Elephant's Toothpaste - Kid Version - The Lab

Each student should have in front of them a cake pan, plastic bottle, Dawn in small cup, food coloring, 1/2 cup peroxide, and the dissolved yeast mixture. 2. Stand the bottle up in the center of the cake pan. Put the funnel in the opening.


Simple Mechanics. Cams The basic principle of the cam is to turn a circular motion into a linear one.

Simple Mechanics

This is referred to as reciprocating movement. In it's simplest form you turn a handle to make something move up and down. The cam-follower is connected to, and part off, a shaft known as the Push-Rod. BBC Earth - Timeline - The Earth formed from a vast gas and dust cloud. From the Big Bang to Me.

How Was The Earth Created?

This is an important question. A question that helps us understand our own origin as a race of sentient, thinking beings. Did the Earth always exist? Has our planet spent eternity orbiting the Sun, quietly unchanging? These are difficult questions to answer. TED-Ed and Periodic Videos. Can Project-Based Learning Close Gaps in Science Education? Putting kids to work on meaningful projects can transform classrooms into beehives of inquiry and discovery, but relatively few rigorous studies have examined how well this teaching method actually works.

Can Project-Based Learning Close Gaps in Science Education?

An encouraging new report describes preliminary, first-year outcomes from a study of 3,000 middle school students that shows kids can, in fact, learn more in science classrooms that adopt a well-designed, project-focused curriculum. When researchers analyzed test scores from those classrooms by students’ gender and ethnicity, there were no differences in learning performance. That’s a preliminary indication that high-quality project-based curricula might be able to help narrow the science education achievement gap in children from low-income backgrounds or other groups that are underrepresented in STEM fields.

How well the benefits hold up or grow in the second year of implementation remains to be seen. Access to good science curriculum materials is a “vexing issue,” Harris said. Milk Jug Skeleton. Fun Science Experiments for Kids. A Milk Jug Skeleton is a Fun Recycled Craft Decoration for Halloween. Years ago I created one of these Milk Jug Skeletons for Halloween.

A Milk Jug Skeleton is a Fun Recycled Craft Decoration for Halloween

Just recently I was cleaning out my craft room and came across the directions again and thought I would share for those who have never seen it before. My Milk Jug Skeleton I think got lost in one of my many moves years ago and now that I have found the pattern I think I may have to create another one. This Skeleton would be a craft for an older child or adult since there is a lot of cutting involved, but it is well worth the effort. Not only does it look cool, but you are also recycling all those Gallon Milk or Water Containers into a Halloween Decoration that is sure to bring lots of conversation when the Trick or Treaters come to the door.

Learn about Position, Velocity, and Acceleration. Plant structure bi. Seed Plant Overview: The plant body consists of two basic parts--- the shoot system and the root system Shoot system is above ground and includes organs such as leaves, buds, stems, flowers, and fruits The functions of the shoot system include photosynthesis, reproduction, storage, transport, and hormone production The root system is below ground and includes roots as well as modified stem structures such as tubers and rhizomes The functions of the root system include anchorage, absorption, storage, transport, and production of certain hormones Seed plants contain 2 types of vascular tissue (xylem & phloem) to help transport water, minerals, & food throughout the root & shoot systems Plant cells have several specialized structures including a central vacuole for storage, plastids for storage of pigments, and a thick cell wall of cellulose Plant cells are all box-shaped in appearance Meristems: Root Tip with Meristems Specialized Plant Cells: Parenchyma Cells Collenchyma cells Dermal Tissue:

Interactive Rock Cycle Animation. Newton's 3 Laws of Motion. Motion: Laws of Motion. There was this fellow in England named Sir Isaac Newton.

Motion: Laws of Motion

A little bit stuffy, bad hair, but quite an intelligent guy. He worked on developing calculus and physics at the same time. During his work, he came up with the three basic ideas that are applied to the physics of most motion (NOT modern physics). The ideas have been tested and verified so many times over the years, that scientists now call them Newton's Three Laws of Motion. The first law says that an object at rest tends to stay at rest, and an object in motion tends to stay in motion, with the same direction and speed. You can see good examples of this idea when you see video footage of astronauts.
