Teaching Kids About Science

The basis of science is observing and recording those observations. Sometimes we perform experiments and make a hypothesis about what the results may be. But if you have young children, teaching them about the scientific method may be challenging. An easy and fun way to begin teaching kids about science is to teach them about making and recording their observations.

A fun science project I like to do with my kids is make an observation journal. At the beginning of “quarantine” or the shut down of school, I made a few of these observation journals for my daughters. We made one for birds, plant germination, and measurements. They loved it so much that it is something I have decided to continue. These are also great for younger kids who can draw but not write yet.

How to make an observation journal

All you need to make these journals is:

  • Stapler
  • A few sheets of blank printer paper
  • 1 piece of construction paper

Once you’ve gathered your materials, fold the printer and construction papers in half (hamburger style) and staple them where the binding of a book would be. Viola! You’re done. All you have to do now is decide what you’d like to observe and record.

5 Senses Nature Journal

We recently read the book Who Owns The Sun by Stacy Chbosky. In it there is great use of imagery and many places where she writes about the senses. As a way to incorporate a science lesson into our learning we made a 5 Senses nature journal.

Not only was this a fun experiment, it also helped us get our exercise for the day as we were out walking and running around for about an hour.

Inside the journal I wrote a header for each page. I see…, I hear…, I feel…, I smell… and I taste…(that was a little challenging).

Before we started our nature walk we discussed the 5 senses and what each is. I let them know that they should pay close attention to all the things that they would see and hear along the way. I also let them know that if they saw something that they wanted to touch that they should go feel it and make a note of the texture as well as see if it has any smell.

We started our walk and I had them close their eyes and tell me what they heard. They told me they heard dogs barking, birds chirping, and sirens from a police car. While their eyes were closed I also had them tell me what they felt. They first told me that they felt the paper in their hands but I asked them what they felt without using their hands. They told me they felt the wind and the sun. It was fun to get them to use their senses in a different way than they are used to.

Once we made a few observations we stopped and recorded them. My younger daughter just turned 4 and is learning to write so I had her draw pictures of what she observed and I wrote down what she told me. My older daughter recently turned 6 and is very good at writing. I had her draw pictures as well as write down the things that she observed. We continued to make observations as we walked to the park near our house

Finding something to taste was the hardest part. I wanted them to taste things, but probably not grass or dirt. Even though they have had their fair share of these in the past. When we went to the park we found a huge Bur Oak tree. After doing some research I found out that all acorns are edible, but you can only eat them raw in small amounts because they have a large amount of tannins which are an anti-nutrient to humans. I also found out that if you “leach” them you can either eat them or use them to cook with. Who knew I would learn something while teaching kids about science?

I decided to try and leach them but that didn’t turn out well at all. So I tossed them and we decided to search for something edible in our back yard. One plant that most people see as a “weed” but is actually edible is the common mallow plant or cheese weed (because the fruit looks like wheels of cheese). Here is a great article about the plant and it’s uses. Because all parts of the plant are edible and there were no flowers or fruit at this time of year, we harvested some of the young leaves from the mallow that grow very well in our yard. We washed them and recorded our observations.

Both of my daughters and I tried the mallow plant leaves. My younger daughter tried it and immediately spit it out (she doesn’t like vegetables very much). My older daughter tried it and loved it. She told me she could eat them all day. They are actually quite mild tasting and my older daughter described them as sweet. As we were using our senses with the mallow root, I talked a little bit about the plant and what it has been used for in the past. Did you know that Native Americans used to use the mallow plant as a poultice for wounds and also as a laxative? I had no idea that a plant in my backyard had such an interesting history.

I love these observation journals because they are so simple and most of the time the things you choose to observe are inexpensive or free. Teaching kids about science is so much fun. Doing it in an interactive way is even more fun. This simple project gets everyone involved and learning new things. When we encourage learning through play, our children are more likely to want to learn and to retain more information. So get out there and explore with your little ones and remember to have fun!

Earthquake Experiment

Have you ever experienced an earthquake? I have only been in a very mild one in Southern California. It felt like I was dizzy and the room was spinning. It lasted for a very short time and was over almost as quickly as it began. Imagine being in a severe earthquake where your whole house shakes or buildings topple over. That would not be a pleasant experience. But because we live in California and earthquakes are a very real possibility where we are, I thought that an earthquake experiment would be a great activity for my kids.

Not only does this experiment give us the opportunity for education about the surface of the Earth and the way it moves, but it also gives us the opportunity to learn about earthquake safety and what to do if we ever experience one.

To perform the experiment you will need:

-Jello

-Cookie sheet with edges or shallow baking dish

-LEGOs or other blocks for building structures

Step 1:

Make the Jello and place it into the cookie sheet with edges or a shallow baking dish to set.

This thin layer of Jello will act as the Tectonic plates on the Earth’s crust that move. It is important to try and give the Jello a level surface in your fridge to set otherwise the block structures that you make may have a harder time standing on their own.

IMPORTANT NOTE: Make the Jello the day before you plan to do the earthquake experiment. It takes several hours for Jello to set.

Step 2:

Create an example model for your kids.

Make a tall and somewhat narrow building. This will allow the jiggling Jello to knock over the building with ease.

We chose to use our math manipulative blocks to make our structures.

Step 3:

Place your building in the center of your Jello. If you haven’t already, this is a great time to discuss with your child about the Tectonic plates in the Earth and the different ways that they can move.

Next have your child shake the container of Jello until the building falls. They will have so much fun with this part!

Step 4:

Have your child make their own building that is different from yours and try it out in the Jello to see how stable their structure is.

During this time of your children experimenting with their own structures, it is a good idea to explain what makes buildings stable (foundation, reinforced beams and pillars, center of gravity, etc.) if they are old enough to understand these concepts. If they are younger you might want to talk about what stability means and what you can do to make things more stable.

This was especially fun for my older daughter. She loves LEGOs and building anything she can get her hands on. When I gave her the task of making her own building, she chose to make a bridge. Her first attempt was too narrow with not enough support on the bottom and it fell over almost immediately. I asked her thoughts on why it failed to stand then gave her some additional information about stability. She had the chance to make adjustments and try again. The next attempt she made was much more stable and actually was not able to be knocked over by the Jello.

My younger daughter made a really tall and narrow building with a flat base that fell over almost immediately as well. I explained what can happen if there is too much weight at the top of a building. When she had the chance to make adjustments, she made a very short and wide building. When it was time to test it in the Jello her structure remained standing.

Once you’ve finished with the earthquake experiment it would be a good time to brush up on what to do in case of an earthquake. The U.S. Geological Survey has some good information about what to do in this situation. After introducing the idea to your kids you can make it as fun as possible by acting out an earthquake and taking the appropriate actions to take to keep everyone safe.

We all had so much fun with this earthquake experiment. My girls learned about the Earth’s surface, movement, stability, and gravity all while “playing”. They were so proud of themselves for being able to fix the issues in their buildings and actually have them work out. It was such a great learning experience for them and something that I think will be memorable as well.

Tornado In A Jar

Have you ever seen a video or photo of a tornado? They are so beautiful but so very dangerous. If you can’t go out and observe a tornado, how do you teach your children about one safely? You make a tornado a jar of course.

This experiment is so much fun and very affordable. All you have to do is look around your house for these items and you’ll be making a tornado in no time.

Materials:

1 L bottle or a large glass jar

Water

Liquid Dish Soap

Food coloring

I tried this experiment a few times with different materials before I settled on the best things to make the clearest looking tornado to observe inside your jar.

If your child is old enough, allow them to help you with the steps. If they aren’t, they will have just as much fun watching you do it.

Step 1:

If you are using a 1 L bottle take off the label so that you can see clearly through the bottle.

If you are using glass make sure it’s clear so that you can see what is happening.

Step 2:

Fill the bottle 2/3 to 3/4 full of water.

Step 3:

Add 1 drop of liquid dish soap and 1 to 2 drops of food coloring of your choice (this gives good contrast so you can see the tornado more clearly).

Step 4:

Place the lid back on the bottle or jar and make sure it is on tight!

Step 5:

Swirl the bottle around as quickly as you can to make a large vortex.

Depending on how old your children are, you can choose to have just a fun experiment for them to see, or you can go further into the science behind wind. How there are currents, pressure systems, and even how flour mills were once powered by wind.

Finally, enjoy watching your little one’s amazement as they watch the water swirl around. I did this with my little ones and they were in awe. It was priceless.
