10 Fun Science Lessons

http://www.discoveryeducation.com/teachers/free-lesson-plans/classroom-planetarium.cfm

Classroom Planetarium: In this lesson students will learn the relationship between the planets in the solar system by creating a 3-D model. Students are given balloons and told to blow them up all different sizes to represent the planets. Students will use "space paste" with newspaper and paint to make the balloons look more like planets. Once the planets are finished you will use fishing line and clips to hang them from the ceiling.

Rules of Forces and Motion: Students will explore force, gravity, friction, and speed by doing an experiment with ramps and toy cars. Different materials and other factors will be used to discover what causes a car to go faster/slower and farther.

Taste Illusion: Students taste and record the flavor of two cordials, one green and one pink. The trick is, they are both the same exact flavor. The green cordial just has food coloring added. The green cordial has the appearance of a lime flavored drink, so students are more likely to expect it to taste that way, and they may even be able to trick their brains into thinking it really does taste like lime.

The Phenomenon of Sound: Waves: This experiment will help students be able to see sound waves, which are normally unseen. Students will observe sound and the way it travels. The first experiment is to observe what happens to paper clips when they are placed on a drum and you bang on it.

In Which Liquids Do Seeds Grow Best?: Students will observe the stages of plant  growth to see in which liquids plants grow best. The liquids used for this experiment are milk, iced tea, vinegar, orange juice, club soda, and water. Bean seeds will be used as the plant for this experiment. Each student will fill in a chart to record their daily observations of each plant.

Smelling Test: Students will use their sense of smell to identify different objects. Be sure to use strong scented items that will be somewhat easily recognizable to children.

Levitating Ice Cubes: This experiment requires a cup of water, string, ice cubes, and salt. Without the addition of salt, the string will not stick to the ice cube. This cool experiment shows students how salt lowers the freezing point of water, allowing the ice to melt slightly and cause the string to stick.

Musical Bottles: What better way to learn science than through music?! Students will use glass bottles filled with different levels of water, each turned a different color with food coloring, to create the first six notes of the musical scale. Working in groups, students will then try to figure out how to use the bottles to play the tune of "Mary Had a Little Lamb."

Make Your Own Thermometer: This is a great way to teach kids about temperature and how thermometers work by creating their own. All you need is a jar, a straw, some clay, and rubbing alcohol. The hotter it is, the more liquid will be pushed up into the straw.

Unearthly Eggs: Did you know that arches have incredible strength? In this experiment, students will discover the strength of arches by using regular store-bought eggs. Empty the contents of the eggs and cut them in half so they are dome shaped. Students can then decorate their egg domes and use heavy books to test their strength.
