Scientific Method
When heat is added to a solid, will the atoms move faster or slower?
Faster
Matter cannot be created or destroyed.
The Law of Conservation of Mass
You need 10 grams of iron to react with 5 grams of oxygen to produce how much iron oxide?
15 grams
What can you use to record your data and observations?
A science notebook or computer
What is the last step of the scientific method?
Conclusion
What state of matter do atoms move around the fastest and have the most space between each other?
Gas
When matter changes, its a physical or chemical change. Can I get rid of matter completely?
No
The atoms in this state of matter spread out and fill their container.
Gas
What step of the scientific method comes after the experiment?
Analyzing data
What state of matter do atoms vibrate and have the least amount of space between each other? They are also organized.
Solid
What does the Law of Conservation of Mass state?
Matter cannot be created nor destroyed, only changed.
I have 3 grams of water, 6 grams of flour, and 9 grams of lemonade mix. I combine the water and the lemonade mix together. How many grams of lemonade do I now have?
12 grams
If I melt something, is that a physical or chemical change?
Physical
What do you do if your data from your experiment doesn't support your hypothesis?
Restart your experiment after making some changes.
Because the atoms in this state of matter can slide past each, this state of matter can be poured.
Liquid
If I combine baking soda and vinegar together and some of the new substance releases a gas into the air, did I just destroy matter? Why or why not?
Answers will vary.
If I combine 37 grams of vinegar with 17 grams of baking soda. How many grams of the new substance would I have after the reaction?
54 grams
What is an educated guess called?
Hypothesis
