. How many different kinds of science are there? • Acoustics - science of sound • Aerodynamics - science of how air or gas move • Anthropology - study of human cultures • Astronomy - study of things in space • Biology - study of life • Botany - study of plants • Cardiology -study of the heart • Chemistry - study of properties of substances • Criminology - study of crime; criminals • Dendrology - study of trees • Ecology - study of environment • Entomology - study of insects • Garbology - study of garbage • Geology - study of earth's crust • Geography - study of surface of the earth • Graphology - study of handwriting • Herpetology - study of reptiles and amphibians • Horticulture - study of gardening • Kinesiology - study of human movement and posture • Limacology - study of slugs • Linguistics - study of language • Mathematics - study of magnitude, number, and forms • Meteorology - study of weather • Mycology - study of funguses • Oceanography - study of oceans • Otology - study of the ear • Palaeontology - study of fossils • Pharmacology - study of drugs • Physics - study of properties of matter and energy • Radiology study of X-rays and their medical applications • Sociology - study of society • Speleology - study and exploration of caves • Tidology - study of tides • Toxicology - study of poisons • Virology - study of viruses • Zoology - study of animals And many, many more!!

5. What kind of scientist am I? I am a clinical scientist.

6. How to conduct a science experiment Steps BIG Scientific Word 1. Ask a question! OBSERVATION 2. Think of a way to answer the question EXPERIMENT 3. Predict what will happen HYPOTHESIS 4. Conduct the experiment METHODS 5. Watch and write down what happens RESULTS 6. Decide if your hypothesis was right CONCLUSION or wrong and tell what you learned

7. Acids and Bases • Acid • A solution that has an excess of H+ ions. It comes from the Latin word acidus that means "sharp" or "sour" • Base • A solution that has an excess of OH- ions. Another word for base is alkali

8. Acids and Bases • Acids • Bases

9. How do you measure how acidic or basic something is? • pH scale - A measure of the number of H+ ions in a solution.

10. Today’s Experiment • OBSERVATION • EXPERIMENT • HYPOTHESIS • Is vinegar an acid or a base? Is baking soda solution an acid or a base? • Use Ph paper to measure whether vinegar or baking soda solution is acidic or basic • ?????

11. Today’s Experiment • METHODS • RESULTS • CONCLUSION • Take 2 pH strips from box • Dip the end of one strip in the vinegar solution • Dip the end of the other strip in the baking soda solution • Compare each strip to the pH scale Write down what the colors and numbers were on your strips for vinegar and baking soda solution. You can even draw a picture of what you see! Was your hypothesis right or wrong?

13. What did we learn today? • Anyone can be a scientist! • Even Mason’s mom!! • Scientists ask questions and do experiments to answer them! SCIENCE IS FUN!
