Beneath Our feet
Experiment 1: We put different types of rocks in to three piles that were called Igneous, Metamorphic and Sedimentary. Igneous comes from a volcano. Metamorphic is heat and pressure and Sedimentary is a mixture of conglomerate, fossils and layers.
Experiment 2: We put chalk and 3 spoons of sand into a cup and shook it really hard. Some of the sand turned pink which was the colour of the chalk. It also became softer and smaller.
Experiment 3: Our group had a bag of crystals and then we put some water in the bag, then we left the bag for a few minutes and then we came back and it was slush.
Experiment 4: Our group had a piece of paper and a tub of water and a cup of salt. We put a little bit of the paper into the water with the cup of salt and then we waited a little while and then we came back and the water had spread to the top of the paper.

I learned that if you shake the chalk with sand the chalk will end up small and will have little holes in
Rocks also do not have crystalline structure. Rocks also can include fossils where minerals cannot. Minerals colors are generally the same. Rocks vary in color.
I always knew heat caused things to dissolve faster, similar to how things melt faster the higher the temperature gets above their melting point. I included an extra reactant in my second experiment because I was interested in seeing how that would affect the
I can interpret that if a snail is presented with both leaves then it will only eat the plain leaves and not the striped leaves. It doesn’t eat the striped ones because it knows that a clover that can produce cyanide is striped and therefore poisonous, so it tends to stay away from it. That’s why the snail didn’t eat the clover the plain leaf that was painted with white stripes. From the wild it knows not to eat striped leaves. It’s pretty much like a visual warning.

Sedimentary facies changes may show if there was a transgression or regression and can be identified on whether there are coarse-grained sediments such as sand, which indicates they are nearshore, in high energy environments. Or if they are fine-grained sediments like muds and silts, they indicate offshore, deep, low energy environments. List and discuss in detail major problems that had to be overcome by plants and animals in order to live successfully on land. Give examples. Discuss how life has evolved from the ocean during the Paleozoic to move onto
One of the best feeling that i get comes from my favorite place. It’s the batter's box i love the feeling that comes along with being their. Your team cheering for you or you smacking a ball. You learn and have an amazing time in the box it might not always go your way but that is the learning part of it.
I think that things have changed because Bryce has changed his feelings towards Juliana completely since the beginning of the story because he now likes Juli, feeling the need to defend her and her family, and feels very guilty about the things he has done to her. One point that proves that Bryce has changed his feelings towards Juli is that he now likes her. Proof of this is on pages 6 and 123. On page 6, Bryce says, “I still has enough sense at age seven and a half to know that Juli Baker was dangerous.” This shows that Bryce wanted nothing to do with Juli and he wants to avoid her.
The chalk tends to be very fragile and as stated before, it will fall right off the paper. Degas did this piece in layers and found a creative way to keep it in tact. He was using a fixative that allowed him to create many layers of pastels on top of each other without disturbing the intensity of each color. It has been said that the formula for his fixative was lost. He used hatching, which is the use of closely placed parallel lines.
Another type of layer is called the Terrestrial Fossils. In this layer there are several rock layers and fossils that form this whole layer. Some layers are called the Hermit Shale, Supai Group, Coconino Sandstone, and Surprise Canyon Formation. There are many types of fossils called leaves, Tracks, and Dragonflies.
When sidewalk chalk was invented, no one could have foreseen the future it would have on mankind. A scientist developed a new adaptation to sidewalk chalk that would allow the art to come alive. It became the most popular toy in nations all other the world. Children would see the commercials on the television and beg and plead for their parents to get them a set of this revolutionary chalk. Two months after it was invented, the revolution occurred.
Giving the audience a deeper understanding, Barry uses examples of what questions might arise in an experiment. Taken from the text, “A shovel can dig up dirt but cannot penetrate rock. Would a pick be best, or would dynamite be better—or would dynamite be too indiscriminately destructive?” (Barry). Throughout this passage Barry uses vivid images of a rock to display the effectiveness of questions a scientist might face.
8) Explain how each experiment type (question 7) differs from the
For example, an experiment similar to this one could be how pressure could affect the time it takes for an Alka-Seltzer tablet to dissolve. Using A flask and rubber stoppers, you can compare the amount of time it takes for and Alka-Seltzer tablet to dissolve in regular room temperature water and room temperature water in a flak but with a rubber stopper stopping the air flow into the flask. This is related to the experiment performed above because the increase in pressure from the rubber stopper stopping the air flow in and out of the flask may affect the time it would take for the Alka-Seltzer tablet to dissolve. Another example of an experiment related to the one performed above is how the amount of water used to dissolve an Alka-Seltzer tablet effects the time it takes for one to dissolve. This also relates to the experiment performed above because it also affects how fast the rate of reaction is.
