We have been learning about properties of matter and two of the properties that we have focused on are electricity and magnetism. Here are some of the things we have to say about those topics...

We went to the lab today and explored the concept of relative density. Here is what the class has to say...
The kids have spent the last several days collecting data about how long a fidget spinner will spin. Here is a sample of some of their graphs!
Here at Paradise Intermediate we are learning about lab safety. We also learned that lab safety is important and rules are made for a reason. Some of the rules are never eat in the lab, don't lick or eat ANY chemicals at all. Never horseplay or run around the lab. One more we thing we learned was how to use a triple beam balance.
by Lilly, Gracie, and Wyatt We have learned about many properties that matter can have, so we set about separating a mixture of salt, gravel, magnetite, and wood chips using what we knew about properties. Knowing what would dissolve, what would float, what would evaporate, and what would stick to a magnet made it easy! We explored the concept of density in the lab. We learned that things that are more dense will sink and things that are less dense will float. The most shocking items we explored? The sponge. Almost everyone thought it would float. But, when we squeezed all of the air bubbles out of it, the sponge sank! This week we spent a lot of time in the science lab exploring mixtures and making solutions. We started out by observing gravel, Kosher salt, and diatomaceous earth. Then we added water to each one and stirred. The gravel and the diatomaceous earth both just made a mixture which we could separate using screens and filter paper. The salt made a solution. The only way we could separate it was by letting the water evaporate. Then we tested sugar, baking soda, flour, pepper, and drink mix to find out which ones made mixtures and which ones made solutions. We spent a tough week learning how to design an experiment. We learned that the starting question has to be testable, which means it can only be answered by doing an experiment that compares two or more things. We learned how to write a hypothesis using the phrase "If...then...". We learned about variables. Did you know you can only change one thing in an experiment? Everything else stays the same! And, once we finished with our experiment, we learned that a conclusion was much more complicated that just saying we liked the experiment and can we do it again sometime. We started the year learning about the life cycle of a butterfly. We have several passion flower vines growing on our playground fence and Painted Lady butterflies LOVE passion flower vines. On Tuesday the students went outside and collected larva (AKA caterpillars) for the classroom and used their iPads to take pictures of all of the different stages. We found eggs, larva, pupas, and adults. We even found adults emerging from their pupa cases with wrinkly, wet wings! We can't wait to see what happens to the larva we collected for the classroom! Here are some of iMovies that the kids made about metamorphosis. After learning about food chains and how energy flows through an ecosystem, we made food webs today that show how all of the organisms in an ecosystem are interconnected. |
Every great advance in science has issued from a new audacity of imagination. AuthorWe are the 5th graders at Paradise Intermediate. Join us on our science journey this year as we stretch our imaginations and make new discoveries! Archives
