Our project is making a lava lamp in a bottle. My group members are Erik Duarte‚ Isaac Sanchez‚ Kenneth Loya‚ and Nick Mahan. Our question was can you make a lava lamp out of household items. Our hypothesis was you can if you find the right items. We were right you can if you put vegetable oil on top of water and then put the food coloring in and the ad Alka-Seltzer. Our background info is that vegetable oil is used to cook‚ water you used to drink and stay alive‚ food coloring is used to make

such an beautiful sight! If only we could visit there. Could we? Maybe so. In 1925 President Calvin Coolidge declared Lava Beds a national monument which I understand why. Even though its a "secret" park of volcanic rocks and many underground caves it is full of history and geological wonders. As a student at Atkinson County Middle School I believe that going to the Lava Beds National Monument would be and excellent opportunity for us eighth graders to learn about how it was created and formed

Lava This presentation will discuss two questions which are How is Lava Produced? And What hazards/dangers does lava pose? It will also study one example of a Lava Flow in Hawaii. Lava is molten rock expelled by a volcano during erupting. It is produced/ formed in the interior of planets including Earth and their satellites. When the lava is first erupted from the vent in a volcano otherwise known as the volcanic vent‚ lava is a liquid and varies from 700°C to 1‚200°C. Although lava is

module. Likewise‚ the tail lamp is replaced with a 10mm red LED. The battery pack is a combination of five 1.2V‚ 600mAh Ni-Cd cells‚ connected in series to produce an output of 6V DC. When you ride the bicycle‚ the dynamo touching the wheel spins around and diodes D1‚ D2‚ D3 and D4 form a bridge via which buffer capacitor C1 charges. When the dynamo voltage is sufficiently high‚ the low-current 5V relay energises and the DC supply available across C1 is routed to the head lamp (LED1) driver circuit

Bubbling Cabomba pondweed Teaching Notes Introduction Like many other water plants‚ Cabomba has specialised tissue called aerenchyma that allows gases to diffuse inside the plant. Aerenchyma provide buoyancy and allows oxygen transport to the submerged roots that may otherwise be in hypoxic (low oxygen) conditions. If you cut through the aerenchyma‚ oxygen can escape. This can be made use of this in the classroom to show how the rate of photosynthesis is affected by light intensity or by
