Earthquake Waves

The general properties of waves can be investigated through an activity on earthquakes. First, have your child research the three different types of earthquake waves. Encourage them to find the following information about each wave: 1. name of the wave 2. how quickly it travels compared to the other two 3. what part of the Earth does it travel through 4. type of wave, based on motion (compression wave, transverse wave, etc.) 5. does it…

Rotational Motion with a Pinwheel

Kids love to play with pinwheels. Whether you buy one at the store or make your own (pinwheel making tutorial), add a little Physics to the fun! 1. Use a string and ruler to measure the outside distance around the outside of the pinwheel. 2. Mark one spot on the pinwheel in some way. Use color, a piece of tape, etc. Just make sure the mark is very visible, even when the pinwheel is spinning.…

How do colors affect temperature absorption?

We've all heard the fashion sayings . . . "never wear white after Labor Day" . . . "pastel colors should be worn at Easter" . . . etc. You know the traditions, but did you know they are actually based on science? The color of the clothing you wear can affect how hot or cold you feel when standing outside during the day. The light reaching us from the Sun is known as "white…

Learning about Buoyancy in the Pool

Buoyancy seems like a simple concept, but to fully understand it on a scientific level can be a challenge for students. Introduce the concept to your younger elementary kids in a fun way while playing in the pool this summer! Buoyancy is based on Archimedes' Principle that states, "Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." Very…

Teaching Kids about Consumerism and Conservation

Let's face it, the advertising world targets your kids every day. What child hasn't been disappointed after saving for months for a toy, only to find it doesn't measure up to what the commercial promised? In my science classes I teach my students how science can be used to objectively test claims made by advertisers . . . in other words, how to be wise consumers. Here's a fun idea that actually came from one…

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…

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…

Make Waves in the Tub

Light waves . . . sound waves . . . it's all pretty hard for a younger elementary student to understand. They can see light and hear sound, but the wave part just isn't something they can perceive with their senses. A good way to begin to introduce the topic of waves is with water waves. A wave that is visible and moves slowly enough for them to observe the actual wave itself. Use bath…

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…

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…
