What is Science?

What does a scientist look like?

Anyone can be a scientist!

What do scientists do?

?They ask questions!

They do experiments to find the answers!

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!!

What kind of scientist am I?

I am a clinical scientist.

How to conduct a science experiment

Steps

1. Ask a question! OBSERVATION

2. Think of a way to answer the question EXPERIMENT3. 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

BIG Scientific Word

Acids and Bases

• Acido A solution that has an excess of H+ ions. It comes from the

Latin word acidus that means "sharp" or "sour"

• Baseo A solution that has an excess of OH- ions. Another word for

base is alkali

Acids and Bases

• Acids

• Bases

How do you measure how acidic or basic something is?

• pH scale - A measure of the number of H+ ions in a

solution.

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

• ?????

Today’s Experiment

• METHODS

• RESULTS

• CONCLUSION

1. Take 2 pH strips from box2. Dip the end of one strip in the

vinegar solution3. Dip the end of the other strip

in the baking soda solution4. 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?

What did we learn today?

• Anyone can be a scientist!

o Even Mason’s mom!!

• Scientists ask questions and do experiments to

answer them!
