06 Feb Science Update!

The 5th graders have been learning all about the movement of Earth in and through space–rotation, revolution, standard time zones, day and night, the seasons, and most importantly: learning how to find a specific spot on Earth using coordinates of latitude and longitude. This unit concluded with a test this week and leads us to a study of Minerals next.
The 6th and 7th graders are now familiar with the Periodic Table of Elements and can use it to look up the number of protons and electrons in a particular element. We have studied atoms, the law of conservation of matter, compounds, solutions, and chemical bonding. As of today we are learning how to balance simple equations. On Friday we conducted a lab to illustrate physical and chemical change. We dissolved epsom salts in water, then washing soda in water. These were simple solutions, where water acted as solvent and the salts and soda as solutes. The second part was to mix those two solutions and watch a chemical change occur when the two seemingly clear liquids yielded a very cloudy milk-like precipitate.
The 8th grade has been working on drawing elements using Lewis dot structures in order to illustrate ionic and covalent bonds. Our next unit will cover motion.
The Biology class has been hard at work on a multi-faceted project. Students were assigned individual biomes as topics, then created quick (5 minute) slide show presentations. The next part of the assignment asks the students to compile a more complete report listing characteristics, description, and animals/plants in their assigned biome. This report will include data on plant and animal adaptations and current threats to the biome along with suggested solutions. This report will go hand in hand with the slide presentation. Students will each prepare 6 possible exam questions (and provide the answers) for their respective biome. This unit will conclude with all students studying and learning from material researched and compiled by their classmates.
