Saint Patrick's Day Science Activities

Saint Patrick's Day is coming.  Rainbows, Leprechaun Traps, green food, and more.  Holidays are a great way to integrate science into your teaching.  Hands-on fun and learning at the same time.  Crafts are great, but when you can integrate it with the magic of science it is much more memorable.  Here are few of my favorite Saint Patrick's Day science activities.

Rainbow Milk 

Whole Milk     Dish Soap     7 inch dessert plates     Eye dropper or pipette
Liquid Food Coloring:  Blue, Yellow, Red, Green     Measuring cup  
1. Pour 80ml of whole milk into the plate.
2. Place one drop of each color of food coloring near the center of the plate.  Try not to let the colors touch.
3. Using the eye dropper carefully place one drop of soap into the center of the colors.  You can also dip a cotton swab in soap and hold it in the center of the plate.
4. Observe the colors swirling.
6. Try again and make some changes.  What will other types of milk do?  Does the type or amount of soap make a difference? 

Leprechaun Trap
This is a fun STEM activity.  I have done it at home with my kids for years.  The idea is simple.  The Leprechaun is coming the house or classroom.  To get him to come we leave out shiny items, because Leprechauns love shiny things.  Coins, dollar store coins, and anything silver or gold works great.  

The kids than create a trap.  These can be made a variety of ways.  The trap needs to fall or catch them when they go in to get the shiny items.  Here are some examples.  The Leprechaun falls into a trap, but can't get out.  Kind of like the Pitcher Plant.  The standard box with a stick.  The leprechaun walks under a box trips the stick and it falls over him.  A sticky floor he gets stuck too.  That one seems a little cruel.   Check out my Pinterest board for ideas.  I remind the kids are goal is to catch him so we can see him and become friends.  We don't want to hurt the leprechaun.  

 Color Separation
This activity is a favorite of mine.  Simple supplies.  You could even take the colorful filter paper and use it to decorate the Leprechaun traps.
Coffee filters     Wet erase markers     Water based markers     Shallow plate     Water
1.  Choose one of the markers.  Draw a circle around the outside of a coffee filter. Leave about an inch of space from the edge. Be careful it may bleed through onto the table.
2.  Fold the coffee filter into a tee-pee.
3.  Pour a little water in the dish.
4.  Place the bottom of the coffee filter into the water.  Make sure it can stand up on its' own.  You also want to make sure the water does not touch the marker.  You want the water to travel up to it.
5.  Observe the water traveling up to the marker.  You should see the colors start to separate.
6.  Try other kinds of markers.  Some will separate and some will not.  The wet ease markers work best.  They separate into a rainbow of colors.
7.  Let the coffee filters dry and then use for crafts.

Check out this great experiment for teaching about Rainbow Milk.  It follows the scientific method.  great for science fairs too.

Dr. Seuss Science Ideas

I just love Dr. Seuss books.  They catch the students attention with fun poems and great pictures.  They can also be used to introduce some great science concepts.  Here are some ways to integrate Dr. Seuss into you science curriculum.  Perfect to celebrate Dr. Seuss's birthday!

Awesome follow up to Bartholomew and the Oobleck. Do an oobleck science experiment!
Read Bartholomew and the OOBLECK and then create some oobleck.  (That's cornstarch and water.)  Find more ideas here.

Kimberly Scott Science is on Instagram

I was one of those people who resisted getting a smart phone.  I have used my flip phone for years.  It was reliable and did what I wanted it to do.  Recently my phone features went out of date.  I knew it was time to update.  I learned more about Instagram and that sealed the deal.  Now I can take and post pictures more easily of my classes performing experiments.  I can also take more videos.  I love the slow motion video feature.  I also love the ability to make movies right from my phone.  I am slow at texting, but I will get there.  I still love my computer.  Typing on a keyboard is so much faster.  My goal is to inspire lifelong learners through a memorable experience.  I think expanding to Instagram and even Twitter will help.

To celebrate I am giving a way a $10.00 Teachers Pay Teachers gift card.  To enter you must visit my Instagram account.  While there consider following me to get great hands on science inspiration.

Did I mention there is also a site-wide sale going on.  Click the image to head on over for great deals.

I even made some slow motion videos with my new phone and turned it into a video preview on my store.  Such a nice feature for to add.  I took the video on my phone and then used Movie Maker and Movie Moments to finish it up.

Reaction in a Bag

My students just loved this activity.  Okay, I did too.  I made a few modifications.  I will have to write that up more formally another time.  Here are the highlights.


I found this activity on a science forum.  The teachers were all talking about how much they loved it.  It is a great way to show students the informal part of the scientific method.  The scientific method isn't always done in the same way.  It is still systematic and precision is important, but sometimes it is not in a formal way by starting with a hypothesis.

The premise is to teach the kids how to discover what substances cause what parts of the reaction.  They first see the complete reaction with all 4 substances.  This will produce heat, foaming, gas production, and a color change.  Then they combine two substances at a time to see what they do together to discover their role in the reaction.  Such a great way to teach about chemical reactions.  All of this is done in a zip lock bag, so clean up is easy.  Performing the reaction in a bag allows them to see the gas production and feel the temperature change.  Some combination will do nothing.  Others will be exothermic or endothermic reactions.  Some will even produce a color change.

Here is the link for the specific directions and worksheets.  It does a fabulous job explaining the science that I won't repeat it here.

Changes to the experiment.

I made same changes to make it more cost effective and use materials I already had.

Calcium Chloride:  I bought Damp Rid at my local superstore.  I use the unscented, which is pure calcium chloride.

Phenyl Red:  I did not have phenyl red, nor the budget to order some.  I decided to use red cabbage juice.  I had a red cabbage in my freezer from a previous experiment.  I boiled it in water until the color was mostly out of the cabbage and in the water.

Red cabbage produced a different change than the phenyl red.  Both are indicators, but produce different color changes.  Red cabbage is an acid/base indicator.  In the reaction with all 4 ingredients it produced a purple color.  Most likely because the substance were neutralizing.  In the presence of a base it will turn more green.  In the presence of an acid it will turn more pink.

When students began testing two items together they quickly noticed that sodium bicarbonate and red cabbage juice turned green.  Sodium bicarbonate is a base.  This really interested them because it did not happen when all 4 substances were mixed.  They were also surprised because the liquid gets cool.  When all 4 are mixed the students feel the heat from calcium chloride and water reacting.

 When the students mixed calcium chloride with red cabbage juice they discovered it turned a bluish/green color.  It did not seem to be quite as strong of a base as the baking soda, but it was close.  In this reaction a lot of heat was produced.  This just makes it even more exciting for students.  They immediately noticed more heat is produced than when all 4 substances were combined.  That is most likely because of the sodium bicarbonate and water losing temperature.

If you have a group of 5th-8th graders I strongly recommend this activity.  It is memorable and really applies higher order thinking skills.  Click the link above for the detailed directions.

Diet Coke and Mentos Exploration

Have you tried Diet Coke and Mentos?  This activity is so much fun at any age.  Students just have a blast.  

Why I love Diet Coke and Mentos?

1.  It is exciting.
2.  It takes simple supplies and creates a great scientific experience.
3.  It is great for teaching about the properties of matter.  Especially Gases.
4.  There is so much science happening.

This activity is so easy.  The bottle is opened and 5 to 10 Mentos are quickly dropped into the bottle.  Almost immediately a huge geyser of soda erupts.  If lucky it can be over 10 feet high. 

This is not a chemical reaction, but a physical  reaction.  Mentos candy contains lots of tiny bumps or nucleation sites.  It is also the correct size and weight to cause the carbon dioxide gas to immediately come out of solution.  The carbon dioxide grabs onto the nucleation sites on the Mentos and the bubbles get bigger and bigger.  These large bubbles force there way out of the bottle with the liquid coming for the ride. 

I really like digging into the science of Diet Coke and Mentos.  Helping students to understand the science behind it is so much fun.   Because it is a physical reaction you don't need to use Mentos.  Other objects and candy can be tested.  It is all in the nucleation sites.  So head to your dollar store for a wide selection of candy to help get started.

This workbook is great.  It will take you step by step through learning about the science behind geysers.  A great addition for the hands-on science class, STEM Club, scout group, and summer camp.  Click to download today.
