In Week 10 of our science starters, we focus on observing objects, events, and patterns, recording both qualitative and quantitative information. Pistol shrimps possess extraordinary abilities to shoot supersonic blasts, allowing us to make intriguing observations. Additionally, hippos sweat a unique red fluid that protects them from sun damage and bacterial growth. After watching videos related to these phenomena, students are tasked with developing qualitative and quantitative observations, distinguishing facts from inferences, and formulating researchable scientific questions.

  1. Science Starters Week 10 Review

  2. Observe objects, events and patterns and record both qualitative and quantitative information. Pistol Shrimps are tiny creatures with a deadly weapon. They are capable of shooting supersonic blasts from their fingertips with enough force to instantly stun or kill their prey. Watch the video and write down 3 qualitative and 3 quantitative observations

  3. Distinguish between factual statements and inferences. Write down 3 factual statements and 3 inferences from observations of the photo.

  4. Observe objects, events and patterns and record both qualitative and quantitative information. Watch the video and write down 3 qualitative and 3 quantitative observations

  5. Formulate research questions and hypotheses This is what happens when you run water through a 24hz sine wave. Come up with 2 questions when watching this video? Which are researchable by science? If neither are, come up with a third that is.

  6. Formulate research questions and hypotheses Did you know that hippos sweat red? They have been known to sweat a red fluid that was once thought to be blood! More recently, however, scientists have discovered that their sweat actually protects against sun damage and prevents the growth of bacteria on the skin. This properties probably evolved from the need to protect them from the harsh sunlight they spend their days in. It also helps to heal and prevent infection in wounds, which is useful in a species that fights as much as they do. Basically, they've evolved a colorful antibacterial sunscreen! Develop one researchable question from the information above. What makes a researchable question, scientific?
