HOME CHEMISTRY

Science Badges:

1. Home chemistry
2. 15 Points are needed to get a badge
3. Work to a very high standard that means:

• All experiments are written up ( Aim, Materials, Steps, Conclusion)
• Two photos of your experiment
• 6 sentences at least for a conclusion

Aim: To learn the names of 10 household chemicals and identify if they are a solid, liquid or a gas.

Definitions:

1. Element; A single form of a chemical 
2. Compound: A mixture made up of 2 or more elements
3. Reaction: A process in which chemicals mix together to form a new substance.
4. Mixture: When two or more elements are mixed together.

Repeat the steps for all the chemicals.

Task 1: Put the 10 chemicals in a chart with the titles - Name, Chemical ingredient(s), Image, Solid/Liquid/Gas.

Name	Chemical	Image	Solid/Liquid/Gas
Salt	Sodium Chloride		Solid

CONCLUSION: ( WHAT DID YOU LEARN OR SEE) today I LENARD about DIFFERENT tapes of chemicals of names
