This fun project teaches kids about paper science and lets you keep a little bit of summer growing all year long. You can find instructions on the video below, from my Kitchen Pantry Scientist YouTube channel. (Follow me there for loads of fun science projects!)
My latest book is out just in time for summer! Biology for Kids pairs short bios, beautifully illustrated by artist Kelly Anne Dalton, with related science projects, including step-by-step instructions and color photographs. (Available everywhere books are sold.) Amazon link here.
Here’s a TV segment where I demonstrate a few projects from the book:

Summer is almost here, and so are the bugs! Here’s a short video segment featuring two inspiring scientists, paired with fun projects from my new book, “Biology for Kids” (available everywhere books are sold.)
It’s fun to create colorful, swirling marbled designs on eggs, and there’s science behind the fun! Here’s a brief description of each. Click on the blue titles for more instructions and science explanations.
Olive Oil Marbling: You’ll need hard boiled eggs, olive oil, vinegar, and food coloring. We used green, yellow and brown food coloring to make robin’s egg colors.
Natural Dyes: Experiment with fruit, coffee, tea, spices, veggies and even onion skins to create beautiful, natural egg dyes.
Nail Polish Marbling: This one is obviously inedible, but it’s a fun craft project! You’ll need eggs with the yolks and whites blown out, a container that can be thrown away, nail polish in two or more colors, and water. (Project from STEAM Lab for Kids-Quarry Books)
The science behind the marbling fun: Egg dyes and food coloring require an acidic environment to form bonds. That’s why you add vinegar (also called acetic acid) to water and dye when coloring eggs. Things that are less dense than water, like olive oil and nail polish, float on top of water, allowing you to create designs that can be transferred onto your eggs.
So excited for Biology for Kids’ book release on May 11th! Here’s a sneak peek at a few projects from the book. Pre-order now from your favorite bookseller or click here to order.

Grab an extra bag of cranberries this Thankgiving! Kids can use it to reveal invisible messages they write with baking soda and water.
-around 2 cups of cranberries
-small paintbrush, Q-tip, or lollipop stick
Safety tips and Hints:
Boiling the berries should be done by an adult. Keep the lid on the pan, since the air pockets that make cranberries float can also make them explode. Kids can take over once the juice is cool.
When playing with cranberry juice, aprons or old clothes are a good idea, since it stains!
Step 1. Cut a cranberry in half and observe the air pockets that make it float.
Step 2. Boil the cranberries in about three cups of water for 15 to 20 minutes, covered. Listen for popping sounds as the air in the cranberries heats up and they explode.
Step 3. Crush the cooked berries and push the liquid through a sieve or colander to collect the concentrated cranberry juice.
Step 4. Allow the juice to cool and pour it into a casserole dish or cake pan big enough to hold a piece of paper. If your cranberry juice seems thick and syrupy, add a little water, so that it’s thin enough to soak into paper!
Step 5. Test the paper you want to use by cutting a small piece and soaking it in the cranberry juice. If it stays pink, it will work, but if it turns blue or gray, try some other paper.
Step 6. Add a few teaspoons of baking soda to 1/3 cup of warm water and stir well. Don’t worry if you can still see some baking soda.
Step 7. Using a Q-tip, paintbrush, or a homemade writing tool, use the baking soda solution as ink to write a message on your paper. It may take a little practice, so don’t get frustrated.
Step 8. Let your message air dry, or speed things up with a blow dryer.
Step 9. To reveal your message, place your paper in the cranberry juice and see what happens!
*What other natural acid/base indicators could you use to do this experiment? What else could you use as ink.
The Science Behind the Fun:
Cranberries contain pigments called anthocyanins (an-tho-SY-a-nins,) which give them their bright color. In nature, these pigments attract birds and other animals to fruit. This is important because animals eat the berries and spread plants seeds from one place to another.
These pigments, called flavanoids, change color when they come in contact with acids and bases. Cranberry juice is very acidic, and the pigment is pink in acids, but when you add it to a base, it turns purple or blue.
Baking soda is a base, so your baking soda message will turn blue when it comes into contact with the pigments in the cranberry juice. Eventually, when enough cranberry juice soaks into the paper, it will dilute the baking soda, turning the pigment back to red and your message will disappear!
There are over 300 kinds of anthocyanins which are found in many fruits and vegetables including blueberries, red cabbage, grapes and blueberries. Scientists believe they may have many health benefits.
Wednesday, April 22nd is Earth Day, but there’s no reason we can’t celebrate all month long. Besides hiking and exploring, here are some of our favorite environmental science projects. Just click on the experiment names for directions and photos. You can find more fun outdoor experiments in my books “Kitchen Science Lab for Kids” and “Outdoor Science Lab for Kids“ (Quarry Books.)
Homemade Sweep Nets: Make a sweep net from a pillowcase and a hanger to see what arthropods are hanging out in your favorite outdoor spaces.
Window Sprouts: Plant a bean in a plastic baggie with a damp paper towel to see how plants need only water and air to sprout roots and leaves. Here’s a short video demonstrating how to make a window garden.
Homemade Solar Oven: Using a pizza box, aluminum foil, plastic wrap, and newspaper, you can harness the sun’s energy to cook your own S’mores!
Nature Walk Bracelets: Wrap some duct tape around your wrist (inside out) and take a walk, sticking interesting natural objects like leaves and flowers to your bracelet. It’s a great way to get outdoors and engage with nature. Bring a bag along so you can pick up any trash you find.
Carbon Dioxide and Ocean Acidity: See for yourself how the carbon dioxide in your own breath can make a water-based solution more acidic. The project illustrates why adding too much carbon dioxide to Earth’s atmosphere can be harmful to ocean creatures.
Plant Transpiration: See how trees “sweat” in this survival science experiment.
Earthworm Experiment: Do you know what kind of earthworms are living in your back yard?
Composting: Be a composting detective. Bury some things in your back yard (away from power cables) and dig them up in a few months to see how they look. Composting reduces methane gas emissions (a greenhouse gas) from dumps.
Diffusion and Osmosis: See for yourself how the chemicals we add to water, put on our streets to melt ice, and spray on our lawns and crops can move into our soil, ground water, rivers, lakes and oceans.
Solar Water Purification: This project illustrates the greenhouse effect and is a fun “survival science” experiment. Requires hot sun and some patience!
Citizen Science: Don’t forget about all the real environmental research projects you can participate in through Citizen Science programs all around the world!

Physics! Biology! Chemistry! Yeah!
Great job staying isolated to help keep everyone safe! Keep up the good work! Scientists and medical workers are busy testing anti-viral drugs and creating vaccines that will help us to help get life back to normal as soon as humanly possible. They are the superheroes we need right now!
