- 2. The study of energy, forces, motion, and the way things work.
- 3. A state of matter that has no definite shape or volume and fills any container it occupies.
- 5. How far apart two objects are from each other, often measured in meters.
- 7. The study of space, planets, stars, and galaxies.
- 11. The amount of matter in an object, often measured in grams or kilograms.
- 13. The basic unit of life, which is capable of carrying out all the functions necessary for an organism to survive.
- 15. The study of matter and how it changes when mixed with other things.
- 16. Describes a substance that readily undergoes chemical changes or reactions. It is unstable and possible explosive.
- 18. (gas) An element in the group 8 of the periodic table that is generally unreactive due to its full outer electron shell.
- 20. (respiration) The process of turning glucose into energy without using oxygen.
- 22. The smallest particle of an element that retains the properties of that element. It makes up everything around us.
- 23. A substance that is dissolved in a solution, typically the smaller component of the mixture.
- 24. The force that pulls objects towards each other.
- 26. The ability to do work or cause change.
- 27. Anything that has mass and takes up space.
- 28. The process by which living organisms convert oxygen and glucose into energy, releasing carbon dioxide and water as byproducts.
- 29. The substance that dissolves another substance in a solution.
- 30. A state of matter that has a definite volume but takes the shape of its container.

- 1. The study of living things, like plants and animals.
- 4. (respiration) The process of turning glucose into energy using oxygen.
- 6. A type of mixture in which one substance is dissolved in another to create a homogenous mixture.
- 8. A unit used to measure force. Named after the scientist Isaac.
- 9. A type of chemical bond where atoms share electrons to form molecules.
- 10. A push or pull that makes an object move or stop moving.
- 12. How fast something is moving, often measured in meters per second.
- 14. The process by which plants convert light energy into food.
- 17. How long it takes for something to happen, often measured in seconds or minutes.
- 19. A type of sugar that our body uses to make energy.
- 21. metals A group of elements in the periodic table that are highly reactive and easily lose 1 electron to become stable. They are in group 1.
- 25. A type of chemical bond where atoms transfer electrons to form molecules.
- 29. A state of matter that has a definite shape and volume.
