The purpose of us feeling anxiety in our bodies is so that we will ‘DO SOMETHING’ to try to eliminate the event, situation or thing that we are worried about. This is a primitive and basic survival instinct that we still have deeply embedded in our brains. The problem is…we don’t need to run away from saber tooth tigers anymore!

However, instead of having the idea of “I need to get rid of this feeling” we need to change it to “whatever is happening right at this moment, I CAN HANDLE that.”

What we need to do is learn about anxiety and how it works in our bodies and then break anxiety down into small pieces, and take it step by step. It may start with learning about how anxiety works and feels in our bodies; the sensations we get from anxiety. Starting with what happens in our brain and body when we are anxious. Then we need to learn what we can do with those sensations to lessen them and our anxiety. Then we work on our anxious thoughts and work to change the dialogue we have in our heads about anxiety. Essentially we break anxiety down into small chewable bites. This is in order to give you some success.

Students teams determine the size of the caverns necessary to house the population of the state of Alabraska from the impending asteroid impact. They measure their classroom to determine area and volume, determine how many people the space could sleep, and scale this number up to accommodate all Alabraskans. They work through problems on a worksheet and perform math conversions between feet/meters and miles/kilometers.

This is an activity about ultraviolet light. Learners will make ultraviolet light detector bracelets and use them to experiment with artificial light and sunlight. Then, they experiment with various sun-blocking materials to see how such materials impact the beads' absorption of ultraviolet light. Special UV detecting beads are required for this activity. This is Activity 3 of the Sun As a Star afterschool curriculum.

Learners will use a variety of resources to conduct research to try to find answers to the questions they generated in previous activities. They continue to work the way scientists do by communicating what they learned from their research about Mars and present questions they still have and that others might want to think about researching in the future. This is activity 8 of 9 in Mars and Earth: Science Learning Activities for After School.

In this problem-based learning activity, students learn about global precipitation patterns. They assume the role of climatologists and teach a newspaper reporter about the scientific method, explore how rainfall patterns impact society using TRMM (Tropical Rainfall Measuring Mission) satellite data, and brainstorm needed weather instruments to be built in the future. The resource includes teacher notes, student worksheet, glossary and an appendix introducing problem-based learning. This resource is the third of the 3-part learning module, Investigating the Climate System:Precipitation.

This lesson plan helps students understand the factors that affect water quality and the conditions that allow for different animals and plants to survive. Students will look at the effects of water quality on various water-related activities and describe water as an environmental, economic and social resource. The students will also learn how engineers use water quality information to make decisions about stream modifications.

Students explore materials engineering by modifying the material properties of water. Specifically, they use salt to lower the freezing point of water and test it by making ice cream. Using either a simple thermometer or a mechatronic temperature sensor, students learn about the lower temperature limit at which liquid water can exist such that even if placed in contact with a material much colder than 0 degrees Celsius, liquid water does not get colder than 0 °C. This provides students with an example of how materials can be modified (engineered) to change their equilibrium properties. They observe that when mixed with salt, liquid water's lower temperature limit can be dropped. Using salt-ice mixtures to cool the ice cream mixes to temperatures lower than 0 °C works better than ice alone.

Today we're going to talk about a fundamental part of all modern computers. The thing that basically everything else uses - the Arithmetic and Logic Unit (or the ALU). The ALU may not have to most exciting name, but it is the mathematical brain of a computer and is responsible for all the calculations your computer does! And it's actually not that complicated. So today we're going to use the binary and logic gates we learned in previous episodes to build one from scratch, and then we'll use our newly minted ALU when we construct the heart of a computer, the CPU, in episode 7.

In this lesson about cosmic rays, students will describe why cosmic rays are dangerous to astronauts. Includes information about student preconceptions. This is activity 3 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation (CRaTER)."

Students determine the mass and volume of soil samples and calculate the density of the soils. They use this information to determine the suitability of the soil to support a building foundation.

Students learn that it is incorrect to believe that heavier objects fall faster than lighter objects. By close observation of falling objects, they see that it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

Students learn more about forces by examining the force of gravitational attraction. They observe how objects fall and measure the force of gravitational attraction upon objects.

Use the sliders in the Rose-Colored Glasses SIM to play around with different colors for the light source, the car, and the glasses to answer these questions and learn more about the concept of light and color!

We have also created a short (2:44 min) tutorial video that goes into more detail on how to use this SIM for both you and your students.

This task is designed as an assessment item. It requires students to use information in a two-way table to calculate a probability and a conditional probability. Although the item is written in multiple choice format, the answer choices could be omitted to create a short-answer task.

Science Background: Light travels in straight lines, and this activity allows students to observe light and think critically about how they experience light in their lives. A common misconception for students is that the light comes from their eyes to light up the object, so drawing rays as arrowheads that show the direction of the light is a key concept.
Materials: index cards, ruler, coloured markers or pencils, hole punch, sticky tack, drinking straw, flashlight or ray box, beaker or glass, water

Science Background: Sound waves behave in the same way as light and water waves. This activity allows students to “see” sound.
Materials: plastic wrap, small yogurt container, elastic band, 1mL salt, tuning fork, water

Student teams design and conduct quality-control experiments to test the reliability of several ultraviolet protection factors. Students use UV-detecting beads in their experimental designs to test the effectiveness of various types of sunscreens and sunblock. For example, they might examine zinc oxide nanoparticles versus traditional organic sun protection factors. UV intensity is quantitatively measured by UVA and UVB Vernier sensors, and students record and graph their results. By designing and conducting this experiment, students compare various substances, while learning about quality control.

In this episode we looked at robots and the engineering principles of robots. We learned how robots use sensors to interpret their environment, how actuators and effectors allow a robot to manipulate the objects around it to accomplish a task, and how computers coordinate the efforts of the two.
