Seeds & Plants (#9)

Seeds & Plants: Lima Bean Study: What happens when you soak a Lima bean in water for a few days? Before we placed them in water we made designs and took measurements of our Lima beans so we could compare what they look like after.  The Lima beans almost doubled in size! It was also easy to remove the bean's outer shell and split the bean in half. The bean now had a little sprout growing! If we planted this, the sprout would continue to grow into roots and a steam and form leaves and more beans! Seed Discovery: Explore a variety of seeds, guess what plant the seed is from, measure and compare different seeds.   Classroom Resources for Seeds and Plants: Watch a green bean seed germinate, develop roots, and finally sprout, with the Life Cycle of a Green Bean set.  Root-Vue Farm has a viewing window which makes it easy to watch the roots develop underground! See carrot, radish and onion seeds grow up as the roots...

Landform Dinosaurs (#20)

Creating Landform Dinosaurs Each student was given an index card with the name of a landform on it. They were asked to draw a picture of the landform and give information about it.  Next students were asked to create a dinosaur using as many landforms to create the body as possible. This was my groups landform dinosaur Another awesome landform dino Andy the T-Rex Landform dino Frederick the Dinosuar Landform Resources: Dinosaur Posters Dinosaurs Description Cards Landforms Landform Cards Children's Books Related to Landforms and Dinosaurs:

Rocks and Minerals (#21)

Quartz:   Quartz one of the most common minerals on Earth, you can find it in sand and most types of rock. It is made from a chemical compound called silicon dioxide. Quartz is piezoelectric, which means if you squeeze a quartz crystal, it generates a tiny electric voltage. The opposite is also true, if you apply a voltage to a piece of quartz, it vibrates at a precise frequency. Quartz watches work in a very different way to pendulum clocks and ordinary watches. The gears are regulated by a tiny crystal of quartz instead of a swinging pendulum or a moving balance wheel. Inside a quartz clock or watch, the battery sends electricity to the quartz crystal through an electronic circuit. The quartz crystal oscillates (vibrates back and forth) at a precise frequency: exactly 32768 times each second. The circuit counts the number of vibrations and uses them to generate regular electric pulses, one per second. These pulses can either power an LCD display (showing th...
