Pablo Alvarado-Cruz Earth Space Science Assignment Part I Evaluate Experiments Choosing: Scenario 1 Christopher and Kate noticed that after a rainstorm some of the rocks in their yard appear to shrink. They wondered how the mass of the rocks changed when dissolved in water. To determine this, Kate purchased a variety of rocks from a local shop, carefully recording the types of rocks in a data chart. Christopher gathered rocks from the backyard to add to the rocks Kate purchased. They measured each rock s initial mass; then they inserted the rocks one by one into 100 milliliters of water and measured the mass of each rock after it had sat in the water for five minutes. Both Christopher and Kate concluded that store-bought rocks do not†¦show more content†¦After I will record the type (name) of each rock since not all rocks will dissolve as much as the other rocks. Then I would record the starting mass of each rock and place the rocks in water for 5 minutes. After the rock is taken out after the 5 minutes I will record the ending mass of the rock to see if it’s mass c hanged. The controlled variables in this experiment would be the rocks I’m using since I can’t change the type of rocks I’m using. Part II Designing an Experiment Choosing: Problem 1 Your family has planted a garden. You observe that some of the plants in the garden have teeth marks in them. What is eating the plants? Purpose: My family has planted a garden, observing some of the plants in the garden, we realize they have teeth marks in them. What is eating the plants? Observation: Me and my family observe where the teeth marks are, what type of plants have teeth marks and the size of the teeth marks. Research: In the step, we can take a look at how big the bite size marks were and determine which type of animals it could be. Also, depending on which plants were taken bites out of, we can research what type of animal eats what type of plants, then seeing how big or small the bite marks are, we can have a realistic understanding of what type of animal was biting the plants. Hypothesis: I believe a small animal like a bunny might be taken nibbles from my plants since we grow carrots but there may also be a few other animals going to the garden sinceShow MoreRelatedWhy Philosophy Is Still Necessary986 Words   |  4 Pages As I was attempting to brain storm for this assignment, I ran out of ideas so I decided to read the prompt again and again for inspiration and hopefully some new ideas.
