Always be positive. en-us 2017-04-18 03:17:30 UTC 2025-11-28 15:02:45 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Rocket.png 353059 https://padlet.com/353059/iqs9a7lngx3b/wish/166667547   Matter can be a solid, liquid, or gas. Solids have a definite volume and shape. Liquids have a definite volume but not shape. Gases however do not have a definite shape or volume.
   Mass is the amount of matter in a object. You can find the mass by multiplying the volume and density of an object.

   Relative density is the amount of matter an object has for its size. Foam has particles that are evenly parted so that it can float. However, metal has tightly packed particles so it sinks.

 Solubility is the ability to be dissolved. A solute is a substance that dissolves in a solvent. A solvent is a substance where a solute dissolves in.

   Magnetism is an object with has an magnetic field that is attracted to magnets. For example, iron, cobalt, and nickel are magnetic.

 Conductors are objects that allow heat to pass. It can allow electricity depending on material. Insulators does not allow heat to pass through easily. Such things like wood and rubber.

 Light energy is radiant energy that our eyes can see from the visible part of the electromagnetic spectrum.

 Electrical energy is the energy is probably the most known. It is energy produced by moving electrons.

   Mechanical energy is energy produced by a machine or moving part like our body.

   Sound energy is produced from vibrations you can hear. It can later die out from traveling in air.

   Thermal energy or heat energy is energy that causes a transfer of heat between materials.

Reflection are energy waves of light energy bouncing off the surface of an object. Refraction are the energy waves that bend or change direction and speed as they pass from one type of object to another type.

 You can demonstrate refraction of light are glass that are called lens. Lens that are curve outward are called convex lens. These lens make objects look larger. Lens that curve inward are called concave lens. They make objects look smaller.]]> 2017-04-18 03:28:55 UTC https://padlet.com/353059/iqs9a7lngx3b/wish/166667647 353059 https://padlet.com/353059/iqs9a7lngx3b/wish/166667674   When sediment layers pile up, the bottom layers are pressed down by the weight of the layers being added on top. The minerals that were dissolved in the water fill in the spaces between the sediments, cementing them together to form sedimentary rocks.

Fossil fuels are nonrenewable resources made from the remains of plants and animals buried in Earth's crust that is used to produce heat and power.]]> 2017-04-18 03:29:17 UTC https://padlet.com/353059/iqs9a7lngx3b/wish/166667674 353059 https://padlet.com/353059/iqs9a7lngx3b/wish/166667733    A trait is a characteristic of an organism. An inherited trait is a characteristic that has been passes from parents to offspring during reproduction. Acquired traits are physical trait that has been earned or acquired. Things such as an injured wing, a broken leg, or a scar.

 A behavior is what an organism behaves. A inherited behavior is when an organism gets its behaviors from its parents. A learned behavior is when an animal behavior that was develops from observation or instruction rather than being passes down by heredity.

   Alternative energy resources are materials from Earth that can be replaced by nature within a short period of time.

 Other resources are wind, solar, geothermal, and hydroelectric energy.

  The Moon, Sun, and Earth are in charge of the Moon phases. The Sun's light bounces of the Moon to Earth. While the light is reflected, the Moon revolves around the Earth creating the eight phases of the Moon, known as the Lunar Cycle. It cycles through every 29 days.
 
  The Moon and Earth make ocean tides. On Earth, there are two high tides and two low tides. They are caused by the gravitational pull of the Moon and is basically the repeating rise and fall of water at bays and oceans. Neap tides are the lowest tides while spring tides are the highest. It occurs every day.

  The seasonal cycle is made with the Sun and the Earth. When the Earth revolves around the Sun on its axis, four seasons occur every year. The four are spring, winter, fall/autumn, and summer. The revolution time is 365 1/2 days.

 The day and night cycle happens with the Sun and Earth. As the Earth rotates on its axis, one side faces the Sun. This side is day. The other side which is dark is night. This pattern occurs every 24 hours or one day.

   Another pattern that occurs with the Sun, Earth, and Moon are eclipses. When the Sun, Moon, and Earth are aligned in that order, it creates a Solar Eclipse.
