Chemistry Experiments for Kids (Grade 2) – Matter is Neither Created Nor Destroyed — Acids and Bases

This semester we’ve been doing a Chemistry Unit for science. We tend to do our science and history units together. In the next two posts, I wanted to share some of the activities I did that were more geared toward my youngest (my older kids have done these before).  Then after that I will share the chemistry materials my older two (grades 5 and 7) have used as we’ve delved into a pretty big unit on the Periodic Table.

We used Real Science-4-Kids Chemistry pre-Level I (affiliate link) for ED (who is 7 and in Grade 2).  This student textbook is absolutely at the perfect level as an introduction to chemistry. My daughter really enjoyed the illustrations and the analogies used were really useful.  She really was able to understand the concepts being explained.  We generally just read one chapter together and another day would do a science experiment together (we don’t have the lab book or other resources you can purchase with this series, though they are available). This book covers some challenging topics, but in a way that my daughter really understood (but of course we’ll cover this material again in 2 or 3 years).  I had my older two read through this book again as well.  For them it was a very quick read.

Another great chemistry book for kids is Explore Atoms and Molecules with 25 Great Projects. (affiliate link) It has a lot of wonderful hands-on activities for kids just learning about chemistry!

If you are looking for a really cute way to introduce young kids to the elements, you might get Amber’s Atoms. (affiliate link) It introduces kids to the first 10 elements of the periodic table. The illustrations are really pretty. It’s a really engaging way to introduce chemistry in it’s simplest form.  Each element has a large picture of the atom (showing the nucleus and electron cloud).  The target age range is 2-5, but if you are introducing your kids to chemistry (and going into more detail) it might be worth it to get this for a 6 or 7 year old. You can have a really good discussion about the number of electrons and so forth.  🙂

Chemistry Book for Young Kids

I wanted to share some of the experiments that we did to go along with some of the material in this book. Today I’m going to talk about the first two:

  • Matter is Neither Created Nor Destroyed (Molecules switch atoms) – Chapter 3
  • Acids-Bases – Chapter 4

You will find the other three chemistry activities we did here (and in the free pdf printable you’ll find at the bottom of this post:

Matter is Neither Created Nor Destroyed (Molecules switch atoms)

This first experiment helped prove the concept that matter is neither created nor destroyed.  We have done the vinegar – baking soda experiment many times before, but in this particular experiment we showed that during the reaction no matter was destroyed. We did this by weighing everything before the chemical reaction and then weighing it after.  We kept the gases “trapped” with a balloon.

See the blooper in the picture to the right below?!!  The first time we did the experiment, some of the gas escaped. We did it a second time with two balloons.

Chemistry-Experiment-MatterWe filled the balloon with baking soda. We put vinegar into our bottle.

Weigh the bottle before adding the baking soda to the vinegar.  Make a note of the weight.  Then carefully let the baking soda in the balloon mix with the vinegar in the bottle.  Hold the bottle steady. Then carefully weigh the bottle again.  It should weigh the same, helping students understand that even though a gas was produced from the reaction, the weight of the materials remained the same.

Be sure to hold the bottle while the reaction takes place!!

We used two balloons to make sure no gas escaped.

I took a picture below for you, but after we took the photo we placed the orange balloon over the lip of the bottle too.

This experiment is always such a hit with the kids! ED was quite little when we did it last time.  We read the section about acids and bases in the student text book.  We talked about the different properties of acids and bases.  Acids tend to be sour and include things like vinegar, lemons, oranges, batteries and other things. Bases tend to be bitter and include things like soap, cleaners, bananas and dates.

To make the indicator, chop up a red cabbage (you can also buy it pre-chopped).  Boil it for 10 or 15 minutes, then let it soak for several hours. After it cooled, I covered it and put it in the fridge for the next day.

We filled our test tubes about half way.

Red-Cabbage-IndicatorED went around the house gathering things to test.  She chose vinegar, lemon juice and a tangerine.  For the bases she chose a date (which we smashed up), window cleaner, bathroom cleaner, and baking soda.  The results were really impressive!

The date never did change the cabin indicator. The date was the one in the middle. 🙂

States of Matter Unit - worksheets and activitiesStates of Matter WorksheetsWe also have a basic Introduction to Chemistry Packet – The Size of Atoms Activities  The activities in this packet are designed to help kids understand how incredibly small atoms are compared to other things (such as DNA, viruses, cells, frog’s eggs and other things up to the size of mice). It also introduces students to some really small measurements – the nanometer and micrometer. This is included in our Chemistry BUNDLE.
