Q: How do earthquakes occur?
A: Earthquakes occur when some plates of the earth’s crust get stuck and stop moving then suddenly jump back and the sudden movement causes the earth’s surface to shake violently.

Tadpole
This Tuesday, Cassie, Ray, Olivia, Mom, and I went to Irvine Regional Park to catch tadpoles and caterpillars. There was a stream and mom had her good boots on and Cassie had to carry her across, which it was hilarious. Too bad we didn’t have a camera with us. I caught three tadpoles, Cassie caught three tadpoles, mom and Olivia caught like ten tadpoles (with Casie's help), and Ray caught... (pause for dramatic affect)... ONE tadpole, isn’t that amazing, ONE tadpole. There is only only two still living. Tadpole update to come at a later date.
We have a lot of caterpillars. They have survived so far. We are still not sure if they will make it. Caterpillar update to come at a later date.

Fun with Science By Caleb
We are having fun with grandma and science. We made bombs out of plastic bags, warm water,baking soda, vinegar, and a tissue. We also made rock candy but we kind of cheated and ordered the package instead of making it out of stuff we already have.

Science Day -Cassie
“My Favorite experiment on Science Day. Why?”
My favorite experiment on "Science Day with Grandma" was the balloon experiment. This is how it works. You get a clear glass bottle and put about 1/8 cup of water. Then, put a tablespoon of honey in the bottle, put a pack of active dry yeast into the bottle and shake it up really good. After it’s all mixed together, stretch a balloon and put it on the top of the bottle (oh, and you should have taken the lid off the bottle). Set a timer for 30 minutes. After the timer goes off, check on the bottle and see what happened. The balloon should have blown up a little, and if you want you can keep the balloon on for a long time and see how big the balloon will get.
“Why it works”
The yeast eats the honey and creates gas and causes the gas to rise in the balloon. The balloon rises and expands. Bread works the same way. The yeast eats the honey and creates gas and the bread rises.
“Science Day”
So on Science Day (with Grandma) we made bread and we did the balloon experiment. It was so much fun!!! -Cassie

Egg burst by Caleb
We did an experiment called "Egg Burst". We thought it would work because we followed the instructions perfectly. We put the raw egg in vinegar and waited for a couple of days. The acid in the vinegar dissolved the eggshell. Then we put the egg in water. The water molecules are smaller then the vinegar so it goes through the egg membrane and it expands until it explodes, but our egg never did. So, I got a pencil and poked it. It popped and we were happy.

Bumblebee Bat by Caleb Rizio
Bumblebee bat and its natural habitat
The bumblebee bat is the smallest bat in the world. In fact, it is the smallest mammal in the world. It has 1 baby a year. It is an endangered species mainly because of humans burning the forests near there home.It is 1 inch tall and they have a wingspan of 7 inches long.
It weighs .07 ounces and it is reddish/brown in color, and has a pig like nose.
It is located in limestone caves in Thailand and Myanmar.
It only flies at dusk around teak trees and clumps of bamboo capturing insects for food.
The Kitties Hog Nosed Bat is so cool and is my favorite bat in the world.

Cassie's Bee Hummingbird Report
Bee Hummingbirds
Bee Hummingbirds are the smallest birds in the world. They are as big as a large bee. A Bee Hummingbird can flap their wings 80 times per second, so their wings look like a blur to human eyes. They feed mostly on nectar, and occasionally an insect or spider. They eat small bugs for the protein content they provide. Calories from nectar and sugar water in hummingbird feeders is used to power hummingbirds. Their tongue is shaped like a long tube, so it is like drinking from a straw. The Bee hummingbird picks up pollen on its bill and head, when it flies from flower to flower it transfers the pollen. In one day the Bee Hummingbird can visit 1,500 flowers. Hummingbirds live in a nest year-round in trees. A regular hummingbirds nest is tiny, it is about the size of half an English walnut shell. The outside of their nests are usually made with moss and plant fibers. The rest of the nest is made out of plants and spider webs. Hummingbird’s predators are sharp-shinned hawks, praying mantis, largemouth bass, green frogs, bull frogs, and big orb-weaving spiders. So Bee Hummingbirds have to be careful of their predators because they are so small.
