VanCleave's Science Fun

ABOUT THE SOUND PICTURE

With mouth wide open, vibrating air coming up the throat from the vocal chords leaving the open mouth and spreading in all directions. Hi, I am Janice VanCleave, author of 50+ best-selling science experiment books for children ages 4 through high school. I taught science for 27 years and now am creating this science website.   My scream was not staged. The picture was to be of two adult cats, which I was holding. A microsecond before the camera snapped, the two cats dug their claws into my skin as they prepared to leap out of my arms. A picture like this is great for making inferences. Kids could make "guesses" as to why I am screaming. They would be drawing on facts from the photo, such as I look like I am in pain or maybe I am just pretending.

Ratios

By

A ratio is the  relationship between two amounts.  A ratio can be expressed as a fraction. What comes to mind is icing cupcakes. If I use one cup of vanilla cake icing to ice 4 cupcakes, and one cup of chocolate icing to ice 2 cup cakes, which cup cakes have more icing on them, […]

Inertia

By

What is the difference between these science terms: inertia, mass, weight? Inertia measures how difficult it is to move an object. Mass measures how much material is in an object. Weight measures the force of gravity acting on an object. Often times referred to how heavy an object is. Problem: Compare Freddie (a small stuffed toy) […]

Science Project: Fireflies

By

The National Children’s Museum in Washington, DC in collaboration with the Museum of Science in Boston invite kids of all ages to participate in a special science project. Kids are to collect specific data about the  fireflies in their their own backyard.The project launched June 29, 2009 and you may join in anytime. For specifics […]

Jupiter’s Bruise

By

This colorful photo of Jupiter, the fifth planet from the Sun, was taken from the Hubble Telescope. Notice the area on the lower right side of Jupiter. This is where fragments from a comet collided into the giant planet in July 1994. This was a thrilling and a once-in-a-lifetime opportunity for scientist  to watch comet […]

Sparklers

By

We in the United States are making preparations for a July 4th celebration. This always brings thoughts of family picnics followed by firework displays. In some areas fireworks are not allowed except by professionals who prepare brilliant, colorful displays. While in other places, even small children are allowed to participate in this pyrotechnic event. If […]

Celebration Pots

By

These kids are decorating clay pots, which will be used to celebrate July 4th. The pots will be filled with soil and instead of holding lit sparklers in their hands, the sparklers will be stuck in the soil inside the pots. The pots can be set at a distance from the kids–not too far and […]

Mnemonics

By

The human brain can more easily remember meaningful information. This explains why kids can sing every word of a song they like but have a difficult time learning information for a math or science test. But then there are lots of things we might be interested in and cannot seem to have instant recall on […]

Song Birds

By

Birds, such as the mockingbird (left)  are born with the ability to sing, but they must learn the songs of their species. If a baby bird is isolated from other birds of its species, it can instinctively sing simple songs, but not the more complex songs of its species. These it must hear and learn. […]

Butterfly Puddling

By

Butterflies use their long feeding tube, called a proboscis, to drink the sweet nectar from flowers. While they get the sugar they need, nectar is lacking in some important nutrients needed for reproduction. For these necessary salts and other nutrients, butterflies, mostly males, sip liquids from mud puddles or any moist area where soil might […]
