Learning through Play: Sand Art

Learning through Play: Sand Art

Sand art is a great activity for toddlers, preschoolers, and even older children.  It can be messy though, so be prepared with a tarp or create your artwork outside.  The pinching and controlled work will improve younger children’s fine motor skills and patience.  They will explore the texture of sand and the way it moves.  You can discuss art, culture or science with older children as they create this artwork.

The Projects

You will need colored sand, or sand, trays, and liquid water color.  You will also need paper and glue or sticky boards, sand paper, and crayons.  Pencils, spoons or funnels may also be used.

If you would like to create your own colored sand rather than buying dyed sand, it is possible. Spread some sand out on a tray and add a little liquid watercolor.  Liquid water color will work better here than food color, which tends to clump more.  Use your hands to spread the color throughout the whole pile.  You can add more color if you feel the sand needs it, but don’t allow the sand to become too wet.  Allow the sand to dry, stirring it occasionally with your hands.  Be sure the sand is fully dry before moving it into a storage container, otherwise the sand can grow mold and will clump.

Once your sand is dry, there are many different activities to do with it.  One of the most popular is to fill bottles with the sand.  Choose a fun bottle to display and the colors you would like to layer inside.  It’s recommended to use a funnel to help channel the sand into the bottle.  Use a spoon or pinch sand into the funnel.  Change colors as needed to create your layers.  Fill the bottle as full as possible, as loose sand will shift over time.  If the bottle is full, the pressure of the sand will keep the layers in place.  Add a lid.  Although this is beautiful art, you can also look at it as a representation of the Earth’s layers for an added lesson.

Another type of sand art that is created worldwide is the mandala or rangoli, which are both impermanent forms of art that take great patience and care.  Mandalas are created by monks as a form of prayer and meditation.  Housewives create rangoli as a blessing for the house.  The Navajo Medicine Men also created sand paintings, which was also impermanent.  Working with sand offers a great medium for temporary art work, which can make the artist ponder their work.  Ask yourself how you feel about your hard work being destroyed.  You can create a temporary piece of work, or create a more permanent piece of art if you prefer.  You can plan your design ahead by drawing it on a piece of paper.  You can look up some of the designs used in rangoli, mandalas, or Navajo sand Art to get some ideas.


For temporary work, you can draw an outline with sidewalk chalk outside and sprinkle sand as needed.  For a more permanent piece, you can use paper and glue or sticky boards.  Remember not to pile the sand too high, as the sand needs to touch the glue or sticky board to stick.  The sand that doesn’t stick can be reused as rainbow sand.  Just collect all the extra sand of the various colors together.

You don’t need colored sand to create sand art.  Many cultures built things using sandstone and would create works of art on these walls.  The artists would need to consider the way the texture of the sand would affect the final product.  You can experiment with crayons and sand paper to simulate this.  Remember to use crayons, not markers, as the tips could become ruined.

Some Information to Share

There are multiple layers hiding under the Earth’s surface, as your sand bottle can represent.    The Earth’s layers are: the crust, the mantle, the outer core, and the inner core.  Above the crust is the layer of dirt and silt on the surface.  Underneath the surface dirt and the debris left with time is the crust, which varies in thickness and is made mostly of alumino-silicates.  Under the crust is the mantle, both the upper and lower mantle.  Together the whole mantle is about 2900 kilometers thick.  Convection leads to the circulation of heat through the mantle which is theorized to be responsible for the movement of the tectonic plates.  The center of the Earth is the core.  The outer core is 2300 kilometers thick and is composed mostly of a nickel-iron alloy, with as much as 10% of the core composed of elements lighter than iron alloy.  The outer core is a liquid, but a less viscous liquid than the mantle.  The inner core is solid because of the pressure from the weight of all the other layers.  The inner core is 1200 kilometers thick and almost entirely iron.  The entire core is through to contribute to the Earth’s magnetic field.

People around the world create sand paintings.  Some of the most common are called mandalas, which are mostly associated with Tibetan monks, but were also made by Native Americans.  The early Christian nun Hildegard von Bingen is well known for her mandalas as well.  Mandalas are created from colored sand as a reminder of the impermanence of life.  Work on the mandala may require many hours or days, but after the mandala is finished, it is swept into a jar and emptied into a nearby body of water as a blessing.  Another form of sand paintings are the rangolis or kolams created by Indian women.  They are mostly made with colored flour, but colored sand, flower petals or colored rice powder might also be used.  Rangoli and kolams are made in the doorway for two reasons.  Firstly, since the Hindu principle of dharma states that one should serve animals and humans alike, the colored flour or rice powder might be used to feed insects.  Secondly, the artwork welcomes Laksmi, the Goddess of Prosperity into the home.  Symmetry is key in this artform as it represents balance.  They also often incorporate geometrical shapes, animals, fruit, and flowers.  The lotus is a favorite to include.

Some of the most famous art created on sand or stone surfaces is that of the ancient Egyptian artists.  Stone surfaces were prepared for painting with whitewash or a layer of course mud and plaster.  Limestone was often painted directly.  This often left the paintings with some texture.  The artistic style was influenced by even more ancient African cultures and near-Asian cultures.  The styles were settled upon in the Old Kingdom, and as artists had little desire to create their own styles, they tended to copy the accepted art forms.  Typical colors for artwork included red, blue, black, gold, and green.  When painting gods, either an animal form or a human with an animal head could be shown.  For example, Anubis could be shown as a jackal or as a human with a jackal head.  Images of people also followed rules.  Faces were painted in profile except the eye would be shown as if from the front.  The top half of the body faces the viewer so both shoulders can be seen.  Arms and legs are often shown in motion.  Feet are shown with the big toe closest to the viewer.

Book Review: Brain Rules for Baby by John Medina

Book Review: Brain Rules for Baby by John Medina

If you are interested in the science of your developing child, this book helps to translate it into language most people can understand.  John Medina prefers to use research that has appeared in peer-journals and has been replicated.  He uses analogies like a three-legged stool, dry rubs, and the Golden Gate bridge to help explain the science and reach a wider audience.

Medina offers simple advice based on this research.  He looks at pregnancy and how some of the things we do can affect the baby later.  He discusses your relationship with your spouse and how we need to approach the challenge of raising children with empathy for one another and how the stress of parental tension can affect even really little ones.  For guys, the relationship portion of this book might really help you understand why your significant other might snap at you.

Once the baby is born, he breaks down the topics of “smart baby” and “happy baby” into the seeds and soil, then discusses the moral baby.  The seeds, or nature, are already decided for you for the most part.  This gets deeper into the science of brain development and psychology.  The soil, or nurture, is the ways your actions affect your child.

When it comes to “smart” babies, he notes that there are challenges in measuring intelligence.  The IQ test, which most people associate with measuring intelligence, comes in many different forms and faces challengers.  He briefly mentions Howard Gardner’s multiple intelligence theory, but does not really discuss it.  Medina brings up some of the more popular movements in intelligence building including limiting screen time, sign language and music.  He also mentions studies that examined educational baby DVDs.  He also stresses how the brain will only allow people to learn if they feel safe.

When it comes to “happy” babies, the first thing parents must decide is what it means to them to be happy.  He helps explain how the brain understands emotions as well as the difference between emotions and feelings.  Both in the chapter on moral babies and happy babies, he stresses the importance of empathy and discussion.  Young children often don’t know how to express these big, overwhelming feelings that sometimes swell over them.  Parents should take a moment to get at their level and try to talk through what the child might be feeling in a way they can understand.  Once children have a grasp of their own emotions, they can then practice transferring those ideas onto others.  In a similar way, most parents will find that children obey rules better if they understand why those rules exist.  Talking about the rules does not mean that there should be not punishment though.  Medina discusses the importance of punishment and the different shapes it may take.

This book is nice because it is a way to learn about some scientific research in child development without having to have a subscription to multiple peer-reviewed journals and wade through the sometimes overwhelming scientific jargon.  Even when Medina uses scientific jargon, he then offers an easier to understand explanation.

Exercise While Pregnant

Although exercise is generally thought to be beneficial for pregnant women, there are complications which may prevent certain women from exercising.  A doctor’s approval is always advisable. 

The changes to the body mean that while exercise in general is good, there are precautions.  Aerobic exercise is great, but make sure you can still speak while exercising to ensure enough oxygen makes it to your little one.  Avoid contact sports, of course, and activities like biking, which can be difficult as your center of balance shifts.  Yoga is another great exercise, but make sure you are doing prenatal yoga, as certain poses and twists are ill-advised after the first trimester.  And don’t try to break any personal records, but if you were running before you should be fine to run again.

The Research for Moms
Doctors used to advise against exercise during pregnancy.  However, research has shown that there are many mental and physical health advantages to exercising during pregnancy.

Exercise helps release endorphins, which help keep you in a better in a better mood.  Exercises like water workouts, yoga and pelvic tilts can help lessen back pain and reduce swelling and leg cramps.  Less pain also means better mood.  Pregnant women who exercise tend to put on less excess weight than those who do not, which helps provide a better body image during pregnancy, and a sense of security that it will be easier to lose the weight once the baby is here.  Exercising can help give you a sense of control over at least that one aspect of your pregnancy as well.  Exercise also will help keep you in a better mood by keeping you more energized and well-rested.  Increased oxygen from aerobics helps keep energy up, and the workout can help tire you enough to sleep better.  After pregnancy, the mood lifting benefits may still exist, as moms who exercised are more likely to be social, enjoy hobbies, and cope well with the demands of motherhood.

On the physical health side, exercise helps reduce the risk of gestational diabetes by as much as 27% and can prevent the need for medication if you do develop gestational diabetes.  Gestational diabetes can cause premature birth and also is linked with overweight babies.  Exercise lowers the risk of preeclampsia, which is the number one cause of premature birth.  Progesterone, one of the pregnancy hormones, can cause constipation but the increased blood flow from exercise can help keep you regular, especially partnered with a high fiber diet.  Moderate exercise can help prevent colds, which can seem worse during pregnancy since so many medications are not available to you.  The physical benefits also continue after pregnancy, as women who exercised during pregnancy tended still show benefits such as lower cholesterol and resting heart rates later in life.

Both the physical and mental preparation from exercise can help when the big day finally arrives.  Studies show that regular attendees of prenatal water aerobics were 58% less likely to ask for pain medication while in labor.  Also regular exercisers were 75% less likely to require the use of forceps, 55% less likely to have an episiotomy (a cut to the perineum to enlarge the birthing canal), and were up to 4 times less likely to have a C-section.  Active labor also tended to be shorter by about 2 hours for regular exercisers.  These benefits are linked to a stronger cardiovascular system and core muscles from aerobic exercise and the better ability to stay calm and relax during discomfort achieved through yoga.

The Research for Babies
Exercise may not just benefit the mom-to-be.  Many recent studies have been conducted to help create a better picture of how exercise can benefit the baby.

Obesity is a large problem in many parts of the world, even in young children.  Regular exercise can decrease the chance of a baby being born overweight.  This excess fat can linger, increasing the likelihood of the child becoming an overweight kindergartener.  If the mother of the overweight newborn had gestational diabetes, this increases the child’s risk of having gestational diabetes.  A healthy birth weight can also help newborns overcome the stresses of childbirth faster.

Exercise can also affect the newborn’s heart.  A 2010 study shows regular exercise during gestation can lower the heart rate of the fetus; this effect is shown to persist for at least a month after the baby is born.  A low heart rate is evidence that the infant’s heart is healthy.  An additional study has shown that exercise while pregnant can alter the vascular smooth muscles of the fetal heart, creating arteries that are more resilient and efficient.  This increased efficiency appears to last into the childhood years, evidenced through higher cardio fitness levels.  This also has the potential to reduce susceptibility to cardiovascular disease.

Most recently, studies have been showing that women who exercise while pregnant can stimulate brain development.  Studies from the University of Montreal showed that as little as 20 minutes of exercise three times per week while pregnant can improve a newborn’s brain activity.  Babies in this study had more fully developed brains at 8-12 days old.  They were better able to process repeated sounds than their counterparts whose mothers had not exercised.  Other studies show that kids whose mother worked out during pregnancy have better memories, and higher scores on intelligence and language tests.

Personal Perspective
Personally I chose to work out while pregnant for two reasons.  The first being the benefits to the baby.  If my exercising can help my child be more intelligent and healthier, I am perfectly willing to put in the effort to exercise.  Secondly, I broke my hip in two places in a car accident in college and was concerned about childbirth.  I hoped by strengthening my muscles, I would be better prepared.  My workout routine included yoga, walking, Gaiam’s Pregnancy Fit Plan and the What to Expect When You’re Expecting workout dvd.

I did experience many of the benefits.  Although I did experience some pregnancy fatigue, it was not nearly as bad on days I exercised.  Constipation was never a problem.  My mood remained mostly positive throughout the experience, even with the added challenge of moving across country in the middle of my pregnancy.  However, I cannot claim that exercise helped with labor at all.  My injured hip caused severe pain and my stubborn little one didn’t want to turn her head the right way so I still needed epidurals and forceps.


Gaiam’s Pregnancy Fit Plan

This blog is a collection of my research as a parent.  It contains information about pregnancy, parenting, and education.  It is my belief that parents can and should help their children reach beyond the classroom and find the fun in learning.  That said, I will include small activities I have used in my years as an informal educator and lessons that tie in with these activities.  Children learn best when their interests are peaked and they can have fun.

The information contained here is a collection of research and not intended to provoke argument.  I try to include pros and cons when I do research to more thoroughly understand a topic.  My conclusions may not work for you, because everyone is unique.  Also, although health is an important topic in pregnancy and parenting, the advice included here is general and your situation may be different so make sure you include the advice of your medical professionals in making your decisions.
