He cleans the scrape and then pours hydrogen peroxide on it to kill bacteria that might infect the wound. When the hydrogen peroxide touches his wound, fizzy bubbles form and bacteria die. What is happening? A B C D change of state chemical change mixture formation physical change 3rd Grade 5 Answer Johnny scrapes his knee. He cleans the scrape and then pours hydrogen peroxide on it to kill bacteria that might infect the wound. When the hydrogen peroxide touches his wound, fizzy bubbles form and bacteria die. What is happening? A B C D change of state chemical change mixture formation physical change Remember, some of the clues that a chemical change has happened are: gas forming (bubbles), color change, heat is produced or a new substance is formed. 3rd Grade 6 Question The picture to the right shows a food chain.

Which list shows the order in which energy flows through this food chain? A owl, mouse, clover, sun B clover, mouse, owl, sun C sun, clover, mouse, owl D mouse, clover, owl, sun Remember, the source of all energy is the Sun. 2nd Grade 3 Question Look at the picture to the right. About a kilometer away, a huge rock falls off a cliff. It makes a loud crashing sound when it hits the ground. Who will hear it first, and why? A The boy sitting up, because his ears aren’t blocked by anything. B The boy underwater, because sound travels fastest through liquids. C All will hear it at the same time, because the speed of sound is constant. D The boy with his ear to the ground, because sound travels fastest through the solid rock. 2nd Grade 3 Answer Look at the picture to the right. About a kilometer away, a huge rock falls off a cliff. It makes a loud crashing sound when it hits the ground. Who will hear it first, and why? A The boy sitting up, because his ears aren’t blocked by anything. B The boy underwater, because sound travels fastest through liquids. C All will hear it at the same time, because the speed of sound is constant. D The boy with his ear to the ground, because sound travels fastest through the solid rock. Sounds travel fastest through solids (rock) and slowest through gases (air) 2nd Grade 4 Question Which landform was formed by a glacier, through erosion and deposition?

C mutualism D parasitism Million Dollar Question Grade Level 11 1,000,000 Question Tom is doing an experiment. His hypothesis is that water runs through gravel faster than it runs through sand or clay. The diagram shows his setup. He plans to pour equal amounts of water into the top of each container and then time how long it takes for water to begin dripping from the bottom of each. Tom puts the same amount of soil in each container. The soil is held in the containers by identical squares of cloth kept in place by rubber bands. The containers are fastened to ring stands. List at least 3 variables in Tom’s experiment. Put a star next to the manipulated (test) variable. 1,000,000 Answer Some of the variables are: Type of soil Amount of soil Amount of water Squares of cloth Containers Ring stand Rubber bands Time for water to go through the soil OK smarty pants! What can Tom do to improve his set-up so that his tested variable is the only thing tested. Thanks for Playing Bonus: Tom should make the containers the same size.
