DAY 1 Life Science-Today the students learned about the differences between spiders and insects and the insect's compound eye. They dissected an earthworm and a sea star and prepared a microscope slide with a plant petal or leaf before viewing it under the microscope. A goat kid visited us to start the day and helped us learn about the ungulates-split toe animals- whose group also includes sheep, deer, and camels. The students created their own fossils in a clay mud and used a seashell or turtle shell to make an imprint. The fossil clay was then changed through pressure and heat like in the real Earth processes and students are able to see that sometimes the initial impression changes also making identifying what they are seeing difficult.

DAY 2-Earth and Space Science- Today we explored space by taking a virtual tour given by astronauts on the International Space Station, tried some dehydrated foods like they have in space. We learned about the constellations and created our own constellation pattern with glow in the dark beads the students can view at night. For our Earth Science we studied how our fossil imprints were changed by heat and pressure like experienced in the Earth's crust and mined for Iron Pyrite (Fool's Gold). We made our own watermelon flavored taffy to assist us in studying the layers of Earth and each student tried removing a dinosaur bone from our dig site game.

DAY 3-Physical and Chemical Science- Today we began with physical science concepts of sound and light. Students got to try two types of sound tubes to create different pitches and learn about the way our ear transforms the sound waves into a recognizable word or sound in our brain. The singing snake egg shaped magnets were a favorite as students explored the magnetic poles and the sounds made when repel or attraction force made the magnets turn or vibrate to align the poles. We learned that light also travels in waves, but their are different types of light rays. We viewed real x-rays and made our own sunprint photo paper x-ray of a starfish. Next, we explored chemical science. We learned about the pH scale when we used a gummy paste created from carragan that is boiled out kelp (different from gelatin because it can be reheated to gel and un-gel then gel again). The students then added a sour lemon powder to the outside to move to the acidic end of our pH scale. To explore the reaction between an acid and a base, we mixed vinegar and cornstarch to show how a chemical reaction occurs and stops when the reactants are used up. We then added seasalt to the mixture to explore differences in the density of fresh and salt water and the effect it has on the buoyancy of an object. Our final chemistry project of the day was making a slime that can bounce and be stretched. the day ended when students got to view the lizards, leopard frogs, and baby dog sharks the 4th-8th grade camp will be dissecting on their life science day next week.

DAY 1-Life Science-Today students learned about cell membranes when we viewed the slides they prepared of brine shrimp eggs. We placed water outside of the egg and were able to view cell transport under the microscope as the water moved through the cell membrane. We also worked with the Phylum- Chordata today. We studied the classes amphibians, reptiles, and fish by learning about characteristics specific to them.Each student was able to view many of these characteristics by dissecting a lizard, a leopard frog, and a 22 -inch dog shark. We also viewed some National Geographic footage on prey and predator in an encounter between a dogshark and giant octopus and watch how sharks use their body parts and hunt near the Great Barrier Reef near Australia.

DAY 2-Earth and Space Science-Today we started growing our own crystals after discussing the types of rocks and found in the Earth's crust. We made watermelon taffy to demonstrated how the layers in the Earth's crust are folded due to heat and pressure as well as movements along fault lines. We demonstrated how intrusive and extrusive rocks are formed and effect the geologic dating of rocks by making a small volcanic reaction and having the reactants press against our salt dough to create impressions and run through the dough layers. Next, we moved on to space and had dehydrated food that the astronauts eat for our snack. We learned about light years and how we use them to measure the distances of stars from Earth. We learned aboout constellations and how to determine the position of the planets Mercury, Venus, and Mars within a specific constellation based on the date. Students were able to use the astronomical star gradian to find their date of birth and see how their birthdate got its astrological sign based on which planet was placed inside a constellation on that date. We prepared a hydrophobic polymer sand to simulate the dry surface found on Mars.

DAY 3-Chemical and Physical Science-Today we learned about polymer science and bonding. We began the day by creating a polymer gel that we molded and dried into a bouncy ball that has the physical property of glowing in the dark. We also made a mixture that was like the first fire extinguisher foams and used a salt to stop the reaction. This was interesting as we got to watch the foam expand when hitting the air and change from a liquid to a solid. We used a nitrogen based fertilizer to show the reactions between acids and bases and between two acids. We used a contained light to study how light is absorbed and not allowed to escape from a black hole and did a challenging cube puzzle for the students to put back together to demonstrate how ion bonding with cations and anions takes place. As part of our physical science we made our own bubble gum to explore physical and chemical properties of matter. We also explored force and motion by "playing" with a jumping frog toy, a pendulum, a sound clacker, magnets. We used a rattle back rock to demonstrate the mineral properties that turn the rock to face North even when we have spun the rock in the opposite direction.
