Flowers

Imagine for a minute that you are walking through a field of flowers. Imagine all of the different colors, shapes, and smells. Now think about why different flowers have different colors. Why do they have different shapes? Why do they small different?

Orange Slices

This is a cool science trick that will let you know the number of sections in an orange (or other citrus fruit) before you slice it. It makes a fun trick that seems like magic, but is actually just a matter of careful observation.

Seed Search

When an animal reproduces, its offspring eventually wander away to find their own home. With a plant, once it starts to grow, it is usually stuck in that spot. That makes it important for plants to have ways to spread their seeds over a large area. In this video, we will explore some of the different ways plants accomplish this.

Feeling a Point (or two)

How do you feel? No, I don't mean are you happy or sad? Touch the back of your hand. Did you feel it? How? When you touched your hand, you pressed on nerves in your skin. These nerves reacted and sent a message to your brain, telling you that something touched your hand. Some parts of your skin have more nerves than others. We are going to examine how these nerves are arranged, and see how that can affect the message that your brain gets.

Cat Wiggles

If you have ever watched a cat preparing to pounce on its favorite toy, you may have seen it wiggle its back legs from side to side just before it leaps. Why do they do that? It would seem that the movement would alert their prey, so there has to be a good reason for the behavior. To understand that, we need to learn a bit about muscles and tendons.

Cat Lapping

This experiment comes from a recent event in the science news. Researches have discovered that cats drink in a very different way from dogs and other mammals. Now you might think that things like this had been completely explored decades or even centuries ago, but high speed photography has shown us things that we did not suspect before.
