Description

Bring chemistry to your kitchen with a book that offers hands-on science activities that can be done with ingredients from your pantry and the refrigerator! What's going on when you cook in the kitchen? Science!In Kitchen Chemistry: Cool Crystals, Rockin' Reactions, and Magical Mixtures with Hands-On Science Activities, readers ages 9 to 12 discover that the cooking, mixing, and measuring you do in the kitchen all has its roots deep in science-chemistry to be exact! Starting with an exploration of atoms and molecules and how they make up the world, Kitchen Chemistry goes on to discuss mixtures, reactions, states of matter, solutions, and more! By using familiar scenarios such as boiling water, baking cookies, and creating slime, kids make text-to-text, text-to-self, and text-to-world connections that deepen their understanding of the world around us and the connection to chemistry to be found in every area of life. This title has been revised and updated to reflect 2020 educational standards and incorporate new scientific discoveries!* Kitchen Chemistry brings science to life in ways kids find easy to replicate and fascinating to accomplish. * Hands-on projects and experiments, such as making an Alka-Seltzer rocket, building a foamy volcano, and creating crystals, reinforce learning and enhance critical and creative thinking skills. * Essential questions, cool trivia, and links to online primary sources all add up to an inspired time in the kitchen learning chemistry!About the Build It Science set and Nomad PressKitchen Chemistry is part of a set of four Build It Science books that explore accessible science.

CHEMISTRY MATTERS!

Introduction

Wat makes someting soFt or ard? Wat makes someting a soid, iquid, or gas? Wy does water cange From soid ice to iquid water to water vapor?Chemistrycan te you! Cemistry is at te eart oF ow everyting works—it’s te science oF cange.

You mîgt tînk tat cemîsts are peope wo work în abs and wear wîte coats. But tat’s not necessarîy true! Cemîstry îs everywere and cemîstry can be studîed everywere—încudîng în your kîtcen, cassroom, and backyard. And anyone can expore cemîstry wît un experîments and actîvîtîes. he rue îs to ESSENTIAL QUESTION keep ît sae. What is chemistry? WORDS TO KNOW

water vapor:the gas state of water. chemistry:the study of the properties of substances and how they react with one another.

KITCHEN CHEMISTRY

WORDS TO KNOW

matter:anything that has weight and takes up space. Almost everything is made of matter! atom:the smallest particle of matter that cannot be broken down by chemical means. An atom is made up of a nucleus of protons and neutrons surrounded by a cloud of electrons. molecule:a group of atoms bound together to form matter. solid:one of the three states of matter. The particles in a solid are bound together tightly. A solid has a deﬁnite shape and volume and does not ﬂow. liquid:one of the three states of matter. The particles in a liquid cluster together and ﬂow. A liquid has a deﬁnite volume, but takes the shape of its container. gas:one of the three states of matter. The particles in a gas are not bound to each other and move very fast in all directions. A gas does not have a deﬁnite shape or volume. interact:how things act when they are together.

—MATTER it’s all matter!

Matter îs made up oatomsand molecules, known as te basîc buîdîng bocks o matter. hînk o a bucket u o water. hîs bucket contaîns more moecues o water tan tere are buckets o water în te entîre Atantîc Ocean! Atoms are pretty sma.

States of Matter There are three common states of matter:solid,liquid, andgas. With enough heat or cooling, a substance can change from one to another. A good example is liquid water, which when heated can change into water vapor, or if cooled can change into ice. Ice can melt back into water and water vapor can cool to change back into liquid water. When you see water droplets form on the outside of your cold glass of lemonade on a hot summer day, that’s an example of water vapor changing into liquid water.
