Slinky Waves

Have an old slinky collecting dust in the kids' toy box? Pull it out and teach a quick lesson on the two types of waves. 1. Loosely stretch the slinky across the floor or long table with you holding one end and your child holding the other. 2. Create a transverse wave by shaking one end of the slinky horizontally across the floor or table. Continue shaking back and forth to set up a series…

Growing Bacteria at Home

First, a warning . . . if you grow bacteria at home there is always a possibility you could grow large amounts of harmful bacteria that could make someone in your household sick. Always use proper safety precautions when growing bacteria! Some safety hints are included below, but always, always use common sense when handling any bacteria culture. When bacteria cultures are grown in the lab the bacteria is grown in shallow containers (Petri dishes)…

Growing Crystals with Common Chemicals

Crystal growing is a fun activity for kids and it is relevant to several areas of science, such as chemistry, as well as mineral formation in geology. Schools often use commercial chemicals to grow crystals in the classroom, and these chemicals can be difficult, if not impossible, to purchase as an individual. Here are a few household chemicals that can be used to grow crystals at home: Aluminum potassium sulfate (alum) can be purchased in…

Cooking Up a Chemical Change

Chemical change can be a hard concept for children to understand. It's much easier to explain a physical change. Water freezes into ice. The ice is still water and can be melted back into liquid water. Tear a piece of paper in half, and you still have the same paper. Both are physical changes. But how do you demonstrate chemical change? The easiest example of a chemical change is burning a piece of paper. The…

Backyard Ecology

No matter whether you live in the country or the city, your child can observe nature close to home. Help your child be a nature detective to discover the ecosystem existing right in their own backyard. First, help your child identify what types of plants and animals they are realistically likely to see. If you have land in the country they're likely to observe large mammals such as deer and racoons. If you have a…

Outdoor Activity Explains Energy and Work

Energy is defined as the "ability to do work." Energy and work are really different forms of the same thing, but to a child, they are very different. Try this simple outdoor summer activity to demonstrate the relationship between gravitational potential energy and work. First, children need to understand gravitational potential energy. Explain to your child that a ball on the floor has no potential energy because it won't move by itself. But, a ball…

Periodic Table Basics

If your child has already learned about the parts of an atom (proton, neutron, and electron) they can understand the basics of the periodic table. From a basic periodic table, a young student can find: 1) the abbreviation for the element's name, 2) how many protons an atom of the element has, 3) how many neutrons an average atom of the element has, 4) the number of electrons a neutral atom of the element has.…

Understanding and Measuring Friction

For elementary children, the topic of "opposing forces" can be hard to understand. Friction is an opposing force that children can "feel." Here's a lab on measuring and comparing friction that's appropriate for older elementary children. You will need one piece of "science equipment" to get the most out of the lab . . . a spring scale. A spring scale with small increments will be easier for elementary children to use. Here's what to…

Learning about Earth’s Past through Creative Writing

Most kids love to be creative and make up stories. Use that creativity to research Earth's past. Depending on the age of the child, you might want to first introduce them to the Geologic Time Scale. Here's a good website with some basic information from Britannica Kids. For younger children, you might just help them pick a topic from Earth's past, such as "dinosaurs." Next, help your student narrow down a specific time period (or…

Calculate Speed While Encouraging Exercise

We all know that kids have a lot of energy. Put that energy to good use by combining a physics lesson, a math lesson, and some good exercise! All you'll need is an energetic kid, a tape measure, a stopwatch, and a safe place for your child to run. Calculating Speed 1. Pick out a "track" that your child can run safely. Select a distance appropriate for your child to run several times. 2. Help…
