HANDS-ON LAB SKILLS and SCIENCE INQUIRY Predictions Based on Patterns Scientists often make predictions based on all the things they already know are true. Predict means to tell what you think is going to happen. Scientists then test their predictions to see if they are right! Let’s check what we have learned so far: What does the word ‘predict’ mean? Tools Used by Scientists Scientists use MANY different tools while they are observing and conducting experiments. Let’s explore some tools scientists use. Scientists use a RULER to measure the length of an object that is small, like an eraser. Scientists use a METER STICK to measure the length of an object that is large, like a table. © Copyright NewPath Learning. All Rights Reserved.

Scientists use a MEASURING CUP to measure how much of a liquid there is. Scientists use a CLOCK to tell the time and to measure how long it takes to do something. Scientists use a HAND LENS to see something up really close. © Copyright NewPath Learning. All Rights Reserved.

Scientists use a THERMOMETER to measure the temperature outside and inside. Scientists use a BALANCE to measure the weight of an object.

Sorting and Comparing Scientists often compare and sort objects based on color, shape, texture, size and weight. These objects are sorted according to their COLOR. These objects are sorted according to their SHAPE. Sometimes objects are compared and sorted according to their TEXTURE too. Texture is the way something feels. The rock on the left has a smooth texture, and the rock on the right has a rough texture. Sometimes scientists compare objects according to their SIZE. If a scientist sorted objects according to their WEIGHT, she would need a scale or a balance to see how much the objects weigh. © Copyright NewPath Learning. All Rights Reserved.
