Physical Science for Kids: Waves, Forces, Matter, Energy

Here at Growing with Science, our activities are often inspired by children’s books. Today for STEM Friday we are featuring four new titles in the Picture Book Science series by Andi Diehn and illustrated by Shululu (pen name of Hui Li), coming out March 1, 2018. For a review of the books, see our sister blog, Wrapped in Foil.

Activities to accompany and expand upon the books:

Let’s discover more about the topics covered by the books through videos and hands-on activities.

1. Sun Energy

Energy: Physical Science for Kids explains what energy is through examples, such as chemical energy, heat energy, electrical energy, and light energy.

sunflower One question the book asks is whether plants use energy. After all, they don’t run around, jump or even move.

Or do they?

Young sunflowers (and a number of other plants) do orient throughout the day so their leaves catch the most sunlight. You can see more in this video from Science News:

Plants are amazing because they can “capture” the energy from the light of the sun and convert it into chemical energy that we can use.

Sunflower Activity:  Plant a row of sunflowers in the soil. As they grow, observe how they leaves are oriented throughout the day. (Learn about plant parts, flower parts, pollination, and plant life cycles, as well.)

2. Force of gravity

In Forces: Physical Science for Kids, readers explore the concepts of gravity, friction, and magnetism.

Gravity is the force of attraction between two objects with a mass. It varies with how large the mass is, how fast it is moving, and also how close the objects are.

Let’s learn a little more about gravity with this video from Crash Course Kids:

Buggy and Buddy blog has a great activity to show how the force of magnets can overcome the force of gravity.

  • Making parachutes is a good way to investigate the forces of gravity.
  • Making siphons is another way to find out more about gravity (Growing With Science Water Cycle, second activity).

Nomad Press has a children’s book, Explore Gravity!, which has 25 hands-on experiments to try.

3. Matter

What are the states of matter? Solid, liquid and gas are the forms we are most familiar with. There is also a fourth state of matter called plasma, and very possibly others (up to six or seven). Plasma is the most abundant state of matter in the universe by far.

If it is so common, then why hasn’t everyone heard of it? One problem may be the term plasma. Plasma is a word also used for the fluid in blood that carries the cells and other materials from place to place. The same word  has two very different meanings, but that happens all the time in the English language.

The state of matter plasma is a gas that has been energized so much some of its electrons have come flying off. It can also be called ionized gas, but that is confusing because it sounds like it is just a special kind of gas. Plasma behaves differently from gas, and is thus a separate state.

In this video, we see the differences between the three states of matter we are most familiar with:

 

Explore the three most familiar states of matter using an ice cube

Place an ice cube or two on a flat surface outside on a warm, sunny day. Revisit it every twenty minutes and observe what happens.

Expected result:  The solid water (ice) should melt to liquid water. After it has finished melting, if the day is warm enough the liquid should evaporate, which means it has turned to gas (water vapor).

4. Waves

Waves: Physical Science for Kids relates the physical waves that we can see to light, microwave, and radio waves.

In our previous post, Exploring Waves with activities, we discussed how the water in waves doesn’t actually move across the surface, but instead cycles up and down in place. This can be a difficult idea to grasp, but Andi Diehn nails it in her book about waves. She likens ocean wave movement to fans doing “the wave” at sporting events. Each person remains in the same seat, but by rising and lowering creates a wave of movement across the stadium.

To see the properties of electromagnetic radiation and how it travels in waves, see:

Conclusions:

These Picture Book Science books introduce, define, and clarify the scientific vocabulary.  This is important because the physical science topics that these books cover are not mutually exclusive and the overlap can lead to confusion. For example, light energy travels in the form of waves; the force of gravity moves objects, giving them potential and kinetic energy; waves in the ocean can be harnessed to produce electrical energy, etc. Having a clear understanding of the concepts is an important first step to scientific discovery.

Question About Science Experiment Kits for Kids

This week I received a question from a grandmother who wanted to find a hands-on science/STEM kit for her grandchild and wondered if I have any suggestions.

First of all, kudos to you grandma! You have a lucky grandchild!

A few recommendations for deciding on a kit:

  1. Pay attention to the child’s interests. Although they might not be able to articulate them clearly, children are individuals who have particular questions about how the world works and are often eager to investigate them. What does the child gravitate towards? Does he or she like trees, cooking, building things, or wonder how the human body works? Look for kits that feed the child’s passions.
  2. Pick kits that allow for some open-ended exploration, if possible.
  3. Try to find kits that can be used more than once, so the child can build on their learning by revisiting the experiments.

Some examples of commercial kits (Affiliate links go to Amazon):

Scientific Explorer My First Mind Blowing Science Kit

Appropriate for ages six and up, with adult supervision. Comes with supplies for 11 projects/experiments. (Check the video for a better idea of what is included.)

The Magic School Bus – Chemistry Lab

This one is probably for a bit older kids with good manual dexterity. The Magic School Bus kits are well-tested. Some of the experiments require common household items not found in the kit, such as vinegar, salt, pieces of banana, lemon juice, etc. Fun!

Our Family Favorites:

When he was younger, my son enjoyed the physical sciences.

Ben Franklin Toys Geology Lab Pad Science Kit

We found a kit like this one at a yard sale and used it on and off for years.

Snap Circuits SC-300 Electronics Discovery Kit

Be prepared to have to buy stock in companies that sell batteries, but these were favorites that got used year after year for different projects.

Build your own science kit suggestions:

Maybe not for gift giving, but you can also assemble your own science kits (links go to previous posts):

For Educators:

Because I often work with groups of children, I found the classroom kits at Steve Spangler Science helpful. They tend to have a lot of “Wow” factor, which might entice the more reluctant scientists.

Homeschooling High Schoolers?

We were pleased with the science kits from The Home Scientist, but they really are for teens/young adults. You can see how we used the honors chemistry one at this blog.

The bottom line is that no matter what kit you pick, providing some hands-on science is the right choice.

Do you have any suggestions for favorite science kits for children?

Aurora Science for Kids

We’ve been focused on storms here on Earth lately, but there’s been activity on the sun, too. On Wednesday last week (September 6, 2017), the sun produced an unusually large solar flare. This flare results in an increased likelihood of auroras lighting up the night sky here on Earth. To learn more about how this works, let’s look at the timely middle grade book Stories of the Aurora: The Myths and Facts of the Northern Lights by Joan Marie Galat and illustrated by Lorna Bennett.


As the title suggests, Stories of the Aurora is a combination of science and folklore. On the folklore side are legends from Inuit, Norse, Greek, and other cultures. On the science side, readers learn about the Earth’s magnetic field, how the auroras form, how they behave, and the environmental effects of auroras.

It’s a surprisingly informative mix. For example, on page 18 we learn that the Sami (also called Laplanders) call the aurora “The Light You Can Hear.” This might not make sense until the sidebar on page 30, when we learn people for centuries have reported hearing crackling and hissing sounds during bright auroras. In 2012 scientists were able to verify the sounds and lights were related and began to piece together how they are created.

In this video you can hear some recordings of the sounds (towards the middle of the lecture, about 1:30).

Sometimes they sound like clapping. Isn’t that amazing?

Auroras making sounds is just one of the cool things readers will discover in Stories of the Aurora. This award-winning title will surely light up the faces of youngsters interested in finding out more about their world.

Science of Auroras

The Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights) occur when waves of charged particles traveling as solar winds from the sun strike the gases in the upper atmosphere of the earth and make the gases glow. The Northern Lights typically occur around the Arctic Circle, but large flares can cause a glow that can be seen throughout Canada and into the northern United States. Here is a photograph of an aurora taken in Wisconsin.

Activity Suggestions:

  1. Predicting when an aurora will occur is difficult, and at best happens only two or three days after an observed solar flare. Often scientists can only give about 30 minutes notice. Check the NOAA Aurora website to learn about current predictions.
  2. Visit the author’s website for a list of links to cool aurora and general astronomy sites to visit.
  3. Collect images of auroras. Make a poster, lapbook, or slide presentation explaining how they form and facts about them. For example, find out why are some auroras green, some red and some a mix of colors. Share your results. NASA has a free .pdf aurora poster and lesson to get you started.
  4. Try an art project with colorful auroras as a backdrop to arctic animals. Oil pastels on black paper can give a lovely effect. Add some black silhouettes of trees or land forms to the bottom for contrast.

The book is the 2017 SCBWI Crystal Kite Award winner for the Canada region and 2017 Skipping Stones Honor Award winner.
