Hello, my name is Brian the 

Brain and this is my dog 

Toby.We're here today to 

teach you some important 

scientific terms and how 

you can relate them to some 

cool experiments. 

Physical Change- changes affecting the form of a 

chemical substance, but not its chemical 

composition

Chemical Change- is any change that results in the 

formation of new chemical substances.

Chemical Property- a property or behavior of a 

substance when it undergoes a chemical change 

or reaction. 

Physical Property- The measurement of a physical 

property may change the arrangement of matter in a 

sample, but not the structure of its molecules. 

Ex. mass, density, color, boiling point, temperature, and volume.

Mixture- a substance made by mixing other 

substances together.

Density is the amount of matter in within a certain volume. 

 Density can be found by using the equation: 

  Mass/ Volume 

Qualitative-Deals with descriptions.Data can be observed but not measured.

Colors, textures, smells, tastes, appearance.

Quantitative- Deals with numbers. Data which can be measured.

Length, height, area, volume, weight, speed, time, temperature, humidity, 

sound levels, cost, members

Now that all that 

vocabulary is out of the 

way...

Let's get started!!!!!

Let's look at some examples of finding density.

Mass/ Volume

1) Mineral #1: Mass: 16.5g Volume: 10ml 

16.5g / 10ml= 1.65 g/ml

2) Mineral #2:   Mass: 14.5       Volume: 4ml

14.5g / 4ml= 3.625 g/ml

3)Electric Circut: 

  Mass: 13.5g        Volume: 2.5 x 1 x 1.375= 3.4375cm3 

13.5g x 3.4375cm3= 3.927 g/cm3

4) Square Magnet 

Mass: 100.5g  Volume: .875 x .875 x 1.875= 1.4355cm3

100.5g x 1.4355cm3= 70.01 g/cm3

5)Round Magnets:    Mass: 68g Volume: 14ml 

68g x 14ml= 4.857 g/ml

6)Block #1: Mass: 21.5g Volume: 24ml

21.5g x 24ml= 0.895 g/ml

7)Block #2: 

Mass: 15.5g Volume: 0.75 x 1.75 x   0.75= 0.98cm3

15.5g x 0.98cm3= 15.75 g/cm3

8)Block #3 

Mass: 70g        Volume: 3.125 x 0.875 x1.75= 4.785 cm3

70g x 4.785cm3= 14.629 g/cm3

Now that we've learned how to find density by 

using the equation.... 

Mass/ Volume

Now it's time to do some cool 

science experiments!!!

For our first 

experiment we'll 

need: 

safety goggles

zipper bags

baking soda 

vinegar

For this experiment, you will place in a zip-lock 

bag 1 teaspoon of baking soda into 3-oz of 

vinegar.
